Como Park Bluebird Trail Update: May 2, 2017

Post contributed by Sharon, volunteer bluebird trail monitor:

The first bluebird eggs of the season.

On the trail today there are two bluebird nests, one with three eggs and the other with one. Tree swallows seem interested in several boxes, but haven’t yet started building any nests. Chickadees started a nest in one box, but may have been stopped from finishing it by tree swallows, even though last week I installed a chickadee entrance hole guard (at 1-1/4” the opening is too small for other birds like tree swallows). Things are off to a slow start this year.
Tree swallows seem to have claimed this box.
