Interspecific competition is an important process structuring ecological communities, however, it is difficult to observe in nature. We used an occupancy modelling approach to evaluate evidence of competition between yellow-billed (Gavia adamsii[...]

Haemosporidians causing avian malaria are very common parasites among bird species. Their negative effects have been repeatedly reported in terms of deterioration in survival prospects or reproductive success. However, a positive association bet[...]

Community-wide food pulses may ameliorate food constraints but may also result in increased competition for other resources and predation rates. In cavity-nesting vertebrate communities, where the availability of tree cavities can limit reproduc[...]

Parental effects are influential sources of phenotypic variation in offspring. Incubation temperature in birds, which is largely driven by parental behavior and physiology, affects a suite of phenotypic traits in offspring including growth, immu[...]

Although the diversity in avian plumage coloration is striking, there is little known about the rate with which colour diverges. Eastern bluebirds Sialia sialis bermudensis on the island of Bermuda are considered endemic based upon differences i[...]

The annual migration of small birds depends on the optimal management of time and energy. Since refueling at stopovers between flights consumes most of the birds' time and energy, selection of food-rich sites, and timely departure therefrom are [...]

We used multilocus phylogeographic analyses, morphometric measurements, and environmental niche models (ENMs) to analyze the recent evolution of the golden vireo Vireo hypochryseus, a Mexican endemic species. Vireo hypochryseus is made up of two[...]

When the northern fulmar expanded its northeast Atlantic breeding range from the two known colonies, Grimsey in northern Iceland and St Kilda in the Outer Hebrides, Scotland, about 350 yr ago, the geographical pattern of colonisation - initially[...]

In species susceptible to mass-dependent flight costs, mass recession prior to fledging may ensure that fledglings have appropriate wing loading. Our objectives were to determine if mass recession by chimney swift Chaetura pelagica nestlings is [...]

Oxidative stress has been suggested as a mediator in life-history trade-off. By spending more resources on for example reproduction an organism might sacrifice its antioxidant defence. So far, most conclusions on trade-offs between life-history [...]

Life history traits exhibit substantial geographical variation associated with the pace of life. Species with a slow pace are expected to invest more in their future/residual reproductive value and are more common at tropical latitudes, whereas [...]
