Take the National Parks birding quiz

Did you know that the ruby-throated hummingbird breeds throughout the eastern U.S. but that other hummingbird species are seldom seen in the eastern U.S? Or where is the location of the largest seabird colony in the US?

But I bet you already knew that some trumpeter swans over winter in Yellowstone National Park, while others migrate south, and that all of the more than 300 California condors alive today, including about 170 living in the wild, are descendants of an original 22 birds that were captured in Southern California and put into a captive breeding program.

These birding facts and more are part of a National Parks Traveler teaser, the National Park System Quiz 73: Birds. Try the test yourself and see how knowledgeable you are on the birds of the National Park system.
