behavior
The gray-capped gloss pigeon is a predominantly ground-dwelling species. It lives predominantly individually or in pairs. Their diet consists of various seeds, berries, small fruits and termites. In their search for food they also look for human settlement areas as well as open areas. Gray-capped gloss pigeons live mostly in pairs. The nest is built in trees or bushes and contains a relatively large amount of plant material compared to other pigeon birds. It has an average diameter of 19 centimeters and is often up to 30 centimeters high. The clutch consists of two eggs. The incubation period is 14 days. The young birds can fledge after twelve to thirteen days.
Keeping in human care
The gray-capped gloss pigeon was shown for the first time in Europe as early as 1794. The first breeding succeeded only in 1880 in Berlin.
The gray-capped gloss pigeon is a species that is well suited for keeping in aviaries. However, it requires a lot of space because it also likes to fly. Today it is often shown in the tropical halls of zoological gardens, as these offer ideal keeping conditions for this species.
