Spring migration is one of the Research and Community Science Team's favorite times of year. For the fourth year in a row, we are hosting our Green Birding Challenge (GBC), the Team's signature annual fundraiser! Do you enjoy spending time outdoors hiking or biking, or just sitting and listening to the sounds of nature? If so, this year's GBC, held on Saturday, May 10th, is the event for you! Get out your walking shoes, dust off your lawnchair or pump up your bike tires and participate in a little competitive birding. Register a team for one of our four challenges: stationary birding, birding on foot, birding by bike, or a mini-challenge. Your participation will help us celebrate International Migratory Bird Day and help raise money for bird conservation and community science!
