Live Bluebird Nestbox Camera Returns To Game Commission Website
|
|
In an effort to garner appreciation for wildlife, especially the state's bluebird population, the Game Commission launched this year's webcasting of a live video feed from a bluebird nestbox on the grounds of its Harrisburg Headquarters. "The best way to get Pennsylvanians – in fact most Americans – excited about wildlife is to show them what makes wildlife so irreplaceable and priceless," said Carl G. Roe, Game Commission executive director. "We decided to set-up and use this live webcast to help us educate the public about the importance of wildlife, how to make backyards friendlier to wildlife and also provide a way for folks to simply get closer to bluebirds. Last year, it was a huge hit, and we expect that the broadcasting of this year's activities again will be well received.
"The nestbox camera provides the public a closer look at the entire nesting process of bluebirds. I'm not sure how many people have ever seen a bluebird form a nest by plowing the materials with its wings. But nest-forming is a fascinating example of nature at work. And it's something you'll never see unless you're checking out our nesting camera."
Roe noted that a bluebird just took up residence in the box this year and is in the early stages of building a nest.
Launched last year, the bluebird camera was the agency's 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 directly behind the agency's headquarters. A live feed also is broadcast to a monitor in the agency's lobby.
New this year is the installation of an infrared video camera, which will enable visitors to tune in anytime of day or night.
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, it's 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 didn't 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 Pennsylvania's 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 bluebird's 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. "It's 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."
