  • Breeding Birds of Rothrock State Forest, Central PA
    part of Big Flat and ends near Whipple Dam State Park The Broad Mountain route is eastern most starting near Greenwood Furnace State Park traversing the flanks of Stone and Broad Mountains before dropping to the valleys between the two Broad Mountains Together these cover the state forest s predominant habitats The most common breeding birds are typical of central Pennsylvania Red eyed Vireo and Ovenbird which together comprise about one in three breeding birds can be found almost anywhere in the state forest Yellow billed Cuckoo Acadian Flycatcher Worm eating Warbler Hooded Warbler and Scarlet Tanager can be found in similar numbers along all three BBS routes Because of special habitat requirements most other species tend to concentrate in certain parts of the state forest A number of species are more commonly found on the Tussey Mountain route than on the other two routes particularly on the first 33 stops along the south side of the ridge Here the elevation is generally about 1200 1500 feet above sea level and conditions tend to produce taller and faster growing oaks than in some of the higher elevations The species more common here include Mourning Dove Red bellied and Pileated Woodpecker s Eastern Wood Pewee Great Crested Flycatcher Tufted Titmouse Blue gray Gnatcatcher Wood Thrush Cerulean Warbler American Redstart Rose breasted Grosbeak and Indigo Bunting Many of this cohort attain some of their highest regional densities at the nearby Frankstown Branch of Juniata River IBA along the Lower Trail Some of them also tend to be much more common in the southern half of Pennsylvania than in the northern half A set of boreal species whose ranges extend south into the Appalachians from Canada tend to be more commonly found at the higher elevations of the northeastern part of the state

  • Changes in PA's breeding birds since the first Atlas
    forest birds abundance is much higher within Pennsylvania compared to other places within the region Conversely some species are much more abundant just outside Pennsylvania s borders The majority of Pennsylvania s forest birds appear to be increasing Among these the boreal birds whose distributions follow the Appalachians south from their northern heartland have generally fared very well For species that have special habitat requirements a route with high density may be close to other routes with much lower density For such species be cautious in making conclusions about increases as the addition of a few routes can have a large influence Black throated Blue Warbler may be an example of this For several forest birds decreases in BBS counts have occurred within a broad belt from northwestern Pennsylvania to the Adirondacks Acid deposition has been blamed in the decline of Wood Thrush within this area Data for Least Flycatcher Eastern Wood Pewee and Veery suggest possibly similar trends Birds of farmlands and of early successional habitat have generally fared less well than the forest birds Ring necked Pheasant and Northern Bobwhite either no longer occur as naturally reproducing populations in many locations or are in much lower densities than during the first atlas Others such as Red winged Blackbird Vesper Sparrow and Brown Thrasher dropped sharply in number during the 1970s and early 1980s but now appear as if they are stable in number You can see the great success of some species Canada Goose is spreading from southeast and northwest Red bellied Woodpecker and Tufted Titmouse continue their surge northward while Eastern Bluebird and Tree Swallow appear to have benefited from more nest boxes being deployed These graphs contain much more information than is described here See for yourself Nick Bolgiano 711 W Foster Ave State College PA
