Rock swallow nesting and breeding

Breeding season for rocky swallows is from May to July. They arrive at nesting sites at the end of February. Rocky swallows make their nests in dry, sunny places protected from the wind. In the Northern and Eastern Alps, it nests low over a wide valley.

In the Southern and Western Alps, he chooses higher places, but always avoids the northern slopes. Rock swallow colonies are small, usually 2-5 breeding pairs. It is extremely rare to find a cluster of 15 or more bird families.

Birds build a nest under cornices, bridges, rock ledges, and sometimes under the ridge of a building on a busy street in the town. Lumps of clay, tightly adhered to each other, serve as a building material. The entrance is located on the upper side. Feathers, animal hair, horse hair, wood fibers serve as a lining. The female lays 3 - 4 eggs, each in one day.

They are elliptical. The shell color is white with gray and red streaks, sparsely scattered over the surface, forming clusters only at the blunt end. Incubation lasts about 2 weeks. Only the female warms the clutch; the male does not even bring her food. Chick development lasts 24 - 28 days.

Mountain swallows do not form numerous colonies.

For the next two weeks, parents feed their offspring with insects. A second laying is possible under favorable weather conditions. Then the fledglings leave the nest in early October. Young swallows are able to fly 24-25 days after their appearance.

Unkempt nests and droppings constantly falling down, lumps of dirt spoil the appearance of buildings in cities and towns, stain the walls, giving a sloppy look to houses and buildings. In addition, the droppings, dissolving in water during rain, form compounds that corrode the walls of ancient buildings. Therefore, architectural monuments of historical importance are protected with special nets, in the presence of which rocky swallows will not be able to build nests.

The preferred place for the nest of the rocky swallow is the purlins of the roof of the house.

Features of the behavior of the rock swallow

The Rocky Swallow is not a very noisy bird; it does not form large flocks. It catches insects on the fly, making continuous movements in different directions along the surface of the rocks. The rock swallow rarely rises high in the air, and during flight alternates vertical ascents up with a sharp dive down.

This species of birds almost always keeps near the steep slopes of the mountains. When a person appears, she does not show signs of fright, perhaps because she did not come across people who rarely climb rock surfaces. In winter, it endures unfavorable conditions, falling into a daze. With the onset of warmth, it becomes active and constantly feeds in the air.

The clutch of a mountain swallow consists of 3-5 light speckled eggs.
