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 […]

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 […]

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 […]

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 […]

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 […]
