Vote for the 2016 Walnut Label

Windscorpian   
It's walnut harvest time. There's going to be a big crop and lots of neighbors and friends to share the bounty. Everybody gets to vote on the critter that goes on the label for the 2016 Dipper Ranch walnuts. Usually the label features one of the snakes that appeared on the ranch during the year, but there weren't many snakes this year. Why? Maybe because of the gray fox family that moved into the barn. Yes, foxes eat snakes. If you don't believe me, check out this video from the Camera Trap Codger.

I'm stubborn and even without a huge selection of snakes to choose from this year, I am not going to put some cutesy animal on the label. Instead, you get to choose among local animals I saw in 2016 which have a reputation of being creepy or strange, but really aren't. Mostly reptiles, spiders and bugs, but also some strange mammal tricks.

Vote for the 2015 Walnut Label

2015 Snake #1 The Golden-Eyed Rattlesnake - third of four rattlesnakes moved from the farmyard in two days in March and an especially dark one showing off its rattle at the release site (A Pile of Rattlesnakes). 
Here are photos of snakes we saw on the Dipper Ranch in 2015. Vote for your favorite below. The snake with the most votes will be featured on the label for the 2015 Dipper Ranch walnuts. I will randomly select one of the voters to get a prize -  a bag of delicious shelled walnuts.

What kind of crazy idea is this - snakes on a walnut label? You'll just have to go to past walnut label contests to get an explanation and see the snakes featured on prior labels:

Climate Change Made Me Do It

A sapsucker stretches after its winter arrival at the Dipper Ranch orchard.
This one looks like a cross between the red-naped sapsucker and the red-breasted sapsucker.  
Me in October:
Hardly any walnuts have fallen on the ground at the Dipper Ranch and they're all pecked open by birds. There will be no walnut harvest party this year.  It must be the four-year drought. The walnut trees leafed out in June this year - two months late. It must be climate change.
 The Dipper Ranch walnut trees in December:
Here's a few thousand walnuts on the ground for you. Sorry, dropped them in their husks this year. And it's going to rain soon so you better pick them up before they mold. Isn't climate always changing?

Vote for the 2014 Walnut Label


Juvenile western yellow-bellied racer pulled from the main springbox on October 22. Will this be the last snake observed on the Dipper Ranch in 2014?  Contestant #1   
Bits of rain but the hillsides are still dry and warm. It doesn't feel like fall except for the early dark evenings. Still, some seasonal patterns carry on despite the ongoing drought. The red-breasted sapsuckers squeak as they peck away in the persimmon tree during the day, and the leaves rustle when the gray foxes leap into the tree to eat persimmons at night. The English walnuts are falling behind the barn. There hasn't been enough rain to knock off their outer green husks, nevertheless, I find brown walnut shells a quarter mile down the road with just one ragged hole in them - ravens. If we don't get more rain soon, us humans will get black fingertips when we peel off the green husks to get to the tasty walnut meat.

Sharpy Wins

Forest sharp-tailed snake showing its ladder-striped underside, sharp-spined tail,  orangish lateral stripe, blunt nose and overall small size.
The sharp-tailed snake squeezed ahead as the favorite choice for the label on the 2013 Dipper Ranch walnuts.  All-in-all, it was a great choice.  Who knows when I will see another sharp-tailed snake on the Dipper Ranch? And it was exciting to document it as the forest sharp-tailed snake species. I was pushing to pick a rattlesnake in the superstitious belief that maybe if a rattlesnake was finally on the label, no rattlesnakes would show up at the farmhouse next year.  Hah!




Snake video follows.

The 2013 Walnut Label Runoff

A top view of the forest sharp-tailed snake showing the red-brown line down each side, spine-tipped tail, and blunt nose.  
The 2013 walnuts have been harvested and I've cracked the first batch.  They're yummy as usual.  But I can't make the 2013 Dipper Ranch Walnut label yet because there is a tie between people's favorite snake to go on the label. So I figured I would share a few more photos of the two remaining contestants: #2 the forest sharp-tailed snake and #9 the crenulated rattlesnake from the springbox.

Vote for the 2013 Walnut Label

Not an advertisement for Stihl helmets, just a place to keep a small California mountain kingsnake safe while putting down the Stihl brushcutter. Amazing how the colors match.  
It's that time. Walnut harvest time. I was expecting a small crop this year since last year we harvested over 200 pounds from two trees, but the yard behind the barn is littered with  English walnuts while the first batch is drying in the guest bedroom.

The dusky-footed woodrat who lives in the barn is pleased to know this. So are my co-workers and neighbors who are coming to harvest walnuts, watch the sun set, and potluck it.

Walnut harvest means it is time for the annual reader poll. From all the snakes seen at the Dipper Ranch this year, you get to vote on which one will be featured on the 2013 Dipper Ranch Walnuts label.

Snow Moon

Full moon through California buckeye tree at the Dipper Ranch, February 25, 2013
Late February's full moon is the Snow Moon.  In central coastal California, we had snow for about 4 hours this winter.

I meant to photograph the full moon just as it was coming over Georgia's Ridge. I was inside getting ready by cleaning my best lens only to get distracted by amazing reflections of the cowboy light in the newly cleaned lens.

The King of Walnuts


The California mountain kingsnake has been elected by popular vote to be the Dipper Ranch snake featured on the 2012 Dipper Ranch walnut label. Thank you readers for your votes and delightful comments. I can see that you relish the diversity of snakes in our California coastal mountains as much as I do.

NEWS FLASH - I've seen two more snakes since November 18th when I predicted the California nightsnake would be my last 2012 snake sighting on the Dipper Ranch. The snakes should be tucked away in their winter beds by now, right? Until a series of intense storms shook things up in late November. At times, the rain was falling so hard that the slopes became super-saturated and slipped and oozed beneath themselves.

Vote for the 2012 Walnut Label


The walnut crop at the Dipper Ranch is huge this year. The guest bedroom is crammed with English walnuts drying in trays, box lids, buckets, and bags while Mango and Cole guard the harvest from mice.  Every year (well, almost every year), we pick a photo of a different Dipper Ranch snake for that year's walnut label. Vote for the snake to be featured this year and you may be the lucky person to whom I give a bag of shelled walnuts.

Vote for the 2011 Estate Walnut Label

English walnuts still in their green husk.
Every year, we harvest English walnuts from the two trees behind the barn.  I give many of the walnuts away under the label of Happy Snake Ranch Walnuts.  Somehow, that tradition just got started and you to get vote on this year's label.

Seasonal Attention Disorder


Sunset 11-05-10
One day too early for the walnut harvest party

The clouds are back.  I say that every year, don't I?  After the summer dry season, the tinted, shape-shifting clouds highlight the huge space looming above us, and then by association, the curved earth we scratch upon.

Pretty sunrises start the day and spectacular sunsets inspire evening thoughts.

Vote for 2010 Estate Walnut Label


Every year, we harvest English walnuts from the two grand trees behind the barn.  I give many of the walnuts away under the label of Happy Snake Ranch Walnuts.  Last year, we made a party out of it with guests, sunsetting, an appearance by the Deer Whisperer, and I boldly claimed that these are Estate Walnuts.

With the arrival of the 2010 storms, the walnuts are dropping and it is time to decide on the snake to be featured on this year's label.

The 2010 candidates are:

Estate Walnuts

--The very first yellow-bellied racer I rescued from the Dipper spring box. ---

The English walnut trees at the Dipper Ranch are productive every year. The walnut bounty is enjoyed by family, friends , neighbors, co-workers, volunteers, jays, deer, rodents, even delivery guys and coyotes. But not by snakes. Nevertheless, somehow I started making labels for the walnuts that feature a Dipper snake of the year.


Estate bottled wines are defined as those for which 100% of the grapes are grown on land owned or controlled by the winery within the same viticultural region, and the winery must crush and ferment the grapes, and finish, age and bottle the wine in a continuous process on their premises. Since all the Dipper walnuts are from within 100 feet of my kitchen door, they dehusk themselves on the ground under the trees, I dry them between old window screens under the maple trees or in the garage, and I shell them while watching DVDs in my living room, I hereby declare these are Estate Walnuts.


I don't expect to ever run out of walnuts, snake photos or snake stories on the Dipper Ranch, so there will probably be many interesting Estate Walnut snake labels. One day, they will surely become collectibles.

Today while I was sprawled on the forest floor photographing a huge oak, someone who doesn't know me very well tried to scare me about snakes. I told him "It's too cold for snakes. They are all hibernating." An hour later, we were walking through a sunny meadow and sure enough, there was a gopher snake peering up at me. I moved it out of the way of the ATV. As the last of its tail slithered into the dry grass, I smiled to be humbled by lowly snakes once again.

Harvest Time 2009

--- Nathan and his very bright grandfather.
Photographer: Duncan Simmons ---

Last weekend, the first batch of friends and warriors came up to the Dipper Ranch to harvest English walnuts. A good time was had by all and then we had jello. No, wait, this is California. We grooved on the yellow fall light behind the red barn as we plunked the walnuts into buckets, bags, t-shirts and wheelbarrows and sang. No, just I sang and just inside my head because I was so happy to share that plunk-plunk sound.

We had several novitiates. I carefully explained the technique: pick up the brown-shelled ones and put them in the wheelbarrow. Don't pick up the other ones because the green husk will turn your hands black. Soon the wheelbarrow was full and everyone was giddy with walnut greed.

--- Walnut from 2009 harvest on left; 2008 walnut on right. ---

Last year, the walnut harvest inspired me to start the Dipper Ranch Blog. The Dipper Ranch Blog is now officially one year old. Happy Blog Birthday.

After wheeling the barrow around the farmyard, the silly people started playing walnut barrowball. The rest of us compared the color and taste of the new harvest (still a little green) with the few remaining unshelled nuts from last year's harvest (slight sawdust taste). Do vintners do this when they bottle a new year's worth of grapes?

--- Drying walnuts between window screens ---

I reminded people to dry the harvested walnuts for several days before they start shelling them and to only store the unshelled nuts in paper bags. I spread my walnuts on screens to air dry for about a week. I like to dry them outside under the shade of the maple trees, but if rain or high winds are forecast, I dry them in the garage. I spread them out in one layer on old window screens and then clamp another screen on top of them. This is to prevent the scheming rodents from stealing my harvest.

--- 2 x 2 buck overseeing the retreat of does into the forest. ---

After the harvest, we went for a walk to see the sunset. We saw the 2 x 2 buck and several does on the upper meadow, but since I had a large group of people with me, I was not concerned that the buck would try to charge me again. The does slipped into the forest and the buck stood on the edge to make sure we did not steal any of his girls. We ignored him and walked out to the center of the meadow for the best view of the sunset over the ocean 12 miles away.

--- The buck sidesteps in Duncan's direction. ---

Somehow, Duncan became separated from the rest of the group. When I looked back across the large meadow, I saw that the buck was circling him. I was concerned since Duncan was squatting down. The buck never actually ran straight towards Duncan as he had charged me in the same meadow at sunset last week. Instead, he slowly circled Duncan with lots of sideways glances, and then trotted over the top of the hill.

--- Duncan, stand up! ---

--- From Duncan's viewpoint.

Later when I informed Duncan that was one of the bucks that charged me last week, he said, "Oh, that is because he knew you are pushover." Duncan Simmons, attorney-at-law and deer whisperer.

We had BBQ hot dogs, sausages and chicken with pesto noodles, almond-stuffed olives and cherry tomatoes by candlelight under the maple trees. Benny fixed my computer. Everyone drove home safely and agreed that a good time was had by all.

Nathan, with energizer-bunny-like stamina, was excited to pee in the back-forty, and he gave me a giant pumpkin with a ghost carving kit. I don't get any trick-or-treaters at the Dipper Ranch, so at first, I didn't know what I was going to do with these prizes. Since then, I have secretly schemed to roll the huge pumpkin down the steepest hill on the ranch and watch it tumble and smash into little treats for the deer. A former news station camera man has offered to document this important event. Do we know how to party or what?

--- Colorful sunset clouds to celebrate the harvest and the great outdoors.
Photographer: Duncan Simmons ---

With the next windstorm, there will be more walnuts on the ground. With sunny days, the green husks will shrivel and more brown shells will pop out. And another batch of daytime friends and warriors will arrive for the walnut harvest. At night, the critters will collect their share; how they party, I am not sure, but I'm sure a good time will be had by all.

Garage Ecology

I've been cleaning the garage in preparation of the annual walnut harvest. I found an old radio in there. It probably belonged to Paul Ortega, the ranch caretaker who lived in this house for decades. On top of the old radio, I keep a pair of muddy glasses which I found in the dirt behind the barn last winter. Every time it rains, something shows up in the farmyard. The glasses remind me that we all grind down to dust one day, except for the junk we lose in the yard.

I assume these glasses were Paul's along with the muddy tools which keep showing up. I put the rusty tools in a bin in the garage with the mental label "Paul". The broken plates and glassware, I pile in a pot full of herbs with the mental note "Lola" (Paul's wife). I browse through Paul's bin now and then when I am thinking about what life used to be like on the ranch. Lola seems to be a constant pink presence in the yard. I am hesitant to clean the radio or the glasses because Paul touched them. I really don't know these things, but I make up stories about found items in an attempt to understand the past and to fit in with the time I sense flowing through this land.

--- Bucks and does gathering at the courting oak within earshot of the garage. ---

Farmyard deposition goes something like this: Paul loses tools in the farmyard while working, they get covered up with mud, more rain uncovers them decades later when Cindy finds them, Cindy puts them in the garage with all the other stuff that collects dust and requires annual cleaning, Cindy loses her stuff in the yard, somebody else finds them later, and so on. Be careful of what you lose in the yard because that will be your legacy.

--- Bucks passing calmly today. ---

Somehow this radio manages to tune in only AM talk shows from the 50s and 60s. An investment program ("Buy this book and you will be a millionaire.") and a Christian station ("Shameful dancers on the sidelines of football games") got me through cleaning up a lot of mouse poop.

--- Does resting on the other side of the hill. --

Meanwhile, through the open garage door, I could see the deer gathering under the courting oak. I kept an eye on the bucks, but today they repeatedly passed each other with no signs of aggression. The does were disappearing over the hill behind the courting oak, so I took a break from sorting nails to climb its back side and spy on them - the does were resting and the bucks were hanging out. Later, I noticed that the 4 x 4 buck was gone and the 2 x 2 buck was scent-tracking the does with outstretched neck. Below the house in a meadow, I could see a small male fawn attempting the same thing. The does just keep moving and grazing and ignoring the attention. I guess something happens eventually since there are new fawns every year.

--- Bucks don't seem to eat or rest much during the rutting season. ---

--- 2 x 2 buck steadfastly following a doe. ---

When dusk arrived, I turned off the radio in the hopes of hearing owls. I'd just gotten back from an animated talk by Garth Harwood to the South Skyline Association on Owls in Your Neighborhood. Within minutes, a big chunky owl landed on the utility pole in the orchard. I prepared my ears for detecting what species of owl it might be. Probably a great horned owl because of its large size, but possibly a long-eared owl which Garth says occasionally visits the Santa Cruz Mountains. And also to see if I could distinguish the higher pitched call of a female great-horned owl during the male-female duet. There's nothing like applying newly gained nature knowledge in your own backyard while cleaning the garage. Garth said the great-horned owls are starting their pair-bonding activities this time of year prior to breeding which consists of repeated calls back and forth. This explains the loud hooting from the maple trees next to my bedroom which have woken me up several times in the last few weeks. The owl gleaned his feathers, ignored my unsuccessful attempts to photograph him in the dark, hunted in the grasslands, but didn't bother to call.

--- Blurry large owl with ear tufts. ---

Later while sweeping the garage floor, I heard a loud crunching noise in the backyard near the two smaller walnut trees. As I walked in that direction, I heard the familiar sound of a deer trotting off. The deer are visiting the yard regularly, especially at night, to snack on the fallen walnuts. While I got distracted by star-gazing, the crunching started up again. Curious, I went inside to get a flashlight and waited. When the loud sound started again, I shined the light and was surprised to find a coyote under the walnut trees. He slipped away but at the spot he was standing, I found walnuts cracked open. I looked around and found more cracked shells with the nut meat missing.

--- To be tested for coyote saliva. ---

The Silva family used to own this land. The Silva girls told me their uncle planted the walnut trees behind the barn in the 60s and the nuts were a special heart shape and extremely tasty. They inquire how the walnut trees are doing, and I take the hint and walk across the country road with a big grocery bag of walnuts every year.

This is garage ecology:
The Silva uncle planted the walnut trees, Paul Ortega took care of them, now I harvest the walnuts and give many away, and every year the deer, woodpeckers, jays, crows, mice and coyotes visit the trees for an autumnal feast. While the fundamentalists pray on the radio, the deer court openly, the owls don't give a hoot, and generations of coyotes walk over buried tools and plates to crack open walnuts.

Part IV - Cracking the Nuts

I spend winter evenings cracking walnuts while I watch movies. Then I seal the kernels in vacuum-packed pouches and store them in the freezer or give them away for holiday presents.

This is my cracking technique. Line up the nutcracker perpendicular to the slit in the shell. Grasp the free ends of the walnut firmly in your other fist (even tighter than shown in the photo) and gently apply pressure with the nutcracker just until you feel the slit widen and hear the first crack. Roll the walnut 180 degrees and reposition the nutcracker diagonally across the top and bottom of the shell. Slowly apply pressure again until you hear another crack. Usually by this point there are enough cracks in the shell that you can pull one hemisphere off and then firmly pluck the nutmeat out of the remaining cup of the shell. Either pull out the papery packing tissue between the kernel halves or use your fingers to split the nutmeat in half and flick off the packing tissue which should be brown and stiff if the walnut is ripe.

I challenge myself to crack the walnut shell so the kernel comes out whole. Then the nutmeat looks like a brain with its wrinkled double hemispheres. Indeed, in the 16th and 17th centuries, herbalists encouraged the eating of walnuts to boost one's intelligence and heal other ailments of the head and heart. Modern-day research has found that walnuts are loaded with omega-3 fatty acids and have multiple health benefits (www.walnuts.org).

Other animals frequently harvesting both acorns and walnuts on the Dipper Ranch are deer, Stellar jays, scrub jays and ravens. If I sleep late on these brilliant autumn days, the Stellar jays get me up by rapping shells on the roof to peck a hole through to the nutmeat. On the other end of the day, the deer gather in the willow thicket below the barn at dusk, waiting for their chance at the walnut-strewn yard. Since the deer rutting season and acorn drop occur at the same season, careful driving is required this time of year as the deer recklessly cross roads at night to socialize under their favorite oak trees. The deer look ridiculous eating acorns. To eat these big nuts, they must open their mouths so wide, they lose all their daintiness.

Everywhere I go these days, I carry bagfuls of walnuts and give them away. The birds are carting off acorns overhead to family and hiding places. It's amazing these trees can produce so much food in their own little packages.

One final amazing fact about acorns - you can make a loud whistle with an acorn cap.

Part III - Harvesting & Hoarding


Every few days between Halloween and Thanksgiving, I scoop up any brown shells from the ground under the walnut trees and toss any fallen nuts still encased in hulls against the red barn to let the outer coating weather itself off. That way, I avoid staining my hands black from the phenol chemicals in the hulls. Some people use walnut hulls for making black or brown dye.

I wonder if the chemical in the walnut hulls also reduces the number of predators willing to chew through to the nut. Squirrels seem to be immune. Although English walnuts are not native to the North American continent (they originate from southwest Asia and are sometimes more correctly called Persian walnuts), our local wildlife collect them from yards and orchards. Squirrels are famous for stripping my friends' urban walnut trees. I am fortunate that the farmyard is surrounded by a broad band of grassland which the native western grey squirrels are not willing to cross from the hillside forests. There are, however, rodents that apparently collect walnuts at night because throughout the winter I find emptied shells in the barn with small holes chewed through the end.

Most nuts for human consumption need to dry for days to weeks before they are eaten. Last winter, I dried my walnut crop in the garage in open cardboard boxes covered with metal wire refrigerator shelves. Eventually, however, rodents raided the stash and the garage floor was strewn with broken shells. At first I couldn't figure out how the mice got the fat shells out of the boxes which were still sturdily covered with the wire shelves. Then I decided extra skinny mice had been assigned the mission to slip through the wires, crack the nuts inside the box and toss the pieces through the bars to their hungry families waiting outside.

This year, I am pouring the collected walnuts onto an old screen door suspended between picnic tables under the maple trees. I clamp a set of window screens on top to discourage raiders. So far it is working, although at first, I expected to hear crashing noises from the clever raccoons unscrewing the clamps some night. The raccoons (who ate my entire pear and persimmon crops this year) haven't shown up, so maybe their smirky mouths and sneaky hands aren't strong enough to crack open walnut shells. I hear the great-horned owl every night now, and sometimes a pair of screech owls, so they must be keeping the skinny mice away.

Every few days, I turn the walnuts to ensure thorough drying. It's a meditative process rolling the walnuts and lining them all on their long sides so the top screen will clamp down firmly. The other day while I was rolling walnuts, the local flock of acorn woodpeckers landed in the maple trees above me, chattering about their day of acorn harvesting. It reminded me about their special techniques for storing and drying acorns in a pecker-made granary.

Acorn woodpeckers work in extended family groups to harvest acorns and store them in their own granaries - tree trunks, power poles and fence posts that they have riddled with long rows of holes. They check the granary every day and since the acorns slightly shrink as they dry, the woodpeckers will move any loose acorns into tighter holes to prevent other animals from robbing their stash. I haven't found the acorn woodpeckers' cache on the Dipper Ranch, however, every morning they visit the maple trees by the house and conduct a short shouting match with the earlier arriving Stellar jays, so the yard must be somewhere between their nighttime roosts and granary trees. (Painting of acorn woodpecker above by Bob Hines, United States Fish and Wildlife Service)

Ninety-nine percent of the US supply and two-thirds of the world supply of English walnuts are produced from extensive orchards in the Central Valley of California (www.walnuts.org). Commercial harvest of walnuts is largely mechanized. First the orchard floor is rolled or dragged clean, then the walnuts are knocked loose from the trees by large shaking machines, and finally the fallen walnuts are blown into a row and swept up my mechanical harvesters.

I'm glad I get the chance to pick up the walnuts by hand. They make a lovely sound when they plunk into the bucket and many of my friends and family while talking to me on the cell phone in the fall, exclaim, "I hear walnuts. Will you save me some?"

For a hilarious description of the hippy lifestyle of California's acorn woodpeckers, see the Bird Watcher's General Store.

Part II - The Nut Leaves Home


By late summer, plump green hulls hang heavily in the walnut canopy. As the hulls slowly split, they reveal promising peeks of brown shells. By early fall, the hulls release their cargo and brown shells plop to the ground. On windy days, some nuts may drop still encased in their hulls.

In our area, the general order that acorns ripen in the fall is valley oak, black oak, tanoak, coast live oak, and then canyon oak. The acorns of species in the white oak group take 6 months to ripen (pollinated in spring, full acorn formed in subsequent fall), whereas acorns of the black oak group take 18 months to grow and ripen. On branches of the black oaks, you will find first-year acorns looking like shingled buttons, and second-year acorns fully formed. The first crop of acorns dropped is usually the damaged acorns, ones with weevils or mold or otherwise underdeveloped. They are still good eating for wildlife, but if you are collecting acorns to grow oaks, wait a few weeks for the second drop when the healthy, heavy acorns are finally released from their caps and fall and roll to their future destination.

Part I - A Sum of Nut Parts

English walnuts have 3 layers: the outer fleshy hull, the hard woody shell, and the inner eatable kernel. If you have just seen walnuts in holiday baskets, you wouldn't know about the thick, green hull that has to peel open to release the brown-shelled nut. As an extra layer, the hull discourages early consumption of the nut from some bugs and other potential consumers.

The acorn seed is enclosed in a leathery, bullet-shaped casing that emerges from a shingled cap. Each oak species has an acorn cap with a slightly different design, their own signature beanie or architectural roofline. The cap depth can vary from shallow to deep and the shape of the shingles covering the cap can be distinctly flat or warty depending on the species of oak.

Both the walnut hull and the acorn cap derive from bracts originally enclosing the flower buds. These plant parts modify their function through the reproductive stages, first protecting the developing flower (and perhaps controlling the timing of wind pollination in a way that may increase the genetic diversity or food quality of the seed crop) and then protecting the fertilized seed as it swells with food transported from the mother tree and stored in the developing nut - future nourishment once the nut breaks away and starts its separate life or becomes a menu item.
