When does this drive through open?

Yesterday Nana, Elena, and the pigeons had a bit of excitement. This hawk, a female Coopers Hawk I believe, decided to take a look and see if she could get into the aviary for a bite to eat before the ice storm.



She walked around and around the aviary and loft, even went _under_ the loft, for about 15 minutes before Nana and Elena decided enough was enough and went out to scare her off. The birds were none the worse for wear by the time I got home after dark to close them up, but Elena was excited enough to still be awake!
