Bald Eagle Nest
A pair of Bald Eagles are now nesting within 5
miles of downtown Pittsburgh, Pennsylvania along the Monongahela
River near where the famed Carnegie Steel
Homestead site once
existed. Industrialization beginning in the 19th century led to
extensive unregulated pollution of the rivers, which decimated
fish populations that eagles feed on. For example, during a
survey on Monongahela River in 1967, one scientist could find
only one bluegill. As efforts to clean the waterways took effect
over the past 30 years, 76 species of fish have been found in
the Monongahela. Experts say it has probably been more than 250
years since Bald Eagles last nested along Pittsburgh’s three
rivers. As recently as the mid-1980s, there were just a few
remaining nesting Bald Eagles pairs anywhere in Pennsylvania.
This year marks 30 years since the reintroduction of Bald Eagles
in Pennsylvania. With the help of the Canadian government,
several agencies including the Pennsylvania Game Commission
brought bald eagle chicks back to their states to reintroduce
Bald Eagles. Today, Pennsylvania boasts more than 250 nests.
Here's some recent activity in the nest. The eagles often show
up at random times during the day. We will try and post as many
video clips as we can until nesting season. Please visit our
Facebook pages for more information.

About the Webcam
This webcam is a pilot project with the
Pennsylvania Game Commission which required a vast amount of
work with the landowner, commission, and biologists to make this
a reality. The camera system was installed on December 20, 2013.
Ten Pennsylvania Game Commission conservation officers
transported and install the camera equipment with the help of
PixController, Inc. The camera system is a unique system
which was custom designed and manufactured by PixController,
Inc. The camera video feed is streamed over
Verizon Wireless 4G LTE cellular network. Verizon has
donated the data plan and bandwidth to stream the video signal
and their partner,
Wireless donate the 4G Gateway for the project. The video
stream host and player is provided by
from South Africa. Because the
system is installed in a remote location the system is powered
by a battery bank, which was supplied by
Interstate Batteries, and is solar charged. This is truly a
team effort by many people to bring this video feed to you.
The camera is a
Pan-Tilt-Zoom camera with built-in IR illuminators for night
time illumination. The camera is mounted in a tree about 30
yards from the nest site with a view down into the nest. We can
remotely move and zoom the camera and follow the eagles. During
the day the video will be broadcast in color and during the
night the video will switch over to black & white. We remotely
monitor the battery power and site security via M2M (machine to
machine) devices designed by PixController, Inc. to keep the
video feed streaming and secure without the need for human
Quick Bald Eagle Facts
- How can I tell the
male from the female bald eagle? The female is
slightly larger than the male. In the case of the
Hays bald eagles the male has a noticeable white
spot on the right side.
- Adult birds range
from 35" to 37" tall with a wingspan of 72" to 90"
and weigh between 10 to 14 lbs.
- Their diet consists
of mainly fish but will take advantage of carrion
they can find.
- The female lays 1-3
eggs 5-10 days after mating. For bald eagles in our
area we should expect eggs between February & March.
The eggs are incubated for about 35 days.
- The nest is between
6' - 8' in diameter and can weigh up to 1 ton.
- Bald eagles
typically mate for life and have a 20-30 year
- Bald eagles do not
reach maturity until they are 4-5 year old at which
time they develop the white head and tail feathers.
