Physiological Adaptations for Breeding in Birds is the most current and comprehensive
account of research on avian reproduction. It develops two unique themes: the consideration …

The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Seasonal migration is a taxonomically widespread behaviour that integrates across many
traits. The European blackcap exhibits enormous variation in migration and is renowned for …

This paper shows how our knowledge of the evolution, ecology and conservation of birds
can be improved through the analysis of external morphological traits. After giving a short …

Seasonal migration is intrinsically connected to the balance of survival and reproduction, but
whether migratory behavior influences species' position on the slow-fast continuum of life …

Background The trade-off between current and residual reproductive values is central to life
history theory, although the possible mechanisms underlying this trade-off are largely …

The occurrence of molt during migration, known as “molt-migration,” has increasingly
received attention across many avian taxa since first being described in waterfowl in the …

The functional significance of intra‐and interspecific structural variations in the flight feathers
of birds is poorly understood. Here, a phylogenetic comparative analysis of four structural …

A temporal separation of energetically costly life history events like reproduction and
maintenance of the integumentary system is thought to be promoted by selection to avoid …

A trade‐off between immune system and moulting is predicted in birds, given that both
functions compete for resources. However, it is unclear whether such a trade‐off exists …
