Celebrate Urban Birds engages urban and rural residents in science, cultural, and community activities related to birds. Participants receive or download a free kit with posters, flower seeds, and data forms, then observe a small, defined bird-watching area for 10 minutes and report on the presence or absence of 16 species of birds. The project assesses the value of green spaces for birds, ranging in size from a potted plant to half a basketball court. Launched in 2007, Celebrate Urban Birds has partnered with nearly 5,000 community organizations and distributed more than 100,000 kits in English and Spanish. The National Forum on Children and Nature selected Celebrate Urban Birds as one of 30 nationally significant projects to connect children with the outdoors.
