NOTE: This is an exciting time at the Hanover
eagle nest. While we appreciate concerns regarding the safety and security of
the eagles, we remind everyone that the microphone has the potential to pick up
every-day sounds of human activity in the area. The nest was built after the
homes were already present and eagles have nested here for several years
without signs of disturbance from activity at the homes. We must recognize that
if the eagles did not feel safe here, they would not be here; they would have selected a new nest location.
March 22 - As of approximately 3:30 yesterday afternoon, the two eggs were left unattended and exposed to
winter conditions. We believe that these eggs are no longer viable. Nature can
be difficult to watch. The Game Commission manages eagles in
Pennsylvania as a population, not just individuals. Other nesting eagles,
including those further north, also experience threats from winter weather and
animal encounters. Despite some nest failures, the eagle population continues
to thrive. If there are other adult eagles in the area, it is an unlikely possibility that eagles could
renest at this site. Thanks for your passion for Pennsylvania wildlife.
March 20 - What about those other eagles? While the Game Commission does not have a biologist on the ground in the
area, it does appear that there may be another adult eagle around the nest.
“Extra” bald eagles may be adults that have not yet paired up and claimed a
territory; they may attempt to interfere with this pair in order to claim a
mate or territory. With the population filling the available habitat in
many parts of Pennsylvania, it would not be surprising to see some increase in
nest failure as a result of these interferences and competition disrupting the
care of nest and young. The big take-away lesson, bald eagles are well-adapted to
Pennsylvania. They are well-adapted at selecting nest sites, building nests,
and caring for eggs and young. This is one of the great lessons of the Game Commission’s bald eagle recovery effort and its annual monitoring of active
eagle nests. As bald eagles are filling available habitat in some parts of the
state, there will be some conflicts between competing eagles. We
have never in modern history been witness to such conflict events and we will
all learn as we go. In most conceivable circumstances, nature will
be allowed to take its course without intervention. Should an injured eagle end
up grounded, the Game Commission could facilitate it’s transfer to a licensed
March 20 - How do bald eagles manage cold weather and snow? Adult eagles deal with cold temperatures by fluffing out their feathers for insulation and finding protected areas to roost. Eagles also develop a brood patch when breeding. A brood patch is an area without feathers that contains numerous blood vessels. The brood patch allows the adult eagles to easily transfer heat from themselves to the egg(s). Female bald eagles have larger brood patches than males, which implies that the females do a larger portion of the incubation and brooding. Snow on an eagle nest is not cause for alarm. More than 300 other wild eagle nests across the state have also experienced snow, ice, and wind this winter and in previous years and the population continues to soar.

March 19 - The streams were disrupted over the weekend. The issue was resolved after power was restored. We thank our partners at HDOnTap, Comcast Business, and Codorus State Park for making this stream possible and troubleshooting with us.
February 23 - A second egg arrived shortly after 6pm.
February 20 - The first egg of 2018 appeared around 3:30 in the afternoon. A second egg could appear by the 23rd. Since we have been live streaming this nest, eggs have arrived between 3:15 and 6:00 p.m.. If all goes well, we can expect the first egg to hatch at the end of March.
January 2018 - Video and audio streams from two cameras at the nest site went live on January 3. One camera is a side angle and the other a view from above, which also has infrared capabilities for night viewing. Sometime in late fall a large part of the nest fell. The remaining structure is quite a bit further down the tree and much smaller. The adults continue to bring sticks, corn stalks, grasses, and other materials to nest.
December 2017 - Staff members from HDOnTap and Codorus State Park worked through the cold and wind to replace and rewire cables at the nest site. Some of the nest had fallen. Two adult eagles have been frequenting the site with nesting material.
Highlights of 2017 - The Hanover bald eagle family had a successful 2017 season with both eggs hatching and both nestlings fledging. The first egg appeared on the evening of February 10 and the second on the evening of the 13th. March 20 broke with a new eaglet in the nest and second hatched the following day. The eaglets began branching over the Memorial Day holiday and by mid-June we weren't seeing much of them. The live streams closed on July 11. We thank the landowners, neighbors, and Codorus State Park staff for being our eyes, ears, and feet on the ground. We thank HDOnTap for providing the live stream service and Comcast Business for providing the necessary internet connection. We thank you all for watching and learning about Pennsylvania wildlife with us.
Highlights of 2016 - The live stream began December 17 shortly after the installation of two new cameras and audio equipment. Eggs were laid on February 18 and 21. March 28 one of the eggs hatched; the nestling died two days later, perhaps injured by a branch being moved in the nest. The other egg never hatched and remained n the nest until May 23 when one of the adults removed the remnants from the nest. There are many factors that can influence the success of a nest. We do not know what caused the nesting failure in this specific instance. We do know that the eagles using the Hanover nest have produced successful young during many past years, and that they have had nest failures in other years. This is not an uncommon occurrence for raptors, nor for wildlife species in general. The stream was shut down on June 1st so agency staff could devote time to other projects.
Highlights of 2015: Eggs were laid on February 14 and 17. Adult eagles were covered in snow on the nest on March 5 drawing international attention. The eggs hatched on March 24 and 25. The two young eaglets fledged around June 22nd.
A bit of history on the Hanover nest: The first record of an active nest in this area is from 2005. Records indicate that eaglets have fledged eight times, most often two at a time. There are no records indicating that any of the adult nesting eagles have been banded or otherwise marked. These cameras (provided by HDOnTap) were installed in November 2015. The cameras are powered by a hard line running down the tree to an electrical panel several feet from the base of the tree. Comcast Business is providing the internet service. Together, these partners are creating this dependable, high-quality stream. Friends of Codorus State Park supplied the bucket lift and other items necessary for installation and the landowner is donating the electricity to power the camera. Codorus State Park staff have been instrumental with on the ground staff and in facilitating this project. The Game Commission is grateful for all those involved in providing this spectacular view of nature at work.
