Social organization in a nesting population of eastern willets (Catoptrophorus semipalmatus) Social organization in a nesting population of eastern willets (Catoptrophorus semipalmatus)
The breeding ecology of eastern Willets (Catoptrophorus semipalmatus) was studied over a 3-yr period in a salt marsh on the Atlantic coast of Virginia. During the study, 171 adults were color-marked. Willets are strictly monogamous and show strong site and mate fidelity from year to year. Normally a pair bond dissolves only after one member dies or fails to return in the spring. With an...

Ecology of avian brood parasitism at an early interfacing of host and parasite populations Ecology of avian brood parasitism at an early interfacing of host and parasite populations
The shiny cowbird (Molothrus bonariensis), a brood parasite, has recently spread into the Greater Antilles from South America via the Lesser Antilles. This species is a host generalist and upon reaching Puerto Rico exploited avian communities with no history of social parasitism. Forty-two percent of the resident non-raptorial land bird species were parasitized in mangrove habitat study...

Assessment of some important factors affecting the singing-ground survey Assessment of some important factors affecting the singing-ground survey
A brief history of the procedures used to analyze singing-ground survey data is outlined. Some weaknesses associated with the analytical procedures are discussed, and preliminary results of efforts to improve the procedures are presented. The most significant finding to date is that counts made by new observers need not be omitted when calculating an index of the woodcock population...

The influence of diet composition upon growth and development of Sandhill Cranes The influence of diet composition upon growth and development of Sandhill Cranes
Experiments were conducted to evaluate the effect of protein, metabolizable energy, and sulfur amino acid content of five diets upon growth and development of captive Florida Sandhill Crane (Grus canadensis pratensis) and Greater Sandhill Crane (G. c. tabida) chicks raised under controlled conditions. A high protein (32%) diet resulted in faster growth than that obtained when a lower...
