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.

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, […]

Skeletal Development at the Time of Fledging in House Wrens

House Wren (Troglodytes aedon) Science Article 1 abstract We examined skeletal development at the time of first flight in House Wrens (Troglodytes aedon) as one step in assessing whether calcium availability limits nestling growth in this species. Young wrens begin flying with about 49 mg of calcium in their skeletons, 30% less calcium than is […]

An Incident of Female-Female Aggression in the House Wren

House Wren (Troglodytes aedon) Science Article 5 abstract AIn this paper we describe one example of female-female aggression in the House Wren (Troglodytes aedon). An intruding female usurped the resident female and paired with the resident male. House Wrens are known for committing infanticide as well as puncturing and removing eggs of conspecifics and other […]

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). The […]

NESTING BEHAVIOR OF THE SOUTHERN HOUSE WREN IN SURINAM

House Wren (Troglodytes aedon) Science Article 3 abstract The range of the Southern House Wren (Troglodytes musculus) isvery large, as the species occurs from the tropical coastal zone of eastern Mexico and the Lesser Antilles southward to Argentina, Chile, and the Falkland Islands. In Surinam the bird is well known as the Gado fowroe (God […]
