Blood parasites exert significant selective pressure, which can alter population dynamics, and the introduction of new parasite lineages in a region could lead to the extinction of endemic avian species that have not coevolved with them. The avi[...]

Human–wildlife conflicts around the loss and use of habitat are common reasons for species being listed as threatened. In order to reduce such conflicts it is important to have a clear understanding of the resource requirements of threatened spe[...]

Assessing future changes in the suitability of the climate niche for interacting species across different trophic levels can identify direct and indirect effects of climate change that may be missed using single-species approaches. We use ensemb[...]

Conventional dietary studies combined with stable isotope analysis allowed the characterisation of the trophic niche of South American Terns (Sterna hirundinacea) breeding in Argentina. Direct observation of prey deliveries during mate- and chic[...]

Climate and rainfall in southern Australia are strongly influenced by the El Nino–Southern Oscillation (ENSO) phenomenon. If breeding of forest birds is related to rainfall, then ENSO may influence fluctuations in breeding activity. We recorded [...]

Neotropical ovenbirds (family Furnariidae) are largely sexually monomorphic and monochromatic, which leads to the assumption that sexual selection has had little effect on the evolution of the morphological and plumage traits of the species in t[...]

To monitor assemblages of animals, ecologists need effective methods for detecting and recording the distributions of species within target areas in restricted periods of time. In this study, we compared the effectiveness of a traditional avian [...]

Very few bird species are able to complete a single long migratory flight. Instead, a far more common strategy is that birds rest and feed almost every day, accomplishing their journeys in a series of short flights. We evaluated if White-crested[...]

All organisms are exposed to a variety of physical, environmental and psychological challenges throughout their lives. We administered repeated oral doses of the stress hormone corticosterone (CORT) to ovulating Zebra Finches (Taeniopygia guttat[...]
