The blue-capped kingfisher (Actenoides hombroni), also known as Hombron's kingfisher, is a species of bird in the family Alcedinidae endemic to the Philippines and found only on Mindanao. It is one of the most colorful kingfishers in the country having a dark blue (green for females) cap and wings with rufous spots, a striped rufous belly, white chin and red bill . Its natural habitats are on the upper ranges of tropical moist lowland forest and tropical moist montane forests. It is threatened by habitat loss.
Description and taxonomy
EBird describes the bird as "A spectacular medium-sized kingfisher of foothill and montane forest on Mindanao with a thick red bill, a white throat, a blue rump, and faintly scaled rufous on the underparts and cheek, extending around the back of the neck. The male has a blue crown, blue tail, and blue wings with buff spots. The blue is replaced by green in the female. The male also has an additional blue moustache stripe. Unmistakable. More often seen than heard. Song, given at dawn, consists of a single downslurred whistle with a slightly metallic quality, “wee-ooo,” repeated every few seconds."
These kingfishers exhibit sexual dimorphism in which the males have the eponymous dark blue-cap and dark blue wings. The females on the other hand have aqua-green cap and wings.
This species is a sister species to the Spotted wood kingfisher of Luzon and West Visayas and the Rufous-collared kingfisher of Southeast Asia.
This species is monotypic and now has no subspecies. The birds from East Mindanao were once described as the subspecies burtoni are poorly differentiated.
Ecology and behavior
Feeds on large insects such as grasshoppers, beetles, larvae, snails and also small vertebrates such as frogs and small snakes. It has also been recorded occasionally feeding on fish. This species perches in the lower storeys and flies to the ground to catch its pray. This species is most vocal at dawn.
Breeding season is believed to be January to July. This species has been seen nesting on large termite mounds but no papers and studies have been published on this species.
Habitat and conservation status
Its natural habitats are on the upper ranges of tropical moist lowland forest and tropical moist montane forests having a wide altitude range of 100 -2,400 meters above sea level but with majority of records are above 1,000 masl. They are often found close to streams.
IUCN has assessed this bird as vulnerable with its population estimated at 2,500 to 9,999 mature individuals and thought to still be decreasing. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range. This species appears to show a preference for montane habitats which are most at risk from mining activities especially for chromite and nickel.
It occurs in a few protected areas like Pasonanca Natural Park, Mount Kitanglad National Park, Mount Apo National Park and Mt. Hilong-hilong Watershed but as with most areas in the Philippines protection and enforcement are lax.
