A large brown-and-white bird that resembles a heron but is more closely related to cranes. Specialist on apple snails. Famous wailing nocturnal call.
§ Quick facts
§ Encyclopedia
The limpkin, also called carrao, courlan, and crying bird, is a large wading bird related to rails and cranes, and the only extant species in the family Aramidae. It is found mostly in wetlands in warm parts of the Americas, from Florida to northern Argentina, but has been spotted as far north as Wisconsin and Southern Ontario. It feeds on molluscs, with the diet dominated by apple snails of the genus Pomacea. Its name derives from its seeming limp when it walks.

§ Identification
Field marks. Large brown bird spangled with white spots and streaks, with a long, slightly decurved bill that is gapped and twisted at the tip for handling snails; long gray legs.
Similar species. Immature night-herons and the female-type bitterns are stockier; the Limpkin's spotted brown plumage, long bill, and snail-eating habits are distinctive.
Voice. A loud, wailing, banshee-like scream 'kreee-ow', most often given at night — an unforgettable swamp sound.
§ Diet & behavior
Diet. Omnivorous: aquatic plants, insects, small invertebrates.
Behavior. A unique wading bird (the only member of its family) of southern wetlands that feeds almost entirely on apple snails and freshwater mussels, extracting them with a specialized bill.
§ Range
Florida (expanding north and west)
§ Habitat
Freshwater marshes, swamps, ponds
§ Threats
Loss of apple snail populations due to wetland drainage and water quality.
§ Conservation status
According to the IUCN Red List, the limpkin is currently classified as Least Concern.
§ What helps
Support Florida wetland restoration. Don't introduce invasive apple snails (negative effects on water quality).
