Blue-crowned pigeons are one of the largest species of pigeon in the world. As pigeons, they produce “crop milk” for their young that is gradually supplemented with regurgitated food. Like other pigeons, they can generate suction and drink water without lifting their head.
They forage in groups of two to ten adults, looking for fruits, seeds, grains, and small invertebrates. Their population is declining due to hunting and habitat loss, leading to their classification as “Vulnerable”.
Blue-crowned pigeons are monogamous. Males make a booming call to lure in the females. Males will bring the female nesting material and she will arrange it into a flimsy nest before laying one egg. The female will sit on the egg during the night and the male will incubate it during the day. It takes about 28 days to hatch.
