Photograph of a female passenger pigeon (Ectopistes migratorius) in captivity, 1896.
J. G. Hubbard photographed Whitman's recently acquired flock of passenger pigeons at Woods Hole, Massachusetts, in late August and early September of 1896. The two dozen images Hubbard produced, showing a nest, an egg, a young squab, as well as adults, represent the bulk of known photographs of captive (or recently shot) birds. Most of the others are photographs of Martha in the Cincinnati Zoo.
The Wisconsin Historical Society holds copies of Hubbard's photographs.
