Species survive because they adapt. The Gulf Coast is not likely to run out of birds any time soon:
On our first evening here, we dropped into a local supermarket to pick up a few essentials. When we came out, we noticed a flock of small birds hopping from car to car. They were carefully inspecting headlights, radiator grilles, etc. for dead insects and eating all they found. It was very businesslike behavior. Thinking about it, it was entirely logical, of course. Many people drive hundreds of miles to get here, and accumulate lots of dead insects on the front of their vehicles in the process. What better source of food for a hungry bird? I wonder how long it took them to learn to look there?
We’re not exactly a tourist destination here in the Big Breezy, so our major example of bird adaptation can be seen most easily in big box store parking lots: roughly four-and-twenty black birds for every dropped bag of popcorn. Ground Zero might be the Crest Foods store at 23rd and Meridian: not only does it sell a lot of to-go stuff to people who will actually eat it walking back to their cars, but in front of it are a Burger King and an A&W/Long John Silver’s combo.
Then again, we’re not talking picky diners here:
Crows have been reported to eat over 1000 food items, including insects, worms, berries, birds eggs and nestlings, small mammals, bats, fish, snakes, frogs, salamanders, animal dung, grain, nuts, carrion, fried chicken, hamburgers, Chinese food, french fries, and human vomit.
They can be weirdly picky though — an experiment showed crows prefer French fries in a McDonald’s bag over those in a brown paper bag. To top it off, a nestling can eat 100 grasshoppers in 3 hours.
You can’t tell me that a crow can’t recognize the Golden Arches.
