Continental phylogeography of an ecologically and morphologically diverse Neotropical songbird, Zonotrichia capensis
The Neotropics are exceptionally diverse, containing roughly one third of all extant bird species on Earth. This remarkable… (More)

Variation in the gonadotrophin-releasing hormone-1 and the song control system in the tropical breeding rufous-collared sparrow (Zonotrichia capensis) is dependent on sex and reproductive state.
Seasonal breeding in temperate zone vertebrates is characterised by pronounced variation in both central and peripheral… (More)

The Role of Cultural Divergence in Reproductive Isolation in a Tropical Bird, the Rufous-collared Sparrow (zonotrichia Capensis)
In addition to the observed high diversity of species in the tropics, divergence among populations of the same species exists… (More)

Seasonal and social modulation of testosterone in Costa Rican rufous-collared sparrows (Zonotrichia capensis costaricensis).
Previous work shows that most birds breeding in northern temperate regions adjust production of testosterone in response to stage… (More)

The effects of combined aromatase inhibitor and anti-androgen on male territorial aggression in a tropical population of rufous-collared sparrows, Zonotrichia capensis.
Territorial aggression, exhibited by male vertebrates in a reproductive context, is generally thought to be mediated by elevated… (More)

Plasticity of the avian song control system in response to localized environmental cues in an equatorial songbird.
A striking feature of the vertebrate brain is its plasticity. In high-latitude vertebrates, seasonal plasticity of the brain is… (More)
