MALLARD NESTING ECOLOGY IN THE GREAT LAKES
Understanding how habitat features influence vital rates that drive population growth is fundamental for delivery of effective conservation programs. Past decisions in management of Great Lakes mallard (Anas platyrynchos) populations were based largely on paradigms established in the mid-continent …

Nesting Ecology of Grassland Birds in an Agricultural Landscape
… in agricultural settings support successful nesting throughout breeding seasons, and cropland is an important foraging habitat for birds provisioning nestlings and fledglings.

Habitat selection and nesting ecology of translocated Greater Sage-grouse
… affected by anthropogenic features. I examined nesting ecology including the differences in post-release movements between nesting and non-nesting hens and the extent to which nest success is affected by anthropogenic features. I also identified habitat that translocated sage-grouse select in …

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 …

Nesting Ecology of the Ring-necked Pheasant in Eastern South Dakota
Nesting of the ring-necked pheasant (Phasianus colchicus) was studied in 1973 and 1974 and 90 randomly chosen 4.05 – ha plots in the Lake Sinai Township of south-western Brookings County. Nest initiation and hatching peaks over the 2-year period occurred from 1-15 may and 16-30 June, respectively. …

Nesting Ecology of Hawksbill Sea Turtles (Eretmochelys imbricata) on Utila, Honduras
… aimed to increase our understanding of hawksbill nesting ecology in Caribbean Honduras. Characteristics of hawksbill nesting activity and a nesting beach on the island of Utila were elucidated using satellite telemetry, beach profiling, vegetation surveys, beach monitoring, and nest temperature …

Nesting ecology and conservation of shrubland birds in a fragmented urbanized landscape in northeastern Illinois
… highlight the importance of understanding the nesting ecology of shrubland birds. The majority of the literature on shrubland birds has focused on communities in regenerating forest areas following silvicultural practices. Little information exists regarding nesting ecology and success of …

Experimental study of an avian cavity-nesting community: nest webs, nesting ecology, and interspecific interactions
Cavity-nesting communities are structured by the creation of and competition for cavities as nest-sites. Viewing these communities as interconnected webs can help identify species interactions that influence community structure. This study examines cavity-nesting bird community interactions within …

Habitat use, population size, and nesting ecology of conservation priority bird species using restored fields in agricultural landscapes
… related to my third question demonstrated that nesting Bell’s Vireos and Willow Flycatchers selected habitat that increased nest survival, but not number of young fledged from successful nests, in these drastically altered landscapes. Patterns between nest survival and selected habitat features …

Four-Toed Salamander (hemidactylium Scutatum) Nest Site Characteristics In Natural And Constructed Wetlands In Eastern Kentucky
… salamander (<em>Hemidactylium scutatum</em>) nesting ecology and nest-site characteristics and to determine if these differ between natural and constructed wetlands. Another objective was to add to our knowledge of the natural history of the species in Kentucky. Six natural and six constructed …

An Ecological Study of Mourning Doves in a Cold Desert Ecosystem on the Idaho National Engineering Laboratory
… movements around man-made ponds, as well as dove nesting ecology, were studied from 1983 through 1985 on the Idaho National Engineering Laboratory (INEL). Relative dove use was higher (P < 0.01) on some ponds than others, and multiple regression revealed a positive association (R 2 = 0.49) between …

Breeding ecology and related life-history traits of the hoatzin, Opisthocomus hoazin, in a primary rainforest habitat
… is the first detailed study of the hoatzin’s nesting ecology in a rainforest habitat. From 1995-1998 and in 2000 I monitored a hoatzin population which consisted of approximately 700 individuals in an Amazonian rainforest in Ecuador situated in the Cuyabeno Wildlife Reserve (between 0°02’ N, …

Avian breeding ecology in soybean fields: does no-till provide any benefits?
… to regional bird populations. I compared the nesting success and avian communities in tilled and no-till soybean fields. I found significantly higher densities of birds in no-till fields than tilled fields but no differences in avian communities. Of the 114 nests found, 99 were in no-till …

Foraging Ecology And Habitat Selection Of The Western Yellow Robin (Eopsaltria Griseogularis) In A Wandoo Woodland, Western Australia : Conservation Ecology Of A Declining Species
This study examined the foraging ecology and habitat selection of the Western Yellow Robin in Wandoo Woodland at Dryandra Woodland, Western Australia. The foraging ecology component was comprised of an examination of foraging behaviour, perch-use selection and pounce-site characteristics. The …

The role of preen oil and body odour in birds
… and sex differences can be predicted by the nesting ecology of the species (uni- vs biparental incubation, ground vs non-ground nesting) (Chapter 2). These results suggest that preen oil odours could be used to increase olfactory crypsis at the nest, especially in ground-nesting species, but …
