The three pair of Pine Grosbeaks were in the cherry tree again just before 3pm
I noticed that they took turns keeping watch from the tall deciduous tree
It is the same tree our rehab-ed bird flew to after she left the lilac bush one
week ago today.
What's more, each bird flew to the same spot in that tree which she had flown
So that made me suspect that she was a member of this flock before she hit
Originally there were about 20 together, but these last few times only the 6.
Do flocks shift numbers at a certain time of the season or for reasons of food?
We have had plenty of food here all along.
