Habitat: Rock faces, gorges, bridges and tunnels near water.
Appearance: A large swallow that is a resident or summer visitor in the Mediterranean region. It does not occur in Belgium or the Netherlands.
Breeding season: May to October, the nest is built by the pair in one to three weeks on the sunny side in hollows or under overhanging rocks, sometimes also on tall buildings or under bridges. It is bowl-shaped with an opening at the top and is made of mud and lined with soft materials such as feathers and dry grass. 3 to 4 eggs.
Characteristics: Length 14 – 15 cm, wingspan 27 – 32 cm, weight 23 grams, age is not known in available sources.
Food: Flying insects, which the crag martin catches in a feather-light flight in the air currents between the rock faces. During the hunt, the martin manages to catch absolutely everything that the wind carries along.
