Watch the recording of the talk: Changes in Bird Populations due to Urbanization over 25 Years

Published by Steve Clark on

Dr. Daniel Cooper, who spoke to us via Zoom on Thursday evening June 10th, gave a scholarly presentation of his research into the changes of bird populations over the past few decades due to expanding urban areas. He finds that some species thrive in cities, some avoid them, and others seem to be indifferent. Following his presentation he engaged in a far-reaching question and answer session that touched on specific species in defined areas as well as more general trends.

Here are a few screenshots of his presentation.

Dr. Cooper has investigated the role of ecological and behavioral traits for more than 50 species of nesting birds in the Los Angeles area since 1995. Bird populations in urban areas are in constant flux, with some species adapting and thriving while others decline. He will discuss trends, explore traits that appear to confer success, and offer predictions as to which will continue to thrive. He will also propose conservation steps for those species that are declining.

Daniel S. Cooper, Ph.D. is an expert on the birds of Southern California. He is President of Cooper Ecological Monitoring and a researcher at the Los Angeles County Museum of Natural History. He has spent more than 20 years conducting surveys and analyzing bird populations from the deserts to the coast, including rare and protected species such as the California Gnatcatcher and the coastal Cactus Wren. Dan and his family live in Oak Park where he enjoys the natural outdoor beauty.
