Bird Feeders

canadagry asked:


bird # 1 is standing in the bird feeder.
bird #2 is standing next to the bird feeder, on a post of equal height.

bird #1 gets some food in it’s mouth, flies over to bird #2.
bird #1 regurgitates food into bird #2’s mouth.

(process repeats).

my question is: What are they doing?

baw asked:


I bought this great brass solar bird feeder and hung it on a hook designed for such. It hangs on one side of the yard close to a flower bush. Not one bird has stopped by for lunch. The food I bought is a variety. I can’t even get a crow to stop. WHY?
