2009 Nesting Season Overview: Nest tending activity occurred over January and February. The first egg was observed in the nest on March 18th. On March 25th a second egg was observed. The eagles endured repeated snowy conditions while sitting on the eggs. On April 24, two eaglets hatched. On May 16th, one of the chicks disappeared from the nest for unknown reasons. The remaining chick fledged (left the nest) in mid-July.

Libby Dam Eagle Cam: The Libby Dam eagle cam is located near Souse Gulch on the Kootenai River. This nest began in 1996 and has been active for the past 10 years. Two eggs were laid in the nest in April, 2006. Eaglets hatched in May. Both adults take turns tending the nest.

Look at the column to the right for historical information about the nest, eaglets and how many fledglings since 1996. In general, the nest becomes active in March and eaglets fledge in late July or early August. A breeding adult pair produces 1-2 young eaglets each year.

Camera Equipment:
Camera: Pelco Color Surveillance Camera Windows Media Encoder: COE-COMPUTER " Osprey 100 PCI video capture card " Belkin F5U204 USB video dongle " Windows Media Encoder Windows Media Server: COE-COMPUTER " Windows Media Services

Camera Setup:
The camera is a Pelco color surveillance camera with a 2-10 mm zoom lens. It is zoomed in at about 4 mm to include the entire nest bowl. The camera and lens are housed in a Pelco sealed, weatherproof, camo painted, outdoor enclosure with heated interior. The small heater inside the enclosure keeps the lens from fogging up.

The enclosure is attached to the branch with lag bolts and is approximately 100' above the ground. The camera and heater run on 24 volts ac. There is a 120:24 volt transformer in the enclosure in which 120 vac supplies the equipment.

One power and one signal (coax) cable go down the tree to the ground. From there they go 600' underground to the Libby Dam weather station which overlooks Lake Koocanusa. At the weather station the eaglecam picture signal goes to a microwave transmitter and is transmitted about a mile, at a baud rate of 115,200 kbps, to a receiver on top of the Libby Dam Visitor Center. From that receiver a coax cable goes down into the Visitor Center ceiling. In the Visitor Center ceiling the signal is split two ways. One goes to a monitor in the Visitor Center display area where the public can view the live broadcast on a television monitor. The other way goes to the Visitor Center basement where there is a computer that broadcast it over the local area network and to the internet.
