Although it was one of the smaller dioramas at the Academy of Natural Sciences, the tragic history it illustrated was on a massive scale: "There is nowhere on Earth today that humans can hear the roar of an approaching flock of passenger pigeons and see the light fade as they block out the sun, but the birds in the diorama offer a portal."
A flock of passenger pigeons rests frozen in time on the third floor of the Academy of Natural Sciences of Drexel University. The birds feed on the ground, rest on twigs and raise their wings to take to the air in a beech forest whose colonnade of gray trunks recedes into the diorama’s painted background. The mounted skeletons in Dinosaur Hall help visitors picture a T. rex treading the earth, a predator with no contemporary counterpart. The same is true of this display for the extinct passenger pigeons that once flew in the billions.
“The Pidgeons in such numbers we see fly, that like a cloud they do make dark the sky; and in such multitudes are sometimes found, as that they cover both trees and ground,” says Keith Russell, program manager for urban conservation at Audubon Mid-Atlantic, quoting early Pennsylvania settler and poet John Holme. Russell says that thanks to centuries of written accounts, as well as Philadelphia’s role as a hub for natural history exploration, “there is a longer timeline of records for Philadelphia than there is for any other place.”
Hannah Michelle Brower and Aspen Simone of Philly Pigeon Tours highlighted that connection in a special program they offered for the nation’s 250th. The tours usually focus on urban pigeons (aka rock doves), free-flying members of a domesticated Eurasian species. “We talked about the rock pigeon and the history with them, but focused more on passenger pigeons because they were native to America,” Brower says. “We talked about the whole history of early colonist records of their abundance and how people caused their decline and extinction.”
