The entire season? Doesn't it then make them awfully vulnerable to predation?
Natural selection ought to favor birds who aren't drunk an entire season.
I am well aware also that drugs (including alcohol) are not uncommon for
usage in the animal kingdom. I cannot imagine, really, that natural selection
would allow for animal `druggies' to emerge and maintain in the extremely
competitive and demanding natural world.
