White Ibis

White Ibis inhabit coastal areas of the southeastern United States, Mexico and Central and South America. The birds inhabit both estuarine and freshwater swamps. These ibis shift their roosting and colony sites in response to water availability and to concentrations of crustaceans and small fish. Curiously young birds do not survive when fed crustaceans from salty water. Therefore, White Ibis depend on freshwater breeding sites (Heath et al. 2009). 

This aversion to brackish water crustaceans probably does not affect these White Ibis that Erika and I found on 22 February 2014 at Estero Llano Grande State Park. I have previously posted notes on this species.
