Titmice, and Chickadees, and Finches Too

The house finches came early – right after the chickadees and the titmice (first photo in this post) –to this feeder. Here is a photo of a male and female (photo two and three).
The wren also began coming to this feeder as shown in the last photo.
As this is a small feeder, it sometimes is crowded. Some birds (like the titmice) allow others at this feeder at the same time, other (like the wren) do not. The pecking order of dominance at this feeder is chickadee, titmice, wren, and lastly woodpecker or cardinal.
