| HARRISBURG With four of five eggs hatched, the Pennsylvania Game
Commissions webcasting of a live video feed from a bluebird nestbox on the grounds
of its Harrisburg Headquarters now is providing viewers a chance to watch the adult
bluebirds feed their chicks.
To view the live feed, visit the agencys website (www.pgc.state.pa.us) and click on the Bluebird Nestbox Cam icon
under the opening photo in the center of the homepage.
After several weeks of nest building and waiting, the bluebird nestbox camera now
is allowing viewers to follow along with an active nest that presently contains four
bluebird chicks, said Carl G. Roe, Game Commission executive director. The
best way to get Pennsylvanians in fact most Americans excited about wildlife
is to show them what makes wildlife so irreplaceable and priceless.
In late April, the female bluebird laid five eggs, of which four hatched beginning May
13. It is expected that the fifth may not
hatch, as it is not uncommon for one egg from a clutch to turn out to be infertile or fail
to hatch. Depending on conditions, the four chicks may fledge leave the nest and
fly on their own by the end of May or early June.
Launched last year, the bluebird camera was the agencys first foray into the
world of live nest camera feeds. It provides a color video feed plus audio from the
bluebird nestbox quarters, which is situated near the agencys headquarters. A live
feed also is broadcast to a monitor in the agencys lobby.
New this year is the installation of an infrared video camera, which will enable
visitors to tune in after dark, too.
We decided to set-up and use this live webcast to help us educate the public
about the wildlife, encourage them to make their backyards friendlier to wildlife and also
provide a way for folks to simply get closer to bluebirds, Roe said. Last
year, it was a huge hit, and we expect that the broadcasting of this years
activities again will be well received.
Steps are taken to deter house sparrows from using the nestbox by mounting monofilament
fishing line from the roof over the entrance hole, which compels sparrows to stay away.
Bluebird nestboxes placed close to buildings almost always attract competition from
sparrows, which annually chase native bluebirds from nestboxes and nesting cavities.
In the early 1960s, the eastern bluebird was hanging on for dear life, said
Dan Brauning, Game Commission Wildlife Diversity Section supervisor. The species was
suffering from a European invasion of house sparrows and European starlings. Today,
its not hard to imagine the harm that would come from releasing starlings and house
sparrows in New York City during the 1800s. But back then, at a time when people were
trying to reverse declining songbird populations, it seemed like the right thing to do in
New York.
The starling spread quickly across America. Released in 1890 and 1891, starlings
were building nests in California by the 1940s. What our forefathers didnt expect,
in addition to the rapid range expansion of these alien species, was that they would
almost immediately begin competing with bluebirds and other beneficial songbirds for
cavity nesting sites.
Bluebirds were enjoying a satisfying existence around 1900. It is when some
ornithologists believe Pennsylvanias bluebird population was at its largest, because
fully two-thirds of the Commonwealth was farmland. But the runaway populations of
starlings and sparrows would begin to compete with and ultimately cripple the
bluebirds ability to secure adequate nesting.
The species problems would be further compounded by farmlands reverting to
forestland or being swallowed by development, the increased use of pesticides, and the
replacement of wooden fence-posts with metal posts.
By 1960, the bottom was ready to fall out, and the Game Commission and many other
conservation agencies and organizations launched an aggressive campaign to rescue the
species. With the aid of its Howard Nursery,
the Game Commission manufactured inexpensive bluebird nestboxes and bluebird nestbox kits
for the public to place afield. Boy Scouts and Cub Scouts became involved, as well as 4-H
Clubs, schools and Audubon chapters. Bluebirds became the poster child for efforts aimed
at getting people to do something for wildlife in their backyards.
Today, bluebirds are back in a big way, even in the southeastern counties, where
they compete heavily with large populations of house sparrows, Brauning said.
Its fair to say that our bluebird population is stronger today than it has
been in 50 years. With time and continued assistance from caring Pennsylvanians, it seems
likely bluebirds will continue to prosper.
