Birds are everywhere, and the simple act of counting birds can help in uncovering the effects of anthropogenic disturbances, disruption of ecosystem processes and finding solutions to urbanization. I have used birds as a model taxon for more than a decade: from studying the role of invasive species on native ecosystems to the impacts of habitat degradation on biotic communities. Join us in this webinar for an exploration of key threats (biological invasion, habitat degradation and urbanization), and how birds can help us understand the impacts of these threats.
