Managed nest-box programs can significantly increase local populations of Eastern Bluebirds and other cavity-nesting species. Poorly designed boxes, however, may become population sinks rather than source centers. Internal box temperature is an important determinant of box success. Bluebird eggs and nestlings, for example, cannot survive temperatures exceeding 107′ F (41′ C). Several researchers have investigated [...]
Bluebirds are insectivorous during the nesting season, feeding mainly on ground-dwelling insects. Ideal bluebird habitats are open and barren or short-cut/sparsely grassed areas (so they can see their food) with a few trees nearby (for perching). Pesticide and herbicide-free cattle or horse pastures, cemeteries, acreages, abandoned orchards, hike-and-bike trails, prairie coulees, lightly traveled roadsides, abandoned [...]
