The Peregrine Falcon is the national animal of the United Arab Emirates, and the official city bird of Chicago. It also makes an appearance on the 2007 Idaho state quarter.

The falcon sits in her box often, fluffed up. Is she sick?

When sitting in her box for long stretches of time, she has eggs that she sits on. While sometimes feather fluffing is a sign of illness, more often than not, she might either be keeping warm in cold weather, or in the process of laying eggs.

The falcon pants a lot and holds her wings open. What's wrong with her?

Nothing is wrong. Birds act this way in warm weather. When "panting," this is actually called "gular fluttering." Tower Girl is keeping cool. We have a good article on this process here.

A male falcon was around for a while. Where did he go?

Most likely he has continued migration northward. It is likely he has a territory and long-term mate in the normal breeding range.

I haven't seen Tower Girl in a while. Where does she go?

Tower Girl spends more time in her nest box during the spring and early summer, if she has laid a clutch of eggs. Outside of this time period, she spends less time in her nest box. It's not uncommon for her to not appear for weeks at a time as there is little reason for her to be in the nest box without eggs or chicks to attend to. She is most likely out hunting, or possibly hanging out at other buildings around Austin. As the bird is not banded, we are unable to track her movements outside of what is visible on the camera.

She often stands on one leg and curls the other. Is something wrong with her foot?

Birds rest that way just like a horse will bend and rest one leg at a time.

When does the falcon lay eggs? When do they hatch?

The falcon lays eggs sometimes in March, after the January or February mating season. The floor of the box is depressed slightly to avoid eggs rolling out. The standard incubation period is counting around 30 days from the third egg, then add a few additional days for "error."

The eggs seen in the nest box in 2018 never hatched. See this article in the Austin American-Statesman for more details about why Tower Girl would lay eggs that don't hatch:

KXAN also ran a short piece on this as well in 2018: https://www.kxan.com/news/local/austin/eggs-spotted-in-tower-girls-nesting-box/

It's not uncommon for wild birds to lay eggs that are not viable.

When was the nest box installed?

Construction Services installed the nesting box in February of 2014.

Has Tower Girl laid eggs in the past?

Yes, we discovered four eggs in March 2016. In 2017, she laid four. In 2018, when the camera was installed, she laid three. In 2019, she laid four. In 2020, she also laid four.

The camera appears to be offline. When is it coming back?

Sometimes due to storms in the area or other technical issues, the camera will be offline. Trust that we are working to remedy the problem, but cannot give definite time frames when the camera is returning. We also encourage you to refresh your browser, as the issue might be on your computer.
