How does the mighty oak create more oak trees? By making acorns.
But here’s the thing about acorns: they are heavy! (I know this because I’ve had a few fall on my head.) They are too heavy to blow on the breeze, so they plunk right down to the ground. Right under the tree. Here’s another thing about acorns: they need sun and water and room to grow. And how can they get that if they’re laying on the ground in the shade with all the other acorns? Well, if they’re from the white oaks next to my house they get picked up and moved by squirrels and birds, carried away, and buried in the ground.
And sometimes those acorns get forgotten and they sprout into tiny oak seedlings (I know this because I’ve had more than a few grow in my vegetable patch!).
In luscious, lyrical language, author Lynn Street pulls readers into the acorn-caching behavior of blue jays who hide their treasure – like pirates! “With their beaks, the jays tap, tap, tap the acorns into soft ground…” she writes. The jays have to move fast, because there’s competition. Squirrels, turkeys, mice, chipmunks, deer … they are gathering up acorns too.
What I like about this book: I mentioned the language. Here’s what I mean: “Back and forth— flashes of sapphire in the sun— blue white, blue white.” Even without an illustration you can picture this blue jay flapping across the sky. I like that Lynn takes us through an entire year: winter when jays dig up the acorns to eat, spring when they feed their nestlings bugs (because acorns are too big for babies…), and fall, when the young jays join the “blue crew” and help their parents collect acorns for the winter. I like the back matter, too! More information about oak trees and jays, and how human interaction has changed the nature of oak forests. There’s also a great list of books for further reading and some websites to visit.
Me: What cool insights have you gained from the jays visiting your backyard? (ours are raucous thieves!)
Lynn: I watched blue jays in my backyard as they interacted with a pin oak just over the fence. From a second story window, I was able to see into the oak’s canopy as jays pried acorns from the tree. Over several fall seasons, I spotted more and more of this acorn gathering in real time.
I noticed, too, where the peanuts from my bird feeder were being hidden. One jay buried a peanut under leaf litter. Another time I spotted a jay leaving a peanut in the rain gutter of my neighbor’s house. I also watched a blue jay pull an acorn out from between flagstones on my patio.
Me: Jays are related to crows, and crows are pretty smart birds. How do jays exhibit their corvid intelligence?
Lynn: Blue jays are part of the corvid family, which includes crows, magpies, nutcrackers, and ravens. Blue jays are very intelligent. They have an amazing spatial memory, which helps them locate thousands of buried acorns. The blue jay that dug up an acorn from my patio knew exactly where it was hidden. It landed, plucked it out, and was flying again a few seconds later.
Blue jays are also great mimics. Their calls can sound like a hawk, or a squeaky gate. The hawk call may alert other jays to predators nearby or trick other birds into thinking a hawk is present. I hear the hawk call often, and the jays always fool me. I look outside when I hear it, but each time it’s a blue jay perching in a nearby tree. Only one time was it a hawk circling high above my street.
In captivity—but not in the wild—blue jays have been observed using tools to rake food into their cages.
The black markings on their faces and throats (called a bridle or necklace) vary and may help the jays to tell each other apart. Do you think you can tell the blue jays at your feeder apart?

Beyond the Books:
Watch some blue jays this fall. Draw a picture of what your jays look like – and make sure to note the markings on their faces and throats.
This one comes from Lynn: Watch your jay’s behavior. Is the bird eating? Is it hiding food or plucking an already buried acorn out of the ground? Blue jays move quickly, so pay close attention!

Do you have oak trees in your neighborhood? If so, get to know them. Draw a map of where the oak trees are growing.
In the spring, look for oak sprouts. You might find one in your yard or neighbor’s garden. If it’s “in the way” ask if you can dig it up. Then put it in a pot and watch it grow,
