Birding connects a father and daughter whose relationship is strained by different views of the world in Odyssey Theatre Ensemble’s Los Angeles premiere of Birds of North America. In this funny, poignant and nuanced two-hander set against the background of nature and climate change, John and Caitlyn scan the skies over a backyard in suburban Maryland looking for elusive birds, even as the years go by and both they and the world around them change in small and vast ways.
