Walnut Stories: Part 1

Walnut Stories: Part 1

American Crow

I have a bag of walnuts. I don’t particularly like walnuts, but I got them from our CSA (community-supported agriculture). I remember reading that crows liked walnuts, and there an idea was hatched.

I live high in an apartment building tucked between commercial businesses. From my window, I can see the top of a medical building, which sports a maze of pipes, gravel, and a constant water drip from a cooling unit. It’s the perfect playground for crows. Last summer I watched a pair and their young play in the water drip and use it to wet crusty bread. This summer, a larger and smaller crow have come to play in the pipe maze. I decided to see if the crows would take a liking to locally grown and organic walnuts.

Day 1: Afternoon

Two crows were on the roof of the medical building cawing, unaware of my peering at them. I tossed open my window, which startled the smaller one. The larger one seemed to look at me inquisitively. I tossed one walnut piece onto the roof, which cemented the fear in the smaller crow who immediately ran away. The larger one, however, ran up to the walnut, grabbed it, and proceeded to parade around the roof with the walnut in its mouth until I lost track of it.

I threw another piece to the smaller crow. It eyed the walnut suspiciously for a few moments before deciding it was safe. The crow cautiously slinked towards the walnut, nabbed it, and immediately flew to another spot on the roof to gulp it down. So far, success!

Day 2: Morning

The smaller crow was on the roof by itself. I opened up the window, which did not seem to startle it this time. Instead, it watched me with curious eyes. I threw a walnut piece, and the crow grabbed it, shoved it between its toes, and picked at it for a while.

After a few nibbles, it walked around with the remainder of the walnut in its beak. Then, to my surprise, it stood in front of a brick that was holding up pipes, and the crow placed the walnut remains into a crevice. It then grabbed a few gravel pieces, covered up the walnut, and flew away. It stashed it for later use!

Hints of Fall

Marbled Godwit, Emeryville Marina

Like many birders, I get the summer blues. Breeding season has wrapped up, bird songs have quieted, fledglings are growing up, and frankly it’s too hot for humans and birds alike to be out and about.

But fall is right around the corner. This morning I saw a gaggle of Canada Geese flying silently southward in their V-formation. It reminded me of the flocks of Snow Geese, Ross’ Geese, and Greater White-fronted Geese that winter at the Sacramento NWR. Seeing that V-formation over my apartment was enough to awaken my excitement for the upcoming fall migration season.

Another sign of fall is that shorebird migration has commenced. Already I’m seeing reports of shorebird rarities popping up across the Bay Area. I realized that I’m quite rusty on shorebird ID, so I brushed up my skills by watching a Cornell Bird Academy webinar series on shorebird ID. (Side note: This is an excellent resource if you’re willing to pay $30. It reviews many aspects of shorebird identification, including behavior, habitat, shape, and more.)

One important thing about finding shorebirds is to time your visit with the tides. For example, I like to visit the Emeryville Marina and depending on the tide, I will seek out a different spot. At low tide, a thin mudflat emerges in the harbor, which entices peeps to poke around for goodies. But it’s at high tide that a variety of shorebirds, large and small, collect at the rocks against the trail facing the bay. They are pushed closer to the shore by the rising waters, giving birders a closer look. The same goes with Hayward Shoreline – you want to visit at high tide because the birds are nudged closer to the shore and within viewing range. Take a moment to observe how the tide affects your birds at your favorite shorebird spot!
