Effects of food supplementation on female nest attentiveness and incubation mate feeding in two sympatric wren species

Winter Wren (Troglodytes hiemalis) Science Article 2 abstract We examined effects of incubation mate feeding on female incubation behavior and correlates of fitness by providing female Bewick’s Wrens (Thryomanes bewickii) and House Wrens (Troglodytes aedon) with food supplements. Males of these species vary in their rates of feeding; Bewick’s Wrens feed their incubating mates frequently, […]

Evidence for cryptic northern refugiaamong high- and temperate-latitude species in Beringia

Winter Wren (Troglodytes hiemalis) Science Article 3 abstract Stewart and Dalen (2008) argue that only temperate species were locked incryptic northern refugia during Pleistocene glacial cycles, while species presently found athigh latitudes had much wider distributions during glaciations.

SEASONAL MIGRATION AND GENETIC POPULATIONSTRUCTURE IN HOUSE WRENS

House Wren (Troglodytes aedon) Science Article 2 abstract Neotropical migrant birds have undergone significant changes in population size, due in part to alterations in the landscape in their breeding range. Some alterations have resulted in the isolation of areas containing optimal habitat for breeding. Isolation between habitat fragments could reduce gene flow between populations, which […]

GENETIC DIFFERENTIATION AND TAXONOMY INTHE HOUSE WREN SPECIES GROUP

House Wren (Troglodytes aedon) Science Article 4 abstract The current taxonomic status of the Trogliodytes aedon (House Wren) species group was evaluated by examining levels and patterns of isozyme differentiation. Traditionally,three major taxonomic groups of continental House Wrens have been recognized: (1) aedon (Northern House-Wren); (2) brunneicollis (Brown-throated Wren); and (3) musculus (Southern House-Wren).
