5 most Beautiful photos of Wire-tailed swallow
The neat half-bowl nests are lined with mud collected in the swallows’ beaks. They are placed on vertical surfaces near water under cliff ledges or more commonly on man-made structures such as buildings and bridges. The clutch is three to four eggs in Africa, up to five in Asia (Turner and Rose). These birds are solitary and territorial nesters, unlike many swallows, which tend to be colonial.
