Barn swallows are widely recognized for their cup-shaped mud nests. These agile fliers prefer vertical surfaces like buildings, bridges, or cliffs to build their cozy abodes.

Cliff Swallow (Petrochelidon pyrrhonota)

Cliff swallows build remarkable gourd-shaped mud nests, often in colonies attached to cliffs or under overhangs. Their nests showcase their communal behaviors.

House Martin (Delichon urbicum)

House martins, small migratory birds, are renowned for their neat and compact mud nests found on the exterior walls of houses and other structures, especially in rural and suburban areas.

Gray-breasted Martin (Progne chalybea)

Native to parts of South America, gray-breasted martins construct large mud nests in colonies. These nests provide a safe haven for their young in diverse ecosystems.
