[Tweeters] Noctivation in Hummingbirds

[Cliff Drake]

Hi Gang,

Do all hummingbirds noctivate?  (Nocturnal hibernation) I'm only familiar 
with Anna's,

http://research.amnh.org/users/nyneve/hummingbirds.html  for some details, 
the top pic shows one in a very "deep sleep" I swear it was there for an 
hour, I walked right up to it for the pic.
