The Tree Swallow (Tachycineta bicolor) is a tiny, streamlined songbird well known for catching flying insects in midair with their tiny, flat bill. They are recognized by their long, broad wings, a short, slightly notched or squared tail for making sharp turns when hunting. Both sexes reach a length of 12-15 cm, a wingspan of 30-35 cm (“using apa”, 2017), and a mass of ~20 g (Betini and Norris 2011). Males are recognized by their iridescent bluish-green plumage above, blackish flight feathers, a black lore, and white underparts, while females are duller with more brown in the upperparts with hints of blue-green.
