Where does a swallow nest?

A swallow builds its nest inside farm buildings and on ledges in old chimneys. The nest is made of mud, straw and saliva, with feathers and wool to line the inside. It takes a pair of swallows up to several weeks to make the saucer-shaped nest in the rafters of a barn. Swallows starts arriving in Europe at the end of March, a little earlier than their close relatives, the house martins.

We studied the diets of nesting Swallow-tailed Kites (Elanoides forficatus) at eight nests in 1988–1989 in southern Florida, where the species reaches its greatest abundance in the United States. Males fed females during the incubation stage an average of 2.1 ± 0.8 times per day. The adults averaged 10.9 ± 4.5 deliveries daily during the nestling stage, and 10.3 ± 12.5 deliveries to young daily following nest departure.

Edible Bird’s nest?? I can’t imagine how one can transform twigs and grasses into a gourmet food.

The nests in making bird’s nest soups are exclusively those of swiflets, the birds from the family of common swallow. These highly prized nests are built and clung to the ceiling of the caves as high as 70m by the birds mostly of seaweed that is mixed by their own saliva, making the process of harvesting an ordeal and expensive. Swiflets nests are mostly found on cliffs in areas along the Southern Chinese coast and South East Asia .
