I am often outside late at night and I always hear diurnal birds calling. I know why it is though, it's always by street lights so the birds think it's time to start calling when it's clearly not. My question is why is it always the same 2 species a majority of the time? The 2 birds I hear most frequently are Chipping Sparrows and Robins (I heard a Yellow Warbler last Year). I have a feeling it has something to do with these 2 species living in close proximity to the urban sprawl. If anyone else has a theory, please comment.
