The frog beak liest ( Clytoceyx rex ) is the only species of the genus Clytoceyx a member of the subfamily Halcyoninae of the kingfishers . It occurs exclusively in New Guinea and some offshore islands.
The IUCN classifies the stock situation of this species as harmless ( least concern ).
features
The Froschschnabelliest is an approx. 33 cm tall kingfisher with a mighty short and wide beak. The males are dark brown on top with a dark brown head plate that is sharply set off from the orange neck. The forehead is paler and reddish in color, behind the nostrils with orange feather tips. A narrow but clearly visible orange stripe runs from the eye to the ear. The chin and throat are white, the underside orange to chestnut brown, the tail mostly dark blue-brown.
distribution
Frog beak nests are patchy spread over New Guinea. They settle at altitudes from 0-2,700 m above sea level. They are mainly found in the hills and mountains, locally also in the lowlands in the vicinity of the hills. They live in the interior of the forest.
Systematics
The species was first described by Sharpe in 1880 at the same time as the genus Clytoceyx . It is the only species in the genus. According to Moyle (2006) the genus Clytoceyx is on the one hand related to Dacelo , on the other hand it is related to Melidora together with Dacelo .
There are two subspecies:
- C. r. imperator Oort , 1909
- C. r. rex Sharpe , 1880
This distinction is rejected by Beehler & Pratt (2016), since the size differences between the museum specimens they examined were less than 10%.
behavior
Little is known about the food of the frog-beak nests; it appears to consist of larger earthworms, there is also evidence of insects and their larvae, snakes , lizards and snails . The animals feed on the ground near the support roots of large trees; an area of 20 × 30 cm can be completely turned over to a depth of 8 cm. Almost nothing is known about nests and brood. A nestling found in a market near Wau was said to be one of two from a tree hole.
