The Passenger Pigeon (Ectopistes migratorius) was a social breeder and it has been suggested that the species experienced functional extinction, defined as a total reproductive failure, prior to its actual extinction in the early years of the 20th century. Here, we apply a novel statistical method to a record of egg specimens and so-called skin specimens to test for functional extinction. The results indicate that the species did not become functionally extinct, suggesting that proposals to reverse its rapid decline in the late 19th century could have been successful.
