International Migratory Bird Day Event Canceled

The International Migratory Bird Day Event planned for May 12, 2012 has been canceled due to nesting osprey (Pandion haliaetus) adjacent to the refuge auto tour loop near the cross dike pump station. The osprey is classified as an endangered species by the State of Illinois, thus requiring an added level of protection.

This is the first known osprey to nest on Chautauqua National Wildlife Refuge. The ospreys generally incubate 2 to 4 eggs, with the eggs generally hatching in 36 to 42 days. One to three young can be expected to first leave the nest (fledge) in 50 to 55 days after hatching. The nest may be fiercely defended by the adults, possibly striking a person if they approach the nest. The female generally handles most of the incubation while the male brings food, nearly exclusively fish, to her on the nest. If properly protected, this pair of birds may return to this nest for multiple years.

A 330 ft. perimeter of the nest has been closed to provide sanctuary for the nesting pair.
