Online Talk: Why do Birds Fall Out of the Sky?

Time : 10am - 11am
Location : Hosted on Zoom by Dr Yong Ding Li (Bird Group) and Gloria Seow (Education Committee)

Open to the Public - Registration Needed

Bird-building collisions are estimated to kill up to 1 billion birds annually in the United States. Outside of the US, this phenomenon is poorly understood. Why do birds knock into buildings? What species are the most vulnerable to building collisions? Join David Tan in this talk as he presents the results of a 7-year long citizen science study conducted in Singapore, exploring where, when, and why birds collide with buildings. As one of the first studies conducted in Asia, it provides useful insights into how we can reduce the number of bird-building collisions in Singapore, and make our city a bird-friendly one. The talk will wrap with a Q&A segment.
