This book was released on 1977 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of the first study of breeding Aleutian Canada geese, the endangered race with a single known breeding population at Buldir Island, Alaska. It was bred on most of the Aleutian Islands, but was reduced to a single breeding site after introduced foxes preyed on these geese on other islands.

Available in PDF, EPUB and Kindle. Book excerpt: The western Canada goose (Branta canadensis moffitti) was divided into a Rocky Mountain population (RMP) and a Pacific population (PP) on the basis of band recovery programs examined in this study and recovery data from other investigators. Habitat information provided a base line for evaluating future changes in nesting, molting, and wintering areas. Topics covered in the discussion of breeding biology are nesting chronology, spring population composition, breeding age, clutch size, nesting success, artificial nesting structures, and gosling survival. Some management recommendations include the refinement and standardization of spring and winter aerial surveys, and more accurate age and sex determinations when geese are banded and color-marked.

Download or read book Population Dynamics and Habitat Selection of Resident Urban Canada Geese Branta Canadensis written by Elizabeth Ray and published by . This book was released on 2011 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Populations of resident Canada geese (Branta canadensis) that nest and reside within the contiguous United States have increased at a rate of 7.9% per year to over 3.5 million over the last few decades. Enlarged population levels have resulted in conflicts between geese and humans, including property damage and human health and safety concerns. Noticeable growth of the population of Canada geese in the Indian Bend Wash area of Scottsdale, AZ has been observed in recent years sparking concern that this population will continue to grow at high rates as seen in other urban areas throughout North America. This study was initiated to determine the current population structure, distribution, and productivity of this population of resident geese. During the 2009 to 2010 post-breeding molt, 255 geese were captured and affixed with neck collars allowing individual identification. I conducted surveys from October 2008 to September 2010 and calculated weekly population estimates from mark recapture survey data using the Lincoln-Peterson method. Productivity was also investigated. Nesting was largely limited to one island within the study area, suggesting geese preferentially nest in insular areas to avoid human disturbance. Despite limited nesting opportunities, there was a significant population increase of 15 to 25% from 2009 to 2010 based on population estimates. Goose movement patterns indicate this population has a high level of site fidelity to nesting and molting areas, as has been found in other studies of resident Canada geese. I suggest that management should be implemented to 1) reduce the current population of resident geese through adult removal and 2) limit future recruitment into the population through control of reproduction and habitat modification.
