Large Bird House, 1911.

Constructed in 1905 and designed by Heins & La Farge (the designers of the original IRT subway stations), the Large Bird House is a neo-classical structure of limestone, brick, and terra cotta. The sculpture and reliefs on the building, including the life-size eagle over the door were created by Alexander P. Proctor. Proctor, a prolific sculptor, also created pieces for three other zoo buildings, and was the artist behind the three pumas that watch over the Third Street entrance to Prospect Park. The building originally housed more than 1500 avian specimens.
