Variation in the Costs, Benefits, and Frequency of Nest Reuse by Barn Swallows (hirundo Rustica)
ABSTP•CT.--The frequency of nest reuse and the costs and benefits of this behavior were investigated in a population of Barn Swallows (Hirundo rustica) at Delta Marsh, Manitoba, during 1984-1986. Slightly less than half the clutches were laid in old nests, and this proportion did not change seasonally except in one late year when old nests were preferred by late-nesting pairs. The delay between...
متن کاملColour composition of nest lining feathers affects hatching success of barn swallows, Hirundo rustica (Passeriformes: Hirundinidae)
Many bird species use feathers as lining material, and its functionality has traditionally been linked to nest insulation. However, nest lining feathers may also influence nest detection by predators, differentially affect reproductive investment of mates in a post-mating sexual selection process, and affect the bacterial community of the nest environment. Most of these functions of nest lining...
متن کاملExperimental 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...
