Common crowned pigeons produce a substance known as “crop milk” which they feed to their newly hatched chicks until it’s 3-10 days old. Crop milk’s nutritional content is similar to mammal’s milk.
Common crowned pigeon is the largest species of pigeon in the world. They can grow as big as the size of a turkey which is 74 cm long.
They are considered one of the most beautiful species in the pigeon family. When they mate, the male common crowned pigeons become aggressive in showing off their beautiful feathers to females while bobbing their head. They also make a loud booming noise during their courtship ritual.
