This book was released on 1980 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to investigate the incubation behavior of female Canada geese, as well as to determine the care provided to the eggs during undisturbed incubation. Contradictory or no data exists on several facets of incubation in the Canada goose. The principle reason for this problem is the methodological difficulties involved in trying to obtain data in the field without distubing the nesting females. During the spring of 1979 five Canada goose (Branta canadensis interior) nests were studied on the Hudson Bay Lowlands in northern Manitoba... Data on environmental factors was gathered during this study to determine if they exerted any influence or incubation behavior... Behavioral data indicated that there were five readily distinguishable postures seen while the female was incubating... Nest attendance for the successful nests averaged 95.03% over the entire incubation period... There was a significant effect of stage of incubation on all three egg temperatures, but only a small percentage of observed variance was accounted for by the stage of incubation... The data on egg turning did not support previous research which stated that egg turning was directly related to the weight characteristics of the eggs. The present study showed a great deal of variation in the number of turns of each study egg received... The results indicate that incubating female Canada geese have a high degree of nest attentiveness, provide a relatively stable thermal and physical environment for their eggs, and feed little over the course of incubation. These results suggest that the physical condition of nesting female geese plays an important role in determining nesting success.

Book Synopsis Influence of Sympatric Lesser Snow Geese (Chen Caerulescens Caerulescens) on Reproductive Performance, Behavior, and Food Habits of Canada Geese (Branta Canadensis Interior) on Akimiski Island, Nunavut by : Jeffrey Scott Gleason
Download or read book Influence of Sympatric Lesser Snow Geese (Chen Caerulescens Caerulescens) on Reproductive Performance, Behavior, and Food Habits of Canada Geese (Branta Canadensis Interior) on Akimiski Island, Nunavut written by Jeffrey Scott Gleason and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2003 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on Akimiski Island, Nunavut, indicates declining numbers of nesting Southern James Bay Population (SJBP) Canada Geese (Branta canadensis interior) while increases have been documented for number of breeding Lesser Snow Geese (Chen caerulescens caerulescens). Low direct recovery rates of goslings is suggestive of late-summer mortality which may be limiting recruitment for Canada geese on Akimiski Island. This study was designed specifically to (1) compare Canada Goose reproductive performance, incubation and brood-rearing behavior in areas of allopatry and sympatry and with Lesser Snow Geese, (2) determine if there are differences in diets of Canada Geese in areas of allopatry and sympatry, and (3) determine if there are differences in diets of Canada and Lesser Snow Geese in the area of sympatry. I documented annual variation for all and spatial variation for some reproductive parameters measured. Results of between-area comparisons of reproductive performance tended to suggest that in some years, Canada Geese nesting in the area of sympatry contribute little towards the maintenance of the island segment of this population. During incubation when females were on nests, male behavior varied as a function of year, area, time-of-day, and incubation stage. Overall, male Canada Geese allocated their time primarily to vigilance, feeding, and resting when females were on the nest. Males in the area of allopatry were more vigilant and fed less compared to males in the area of sympatry. When females were on the nest, their behavior varied relative to time-of-day, incubation stage, and temperature. Females in the area of allopatry were more vigilant than females in the area of sympatry, but overall, females on the nest allocated their time primarily to resting and maintenance. Recess behavior of Canada Geese varied relative to sex, incubation stage, and temperature, but not area, though pairs in the area of allopatry tended to spend more time alert and less time feeding compared to pairs in the area of sympatry. During recesses, males allocated their time primarily to vigilance, whereas females allocated nearly equal proportions of time to feeding and maintenance. Overall, brood-rearing behavior varied relative to year, area, time-of-day, sex/age class, days since peak hatch, brood size, brood density, and temperature. Overall, results are indicative of exploitation competition and I suggest that present foraging conditions are insufficient to meet the energetic demands of breeding Canada Geese, as well as breeding and staging Lesser Snow Geese, molt-migrant Giant Canada Geese, and staging Atlantic Brant. Such an energy deficit is particularly detrimental to the growth and development of Canada Goose goslings resulting in locally poor recruitment which presumably will lead to a much depressed breeding population of Canada Geese on Akimiski Island.

Book Synopsis The Rocky Mountain Population of the Western Canada Goose by : William B. Krohn
Download or read book The Rocky Mountain Population of the Western Canada Goose written by William B. Krohn and published by . This book was released on 1980 with total page 104 pages. 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.

Book Synopsis The Great Basin Canada Goose in Southcentral Washington by :
Download or read book The Great Basin Canada Goose in Southcentral Washington written by and published by . This book was released on 1991 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overall, the nesting population of Great Basin Canada geese (Branta canadensis moffitti) on the Hanford Site in southcentral Washington State is doing well and appears to be increasing. The average annual total nests for the period 1981 through 1990 was 215 nests, which is slightly above the average reported for the period 1950 through 1970. The nesting population has shifted its nucleus from upriver islands (1--10) to the lower river islands (11--20) with over 70% of the present-day nesting occurring on Islands 17, 18, 19, 20. The annual percent-successful nests from 1981 through 1990 was 80%. This is above the 71% reported for 1950 to 1970, but is below the 82% reported for 1971 to 1980. Average annual clutch size for 1981 to 1990 was 6.05, which is above the 1971-to-1980 average of 5.6 and the 1950-to-70 average of 5.5. Next desertions for 1981 to 1990 averaged 8%. This rate is well below the 14% reported for 1950 to 1970. Predators were responsible for an annual predation rate of 9% from 1981 to 1990. This is below the 1950-to-1970 annual average predation rate of 14%. Flooding losses to nests were low during the 1980s, except for 1989 and 1990 when 6% and 9% of the total nests, respectively, were destroyed by flooding. 9 refs., 4 figs., 1 tab.
Book Synopsis The Implications of Agriculture in Interior Alaska for Population Dynamics of Canada Geese (branta Canadensis) by : Michael William Eichholz

This book was released on 2001 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Understanding how environmental change affects demography is essential for understanding and managing populations. An anthropogenic change in the environment that has affected wildlife populations is widespread agricultural development. Agriculture has both negatively and positively impacted abundance of species by affecting a variety of vital rates that influence population abundance. In this study, I describe the migration ecology of Canada geese (Branta Canadensis) that nest and stage in Interior Alaska. I also describe how the introduction of agriculture has potentially positively impacted population dynamics of Canada geese by increasing nutrient acquisition, thereby improving their fecundity and survival. Two subspecies of Canada geese used Interior Alaska for staging and at least partially segregated themselves during spring and fall staging. I documented a difference in survival between two age classes of Canada geese, primarily lesser Canada geese (B. c. parvipes), and attributed it to the higher susceptibility to harvest of hatch-year (HY) geese. Estimates of annual survival of Canada geese in this study are among the lowest, and estimates of recovery rates are among the highest, for a migratory population of geese, likely due to behavioral traits and habitat selection that make lesser Canada geese more susceptible to harvest. Survival of after-hatch-year (AHY) female Canada geese was positively associated with the amount of endogenous nutrient reserves females had at the time of banding in fall. An experimental manipulation of nutrient reserves, however, suggested that the association between nutrient reserves and survival results from variation in individual quality (not measured), not a direct relationship between nutrient reserves and survival. Female geese in our study gained fat and minerals, but not protein, during spring staging. Fall staging geese had fat levels greater than or equal to spring staging geese, suggesting fat reserves are important during early fall staging in this population of geese. Although I concluded that the introduction of agriculture has likely increased fecundity and decreased natural mortality in Canada geese that stage and breed in Interior Alaska, I also concluded that mortality due to harvest is sufficient to offset those changes, preventing an increase in the population"--Leaves iii-iv
