Black-lored Parrot

The bird is rare and either fully or partly nocturnal, and therefore is poorly described. Its behaviour was reported by the Dutch ornithologist Hendrik Cornelis Siebers (in 1930. The bird predominantly occupies the central, more elevated part of the island of Buru, Indonesia, where it was reported at the settlements of Gunung Tagalago, Wa Temun and Kunturun at elevations of 700–1,100 meters (2,300–3,600 ft), as well on the southern lowlands at Fakal, Ehu and Leksula. There was one observation of these parrots near the Kayeli Bay at the eastern shores of Buru. More recent observations were made off the northern (Waflia) and northwestern (Wamlana) shores. The voice of the black-lored parrot was frequently heard at Kunturun, mostly 1–7 hours after the sunset, where the locals called the bird "kakatua ol'biru", meaning blue-headed parrot. However, it was caught during the day with slingshots in fruit trees suggesting that its activity is not purely nocturnal. Migration is relatively weak and there are only few reports of the parrots flying up and down hill at high altitudes overnight, as judged from their voices. The population density of black-lored parrot is estimated as 1.3–19 birds/km2. These birds apparently favor high-altitude forests which on Buru have areas of 1,789 km2 above 900 m, and 872 km2 above 1,200 m. …
