Fairy & tree martins
Fairy Martins are related to the Tree Martin and are similar to the Welcome Swallow but slightly smaller. Nests are built in clusters, both adult birds build the bottle type mud nests; they share the incubation and care for the young.
The Tree Martin’s nest is usually in the hole in a tree branch mainly in eucalypts and usually located up high in the tree. Nests may also be created in holes or cracks in tree trunks or in cliffs, banks or buildings, and some may build mud nests. Mud is collected from the water’s edge.
Martins are found throughout Australia. Habitat ranges from open grassed areas to forests, especially near wetlands and urban areas where they feed on flying insects in flocks.
