Corvid Conversations

The other morning I went out to hang the bird feeders and heard a soft, repetitive call that turned out to be a male goldfinch, molting into his bright yellow and black breeding plumage, high atop a tree in my yard singing to a female high in a tree at the front curb. She, too, was changing into breeding plumage - from winter brown to yellow and green to better blend into the foliage while on her nest. I was eavesdropping on pair bonding.

This morning, I eavesdropped on something very different. This was not pair bonding but a loud conversation, such as what I hear when people are running or bicycling together, to the point of being aggravating. I was on my back porch and was hearing fish crows - eight of them, as it turned out - atop another yard tree. This was not the angry or alarmed cawing of crows when a hawk is in the vicinity. This was just crow talk - a short, nasal caw that sounds like "uh-uh." After a while they flew off to another tree and them eventually left the area.

Crows, of the corvid family, are social creatures. Where you see one, you'll usually see (and hear) more, sometimes in very large flocks. In that way they are similar to their cousins the blue jays, which also travel in noisy family groups.

In my part of the world there are two kinds of crows. There is the American crow and the smaller fish crow. The American is what we think of when we see a "crow" - large, raucous, chasing predators or other, unwanted creatures away, ripping apart garbage bags for what's inside.

As the name implies, the fish crow can be found near water. That is where I saw my first one many years ago. These all-black birds are otherwise hard to differentiate from the American crow unless you hear them or see the two types together - the American is always larger. (Their cousin the raven is larger still.)

That I am seeing and hearing fish crows at all in my neighborhood is a relatively recent, semi-disturbing phenomenon.

All crows are omnivores, meaning they'll eat anything from berries to garbage to dead chipmunks. They are active in the morning when they are hungriest. That is when you will hear them the loudest as they scope out easy to access food sources.

It may not look like it, but jays are related to the corvid
family. (Margo D. Beller)

When I was a kid growing up in coastal Brooklyn, I knew that if I saw gulls whirling in the skies above my house there must be a storm approaching, forcing the birds inland. Now that I live much farther inland, I see gulls all the time. These gulls have learned it is much easier to dive into the open dumpster behind a fast-food place than to fly over the open ocean looking for fish.

The fish crows have learned this, too.

In my area there are several distinct groups of fish crows clustered in the vicinity of food places with lots of garbage going into the dumpsters. The group closest to my house, which centers itself on the local Quik-Chek, sometimes flies along a brook that flows behind the neighbors' houses across the street. These are the ones I hear in the morning, particularly on garbage pickup day. There is another, larger group that hangs out in an area on the edge of town where they can fight the gulls to pick from the dumpsters behind a supermarket on one corner, a fast-food place on another corner and a shopping mall including several food places on a third. (A restaurant is going up on the fourth corner.)

So the crows, like the gulls, are following the garbage because members of the corvid family are very smart and they know where the pickings are easiest and most fruitful. Suburbia provides lots of favorable habitat conditions, including abundant food.

Take the fish crow pictured above. My husband (MH) and I were in Cape May, NJ, one September and I heard a fish crow calling outside our motel room. I looked out the window and there it was, perched on the railing. I opened the door. It did not fly off. In fact, it looked at me with what I would say was a very human look of expectation. MH took its picture. It still didn't fly off. We realized it was sitting on the railing of our balcony room waiting for us to provide its breakfast, the way many other occupants of this room (and perhaps others) had been doing possibly for generations. 

Even though this crow was literally within sight of the Atlantic Ocean, it was waiting for us to serve it. We went back inside and eventually it flew to another railing where maybe the occupant would be more generous.

(There are many reasons I don't feed birds, aside from what I put into feeders in the backyard. You could say I'm selective in what birds I care to feed or that I don't feel the need to show my human mastery over dumb critters, as I see many do. But mainly it is because I know birds like crows will find their own food just fine.) 

Corvids like the fish crow are extremely intelligent. They have large brains capable of memorizing human faces, using tools and solving problems. Young crows will play, swinging from branches or floating in the wind, according to the Cornell Ornithology Lab. They are a species far from threatened by hunting or disease. In fact, their numbers are increasing to the point of them becoming a real pest. Luckily for these crows, they are protected by the Migratory Bird Act even though like the Canada geese - another bird that found suburbia to its taste - they don't exactly migrate in the same way as other types of birds such as warblers.

So what exactly were the fish crows talking about so loudly this morning? They could've been discussing the next place where they could get a meal. They could've been telling another crow I couldn't see to get out of the area. (There was one American crow calling in the distance.) Maybe they were discussing the weather or whether they should go down the shore for a change of pace. Or maybe they were just idly chattering. 

After they left, I started to hear loud human chattering, and that is when I left, too.
