Guide to North American Birds

One of the rarest North American birds, and also one of the largest and most magnificent. Once fairly widespread on the northern prairies, it was brought to the brink of extinction in the 1940s, but strict protection has brought the wild population back to well over one hundred. The flock that winters on the central Texas coast flies 2400 miles north to nest in Wood Buffalo National Park in central Canada; this remote breeding area was not discovered until 1954.
