What does it mean to speak and not simply talk? Does it mean you croak back with ravens? Or does it mean that ravens croak back with you?

I have spent many hours on many days for many years speaking with ravens. It’s not easy though to learn a new language, and their patience with my workshopping is not high on their honey-do list. Nevertheless, I work on it every chance I get, and they humor me with free lessons and bountiful harvests of humility.

Before you can speak though, you must first listen. Hear what dialect they speak because they do differ. Do their calls sound like mercury dropping into a still pail of clear cool water, or a porcupine purring as a trusted one scratches an old itch with gentle trepidation? Perhaps this raven growls in fours, fives, and sevens. Perhaps it mimics the locking door beeps it learned from the untrusting cars at a dusty desert gas station. Any way they call though, don’t forget that they do so without lips. When you call back, remember to curl yours back to show your own black beak. It also helps if you look friendly, so maybe give them a smile, too.

What I’ve learned from years speaking with ravens, is that they enjoy engaging with us wilderness tourists just like how I imagine the French mock Americans who ask simple questions through their noses while in berets at the Eiffel Tower. The ravens, still like how I imagine the French, will chirp or croak or clop back at you, but always faster than you thought you had tacitly agreed to. Can’t you hear that I’m not a native speaker, and can’t you respect that I’m at least trying? Oh, they can and they don’t. That’s the humor.

Sometimes they’ll throw new words your way, too, and always with a gleam in their eye. Just as you’re learning how to hock “hello,” they’ll pop quiz you and bleet back, “howdy,” “hey there,” and “greetings puny earthings,” just to smile to themselves at your dense bones and plucked, useless wings. To you, they may all sound like new noises. To them, they’re new jokes. Even when they start to cackle at my attempts, in time I’ve learned to cackle at myself, too. The lessons go on.

So next time you’re high in the mountains or deep in the desert and find yourself startled by a raven asking what life is like from way down there on the target range, listen first. Hear for the intonation, the subtleties in rhythm and iridescent syncopation, and their sandstone timbre. Then simply repeat after them. Curl your lips back, clench your larynx, and croak. Taste a new language. Harness the moment as a shared moment. Allow yourself to be the wild echo of a wild raven. Soon, you’ll find that when you speak the right language, ravens will give your own wild echo back. So now the question arises: will allow yourself to continue learning to speak with ravens, or will you simply settle to talk amongst your fellow puny earthlings?

Few birds have such a strong association with one plant that the plants name becomes part of the birds name. Sage grouse is one, Acorn Woodpecker another, but the Pinyon Jay is our topic today. Pinyon Jays are usually found in close association with pinyon-juniper forests throughout the Great Basin and the nutritious nuts of the pinyon pine are their preferred food. The blue and grey birds collect and cache pinyon nuts in summer and fall for later consumption. They have an uncanny recovery accuracy and excellent spatial memory, which allows them to rediscover these scattered caches and eat pinyon nuts all year. They do not recover all the stored seeds, however, and therefore aid in the dispersal of pinyon pines.

Pinyon Jays have a complex social organization and are highly gregarious. [Pinyon Jay Audio Courtesy Kevin Colver]

They spend their lives in large flocks of up to 150 or more individuals. Nesting is communal, although rarely are there more than 2 or 3 nests per tree. Breeding season is in late winter. Many birds spend their entire lives in the flock into which they were born.

Pinyon Jays are not migratory, but they tend to be nomadic; traveling to wherever there is a good crop of pinyon nuts. They will also eat a wide variety of seeds, insects and berries to supplement their diet and can be found in adjoining sagebrush, ponderosa pine forest and riparian habitats. The conservation status of Pinyon Jays is considered vulnerable. Destruction of pinyon-juniper forests for grazing and changes in fire regimes have resulted in loss of habitat. And what is a Pinyon Jay to do without its pinyon nuts?

Hi I’m Holly Strand.

Every year, just before Christmas, I comb through the house looking for presents hidden earlier in the year. I check inside old shoes, unfold towels in the closet, and peer way back into the dark recesses of seldomly-used cabinets. With a child in the house, you have to be tricky! The problem with this complex gift stashing behavior is that sometimes I forget where I hid the present when it’s time to wrap it! And once in awhile I forget that I bought something at all! Out of sight—out of mind!

You wouldn’t make a very good magpie, I have been told. For magpies– along with jays, crows and ravens, are masters at hiding–or caching as it’s called– and then retrieving. Of course, what they cache is not Christmas presents but food.

One Utah bird that is much admired for its caching and retrieving skills is Clark’s nutcracker . This large jay lives in mountainous areas throughout the west. Experts say that Clark’s nutcracker can cache 10s of thousands of pinyon, whitebark or limber pine seeds in a single season. Starting in August, the bird will hide 1-15 seeds at a time, often distributing them several kilometers and at much different elevations from the original tree. Caches lie 1-3 centimeters deep in forest litter, bare soil, under bark, in holes, in logs or stumps.

As winter wears on, the nutcracker will retrieve its caches with the help of visual landmarks such as rocks, trees or logs. Using these visual cues, the nutcracker will retrieve the seeds through summer of the following year. Forgotten or abandoned seed caches often germinate, growing into trees that produce more food.

Just as I worry about prying eyes when I hide Christmas presents, birds who cache must be careful to notice who is watching. The common raven is notorious for its spying and thieving behavior. One raven will covertly observe while another caches scraps of meat, eggs, bones or seeds. The observer will then shamelessly raid the cache usually within a couple of days. But having probably raided someone else at some point, the caching raven is on the lookout too. If the caching raven senses the presence of a would-be looter, it might wait for the other bird to become preoccupied. Or it may move the food to a different site altogether. Caching ravens will also hide behind some structure to avoid being seen.

Interestingly, these sly birds will even engage in fake caching. Ravens will cache inedible or low value food items in plain view of other ravens but then stash the good stuff in secret. Fake caching seems designed to throw looters off track, . But perhaps it’s also a character test for fellow ravens? Or maybe—for the intelligent raven—it’s all just an amusing shell game?
