Mate Recognition And Fidelity In Captive Sandhill Cranes, Peter W. Shannon

Proceedings of the North American Crane Workshop

Two pairs of greater sandhill cranes (Grus canadensis tabida) were maintained at Audubon Park Zoo in separate but adjacent exhibits. The male of pair #2 was killed and due to medical problems associated with the female of pair #1, male #1 and female #2 were placed together. These birds subsequently bonded but did not nest. Following a 17 month separation, female #1 was moved to an area where she could hear but not see male #1 and female #2 . Almost immediately, male #1 began attempting to move himself closer to female #1 . They were placed together, …

Whooping Crane Habitat Alteration Analysis At Aransas National Wildlife Refuge, Texas, C. Lee Sherrod, Richard Medina

Proceedings of the North American Crane Workshop

Aquatic, wetland, and upland habitat changes were quantified within the approximate critical habitat of the endangered whooping crane (Grus americana) along the Gulf Intracoastal Waterway (GIWW) through Aransas National Wildlife Refuge and San Antonio, Bay, Texas. Study procedures employed comparative analysis of pre-GIWW (1930) and present (1986) aerial photography to provide a basis for the assessment of positive and negative impacts of the construction, operation and maintenance of the GIWW, principally on the whooping crane, but also on biota in general. Thirteen habitat mapping categories were utilized to describe an approximately 1,830 m wide corridor along the GIWW …

Lead Poisoning In A Whooping Crane, S. Bret Synder, Michael J. Richard, John P. Thilsted, Roderick C. Drewien, James C. Lewis

Proceedings of the North American Crane Workshop

The first known incident of lead poisoning in a whooping crane (Grus americana) occurred as the affected bird completed its second migration from Grays Lake National Wildlife Refuge (NWR), Idaho to Bosque del Apache NWR, New Mexico. It fell ill about 4 1/2 weeks after reaching the winter site and was captured. The bird exhibited signs of anorexia and starvation, weakness with drooped wings, greenish watery diarrhea and an unusual gaping of the mouth with abnormal swallowing motions. Blood showed marked polychromasia (>50%) and reticulocytosis (>80%) of RBC's. Serum chemistry values were not diagnostic. A radiograph …

Crane Migration In Northern New Mexico, Dale W. Stahlecker

Proceedings of the North American Crane Workshop

Greater sandhill cranes (Grus canadensis tabida) and foster-reared whooping cranes (G. americana) were monitored on a 345 km migration between their traditional stopover in southcentral Colorado and their winter grounds in central New Mexico during 4 autumns (1984-87) and 1 spring (1985). Autumn sandhill crane counts totaled 17,363 in 1984, 9,317 in 1985, 29,053 in 1986, and 26,552 in 1987. Peak flights of over 7,000 cranes in 1 day were recorded in both 1986 and 1987. More than 50% of the cranes were counted on just 4 days in 1984, 1986 and 1987. At least 27% …

Nesting Of Greater Sandhill Cranes On Seney National Wildlife Refuge, Richard P. Urbanek, Theodore A. Bookhout

Proceedings of the North American Crane Workshop

During 1987, 59 nests of 57 pairs of greater sandhill cranes (Grus canadensis tabida) were located, mainly from the air, on or near the Seney National Wildlife Refuge, Michigan, and 52 nests were ground-checked. Nests were in available palustrine classes without tree canopies. Only 19% were in Sphagnum bogs, in which most nests from other areas of the Upper Peninsula have been found. Cattail (Typha latifolia) marshes, most prevalent in the managed area of the refuge, contabed 44% of the nests, and sedge (Carex spp.) marshes accounted for 37%. Important co-dominant plant species were leatherleaf …

Renesting Of Mississippi Sandhill Cranes In Jackson County, Mississippi 1965–1989, Jacob M. Valentine Jr.

Proceedings of the North American Crane Workshop

Among 118 active nests of Mississippi sandhill cranes (Grus canadensis pulla) in Jackson County, Mississippi, 1%5-1989, 13 were renests. Three chicks from 19 wild and 3 from 3 Patuxent Wildlife Research Center (PWRC) switched eggs hatched in 13 first nests, but 5 died early and 1 after 2 weeks. Ten eggs were dead (infertile or the embryos died) in or at the nest. Two clutches (3 eggs) were destroyed by mammalian predators, 2 eggs were taken for captive propagation, and 1 was pecked and destroyed by the crane pair. Three chicks hatched from 22 wild eggs and 1 …

The Study Of Relatedness And Genetic Diversity In Cranes, George F. Gee, Herbert C. Dessauer, Jonathan Longmire, W. Elwood Briles, Raymond C. Simon

Proceedings of the North American Crane Workshop

The U.S. Fish and Wildlife Service (Service) is responsible for recovery of endangered species in the wild and, when necessary, maintenance in captivity. These programs provide an immediate measure of insurance against extinction. A prerequisite inherent in all of these programs is the preservation of enough genetic diversity to maintain a viable population and to maintain the capacity of the population to respond to change. Measures of genetic diversity examine polymorphic genes that are not influenced by selection pressures. Examples of these techniques and those used to determine relatedness are discussed. Studies of genetic diversity, electrophoresis of blood proteins, relatedness, …

Hawks, Eagles, And Falcons Of North America: Biology And Natural History, Paul A. Johnsgard

Paul Johnsgard Collection

I have tried to present an adequate if far from exhaustive survey of the general biology, ecology, and behavior of all the included species, written so as to be understandable to the interested layman as well as useful to the biologist who might be looking for relevant literature citations or trying to deal with a specific question without resorting to extensive library searches. The larger number of species of North American hawklike birds (31, compared to 19 owl species) has required that I keep the individual species accounts substantially shorter. I have excluded the New World vultures from consideration, primarily …

Helminth Parasites Of Northern Spotted Owls (Strix Occidentalis Caurina) From Oregon, Eric P. Hoberg, G. S. Miller, E. Wallner-Pendleton, O. R. Hedstrom

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminth parasites are reported for the first time from northern spotted owls. Seventyone percent of a sample of Strix occidentalis caurina from western Oregon was infected. Nematodes (Porrocaecum depressum, Capillaria falconis, Microtetrameres sp. and Synhimantus hamatus) were the most prevalent parasites although cestodes (Paruterina rauschi) and acanthocephalans (Centrorhynchus conspectus) were also represented. There was an association between components of this helminth fauna and the diet of spotted owls which is dominated by small rodents. The occurrence of P. rauschi rather than P. candelabraria in this geographic region and host-species may provide additional …

Comparative Analysis Of The Effects Of Visual And Auditory Stimuli On Avian Mobbing Behavior, C. Ray Chandler, Robert K. Rose

Biological Sciences Faculty Publications

Both visual and auditory stimuli elicit avian mobbing behavior, but there is little comparative information on their isolated and additive effects. Using three combinations of two experimental stimuli (mount and tape of an Eastern Screech-Owl, Otus asio) we tested the effects of stimuli on the frequency, intensity, and duration of avian mobbing behavior. Of 169 mount-only trials, only 11 (6.5%) were successful in attracting birds. Tape-only (n = 169) and mount-and-tape (n = 170) were equally successful in attracting birds (approximately 85% of all trials), but mount-and-tape trials were more likely to initiate mobbing behavior. Birds responding …
