Ringed Kingfisher

Megaceryle torquata is a Neotropical kingfisher that lives in habitats ranging between the US and Mexico. In 1888, the species was first discovered in the US, while the first ringed kingfisher nest was found in 1970. They are commonly seen along the Rio Grande and in water bodies in southern Texas. Their distribution is increasing and expanding northwards.

Measurement. The wings of adult males range between 184.9 and 211.1 mm (7.28 and 8.31 in), with an average of 196.3 mm (7.73 in). Their tails range from 110.0–129.0 mm (4.33–5.08 in), and their bills measure 74.9–94 mm (2.95–3.70 in). Female wings are from 185.0-210.1 mm, and their tails measure 111.5–132.1 mm (4.39–5.20 in) and possess bills measuring 75.9–90.9 mm (2.99–3.58 in). Individuals can weigh between 305 and 341 g (10.8 and 12.0 oz). Such measurements prove that the species do not differ sexually in terms of size.

Identification. Ringed kingfishers have dark-brown irises that are consistent among all age groups. They have straight bills that are longer than their heads, along with curved culmens and tomial serrations. The lower mandible appears to have some yellowish colorations. They possess syndactyl feet with olive-green or yellowish toes and black claws. A large crest appears between the base of their bills and necks. Several individuals have a white collar located around the neck.

Ringed kingfishers are seen in freshwater habitats, tropical and temperate marine shorelines, and several islands, such as Coiba Island. Breeding occurs in aquatic regions with the support of aquatic animals, including fish-populated areas for nesting burrows. Nests can be found farther away from water. Habitats are near waterbodies that include streams, rivers, ponds, lakes, estuaries, and marine habitats. Habitats with clear water and less vegetation are preferred to easily access prey.

Female and male ringed kingfishers incubate their eggs while performing other duties equally. Short foraging breaks are taken during late afternoon since incubation periods are long. Each individual takes turns during the morning. Incubating birds are capable of finding prey by regurgitating their undigested food to attract flies in their burrows.
