Birds feeling neglected

I'm afraid that my backyard friends must think that I've abandoned them. There has been a change in my schedule and as a result my friends don't seem to be around as often. They could be I'm not here during most of the day. I fill their feeders before leaving, unfortunately that is the active time of the morning for the pesky squirrels in my backyard. So they probably don't have food available when they come calling mid morning.
My little squirrel chaser is not going out in the mornings as usual, she is going to be a mother and seems to have become lazy in the mornings. When I let the pup out she races around the house to the squirrel tree looking for the buggers.
