Big Flats, NY, USA
This is our first year with a bluebird house. We are in a suburban setting with no Tree Swallows to compete with bluebirds. A pair of Eastern Bluebirds has been nesting each spring at the home across the street so we added the bird house and put a cup feeders with meal worms. After the pair’s first brood fledged, the adults selected our birdhouse for the second brood. Sometime around July 21, I repeatedly saw what I believe is juvenile male perching near to adult, and both visiting nest box as seen it first image. I am sure female was in the box. (There are four chicks.) On August 19, I observed the juvenile male enter box with grasshopper (?) and minute later exit. Note in second image that the wings have male blue but shoulders are still dark. Isn’t this clearly a juvie? Today is 8/20. I observed three drab birds on the next box at the same time. Granted, one could be adult female but at least two are juveniles. I frequently see two of these drab birds at morning feeding frenzy with one entering box, and a second waiting. Are helpers all that rare and we are just lucky?
