Estimating The Size Of Georgia's Resident Canada Goose Population, Gregory D. Balkcom
Estimating The Size Of Georgia's Resident Canada Goose Population, Gregory D. Balkcom
Georgia Journal of Science
Canada geese (Branta canadensis) are an important waterfowl species in Georgia, and are hunted across the state. To meet management objectives, managers need to understand the impacts of hunting regulations on the population of interest. Therefore, reliable population estimates are necessary. Population size can be estimated by various methods, including aerial surveys, ground surveys, or population indices such as the Lincoln Estimator. I used annual estimates of resident Canada goose harvest in Georgia from the U.S. Fish and Wildlife Service’s Harvest Information Program along with banding and recovery data from the Bird Banding Laboratory in a bias-adjusted version …

Populations of temperate-nesting Canada geese (Branta canadensis) have increased in Nebraska, USA, resulting in an increased number of nuisance and damage complaints. September hunting seasons were initiated in southeastern Nebraska in 2004 to reduce populations of Canada geese. We analyzed band recoveries from Canada geese banded in southeastern Nebraska during their hatch-year (HY) or after-hatch-year (AHY) to determine whether September hunting seasons affected survival, harvest, and recovery rates. Survival analyses revealed that HY geese had higher survival than AHY geese (SAHY = 0.696, 95% CI = 0.679–0.713; SHY = 0.896, 95% CI = 0.786–0.953) and September seasons did …
Summary Of Sandhill Crane Sport Harvest In Canada 1975-2006, Adrianna C. Araya, Kammie L. Kruse, Keith D. Warner
Summary Of Sandhill Crane Sport Harvest In Canada 1975-2006, Adrianna C. Araya, Kammie L. Kruse, Keith D. Warner
Proceedings of the North American Crane Workshop
Knowledge of harvest in all areas where the mid-continent population (MCP) of sandhill cranes (Grus canadensis) occurs is critical to managing the population in a sustainable manner. The harvest of MCP in the U.S. has been well documented; however, the harvest in Canada has received less attention. The Canadian Wildlife Service initiated a National Harvest Survey program in 1967, but all sampling variables were not directly comparable until 1975. In this paper, we summarize crane harvest in Canada during the 1975-2006 hunting seasons for Saskatchewan and Manitoba, the 2 provinces with significant sport hunting harvest of sandhill cranes. …

Summary Of Sandhill Crane Hunting Seasons In Kansas 1993-2007, David E. Sharp, Helen M. Hands, James A. Dubovsky, John E. Cornely
Proceedings of the North American Crane Workshop
The mid-continent population of sandhill cranes (Grus canadensis) is the largest population of cranes in North America. Hunting seasons for sandhill cranes were closed in 1916 and gradually resumed in Mexico (1940), the United States (1961), and Canada (1964). As knowledge of the biology of cranes and experience with hunting seasons increased, areas in which hunting was permitted expanded, and by 1992 all but 2 states (Nebraska and Kansas) in the U.S. portion of the Central Flyway conducted sport hunting seasons for this population. In 1993 Kansas resumed hunting and initial seasons were limited to specified geographic areas of …
Population Status , Hunting Regulations , And Harvests Of The Rocky Mountain Population Of Greater Sandhill Cranes, 1981–2005, Kammie L. Kruse, David E. Sharp, James A. Dubovsky
Population Status , Hunting Regulations , And Harvests Of The Rocky Mountain Population Of Greater Sandhill Cranes, 1981–2005, Kammie L. Kruse, David E. Sharp, James A. Dubovsky
Proceedings of the North American Crane Workshop
The Rocky Mountain Population (RMP) of greater sandhill cranes (Grus canadensis tabida) was not hunted in the U.S. from 1916 until 1981, when Arizona initiated the first modern-day season. Hunting programs in the U.S. were subsequently expanded to 6 states for the RMP and have been guided by a cooperative flyway management plan, including a harvest strategy, which has been periodically updated and endorsed by the Central and Pacific Flyway Councils. From a management perspective, 3 population parameters have been identified to monitor the status and health of this population: harvest, recruitment, and population size. The number of …
Hunting Success For Mid-Continent Sandhill Cranes In The Central Flyway: Comparing Current And Historic Results, James A. Dubovsky, Adrianna C. Araya
Hunting Success For Mid-Continent Sandhill Cranes In The Central Flyway: Comparing Current And Historic Results, James A. Dubovsky, Adrianna C. Araya
Proceedings of the North American Crane Workshop
Sport hunting for the Mid-continent population of sandhill cranes (Grus canadensis) in the United States resumed in New Mexico in 1961 after a 45-year moratorium. Interest in crane hunting continued to increase and by 1975, 8 states were participating in sandhill crane hunting. Currently, hunting seasons have been established in all Central Flyway states except Nebraska. Efforts to collect information on the annual harvest of sandhill cranes began in 1975 when hunters were required to obtain federal sandhill crane hunting permits. The permits included a hunting diary whereby hunters were asked to record information about their daily hunting …
Models For The Adaptive Harvest Management Of Rocky Mountain Sandhill Cranes: Problems And Potential, William L. Kendall, Roderick C. Drewien
Models For The Adaptive Harvest Management Of Rocky Mountain Sandhill Cranes: Problems And Potential, William L. Kendall, Roderick C. Drewien
Proceedings of the North American Crane Workshop
The migratory Rocky Mountain Population (RMP) of the greater sandhill crane (Grus canadensis tabida) breeds primarily in river valleys, marshes, and meadows of western Montana and Wyoming, southeastern Idaho, northern Utah, and northwestern Colorado. The RMP winters primarily in the Middle Rio Grande Valley of New Mexico, with smaller concentrations in the southwestern parts of that state, southeastern Arizona, and the northern highlands of Mexico. The San Luis Valley of Colorado is used as a stopover in both the spring and fall migrations. The RMP has been hunted on a permit basis since 1981, and currently these cranes …
Sandhill Crane Hunts In The Rio Grande Valley And Southwest New Mexico, C. Gregory Schmitt, Barry Hale
Sandhill Crane Hunts In The Rio Grande Valley And Southwest New Mexico, C. Gregory Schmitt, Barry Hale
Proceedings of the North American Crane Workshop
Annual limited permit hunting seasons for sandhill cranes (Grus canadensis) were initiated in southwestern New Mexico (SWNM) in 1982 and in the middle Rio Grande Valley (MRGV) in 1986. Within the MRGV and SWNM are wintering areas for 3 migratory subspecies, including the lesser sandhill crane (G. c. canadensis) (lessers). Canadian sandhill crane (G. c. rowani) (Canadians), and greater sandhill crane (G. c. tabida) (greaters). We summarized annual season dates, bag limits, requirements for permits, procedures for examination of crane specimens at check stations, number of hunters, estimated harvest, mean harvest per …
Summary Of Sandhill Crane Hunting Seasons In North Dakota, 1968-94, David E. Sharp, John E. Cornely
Summary Of Sandhill Crane Hunting Seasons In North Dakota, 1968-94, David E. Sharp, John E. Cornely
Proceedings of the North American Crane Workshop
The migratory Mid-continent Population (MCP), containing 3 subspecies, is the most numerous of all sandhill crane (Grus canadensis) populations. During fall the MCP uses major staging areas in the Canadian prairie provinces and northcentral United States. In North Dakota, sport hunting of the MCP resumed in 1968, after being closed during 1916-67. The resumption and expansion of crane hunting in North Dakota during 1968-94 followed a gradual panern of implementation. Subspecies considerations, the presence of whooping cranes (G. americana), crop depredation complaints. and public reaction influenced the geographic and temporal expansion of seasons. Harvests gradually increased …
