Where do Jackdaw and Owl nest?

Jackdaws are not fussy about their nests. They construct them with sticks and twigs and cover them with moss, hair, or dung. They build the nests in holes and cavities of trees, chimneys, buildings, and rooftops. They may also use nests built by other birds. The eggs are bluish green in color with brown spots. The female incubates them for about 18 days. After hatching, the chicks are dependent on the parents for food. The male and female share the responsibility of feeding them. The chicks fledge when they are 28-35 days old but continue to be reliant on the parents for food for another four weeks. The eggs in the brood hatch asynchronously. When the last egg hatches, the earlier hatched chicks are probably old enough to fledge. Therefore, the parents may abandon the new-borns speculating that they may not survive.

Owls do not build nests. They use holes in trees, quiet places in barns and buildings, caves, natural cavities in river banks, and nests of other birds to lay their eggs. The female Owl starts incubating the eggs when the first one is laid. She lays eggs two to three days apart. Consequently, the eggs do not hatch synchronously. In the nesting season, the female develops additional feathers, called brood patch, on her belly to provide warmth during incubation. The eggs hatch 32 days after incubation. The young ones fledge when they are six to eight weeks old.
