Swifts Flying Down a Chimney

The swifts flying was wonderful. They were flying in circles and were very pretty looking. We saw about 3,000 of them. A hawk swooped down low and the swifts chased it away. 

The swifts spend springs and summers in North Carolina. They come up in early April and nest in chimneys. In late September, they go back to South America. But the swifts are having trouble because people are putting caps on their chimneys, so they have less places to nest.
