I have often wondered how cowbirds can find their own mates, when they are raised from the egg to the sounds, songs and patterns of other birds. I know a little about imprinting, but I don't know how cowbirds can recognize other cowbirds unless they are genetically "hard wired" to recognize their own kind. If that's the case, how do tnhey do this?
I was surprised and pleased at the end, though I think I went through more eraser than pencil during the process. There's lots more observation when you draw. I think of photographs as a memento -- something captured rather than reproduced.
