Quick question - do females tuck their heads under the wings to sleep? Both Jewel and Romeo sleep with heads under wings, but it seems that only the males do in the big cage.

I was just going to go out to the big aviary to check on this, but it's midnight. And I am very afraid I won't recognise the budgies with their heads tucked under their wings to tell boy from girl

All mine sleep this way Boys and girls.

yep, same, all my birds will tuck their head in, boy or girl.

I have two girls and they both tuck their heads under.

Pretty never lets me see if he tucks his head, he just poofs up and snuggles down, with the covers over he may tuck, I just can't see it.

All mine sleep with their heads tucked behind their wing.

Budgies (all sexes) and cockatiel put their head under their wings, my lovebrids don't seem to be consistent with it at all.
