Experimental tail shortening in Barn Swallows ( Hirundo rustica ) affects haematocrit
1. Recent studies in Scotland suggest that the outermost tail feathers of Barn Swallows ( Hirundo rustica Linnaeus) may be around 10–12 mm longer than the aerodynamic optimum, with sexual selection for long tails accounting for this extra length. 2. To test this hypothesis, we shortened the outermost tail feathers in male and female Barn Swallows in southern Spain by cutting 1, 11 or 21 mm from...
متن کاملAlbinism and phenotype of barn swallows (Hirundo rustica) from Chernobyl.
The effects of mutation on phenotypic expression are supposed to be mainly deleterious because mutations disrupt the expression of genes that function relatively well under current environmental conditions. Thus, mutations are assumed to give rise to deviant phenotypes that are generally selected against. Radioactive contamination in the Chernobyl region of Ukraine is associated with a signific...

متن کاملA Continent-Wide Migratory Divide in North American Breeding Barn Swallows (Hirundo rustica)
Populations of most North American aerial insectivores have undergone steep population declines over the past 40 years but the relative importance of factors operating on breeding, wintering, or stopover sites remains unknown. We used archival light-level geolocators to track the phenology, movements and winter locations of barn swallows (Hirdundo rustica; n = 27) from populations across North ...
متن کاملAuk, The: Effects of feather lice on flight behavior of male Barn Swallows (Hirundo rustica)
ABSTRACT.-Parasites may affect host behavior in a number of ways, including their locomotory performance. We investigated whether the number of holes produced by the feather louse (Myrsidea rustica) affected flight behavior in adult male Barn Swallows (Hirundo rustica) by video-taping flight performance of individuals during escape and level flight. Percentage of time spent flapping during fora...
