Birdsongs serve as a primary mode of communication for birds and contain a wealth of information. Birdsong classification can study the distribution, quantity, population structures, and habitat of various bird species, thereby assisting in protecting ecosystem diversity. With the advancement of computer...

In this study, we present a novel classification framework based on a pre-trained AudioNet model. In order to improve the performance of bird sound classification, the attention mechanism is used to generate important features and gated recurrent unit is used to capture temporal information. The ...
We recommend a hierarchical system for classification of male and female Peruvian Boobies: (1) use of vocalizations, (2) use of body weight and wing chord when the bird did not vocalize and was weighed immediately after daybreak or before the first feeding trip of the day, and (3) use ...

The identification of animal behavior in video is a critical but time-consuming task in many areas of research. Here, we introduce DeepAction, a deep learning-based toolbox for automatically annotating animal behavior in video. Our approach uses features extracted from raw video frames by a pretra...
