Central Park contains various migratory birds during their spring and fall migration on the Atlantic Flyway.[87] The first official list of birds observed in Central Park, which numbered 235 species, was published in Forest and Stream in 1886 by Augustus G. Paine Jr. and Lewis B. Woodruff.[88][89] Overall, 303 bird species have been seen in the park since the first official list of records was published,[87] and an estimated 200 species are spotted every season.[90] No single group is responsible for tracking Central Park's bird species.[91] Some of the more famous birds include a male red-tailed hawk called Pale Male, who made his perch on an apartment building overlooking Central Park in 1991.[92][93] A mandarin duck nicknamed Mandarin Patinkin received international media attention in late 2018 and early 2019[94] due to its colorful appearance and the species' presence outside its native range in East Asia.[95] More infamously, Eugene Schieffelin released 100 imported European starlings in Central Park in 1890–1891, which led to them becoming an invasive species across North America.[96][97]
