The city has gone to the birds.

So says the National Park Service, which is helping young students learn about migratory birds in Queens today.

The Jamaica Bay Wildlife Refuge in Broad Channel is one of the most significant bird sanctuaries in the Northeastern United States.

Over the past 25 years, more than 300 species of birds have been spotted there.

Today, a visiting class of fourth grade students observed birds and their habitats to collect important data on migration patterns.

It's part of a nationwide initiative called "Every Kid in a Park".

"Fourth graders have an activity," said Daphne Yun, with Gateway National Recreation Area. "If they complete an activity, they get a pass for they and their family to visit all national parks, and other sites such as fish and wildlife, I believe Bureau of Land Management, so a lot of different public areas are open to them and their family."
