The Swallows are a group of small, agile birds belonging to the family Hirundinidae. They are known for their distinctive forked tails and graceful flight patterns. Swallows are often found in open areas, where they feed on insects while flying. They are migratory birds, traveling long distances between breeding and wintering grounds. These birds typically build their nests from mud and plant materials, often under eaves or cliffs. Swallows are social creatures, often seen in flocks, and they play a vital role in controlling insect populations. Their presence is a sign of changing seasons, as many species return to the same nesting sites each year.
