Growth and development of the king rail Growth and development of the king rail
Growth and development of the King Rail (Rallus elegans) from hatching to first flight were studied by observations and measurements of captive birds and by observations of natural nests in the field. This is the fourth in a series of reports on the life history of the King Rail (Meanley 1953, 1956, and 1957). Information in this paper is intended to supplement the data of Bent (1925) on...

Calcium, phosphorus and protein levels as factors in the distribution of the pheasant Calcium, phosphorus and protein levels as factors in the distribution of the pheasant
Summary of work on pheasant nutrition conducted since 1949 at the Patuxent Research Refuge. Pheasant chicks fed experimental diets failed to develop normally on protein levels of 15 and 18%. With 22% protein they grew at a reduced rate as compared to those on 28%. Protein level of the reproductive diet was shown to be important; low production of eggs and young resulted from levels below...

Distribution and ecology of whistling swans in the Chesapeake Bay region Distribution and ecology of whistling swans in the Chesapeake Bay region
The Whistling Swan, Olor columbianus, is of particular significance in the Chesapeake Bay region, since major wintering and transient populations occur here regularly, constituting in some years more than half the total population of the species. Some of these concentrations are so large that they attract many bird-watchers, who often travel long distances to see them. Whistling Swans...
