Viability Is Associated with Melanin-Based Coloration in the Barn Swallow (Hirundo rustica)
Pigmentation of body surface in animals can have multiple determinants and accomplish diverse functions. Eumelanin and pheomelanin are the main animal pigments, being responsible of yellow, brownish-red and black hues, and have partly common biosynthetic pathways. Many populations of vertebrates show individual variation in melanism, putatively with large heritable component. Genes responsible ...
متن کاملDifferences in begging behaviour between barn swallow, Hirundo rustica, nestlings.
Recent models of parent-offspring communication suggest that nestling begging reliably reflects food requirements, and therefore should increase with nestling need. Need may be affected by short-term variations in hunger, as well as by long-term factors such as relative size, growth rate and body condition. In the present study, the brood sizes of barn swallows were manipulated to create differ...
متن کاملClock gene polymorphism and scheduling of migration: a geolocator study of the barn swallow Hirundo rustica
Circannual rhythms often rely on endogenous seasonal photoperiodic timers involving 'clock' genes, and Clock gene polymorphism has been associated to variation in phenology in some bird species. In the long-distance migratory barn swallow Hirundo rustica, individuals bearing the rare Clock allele with the largest number of C-terminal polyglutamine repeats found in this species (Q8) show a delay...
متن کاملHaematocrit correlates with tail ornament size in three populations of the Barn Swallow (Hirundo rustica)
Advertisement models of sexual selection propose that exaggerated male secondary sexual characters could reliably signal male health and vigour by having the function of ‘handicaps’, i.e. characters that impose a cost to their bearer (Zahavi 1975, 1977; Heywood 1989; Grafen 1990). A commonly cited example of such characters is the ornamental tails of several bird species (Darwin 1871; Fisher 19...
متن کاملBegging and Parental Care in Relation to Offspring Need and Condition in the Barn Swallow (Hirundo rustica).
Parents are selected to maximize their fitness by allocating care among their progeny in relation to the differential reproductive value of offspring. Nestlings have been hypothesized to signal need for parental care reliably through their begging behavior, but offspring condition as reflected by their reproductive value may likewise affect begging and hence provisioning. We assessed the relati...
