The shining earth dove ( Geotrygon chrysia ), also called Bahama dove , is a small species of pigeon birds. It only occurs in the Caribbean.

Appearance

The gloss earth pigeon reaches a body length of up to 28 centimeters and is almost the size of a city pigeon. However, it has the typical body shape of earth pigeons and is long-legged and short-tailed. On average, this species of pigeon weighs around 175 grams. The gender dimorphism is only very slightly pronounced.

Males are red-brown with a bronze-green sheen on the front and upper head as well as the neck and back neck. Starting from the base of the beak, a white stripe runs under the eye to the neck. The sides of the neck and the chest are gray-pink. The belly, on the other hand, brightens to a cream tone. The coat and the front back shimmer purple and merge with chestnut brown in the middle of the body. The base of the beak is dark, the tip of the beak reddish. The iris is orange. The eye ring is dull red.

Distribution, habitat and behavior

Bright earth pigeons are found in the Bahamas , Cuba , Hispaniola and Isla de Pinos . They colonize semi-arid forests and shrub biotopes and, at lower altitudes, also moist mountain forests. Bright earth pigeons eat seeds, berries and small invertebrates. The nest is usually built very low in the bushes, in creepers and parasites. It is always in deep shadow. Ground nests also occur. During courtship, the male on the ground lures the female with deep, dark calls. The wings are raised. If the male finds interest in the female, the female runs up, flicking its wings. Both birds trip and then turn in a confined space. The necks are stretched up. The clutch consists of two isabel-colored eggs. The breeding season is 13 days.
