The Sangihe Dwarf-Kingfisher has not been recorded since 1997 and it is probably in continuing decline because of habitat loss or already extinct. The species is described in Hume’s “Extinct Birds” published in 2012. Ceyx fallax and C. sangirensis were before 2014 lumped as C. fallax. No recent surveys (f.e Riley 1999, Faustino 2003, Burung […]

Rarest birds of the World: the Flores Hawk-Eagle
This species has an extremely small population that is undergoing a continuing and very rapid decline as a result of habitat clearance, and as a consequence it is listed as Critically Endangered. The Flores Hawk-eagle, Nisaetus floris (formerly Spizaetus floris), is a fairly large, up to 75-79 cm long, raptor in the family Accipitridae. Adults […]
Rarest birds of the World: chatham Island Shag (Phalacrocorax onslowi)
This species occupies a very area on the Chatham Islands, New Zealand. The past 10 years, surveys indicate that the species is in decline. In 2011 the population was estimated to be about 1000 individuals. The breeding colonies suffered much from agricultural activities and feral mammals. These colonial ground breeding species trample their eggs while […]
Rarest birds of the World: The Himalayan Quail (Ophrysia superciliosa)
An interesting writing by Rajiv Kalsi, Rahul Kaul and S Sathyakumar. It was published as part of the ongoing study of Pheasants and allies in India. In my opinion the most complete paper-based search review for the elusive Himalayan Quail. I asked for permission by mail to publish on PoB, but have yet to receive […]
Rarest birds in the World: the Pink-headed Duck
This species has not been seen in the wild, other than some unverified observations, since 1949. Already in the 19th century it was mentioned as rare. It is now considered at the brink of extinction or already extinct because of hunting and habitat loss. In the past decennium it has been much sought after, f.e. […]
Rarest birds of the World: Blue-bearded Helmetcrest
The Blue-bearded Helmet-crest, is one of Nature’s most magnificient creatures. It is a large hummingbird with a long crest and a beard, making it somehow antropomorph.

Rarest birds of the World: Long-billed Tailorbird (Artisornis moreaui)
Artisornis moreaui occurs at two disjuncted locations a 1000 km apart. It always rare in the forests of the East Usambaras in Tanzania (Artisornis moreaui) and Njesi Plateau in northern Mozambique (subspecies sousae). A. sousae was rediscovered in 2003. In spite of intense surveying the species has not been found in the forests between these […]
Rarest birds of the World: White-bellied Heron (Ardea insignis)
This heron has an extremely small and rapidly declining population. The population will further decrease in the next few years. The loss and degradation of lowland forest and wetlands, hunting, egg collecting and disturbance are the mean reasons for this ongoing decline. This is a 127 cm very large, long-necked heron. In fact in the […]

This is a 92-122 cm unmistakable, large, brown-and-white bustard with black crown and wing markings. Males have whitish neck and underparts with narrow black breast-band. Females are smaller, with greyer neck and typically no breast-band. Stuart Baker in his game birds of India, 1921 writes the following account. In ‘ Stray Feathers,’ 1881, Mr. F. […]
Rarest birds of the World: Ridgway’s Hawk (Buteo ridgwayi)
This species is considered Critically Endangered because it has an extremely small and fragmented population, which continues to decline. Only effective protection of Los Haitises National Park and captive breeding and release are likely to save this species from extinction. 36-41 cm. Medium-sized, compact hawk. Above brownish grey, tail dark brown, with 3 faint imperfect […]
