[Tweeters] Correction: Red-footed Booby Behavior Among Heermann's Gulls

[Louise via Tweeters]

Interesting. Are these birds territorial/demanding of personal space away
from the breeding grounds? I believe this is an immature bird who wouldn't
be looking to breed. OR maybe they just pratice some behaviours the way
that young passerines practice singing?
