As soon as that bird proves the situation to be safe, the rest proceed to the water. Crested Pigeons also has the ability to suck water rather than having to throw its head back to swallow. Crested Pigeons have a diet consisting of mainly small insects, green vegetation, small bulbs, and seeds. These seeds are mostly from herbaceous plants including Acacia trees. However, recently they have been found eating exotic seed crops and introduced weeds as well.
Crested Pigeons tend to breed any time of the year but mostly spring and summer.
Their nest is normally in a platform of twigs located in a tree or a bush. First the male begins his courtship dance by bobbing his head up and down and proceeds as it spreads and raises his tail and half expands its wings. Advertising a low coo he continues next to display his iridescent green feathers, tilting them to shimmer in the sunlight. Once a female is attracted, the male then proceeds to throw the female out of the nest until she returns enough times for the male to finally accept her. At the sign of acceptance, the female hops around dancing, this is a sign that the two are united.
