Book Synopsis Breeding Distribution and Population Trends of the Great Blue Heron in Quebec, 1977-2001 by : Jean-Luc DesGranges
Download or read book Breeding Distribution and Population Trends of the Great Blue Heron in Quebec, 1977-2001 written by Jean-Luc DesGranges and published by . This book was released on 2006 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regular surveys of Great Blue Heron (Ardea herodias) colonies in Quebec, conducted between 1977 and 2001, resulted in the discovery of 705 colonies, mostly in the western part of the province. While single breeding pairs were occasionally found (9% of Quebec "heronries"), the colonies were generally composed of fewer than 16 breeding pairs, with sometimes over 50 (18 known colonies), as was the case on several islands in the St. Lawrence River. Close to one-third (1919 of the 6481 active nests) of the Quebec Great Blue Heron population was associated with heronries in the St. Lawrence system. Half of the St. Lawrence heronries that were active during two adjacent survey periods (1975-1983 and 1984-1990, or 1984-1990 and 1991-2001) increased in size between periods, while one-third of the colonies decreased in size. One-sixth of the colonies remained the same size during the study period. Great Blue Herons periodically abandon their colonies and settle elsewhere. Our data show that 50% of known Quebec colonies (n = 377 colonies visited more than once) were abandoned after being discovered as active colonies, and, on average, all nests in colonies that are abandoned disappear 7 years after discovery of the colony. On the basis of thorough inventories conducted on the St. Lawrence, we found that all nest platforms in 14 of the 70 colony sites had disappeared in less than 25 years. Since 1977, when regular surveys began, 50-90% of breeding attempts have been successful, yielding an average of over 2.2 chicks per pair. This productivity rate suggests that the Quebec population of Great Blue Herons may be increasing and may explain the recent expansion in its range. Following our 25 years of investigation on the Great Blue Heron in the province, we estimate the current late-summer Great Blue Heron population of Quebec at some 27 000 individuals (6500 pairs producing 2.2 young per pair per year).--Publisher's description.

Book Synopsis Seabirds and Colonial Waterbirds of the Magdalen Islands by : Jean-François Rail
Download or read book Seabirds and Colonial Waterbirds of the Magdalen Islands written by Jean-François Rail and published by . This book was released on 2009 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This survey of breeding seabirds in 2007 updates the work done by Mousseau et al. (1976), Bourque and Richard (1992), and by the Canadian Wildlife Service (CWS) in 2000-2002, and was a collaborative effort between the CWS and Parks Canada. During an aerial survey that took place on June 9, photographs were taken of breeding colonies that were inaccessible or difficult to census by boat. The remainder of the colonies were visited either by boat or by foot, between June 8 and 22. The size of all colonies of breeding seabirds, plus the Great Blue Heron, were estimated, with the exception of the Northern Gannet which is censused during a specific survey every five years (next due in 2009). Census methods that were used are provided in detail for each site and species. For each species, the current status of the breeding population is discussed and comparisons are made with previous surveys, as well as with historical data, to determine local population trends"--Abstract, p. iii.

This book was released on 2002 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report uses information from surveys of waterfowl hunting activity, based on sampling frames provided by sales of Migratory Game Bird Hunting Permits in Canada and of Duck Stamps in the United States, to track recent changes in hunter activity & success. Demographic data collected by Statistics Canada & the US Bureau of the Census are then used to relate waterfowl hunting to the composition of the human populations of the two countries and to other forms of recreation based on an interest in wildlife.
