Where do Crow and Raven nest?
Crows build their nests in colonies. The male and female partners start building their nest about a month before the breeding season. Their offspring from previous breeding seasons assist them in nest building. The nests are constructed intellectually, with stronger material laid at the bottom for reinforcement. Crows use all kinds of material available around them to construct the nests. They would include twigs, sticks, hay, plant material, aluminium and copper wire, plastic threads, and wood pieces. The nests are usually placed in tall trees and hidden between trunks for improved safety. However, in cities, crows make their nests in inaccessible parts of tall buildings and billboards. The female incubates the eggs for about 18 days, during which time her partner and other offspring feed her. The newly hatched chicks fly when they are about four weeks old but continue to be fed by their parents and siblings for a longer time. The younger ones live with their parents until they start breeding on their own and sometimes even until they are five years old.
Ravens naturally make their nests on treetops or cliffs. In cities, they build their nests on top of roofs, power lines, or billboards. The nest looks like a basket with woven sticks and wires. The male helps the female by fetching the sticks and breaking them into smaller pieces. The eggs are 4.4-5.2 centimeters long and 3.1-3.6 centimeters wide. Both partners take turns to incubate the eggs, which hatch in 20-25 days. The young ones leave the nest when they are five to seven weeks old.
