In January 2009, two Red-tailed Hawks built a nest on a window ledge at The Franklin Institute in Philadelphia. The nest sits just outside a window where a camera has been positioned to create this video stream. The camera looks through the glass window pane. No artificial lighting has been added, so the nest is only visible during daylight hours.
The nest was productive in 2009 and it is again now! Two hatchlings hatched already and one is about to! You can watch it live, here:

“No artificial lighting has been added, so the nest is only visible during daylight hours.”
So why didn’t those dudes at The Franklin Institute think of setting up an infrared camera? Like this one: http://www.gardengiftshop.co.uk/ggs_wireless-colour-bird-box-camera.aspx?pid=99081
