But the home ranges of individuals of both species can overlap and the
species can interbreed. Frequently there are large mixed-species sporting
and/or partying flocks, and occasionally smaller mixed twitching flocks.
Bird-watching hasn't affected me either. Merry Christmas everyone.

I think Australian twitchers should be taxonomically split from British
twitchers, they have more available prey and have to migrate shorter
distances for it. This results in larger flock sizes and greater competition
for prey items. They are clearly more vocal too, must be a separate species.
I used to twitch in UK when I was a teenager, but fortunately it hasn't
