Identifying the composition of avian diets is a critical step in characterizing the roles of birds within ecosystems. However, because birds are a diverse taxonomic group with equally …
Quantifying individual specialization and other forms of intraspecific ecological diversity can reveal variation that is critical for evolutionary or behavioral adaption of a species to …
The intensification of land‐use changes in tropical forests during the 20th century, mainly caused by deforestation for agricultural uses, had an overwhelming influence on bird …
Niche partitioning is a widespread ecological strategy within trophic guilds, ensuring the coexistence of sympatric species by reducing interspecific competition. Stable isotope …

Stable isotope analysis is a valuable tool in food web studies. This increasingly available technique is useful because the stable isotope composition of a consumer reflects that of its …
Although stable isotopes have been increasingly used in ornithology since 1980 in many places, Brazil has been slow in adopting this methodology, especially when it comes to …
Darwin's finches are a classic example of adaptive radiation involving differential use of dietary resources among sympatric species. Here, we apply stable isotope (δ13C, δ15N …
