Chelidon Boie.* 



Bill short, strong, broad at the gape, gradually compressed on the sides ; the culmen elevated at the 

 base, and slightly curved to the tip ; the nostrils basal, lateral, and rounded. Wings long, with the 

 first quill the longest. Tail moderate and forked. Tarsi longer than the middle toe, and clothed with 

 plumes. Toes long, clothed with plumes, the lateral ones unequal ; the claws moderate and curved. 



The species which forms this division is peculiar to the Old World, and is, like the others of this subfamily, of 

 migratory habits. They are found in the neighbourhood of rivers, or in warm and low moist situations, which best 

 afford them a ready supply of their insect food. Their flight is not rapid, but is more sweeping and buoyant than 

 that of others. When about to migrate they collect in large flocks, which frequently cover for several days the roofs 

 ofjongh buildings. The nest is usually attached to a building or the face of a rock, and is composed of mud, closed 

 6n all sides, and leaving only a small orifice for the passage of the bird ; the interior is lined with straw, hay, and 

 feathers. The eggs are usually five or six in number. '
