Father (whom we call Big Daddy) sits on the tree while Mom (whom we call Big Momma) flies to the suet feeder.
Big Momma doesn't fly away. She prepares to feed her Hannah.
Just compare their sizes. Hannah is almost as big as her mother.
I have no idea how long these adults will continue to feed their little girl. They don't fly away from her until she has eaten her fill. Perhaps some birds spoil their little ones just as some parents do. I'm fairly certain that Hannah is eating insects by herself. I have seen her drilling, so perhaps eating at the suet feeder isn't all that important. But I will keep on watching.
