We know that anthropogenic sounds can impact an individual bird’s calling behavior. However, it is less clear whether human noises disrupt important social communications such as alarm calls, and how that impact might be felt. With an innovative triangulation approach, Faiza Hafeez from the University of Nebraska-Lincoln, will use Song Meter SM4TS recorders to map alarm calls as they propagate through colonies of individually-identifiable red-winged blackbirds. Demonstrating this method can accurately map a species’ communication network will be the first stage to more fully understanding the impacts of noise pollution on wildlife.
High rates of deforestation in Brazil’s Eastern Amazonia region has left rare and threatened birds living in just a few remnants of primary forest. Identifying which forest fragments are most important for conservation action is no easy task. Indeed, one species, the Belem Curassow, is so secretive it was thought to be extinct until 2013. Pablo Vieira Cerqueira from the Universidade Federal do Pará will use Song Meter SM4 recorders coupled with the clustering feature in Kaleidoscope Pro to find and monitor 15 bird species, including the Belem Curassow and the critically endangered Black-winged Trumpeter. The project will also create a record of the soundscapes of these threatened habitats and will use sound recordings in its outreach work.
African Wild Dogs are highly endangered. Approaches to their conservation include translocation and forming artificial packs, requiring periods in captivity. Appeasement pheromones are a potential way to reduce stress and aggression in captive dogs. Pia Riddell from James Cook University will use Kaleidoscope Pro’s clustering feature to compare vocalizations in packs with and without exposure to the pheromones. She hopes ultimately to determine whether vocalizations can be used as an indicator of the social cohesion of an African Wild Dog pack.
