Size of Crow and Stork?

Where do Crow and Stork 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.

Storks build their nests on trees and shrubs that stand in flooded water. They do so to keep predators away from eating the eggs. Both male and female birds participate in the construction of the nest, besides sharing the responsibility to incubate them for about five weeks, after which the eggs hatch. Baby Storks usually fledge 50-65 days after hatching. An interesting fact about parenting in Storks is that the parents sometimes throw some chicks out of the nests so that they can feed the healthy chicks well and support their survival.

How long do Crow and Stork live?

The average lifespan of Crows is 11-15 years in the wild and over 20-30 years in captivity. Again, this is dependent on the species and the location they live in. Crows in North America are known to live over 30 years.
