Trupti Atkari's daughter, Anna, takes part in the bird count for kids. Armed with binoculars and a photo identification guide, families searched the water for bird species and recorded what they found. The annual Christmas Bird Count is the longest-running citizen science project in North America, said Becky Parker, executive director of Nature Nova Scotia. Jeorge Sadi/CBC"The Christmas bird count since 1900 has been really valuable for generating oodles of data from sites across North America," Parker said. The data is then submitted to a database that can help researchers track each bird species.
