While checking the bird houses at Yellow Banks County Park this afternoon I found, it seems, a bluebird and chickadee each sharing the same nest. On March 29 there was a nearly completed mossy chickadee nest in this particular bird house. Today, there was a complete bluebird nest on top, with 5 chickadee eggs & 4 bluebird eggs in the bowl. Nothing was out of order. The bluebird nest would have been built & the 9 eggs laid within this 12 day span. How can this be? Do they share this nest? Take turns laying eggs? If the bluebirds built their nest after the chickadees built theirs, would the bluebird have let the chickadee lay 5 eggs before laying her 4? I can't tell in what order the eggs were laid, tho the bluebird eggs are larger, of course, & 3 of them appear to have been laid later. Carl Nollen s.e. Polk County
