House Sparrow (Passer domesticus) Science Article 7 abstract In this study we relate variation in lifetime reproductive success (LRS) of male and female house sparrows Passer domesticus to morphological characteristics. Our analyses demonstrated no sex-specific difference in the distribution of LRS. The variance in LRS was influenced mainly by variation in individual annual reproductive success, […]

Effects of experimental increase of corticosterone levelson begging behavior, immunity and parental provisioning ratein house sparrows
House Sparrow (Passer domesticus) Science Article 8 abstract Begging is a complex display that is supposed to honestly indicate the need for food of nestlings, and, usually, parents use this informationto adjust their investment in food provisioning. However, the mechanisms that ensure the honesty of begging as an indicator ofneed are still poorly known. Claire […]
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 […]
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 […]
On the taxonomic status and denomination ofthe Iberian Chiffchaffs
Iberian Chiffchaff (Phylloscopus ibericus) Science Article 1 abstract We carried out a Principal Component Analysis on 196 Iberian and Common Chiffchaffsof both sexes (live and collection specimens), characterized by seven variables derived fromwing, tarsus and bill measures. This method, complemented by colour comparison of thetaxa, led us to the following conclusions. (1)Phyllopneuste brehmii, Homeyer, 1871, […]

House Sparrow (Passer domesticus) Science Article 5 abstract Ace Bird Proofing Division is a business that provides structural birdproofing ofcommercial sites in New Zealand. The website provides an extensive list of diseasescarried by bird pests including Campylobacter spp, Eschericia coli 0157, Listeria spp,Salmonella spp, Vibrio cholerae, Cryptococcus neoformans and Histoplasmacapsulatum. However, it is not clear […]
Fitness consequences of hybridization between house sparrows( Passer domesticus) and tree sparrows ( P. montanus)
House Sparrow (Passer domesticus) Science Article 4 abstract Gene transfer may occur following hybridization between closely related species if hybrids are viable and able to breed with individuals of one or both of the parental species. House (Passer domesticus) and tree sparrows (P. montanus) occasionally hybridize and produce viable o.spring. Previously, we concluded that male […]
