Swallows and bluebirds — like this Western Bluebird —are among the earliest northbound migrants to arrive, heralding spring a month before the equinox. Both species will nest only in cavities, such as old woodpecker holes or man-made nestboxes. But the supply of specialized nest sites is limited, and competition is intense. By arriving early, swallows and bluebirds improve their chances of securing unoccupied cavities.

The Rio Grande Valley hosts one of the most spectacular convergences of birds on earth. Almost 500 species have been documented in this unique place. Many breed and nest along the quiet Laguna’s, palm-fringed Resaca’s and in the lush thorn forests. Each year, birders come here to witness this majestic migratory journey. Birders also come to see bird species they can’t find anyplace else in the country…from the Green Jay and the Buff-bellied Hummingbird to the Great Kiskadee and the Altamira Oriole.
