This paper advances an hypothesis that the primary adaptive driver of seasonal migration is
maintenance of site fidelity to familiar breeding locations. We argue that seasonal migration …

We approach the problem of the evolution of bird migration by asking whether migration
evolves towards new breeding areas or towards survival areas in the non-breeding season …

Modern attempts to produce biogeographic maps focus on the distribution of species, and
the maps are typically drawn without phylogenetic considerations. Here, we generate a …

Night migratory songbirds can use stars, sun, geomagnetic field, and polarized light for
orientation when tested in captivity. We studied the interaction of magnetic, stellar, and …

The phylogeny of the thrushes (Aves: Turdus) has been difficult to reconstruct due to short
internal branches and lack of node support for certain parts of the tree. Reconstructing the …

One of the characteristics of avian migration is its variability within and among species.
Variation in migratory behavior, and in physiological and morphological adaptations to …

Although the migration ecology of birds breeding in the Neotropics is still poorly studied
relative to that of their counterparts breeding at north-temperate latitudes, studies conducted …

Aim Oceanic islands represent a special challenge to historical biogeographers because
dispersal is typically the dominant process while most existing methods are based on …

Shorebirds, or waders, form an ecologically (but not phylogenetically) homogenous group of
birds that, despite this homogeneity, exhibits clear correlated contrasts in habitat use and …

Understanding the biogeographic origins and temporal sequencing of groups within a
region or of lineages within an ecosystem can yield important insights into evolutionary …
