American woodcock winter distribution and fidelity to wintering areas American woodcock winter distribution and fidelity to wintering areas
We examined winter distribution and fidelity to wintering areas for the American Woodcock (Scolopax minor), which exhibits reversed, sexual size dimorphism. Band-recovery data revealed no difference in winter distributions of different age/sex classes for woodcock from the same breeding ares. Similarly, band recoveries from woodcock banded on wintering grounds revealed no difference in...

Industrial strength herons: The Black-crowns of Baltimore Industrial strength herons: The Black-crowns of Baltimore
The largest night-heron colony in Maryland is located at the foot of the Key Bridge in Dundalk, Maryland, in an industrial area. Foraging herons were followed from the colony during May-July, . Most birds followed landed near industrial/urban sites. Availability of perches and lights (at night) may serve to enhance the heron's prey capture success.

Modeling and the management of migratory birds Modeling and the management of migratory birds
Mathematical modeling of migratory bird populations is reviewed in the context of migratory bird management. We focus on dynamic models of waterfowl, since most management-oriented migratory bird models concern waterfowl species. We describe the management context for these modeling efforts, with a focus on large-scale operational data collection programs and on processes by which...

Taxonomic status of the rufous-bellied chachalaca (Ortalis wagleri) Taxonomic status of the rufous-bellied chachalaca (Ortalis wagleri)
The Rufous-bellied Chachalaca, Ortalis wagleri, of northwestern Mexico was merged with the morphologically different West Mexican Chachalaca, Ortalis poliocephala, on the basis of hybrids taken in the vicinity of Puerto Vallarta, Jalisco (Moore and Medina 1957). Eight specimens from that vicinity vary in appearance chronologically, from an individual similar to wagleri in 1892 through...

Paraquat Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Paraquat Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Paraquat (1,1`dimethyl4,4`bipyridinium) are broad-spectrum contact plant killers and herbage desiccants that were introduced commercially during the past 25 years. Today, they rank among the most widely used herbicides globally and are frequently used in combination with other herbicides. The recommended paraquat field application rates for terrestrial weed control usually range between...

Chlordane Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Chlordane Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Technical chlordane is an organochlorine compound first introduced into the United States in 1947 in a variety of formulations for use as a broad-spectrum pesticide. By 1974, about 9.5 million kilograms of chlordane were produced annually. Concern over the potential carcinogenicity of chlordane has led to sharply curtailed production. Since 1983, chlordane use in the United States has...

Boron Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Boron Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Ecological and toxicological aspects of boron (B) in the environment are reviewed, with emphasis on natural resources. Subtopics covered include environmental chemistry, background concentrations, effects, and current recommendations for the protection of living resources. Boron is not now considered essential in mammalian nutrition, although low dietary levels protect against fluorosis...
