Como Park Bluebird Trail Update: July 25th, 2016

Male bluebird feeds nestlings
Post contributed by Sharon, volunteer bluebird trail monitor:

This week, there are active bluebird nests in five boxes. One has 3 eggs in it; four have a total of 15 bluebirds of various ages in them. Fortunately, the extreme heat of the past week seems not to have harmed any eggs or young. Two more cowbirds fledged from two bluebird nest boxes, but sadly none of their 7 bluebird nestmates survived. The cowbird nestlings either smothered the smaller bluebirds or outcompeted them for food. Six boxes are now empty.
