Where do Crow and Seagull 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.

Gulls build their nests in their habitats. It could be at cliffs, coasts, islands, trees, and rooftops as long as they are safe, have food sources nearby, and inaccessible to predators. The nests are built using grass, twigs, and plant material. The eggs take about three weeks to hatch. The young ones are active and fledge when they are five to six weeks old.
