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
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 brought bald eagle chicks back to their states to
reintroduce Bald Eagles. Today, Pennsylvania boasts more than

About the Webcam
The camera system is a unique system
which was custom designed and manufactured by PixController,
Inc. The camera video feed is streamed over
a cellular network. 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.
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.
