The Negros dagger- stinging dove ( Gallicolumba keayi ), also known as the Negro dove , is a very rare species of pigeon birds. It occurs exclusively on the Philippines islands of Negros and Panay . The IUCN classifies the species as critically endangered . The reason for this is that the Negros dagger-stinging pigeon has only a very small distribution area. Continuous clearing has meant that their habitat is highly fragmented and continues to decline. The population is estimated at only 50 to 250 pigeons.

Appearance

The Negros dagger-stinging pigeon reaches a height of 25 centimeters. The crown and the coat are iridescent dark green, the rest of the plumage on the upper side of the body is maroon with a purple sheen. The underside of the body is white. There is a large green and shiny spot on each side of the chest. These spots enclose an elongated, bright orange-red patch on the chest. The lower abdomen is white. The flanks and the under tail-coverts are washed out in orange. The tail feathers are gray with a black end band. The legs are red.

Distribution, habitat and existence

The Negros dagger-stinging pigeon is an endemic species of the Panay and Negros islands. It was observed twice in 1997 in northwest Panay. Panay is a bit more forested than Negros, so there are more opportunities for populations to stay. She also seems to be brooding on Panay. The Negros dagger-stinging pigeon was still a relatively common species on Negros in the 19th century. However, it became very rare in the 1930s. Since the 1980s it has only been observed on Negros in the area of Mount Kanlaon Natural Park , although an expedition lasting several weeks was specifically looking for this species. Occasional other sightings also come from the Northern Negros Natural Park . There appear to be several small populations left in the south of Negros, in the Balinsasayao Twin Lakes Natural Park .

The Negros dagger-stinging dove was a species of the lowlands, at least on Negros. However, all suitable habitats were destroyed here. The Negros dagger-stinging pigeon was only observed at altitudes between 900 and 1,000 meters and it may also be found at altitudes of 1,200 meters above sea level. On Panay she was observed at altitudes of 600 meters.

behavior

So far there are no studies of the behavior of the Negros dagger-stinging pigeon. Observations of captive birds are also lacking. She looks for her food on the ground. Their reproductive biology is unknown.
