The Goldman quail pigeon ( Zentrygon goldmani , Syn .: Geotrygon goldmani ) is a ground-dwelling species of pigeon birds, which is one of the quail pigeons . It is a compact, clumsy and short-tailed species with predominantly reddish-brown plumage, which occurs in Central America and in the far north of South America.
The stock situation of the Goldman quail pigeon is given as near threatened . There are two subspecies.
Appearance
The Goldman quail pigeon reaches a body length of 26.5 to 28.5 centimeters, of which 6.5 centimeters are on the tail. The wing length is 14.8 to 15.1 centimeters. The beak is 1.6 inches long. The weight is around 250 grams. There is little gender dimorphism .
male
The forehead is cinnamon-colored and turns into a warm reddish brown on the crown and on the neck. The feathers on the back neck and on the upper coat are slightly stiffened. They are brown-purple. The rest of the top of the body is reddish brown with a warm sheen. The wings are olive brown, the four outer wings are lined with a narrow isabel color. The tail is olive brown.
The chin and throat are white, the face is light brown with small white spots near the neck. The face is bordered by a narrow black stripe of beard. The front neck and chest are gray-brown, the coverts under the tail are more brownish. The flanks are ash brown to dark olive brown. The iris is dark red-orange. The very narrow orbital ring is coral red. The beak and the rein strip are black. The legs and feet are red-purple.
female
The females are similar to the males, but have a darker crown and are a little more brownish on the underside of the body. Overall, the plumage is somewhat more dull than that of the males.
Fledglings
Young birds are generally more dull and brown in color. The forehead and crown are dark brown with red-brown feather edges.
Distribution area
The range of the Goldman quail pigeon is disjoint. It occurs in the extreme northwest of Colombia and in the east of Panama. The habitat are mountain forests at altitudes between 750 and 1500 meters. In Colombia, however, the Goldman quail pigeon has already been observed at an altitude of 90 meters.
A distinction is made between the following two subspecies:
- Z. g. oreas (Wetmore, 1950) - East Panama
- Z. g. goldmani (Nelson, 1912) - nominate form , east of Panama to the extreme northwest of Colombia.
The Goldman quail pigeon is dependent on undisturbed primary forests with dense undergrowth. In regions with selective forest felling, it can only be found where there is a dense secondary forest that borders on primary forest.
Way of life
The Goldman quail pigeon has so far been little researched. It is considered a shy and inconspicuous resident bird, which occurs predominantly solitary or in pairs. The pigeon that lives on the ground seldom flies up and seeks protection in the undergrowth when there is danger on foot. It finds its food in the leaves and undergrowth on the forest floor. It eats seeds and probably also small fruits, insects, larvae and caterpillars. So far nothing is known about the reproductive biology of this species, a young bird was observed in Colombia in October.
