Pittsburgh's pair of bald eagles apparently have a new egg a week after their nest was lost when the tree was toppled by high winds.

After losing the nest Feb. 12, the pair started to build a new nest near the old one in a tree on a hill overlooking the Monongahela River.

The Audubon Society of Western Pennsylvania said Monday that without a clear view of the new nest from a webcam, observers have deduced the presence of an egg by the birds' behavior.

People who started as strangers have become friends, spending every weekend on a portion of the Great Allegheny Passage trail, gazing upward.
