Long-toed Stint (Calidris subminuta) Science Article 2 abstract The mating system of the Long-toed Stint is poorly known. Observations of several broods in western Kamchatka in 1989 suggest a monogamous mating system in which incubation is shared, but with males caring for the brood after hatching Pavel S.

Determinants of lifetime fitness in a cooperative breeder, the long-tailed tit aegithalos caudatus
Long-tailed Tit (aegithalos caudatus) Science Article 1 abstract Long-tailed tits (aegithalos caudatus) are a cooperatively breeding species in which helpers often invest effort in the provisioning of young that are not their own. We quantified the lifetime reproductive success (LRS) and the individual fitness, lambda, of 228 long-tailed tits using 8 years of field data. […]

The effect of helping behaviour on the survival of juvenile and adult long-tailed tits aegithalos caudatus
Long-tailed Tit (aegithalos caudatus) Science Article 2 abstract In the cooperative breeding system of the long-tailed tit aegithalos caudatus failed breeders may become helpers at the nest of another pair to whom they are usually related. The aim of this study was to determine the effect of helping behaviour on the survival of helpers and […]

Evolution of Leks
Long-tailed Hermit (Phaethornis superciliosus) Science Article 2 abstract The most likely reason for males banding in groups known as ‘leks’) for courtship behavior is because it providesan opportunity for females to assess a wide range of males for selection of the best possible traits-and isadvantageous for males because leks increase their chance for encountering females. […]
Systematics and geographic variation in Long-tailed Hermit hummingbirds, the Phaethornis superciliosus-malaris-longirostris species group (trochilidae), with notes on their biogeography.
Long-tailed Hermit (Phaethornis superciliosus) Science Article 1 abstract The degree of relationship between the Variable (Sporophila aurita) and Wing-barred (S. americana) Seedeaters has been debated for over 80 years. The discovery of a zone of hybridization between the former and the Gray Seedeater (S. intermedia), not previously considered to be closely related because of its […]
