During the 1980s, the exponential growth of laughing gull (Larus atricilla) colonies, from 15 to about 7600 nests in 1990, in the Jamaica Bay Wildlife Refuge and a correlated increase in the bird-strike rate at nearby John F. Kennedy International Airport (New York City) led to a controversy between wildlife and airport managers over the elimination of the colonies. In this paper, we review data to evaluate if: (1) the colonies have increased the level of risk to the flying public; (2) on-colony population control would reduce the presence of gulls, and subsequently bird strikes, at the airport; …
Determining Differences In The Spatial Distribution Of Forest Structure On The Kaibab Plateau: Implications For Forest Management And The Northern Goshawk, Ryan S. Miller
Other Publications in Wildlife Management
The Kaibab Plateau, in North Central Arizona, has undergone extensive change in the last 100 years due to land management practices such as logging, road building, and fire suppression. The northern goshawk (Accipiter gentilis) has been a center of controversy, due to the potential effects of silvicultural practices on goshawk breeding habitat (Reynolds-1983, Bloom et al 1986, Kennedy 1989, Crocker-Bedford 1990). Current and past research efforts on the Kaibab Plateau have mapped Goshawk nesting territories and temporal change in nesting behavior and success. However, these research efforts have not determined how long-term spatial changes in land-use activities that have influenced …

Usefulness Of Subjective Ovine Milk Scores: I. Associations With Range Ewe Characteristics And Lamb Production, G. D. Snowder, A.D. Knight, L. Dale Van Vleck, C. M. Bromley, T. R. Kellom
Usefulness Of Subjective Ovine Milk Scores: I. Associations With Range Ewe Characteristics And Lamb Production, G. D. Snowder, A.D. Knight, L. Dale Van Vleck, C. M. Bromley, T. R. Kellom
Department of Animal Science: Faculty Publications
Range ewes are commonly evaluated for milking ability by producers to determine the ewe’s ability to rear lamb(s). The U.S. Sheep Experiment Station has subjectively scored (low, average, high) a ewe’s milking ability within 24 h of lambing for many years. The relationship of subjective milk scores with lamb production was investigated using lambing records of Columbia (n = 1,731), Polypay (n = 1,129), Rambouillet (n = 1,704), and Targhee (n = 1,638) ewes. The incidence of high milk scores increased from less than 10% at first parity to 29 to 40% at second and greater parities. At maturity, Columbia …
Increased Egg Conservation-Is It Essential For Recovery Of Whooping Cranes In The Aransasiwood Buffalo Population?, James C. Lewis
Increased Egg Conservation-Is It Essential For Recovery Of Whooping Cranes In The Aransasiwood Buffalo Population?, James C. Lewis
Proceedings of the North American Crane Workshop
The whooping crane (Grus americana) is in a race for survival against adversities (genetic, demographic, and environmental) that are only partially understood. There is increasing evidence of genetic problems (drift, inbreeding, and loss of heterozygosity) in the captive population that likely also exist in the wild Aransas-Wood Buffalo Population (A WP), a consequence of the 1940s population bottleneck. Small populations are vulnerable to extinction through catastrophic events and random changes in productivity or survival. Negative environmental effects faced by whooping cranes include upstream diversion which diminish freshwater (nutrient) inflow into Texas wintering habitats, and expanding human activities along …

Whooping Crane Egg Management: Options And Consequences, David H. Ellis, George F. Gee
Proceedings of the North American Crane Workshop
Eggs to build captive whooping crane (Grus americana) flocks and most eggs for reintroduction experiments have come from second viable eggs in 2-egg clutches in Canada. Four years ago, egg removal ceased. Based on reproductive rates for years when second eggs were removed and for years when eggs were not removed, we project numbers of young fledging in the wild and in captivity for the 2 most likely egg-management strategies. From existing data sets, we find that reproductive performance was, on average, better during the era of routine removal of the second viable eggs than when no manipulation …
Managing Minnesota's Recovered Wolves, L. David Mech
Managing Minnesota's Recovered Wolves, L. David Mech
USGS Northern Prairie Wildlife Research Center
The Minnesota wolf (Canis lupus) population was estimated by the Minnesota Department of Natural Resources at 2,450 during winter 1997-1998 and had increased at an average annual rate of 4.5°% since winter 1988-1989. The population may be removed from the federal endangered species list by 2002, and management would then return to the state. A federal recovery team recommended a population goal of 1,250-1,400 wolves for Minnesota, with none in the agricultural region. A plan approved by the Minnesota legislature, however, continues the protection of wolves, except for pet and livestock depredation control, for at least 5 years …
