Pennsylvania is the sixth most populous state in the United States of America, with most of the population concentrated in the eastern and western parts. The central part mostly has farmlands, forests, and mountainous terrain, thus being more prominent as a birding hotspot. Besides this, the Pennsylvania side of Lake Erie in the north-western corner of the state has a 43-mile shoreline, being a favorite spot habitat for water and migratory birds.
The Pennsylvania Ornithological Records Committee accepts 435 bird species living in Pennsylvania, according to the July 2020 list.
The ruffled grouse has been designated as Pennsylvania’s official state bird since 1931.
