2009 nesting season highlights:

What happened to the 2nd eagle chick?
Those who have been watching the Libby Dam Bald Eagle Cam probably have noticed there is only one chick in the nest now. We asked the folks up at Libby Dam if they know what happened to the second chick? Here is the answer from Libby Dam Park Ranger Mark Andreasen:“ On Saturday May 16, 2009 one of the eaglets died from unknown causes. It's not uncommon for eaglets to die in the early stages of development. Death may occur from natural causes, predators, competition for food, or even Fratricide (killing of one's sibling).”

2008 Nesting Season Overview: The eagles were first seen on the nest in late January. Nest tending activity occurred over the next several weeks. On March 19, the first egg was observed in the nest, followed a couple of days later by a second egg seen on March 24th. Eaglets hatched around May 5th. By the end of July the eaglets were actively testing their wings and flying in and out of the nest.

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 9.00.00.2800 Windows Media Server: COE-COMPUTER " Windows Media Services 9.00.00.3380.

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.
