Recommendations for selecting an arthropod sampling method Since many birds are insectivorous, their study often requires an accurate understanding of the arthropod prey community, including studies into resource selection, dietary overlap, and drivers of population density. However, ornithologists struggle to properly apply arthropod sampling techniques for a variety of reasons. First, there are many different arthropod sampling methods to choose from, each with their own problems and biases. Secondly, some habitats, such as forests, are structurally complex, with many different microhabitats that likely have different arthropod communities. Therefore, the central problem for ornithologists selecting a sampling method is that the arthropod community sampled by the selected method must align with the community of arthropods available to the study species.... continue reading.
A review of threshold responses of birds to landscape changes across the world Habitat loss is recognized as having one of the most severe impacts of human activity on biodiversity. Threshold of habitat cover is a concept used in ecology and landscape ecology to define the breaking point beyond which species are locally lost. Identifying such thresholds is an important task not only for scientists to predict the state of a given ecosystem, but it also has great potential for environmental policy-making and conservation practice. A new review by Isabel Melo and colleagues published in the Journal of Field Ornithology compiles all the 31 studies of habitat cover threshold responses dealing with birds worldwide since the threshold concept was first... continue reading.

The Association of Field Ornithologists (AFO) wants your help in designing a logo concept for its business Avinet that specializes at providing essential field supplies to wildlife researchers. AFO’s research supply company began as a distributor of mist nets to ornithologists in the 1950s and has continued to grow to include other essential products to wildlife researchers. In 2016, AFO made purchase of the assets and operation of Avinet, Inc. and has merged operations with Avian Research Supplies.... continue reading.
