Bald Eagle Nest Site Selection and Nesting Habitat in Maryland

Swainson's Hawk (Buteo swainsoni) nest sites on the Regina plain were compared with randomly selected sites. Various immediate and surrounding habitat variables were examined to determine whether this hawk shows a preference for nesting habitat. Results showed that hawks selected nest sites with significantly less surrounding wheatland and more surrounding grassland, trees, and shrubs than random sites. Nest sites were also farther from buildings and water and closer to larger communities than random sites. These results suggest that this hawk selects nest sites least affected by agriculture.

Nesting Activity

Nest and nidification behaviour of the Spoonbill, Platlea leucorodia (Family- Threskiornithidae) was studied for three seasons during 2003-2005, at Gudavi Bird Sanctuary (GBS), Gudavi village, Sorab, Karnataka. The GBS harbored about 12 thousand birds of various species, of these, only 10-12 pairs of Spoonbills were breeds every year in this place. There were five Spoonbill nests, of which one was old egret nest and the four were newly built by Spoonbills. The clutch size was two to three in each nest (N = 5) and the shape of the egg was oval, white with small brown spots. The nesting activity usually starts in the month of late July and ends during December. The nesting activity, nest site selection, nesting habitat, nesting material, nest size, and nidification of Platalea leucorodia are discussed in this paper.Key words: Spoonbill, Platalea leucorodia, Nest and Nidification, Gudavi Bird Sanctuary,Shimoga.DOI: 10.3126/on.v7i1.2550Our Nature (2009) 7:26-31

Cerulean Warblers

Abstract We examined habitat selection by breeding Cerulean Warblers (Dendroica cerulea) at three spatial scales in eastern Ontario over three years (1997–1999). Territories were characterized by well-spaced large trees, with high canopies and dense foliage cover at heights between 12–18 m. Nesting habitat additionally was characterized by dense foliage cover above 18 m. The results of our nest-patch (0.04 ha circle around nest) and nest-site (0.01 ha circle) analyses indicate that male Cerulean Warblers may take active roles in nest-site selection when selecting territories. We conclude from our nest-patch and nest-site selection analyses that territories likely contain multiple nest patches and sites and that male Cerulean Warblers may defend areas with multiple nest patches or sites, which may attract females to settle with them. Whether or not Cerulean Warbler females use nest-site availability as a mate- or territory-choice cue remains unknown. We also tested the validity of a commonly made assumption that a random sampling of habitat by researchers is representative of the habitat actually available to birds and found that, in our study area, the assumption was invalid. Taken together, our results point toward the need to maintain sizeable stands of mature, deciduous forest to ensure the persistence of Cerulean Warblers in eastern Ontario. Population characteristics such as lower minimum area requirements and a resilience to habitat disturbance may make that an easier job in eastern Ontario than elsewhere in this species' breeding range.

Selection Of

The selection of breeding habitat is of prime importance for individual fitness. Among birds, natural selection should favour the ability to recognize and select habitat suitable for nesting and rearing chicks. This study compares the characteristics of Sabine's Gull, Xema sabini (Sabine, 1819), nest sites with random points across a coastal tundra environment on Southampton Island, Nunavut, Canada. The availability of terrestrial invertebrate prey was also examined among habitats. Sabine's Gull nests were nonrandomly distributed in relation to vegetation, substrate, and proximity to water. Gulls nested within approximately 1 km of the coastline and selected sites with the greatest proportions of moss and standing water (i.e., they nested close to the edge of small freshwater ponds near shore). However, there were no detectable differences in characteristics between successful and unsuccessful nests within preferred habitat. The dynamics of terrestrial invertebrate prey communities varied between years, but the volume of invertebrates in Sabine's Gull nesting habitat was intermediate between the most productive habitats and the least productive habitats in both years. However, nest-site selection in Sabine's Gulls may also be influenced by the availability of aquatic invertebrates (not examined in this study) and their proximity to the marine coastline, where chicks are taken to be reared.
