One of my blue bird boxes is directly in my line of sight as I sit in my
favorite spot on our rear deck, so I've been observing the occupying couple
closely. All was normal until yesterday, when an interloper male blue bird
showed up and commenced to skirmish with the resident male. The female pays
no attention to these two fools, but continues as best she can to feed the
nestlings. I'm thinking that the chicks are missing out on some
vital nutrition, however, as these two males do very little feeding and
continue their battles.
I've seen adults carrying out white excrement sacs from the box for about a
week now, so I feel that graduation is almost here. It's a little late in
the breeding cycle for a blue bird *menage a' troix*, no?  Is it possible
that the offspring have three parents?
