Article
The structural and physiognomic characteristics of forests and mountain forest are fundamental aspects that influence the richness, abundance and composition in the bird community. The objective of the present work was to analyse how the vegetation structure could influence the species composition of mixed-species flocks (MSF), along the latitudina...
Article
The escape behaviour, measured as flight initiation distance (FID; the distance at which individuals take flight when approached by a potential predator, usually a human in the study systems), is a measure widely used to study fearfulness and risk-taking in animals. Previous studies have shown significant differences in the escape behaviour of bird...
