How do scientists learn what Bay Area birds are eating? Come see for yourself as biologists from Point Blue Conservation Science invite visitors to watch them while they work. They’ll be studying the diets of local cormorants by dissecting the indigestible pellets coughed up by these birds. Each pellet contains tiny ear bones from fish consumed by the cormorant. Such studies offer a glimpse into the overall health of local ocean ecosystems.Point Blue Conservation Science has been assessing changes in our environment and advancing conservation through bird and ecosystem studies since its founding as Point Reyes Bird Observatory in 1965.
