Herwings

Herwings are a small family of birds in the swallow family, Hirundinidae. They are closely related to swallows and martins, and are found in the Americas. The family consists of two genera, Tachycineta and Pygochelidon, with a total of 15 species. Herwings are known for their distinctive forked tails, which are longer and more pronounced than those of swallows and martins.

Herwings are typically small to medium-sized birds, with a slender body and long wings. They have a short, rounded tail, and their forked tail is usually held upright when they are perched. Their plumage is usually a dull brown or gray, with some species having a white or buff throat or breast. Herwings are insectivorous, feeding on flying insects that they catch in mid-air.

Herwings are found in a variety of habitats, including open woodlands, savannas, and grasslands. They are migratory birds, with most species breeding in the northern parts of their range and wintering in the southern parts. Herwings are not considered threatened, but some species may be vulnerable to habitat loss and other environmental factors.
