Welcome Swallow: Hirundo neoxena (other names: Australian Swallow, House Swallow): The swallow builds a cup-shaped mud nest in open sheds, under eaves and anywhere it can attach the nest and have shelter. Seeing any nests brings to mind the work involved for the birds. Their beaks are small and carrying the essential materials to the nest (partners work in the nest building) and then constructing it by the instinct of time and inheritance is one of the often unseen miracles. They are partially migratory and arrive in this area just before Spring to breed. They will often return to the same nest of previous seasons and with the same partner.
