Ringed Kingfisher
Megaceryle torquata
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. 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. Voice: Ringed kingfishers have louder and lower-pitched calls compared to the belted kingfishers. Captured Juveniles have been heard screaming, giving a klek or kek call. The same call is heard during human intervention or other disturbances. A softer klek is produced by the adult to signal its incubating partner. Its common vocalizations are described as rattles.
