Update from Mary

An Update from Mary Hennen at the Field Museum:

Hi Everyone!

We have chicks at a number of sites and unfortunately we lost the clutch at the Mag Mile building. Another new site has been located on the south side of the city.

If site is bolded, new information about 2010 is included. Please continue to send any reports or questions to (mhennen@fieldmuseum.org .) Keep an eye out for third bird sightings as a number of territorial fights have been observed this year. If you notice any mistakes in the following report, please let me know.
