To give an update on the Black-capped Chickadees in our backyard, it still appears that the parents have not been able to lure the young ones out of the nesting box. I took this photo of a young one looking out of the bird house. He appears to be checking out how far it is to the ground if he decides to leave the nest.
In other news in our back yard, this photo shows a good comparison of the recently fledged House Finch on the left, with its mom on the right.
This last photo shows a juvenile Spotted Towhee.
