We gathered data from 208 American Redstart (Setophaga ruticilla) nests from 1979 to 1985 in southwestern New Brunswick to examine patterns in nest-tree features. Most nests were located in either speckled alder (30.7%) or white birch (22.1%). Nest-site features (nest height, relative nest height, nest access distance) were relatively consistent for those nests located in some tree taxa (alder) but considerable intrataxa variability (cedar, white birch) and several significant intertaxa differences were observed. These differences may reflect each species' branching geometry. Our data were not entirely consistent with existing models of nest-height distribution.

Nest Placement

Territory size, interspecific interactions, foraging behaviour, habitat use, and nest placement were examined in sympatric populations of splendid (Malurus splendens melanotus) and variegated (M. lamberti assimilis) fairy-wrens. Although these species have similar patterns of life history and biology, they utilise different microhabitats within overlapping territories. Splendid fairy-wrens spent more time on the ground and in open areas, whereas variegated fairy-wrens generally preferred higher and more protected locations. The two species exhibited a similar pattern of separation with respect to foraging behaviour, as splendid fairy- wrens mainly foraged on the ground whereas variegated fairy-wrens preferred bushes. They also partitioned nesting habitat, with splendid fairy-wrens building nests in areas with a greater density of trees than variegated fairy-wrens. Further, splendid fairy-wrens built nests in larger shrubs and farther from the edge of these bushes than variegated fairy-wrens. We suggest that these differences in habitat use decrease interspecific competition between the two species.

Nesting Sites

We studied Greater Scaup (Aythya marilla) nest site selection on Grassy Island, New Brunswick, during 1995 and 1996 by describing site selection in relation to habitat characteristics and association with larids using univariate comparisons. We pooled nesting data from both years and found that nesting sites were significantly closer to larid colonies and the edge of the patch of vegetation in which the nests were situated, had less forb canopy cover, more sedge cover, greater overhead concealment and lateral cover at 0–0.25 m, and less ground moisture than random sites. We evaluated Greater Scaup nests delimited as close to or far from larid colonies at 30 m and documented that nests closer to larid colonies were found in shorter vegetation that was closer to the edge of the patch of vegetation with less lateral cover at 0.25–0.5 m, but had greater overhead concealment than nests farther away. Advancements in the ecological understanding of the species, including habitat use patterns and species associations, will increase the likelihood of conservation successes.
