Are your dreams sometimes filled with birds? Perhaps, it’s because they are flying over you as you sleep! You may have heard that a vast multitude of birds migrate at night. While it is now fairly popular to watch birds migrating at daytime, you may have wondered, how on earth can we experience bird migration at night? Andy will try to help you unlock the secrets of how to witness and record this hidden bird migration happening across our skies at night.

Andy has been birding LA County for 25 years and lives with his young family in Los Feliz. He can usually be found birding Griffith Park and the LA River around Glendale and Los Feliz. Over the past 30 years, he has illustrated identification plates for field guides and birding magazines in North America and Europe.
