Crowned pigeons differ from other pigeons in having sixteen instead of twelve tail feathers, in the scaling of their legs, in lacking an oil gland and gall bladder, and in possessing a large, fan-shaped crest of erect lacy feathers. The crest is so large and beautiful that these birds have been hunted as much as the birds of paradise.
- The crowned pigeons, belonging to the family Gourinae, are large blue-gray birds with deep maroon below.
- All pigeon and dove species move about in flocks during the day and roost together at night. These birds begin the morning with a chorus of calls before the flock sets out to feed and drink.
