YORK, Pa. — Undergraduate students Cheyenne Baughman and Nhi Nguyen are gaining skills and experience through a work-study research opportunity at Penn State York. Jorge Santiago-Blay, a biology faculty member, who holds a doctorate in entomological sciences from University of California, Berkeley, has been studying elements of the wildlife at Nixon Park in York, Pennsylvania, since 2018. Most recently, he has brought students under his wing for a new project about birds.
While Santiago-Blay’s research at Nixon Park has primarily centered around bee biodiversity, redbud tree biology, and lichen conservation, his newest focus has fallen to the collection of bird specimens housed at Nixon Park’s Nature Center, which was garnered by naturalist and York County native, George Miller (1834-1915).
According to a 1922 publication by Atreus Wanner, “The [George Miller bird] collection, with very few exceptions, came from York County. It could not be duplicated now, so rapid has been the destruction of bird life. Some specimens are no longer seen in this locality. A few are rare anywhere. One, the wild pigeon, once so abundant, is now extinct. It is represented in the collection by a beautiful pair of birds.” As Wanner states, the Miller bird collection at Nixon Park also includes two rare specimens of the passenger pigeon, which are on display for the public to appreciate. Once plentiful in North America, this species was declared extinct in 1914, the year before Miller’s death.
The disappearance of many native plants and animals can be attributed to environmental factors, including industrial development and pollution, according to Santiago-Blay. For example, many species of lichens are sensitive to air pollutants and are believed to have disappeared from the woodlands of York County and many other places. Conversely, Santiago-Blay has collected about a dozen species of bees that had not been previously reported within York County.
Although biodiversity is not an easy web to untangle, Santiago-Blay hopes to uncover connections that could improve our understanding of native species and potentially contribute to conservation efforts.
