Unplanned product of a foster-parent program for endangered whooping cranes (Grus americana), a “whoopill” was sired out of a whooper out of a great Sandhill crane (Grus canadensis canadensis). Having failed to produce a single breeding female, biologists have abandoned their efforts to create a viable flock of whooping cranes, whose numbers in the wild have crept from 51 in 1973 to about 165 today. Many think that, rather than struggling to restore a creature so near extinction, efforts should be concentrated on species in the early stages of danger.

A nutria (Myrocastor coypus) shows its chisel-like teeth, which are used for feeding on the roots of marsh plants. The species is found in northern Asia, eastern Africa, Europe, Bolivia, and southern Brazil. This and other nutrias were released from private lands in Louisiana during a 1940 hurricane. The rodents are capable of wetland destruction by denuding patches of marsh which quickly erode.
