“…Strelke and Dickson (1980) did not find cowbirds >100 m into the woods in Texas, although other studies (Robbins et al 1989, Robinson 1990) have shown deeper penetration into the forest interior. Brood parasitism by cowbirds and nest predation by blue jays and other predators are thought to occur primarily within about 100 m of the forest edge (e.g., Gates andGysel 1978, Temple 1986).…”

During spring of t988 and winter of 1988-89, we sampled songbird populations and habitat characteristics along two belt transects extending across the broad, forested floodplain of the Cache River, Arkansas, USA. Objectives were to compare avian abundance and species richness among floodplain forest zones and to investigate bird species distributions in relation to the wetness gradient. Forest zones differed in structure, flooding regime, and use by birds. The tupelo/baldcypress zone, in particular, provided habitat unlike that in the higher oak-dominated zones and supported a number of bird species that were much less abundant elsewhere. Distributions of chimney swifts (Chaetura pelagica), prothonotary warblers (Protonotaria citrea), and great crested flycatchers (Myiarchus crinitus) were skewed toward wetter sites, whereas summer tanagers (Piranga rubra), red-eyed vireos (Vireo olivaceus), and others were skewed toward drier sites.

“…Th e abundance of terrestrial invertebrates used as food by birds is often lower in small forest fragments (Burke and Nol 1998, Bolger et al 2000, Zanette et al 2000. However, edge habitats comprise proportionally more area in small fragments, and edges are often structurally more complex (Th ompson and Willson 1978), and support higher quantities of nectar, seed, and fruits than habitat interiors (Strelke andDickson 1980, Green 1984). Nectarivores, granivores, and omnivores may thus be less likely to experience food limitation in small habitat fragments than strict insectivores.…”

Spatial patterns of extra‐pair paternity for spotted towheesPipilo maculatusin urban parks

Th e extra-pair (EP) mating system of birds may be infl uenced by food resources, such that nutritionally stressed females are unable to pursue EP fertilizations (constrained female hypothesis; CFH), or that females on poor territories acquire EP fertilizations during extra-territorial forays in search of food (mating opportunity hypothesis; MOH). Edges of urban habitat fragments are sites of apparent high food abundance for spotted towhees Pipilo maculatus , and we used distance to habitat edge in four urban parks in Portland, OR, USA (2004 -2006), to test the CFH and MOH. EP paternity was independent of park identity and year; 44% of nests contained EP young and 26% of all young were EP. As predicted by the CFH, EP paternity was more common in nests of long-tailed (presumably) high quality females. However, independently of tail length, younger females had more EP young than older females, a fi nding consistent with the MOH. Contrary to predictions of both hypotheses, the probability that a nest contained EP young was highest both at the habitat edge and habitat interior while the proportion of young in nests of EP origin (for nests with EP young) was highest at intermediate distances from habitat edge. We propose that high frequency of EP paternity among females in the interior occurred because, as predicted by the MOH, they ranged more widely in search of food and often encountered EP males. High probability of EP paternity near edges was likely unrelated to female quality. Instead, anthropogenic food sources may have attracted individuals to edges and increased encounters between potential EP mates. Simple opportunity seems likely to account for patterns of EP paternity in spotted towhees, suggesting that human altered environments have the potential to substantially aff ect EP mating behavior.

“…Higher bird populations located at the forest edge compared to the community interiors has also been found in several other studies (see Gates and Gysel 1978;McElveen 1979;and Streikle and Dickson 1980). Several theories exist to support such behaviour.…”

Everett, Kim T., and Ken A. Otter. 2004. Presence of cavities in snags retained in forest cutblocks: do management policies promote species retention? Canadian Field-Naturalist 118(3): 354-359.Tree cavities, which are frequently excavated by primary cavity nesters, are typically used by a number of avian and non-avian species and are thus important components in maintaining biodiversity in forest ecosystems. One way to provide these habitat opportunities in harvested areas is through the retention of snags. In this study, we assessed the habitat and snag characteristics that promote cavity excavation, using the presence of cavities to infer activity of primary cavity excavators. Snags retained closer to the forest/cutblock edge contained a greater density of cavities than trees further from edge. However, the proportion of cavities found within cutblocks declined at a more rapid rate with distance from edge than did those in adjacent forested stands. There was also a tendency for cavities to occur more frequently in trees that were at the advanced stages of decay. The results of our study suggest management for snags in harvest areas should include the retention of snags closer to the forest edge combined with incorporating trees showing signs of advanced decay.
