Ceyx azureus
The Azure Kingfisher, *Ceyx azureus*, is a dazzlingly small and elusive avian jewel, renowned for its iridescent deep cobalt-blue plumage contrasting with rich rufous underparts. Measuring approximately 17-19 cm in length and weighing 28-44 grams, it features a prominent white spot on either side of its neck, a long, dark bill, and bright red feet. Distinctive field marks include its vivid coloration, rapid, low flight over water, and the unique 'whitewater splash' it creates when plunge-divi...
This species primarily inhabits slow-moving freshwater rivers, streams, lakes, and billabongs, often bordered by dense vegetation or rainforest. It can also be found in coastal mangroves and swamps, typically at low to moderate elevations.
The diet consists primarily of small fish, freshwater crustaceans (like prawns and yabbies), aquatic insects (larvae and adults), and tadpoles, captured by plunge-diving from a perch above the water.
Azure Kingfishers are solitary and highly territorial, especially during the breeding season, aggressively defending their prime foraging and nesting sites from conspecifics. They are diurnal hunters, typically spending long periods perched silently on a low branch overlooking the water, often fl...
The Azure Kingfisher is widely distributed across northern and eastern Australia, New Guinea, and parts of eastern Indonesia (e.g., Aru Islands), extending east to the Solomon Islands. It is a largely sedentary species, with no significant migratory patterns, remaining year-round within its estab...
