Amazon.com description: Product Description: For more than a decade ornithologists have suspected that migrant landbird populations in the United States and Canada are declining. Fragmented forests in the northern breeding grounds and the loss of habitats in tropical wintering zones have been suggested as two major factors in the population declines.
This is the first technical volume to focus exclusively on the question of northern hemispheric migratory landbird declines and their conservation. More than one hundred leading scholars working in the Americas and the Caribbean report on the problems facing these birds and suggest strategies for research and conservation. The book details the basic ecology of many Neotropical migrant landbirds in both temperate and tropical regions. Individual reports--each with a Spanish abstract--probe the reasons for population changes, discuss species behavior during summer and winter months, and gauge the impact of environmental events on landbirds.
This book arose out of a 1989 symposium at Woods Hole, Massachusetts, hosted by the Manomet Bird Observatory--a meeting widely credited for bringing Neotropical migrant landbird conservation to the forefront of attention.
