Whooping Crane Egg Management: Options and Consequences

Eggs to build captive whooping crane (Grus americana) flocks and most eggs for reintroduction experiments have come from second viable eggs in 2-egg clutches in Canada. Four years ago, egg removal ceased. Based on reproductive rates for years when second eggs were removed and for years when eggs were not removed, we project numbers of young fledging in the wild and in captivity for the 2 most l...

Whooping crane recruitment enhanced by egg removal

To facilitate recovery through captive breeding and foster-parenting programs of the endangered whooping crane, one of two eggs was removed from 62% of nests in Wood Buffalo National Park during 1967–1996. Egg removals were justified because cranes usually rear a single chick; the other dies to siblicide or predation. Concerns exist that the wild population might have recovered even faster if n...

The Appendicular Myology of the Sandhill Crane, with Comparative Remarks on the Whooping Crane

U NTIL recently, very little had been published on the myology of the cranes. Fisher and Goodman (1955) d escribed in detail the myology of the Whooping Crane (Grus americana) ; they also dissected one Little Brown Crane (G. c. canadensis) . I began a myological study of the Sandhill Crane (G. canadensis tabida) at the suggestion of Dr. L. H. Walkinshaw, whose interest in the biology and taxono...
