INDIRECT EFFECTS OF LOW AMPLITUDE ARVICOLINE CYCLES ON DAILY NEST SURVIVAL OF DUNLIN (CALIDRIS ALPINA HUDSONIA) IN A RAPIDLY CHANGING CLIMATE
… risk on alternative prey such as shorebird nests as they share predators. I examined the indirect effects of arvicoline rodent cycles on Dunlin (Calidris alpina hudsonia) reproduction in Churchill, Manitoba. Using 10 years of field data, the study suggests collared lemming (Dicrostonyx …

Reproductive ecology of the island scrub-jay (Aphelocoma insularis)
… 2008 - 2010 I investigated factors influencing nest success, quantified annual fecundity per pair, and documented breeding behavior. Nest predation was the major factor influencing nest success, accounting for 92 percent of documented nest failures. Nests that were initiated earlier in the …

Behavioral ecology of wild turkeys
… season, sensitive to observer presence near the nest site, and as a result our understanding of their incubation behavior is limited to a handful of studies. Lacking this important behavioral information, it remains unclear how incubation behavior among turkey hens influences reproductive …

Demography, Nest Site Selection, and Physiological and Behavioral Responses to Overflights and other Human Activities, of Wilson's Plover (Charadrius wilsonia) at Cape Lookout National Seashore, North Carolina
… decline. I studied Wilson's Plover demography, nest site selection, and physiological and behavioral responses to overflights at Cape Lookout National Seashore, North Carolina, where the National Park Service and U.S. Marine Corps recently lowered the altitude for overflights at tactical speeds. …

Evaluating the Responses of Least Terns, Common Terns, Black Skimmers, and Gull-billed Terns to Military and Civilian Aircraft and to Human Recreation at Cape Lookout National Seashore, North Carolina
… speed military aircraft might generate on nesting colonial waterbirds, and to place any impacts in the context of other human events, 2) a) identify key least tern (Sternula antillarum) demographic drivers, b) evaluate the accuracy of assigning nest fates without using remote cameras, and …

Avian population and community dynamics in response to vegetation restoration on reclaimed mine lands in southwest Virginia
… throughout eastern North America. I evaluated nest-site selection and nest success for on reclaimed mine lands in southwest Virginia during the summers of 2010 and 2011. For this nest-site analysis, I focused on 2 bird species common to reclaimed mine lands in southwest Virginia: field sparrows …

EFFECTS OF SCALE AND HABITAT MANAGEMENT ON GRASSLAND BIRD RESPONSE IN CONSERVATION RESERVE PROGRAM FIELDS IN NORTHWEST ILLINOIS
… species turnover dynamics (Chapter 1) and daily nest survival (Chapter 2). Also, habitat management-related studies often suffer when not accounting for inherent variation between fields, field landscapes, and study year; thus, to disentangle specific effects of management, it is important …

Snakes as predators of bird nests: now and in a warming world
… evolutionary biology. For most species of birds, nest predation is the primary cause of nest failure and snakes have often been implicated as important nest predators. However, in other studies snakes are absent or infrequent predators. Here, I reviewed available nest camera studies from North …

Nesting Ecology Of Red-Headed Woodpeckers (Melanerpes Erythrocephalus) In Central Minnesota
The nesting ecology of Red-headed Woodpeckers (Melanerpes erythrocephalus) has not been well studied anywhere in the species’ range, and the few studies that have addressed nest success have not monitored nests through the entirety of the nesting cycle. The objectives of my study include estimating …

Influence of environmental variation on habitat selection, life history strategies and population dynamics of sympatric ptarmigan in the southern Yukon Territory
… ptarmigan were also more likely to re-nest following failure and had higher daily nest survival, both of which contributed to greater annual productivity compared to rock ptarmigan. Annual adult survival showed the opposite pattern to productivity as rock ptarmigan survival was 24 …

Nesting Success of Grassland Birds in Fragmented and Unfragmented Landscapes of North Central South Dakota
… main objective of this study was to assess the nesting success of grassland birds in relation to habitat patch size and the composition of the surrounding landscape. I evaluated nesting success in moderately grazed native pastures in north central South Dakota within the following categories: 1) …

Breeding Ecology and Productivity of Mallards and Mallard-grey Duck Hybrids in New Zealand
… data from 304 radiomarked female mallards, 491 nests, and 190 broods from 2 study sites in NZ (Southland and Waikato) to answer essential questions about breeding season vital rates and habitat requirements, and to determine factors important in affecting population growth rates. Breeding …

Ecological Factors Associated With Songbird and Small Mammal Predation by Texas Ratsnakes
… avian ecology, predation is the primary cause of nest failure and yet few studies examine predators directly. For my dissertation, I used radio-telemetry to monitor Texas ratsnake (Elaphe obsoleta ) habitat use and behavior to examine predation risk on nests of two endangered bird species breeding …

Effects of black flies on wild turkey reproductive success
… Wild Turkeys (Meleagris gallopavo silvestris), nest success and female survival have been found to have the strongest effects on population growth. Previous studies on Wild Turkeys have established that variables such as weather (e.g., precipitation and temperature), landscape composition (e.g., …

Red-headed Woodpecker Habitat Selection and Breeding Ecology on Fort Drum Military Installation, New York
… and 2013, respectively. I subsequently located nest cavities of breeding pairs to monitor reproductive success and conducted extensive habitat sampling to assess nest-habitat selection.;I used boosted regression trees (BRT) to identify red-headed woodpecker nest-habitat thresholds at multiple …

Population demography of lark buntings: post-fledging survival, fecundity, and breeding decisions
… reproductive productivity and juvenile survival on the breeding grounds are among the possibilities. To assess population declines, direct and reliable estimates of survival, fecundity, and dispersal are required. Consequently, I estimated demographic parameters (i.e., post-fledging …

Reproductive Ecology of Long-billed Curlews Breeding in Grazed Landscapes of Western South Dakota
… main objectives of this study were to estimate nesting success and brood survival and to characterize nesting and brood-rearing habitats of a population of long-billed curlews breeding in western South Dakota. This study was conducted during the spring and summer of 2005 and 2006 on the Triple U …
