Bluebirds! Season 5. Episode 2.

Charles River Peninsula, Needham, MA
Over half the nest boxes at CRP have some kind of nesting going on. The bluebirds, though, seem to be on a pace to lap everyone else.
Eastern Bluebird egg, Box 5
Four eggs already. The tree swallows, meanwhile, have hardly begun. And aren't necessarily making optimal choices.
Tree Swallow nest, Box 15
Full nest in a box full of holes. It's a first year female (brown plumage). Perhaps there's a learning curve.... Meanwhile, the only swallow-sparrow conflict zones are 14 and 16. Tree swallows built over a house sparrow nest in the former; house sparrows over a tree swallow nest in the latter.
American Robin, Charles River Peninsula
In other CRP news: a new robin's nest. Will be watching this one over coming weeks. And I've heard orchard orioles and yellow warblers but not spotted them yet. Waiting anxiously for the migratory explosion this week.
