Behavior

Behavior ProbingTerritorial males engage in aggressive, ritualistic confrontations that include charging, retreating, and loud calling. Searches visually for snails in clear water, or by jabbing or sweeping with bill. Turns the snail shell opening upward, cuts through the muscle attachment, and pulls out the snail. Extraction takes about 10 to 20 seconds; the shell is rarely broken.Back to top

Conservation

Conservation Low ConcernThere is little information on Limpkin population numbers and trends. The species rates an 11 out of 20 on the Continental Concern Score. The North American Waterbird Conservation Plan lists it as a species of High Concern, but it is not on the 2016 State of North America's Birds Watch List. Limpkin were once abundant in Florida, but were almost eradicated by humans hunting for food. Conversion of wetlands for agriculture, flood control, and development have further contributed to the species' decline in Florida, estimated at about 9.1% per year from 1966 to 1993. Back to top
