We used variable-radius point counts and mist-netting to estimate forest bird abundances in the Maule Region of South Central Chile. Mist-netting detected a total of 25 species over 3 years and 3 seasons per year (Winter, ...

In the field of geology, as in many other fields, a common problem is the analysis of 2D sections. An example of this is the petrographic study of rock samples, i.e., the quantification of its mineral components and the ...

Roadside point counts are often used to estimate trends of bird populations. The use of aural counts of birds without adjustment for detection probability, however, can lead to incorrect population trend estimates. We ...

Point counts are widely used to assess bird diversity. However, this method has some limitations and can be affected by observer bias. For this reason, it is commonly complemented with other methods (e.g., mist-nets, sound ...

As urban areas expand, some species of diurnal birds of prey occupy these habitats, and many establish viable populations. The objectives of this study were to: (1) survey the species of birds of prey in the urban area ...
