Food consumption and retention time in captive whooping cranes (Grus americana)

Zoo Biology, 1997
Food consumption, digesta retention time, and food preference were measured for captive whooping cranes fed pelleted diets. The basal commercial diet was compared to four mixtures containing 70% basal and 30% of one of four important winter foods for the whooping crane: blue crab (Callinectes sapidus), wolfberry fruit (Lycium carolinianum), live oak ...

The effects of captive rearing on the behavior of newly-released whooping cranes (Grus americana)

Predation on Amphibians and Reptiles by Reintroduced Whooping Cranes (Grus americana) in Louisiana

The American Midland Naturalist, 2016
Abstract Predation on reptiles and amphibians by whooping cranes (Grus americanus) is widely reported, but all published data are anecdotal or based on singular observations, and mostly refer to isolated predation events. Some observers consider reptiles and amphibians to only be occasional prey items of whooping cranes. I report observations that show
