Pennsylvania Migration Count
Last Saturday, our staff participated in the 15th successional Pennsylvania Annual Migration Count (PAMC).
The count takes place each spring on the second Saturday in May. Last year, 704 observers from 40 counties across Pennsylvania participated in the count and 219 species of birds were observed.
The Pennsylvania Migration Count (PAMC) was established to gather annual data on migratory bird populations, and to help answer some questions regarding bird distribution throughout the state. Essentially, the PAMC is an annual, one-day snapshot of bird populations. The count data help answer many questions: which species are present locally, and where are they found? How many individual birds are out there? Do migratory patterns change from year to year? Do populations of specific species change from year to year? Which species are thriving and which are struggling? By identifying declining or otherwise at-risk species, it is hoped that steps can be taken toward assisting their future survival.
This one-day snapshot is also a reflection of the success of the Brandywine Conservancy and other local organizations in preserving and managing open space. If it were not for the thousands of acres of protected land in the region and well-managed natural areas, migratory birds would not have ample opportunity to re-fuel on their northward journey to their breeding grounds. In addition, many of the birds observed on the count are species who breed locally. Thus, they have found habitats that contain all the necessary components of a healthy ecosystem (food, water, shelter, and space) in which they can successfully raise their young. The Pennsylvania Audubon-designated Laurels, King Ranch and Stroud Important Bird Area is a wonderful example of local land trusts working together to preserve land not only for future generations, but also for the flora and fauna that abound.
As in past years, our staff participated in the count for Western Chester County, an area that includes the Laurels Preserve and surrounding lands, most of which are subject to Conservancy-held conservation easements. On last year's count, we recorded 96 species of birds. This year, the goal was 100 species or bust! The team began at 5:00a.m. in the Laurels and by early afternoon, had reached their goal of 100 species.
