Range

Commonly found along the lower Rio Grande River valley in southeasternmost Texas in the United States through Central America to Tierra del Fuego in South America. Reported to expand in Northern direction (Texas).

Habitat

Lakes, rivers, streams, lagoons, and coastal regions. Wide slow-flowing rivers, lowland lakes, marshes, estuaries, brackish coastal lagoons, mangroves, and sometimes open beaches; also sometimes ricefields, reservoirs, canals, water gardens in cities, and Chilean fiords. In Colombia and Bolivia, frequents primarily open habitat along the edges of lakes and streams.

Reproduction

Nests in a horizontal burrow dug in a steep earth or sand bank usually along a river but occasionally in erosion gullies and road cuts well away from water. Tunnel is dug by both sexes and is 2-3 meter deep, 10 cm high with a small chamber at the end. Clutch size is 3-6 eggs, incubated for 212-25 days by both male and female in 24 hour shifts, changing mainly in the morning. Young fledge after 33-38 days.

Feeding habits

Feeds mainly on fish although, when the waters are murky, they sometimes hunt insects, crabs and reptiles. Also reported catching Swallow-tailed Hummingbirds (Eupetomena macroura) on a couple of occasions.

Conservation

This species has a large range, with an estimated global extent of occurrence of 17,000,000 km2. It has a large global population estimated to be 5,000,000-50,000,000 individuals (Rich et al. 2003). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
Ringed Kingfisher status Least Concern

Migration

Mainly sedentary but may fly to distant waterbodies during breeding season. Some post breeding Nothern dispersal recorded.
