The ibis population has grown very large at Audubon park over the last few years. I'm not sure that I saw many at this location before 3 years ago.

I am adding a record of the Ibis in the same scanned slide.
The family Threskiornithidae includes 34 species of large wading birds. The family has been traditionally classified into two subfamilies, the ibises and the spoonbills; however recent genetic studies are casting doubt on the arrangement, and revealing the spoonbills to be nested within the old world ibises, and the new world ibises as an early offshoot.
