Figuring out if a nest has hatched, when you can’t see inside, is a challenge.  On Fifth Avenue, hawk watchers look for changes in behavior. 

Today, on a warm, sunny spring day, we saw two behavior changes. 

• Pale Male brought food directly to the nest rather than leaving it in a surrounding tree or terrace for Lola to go off nest and eat. They also didn’t exchange places.  Lola stayed on the nest.
• Lola spent a great deal of time fidgeting in the nest.

These behavior changes may mean nothing. If they are followed up with more behavior changes and in a few days a feeding, we’ll have good news.

But for now, they don’t mean anything.  They could easily be a false alarm caused by a warm spring day.
