While not rare here in South Florida the Limpkin isn't common either. The Limpkin feeds on snails and it's beak is perfectly suited to it. At the beak's tip the the beak forms a scissor shape that it uses to cut the snail away from the shell. As the Limpkin ages the beak's tip starts to curve to conform to the shell of the snails that it eats. While shooting this one I watched a Purple Gallinule attempt to steal the snail meat once the Limpkin had gotten it free from the shell. Genetically, it is most closely related to the crane family rather than an Ibis as most assume.
