Title

Changes in Illinois's Avifauna: a Records Committee Perspective

Subject(s)

Description

The status and distribution of birdlife in Illinois is always shifting, though generally quite slowly. In the last several decades, however, birders have seen instances of very rapid changes. We’ll look at some of what is going on from the viewpoint of the Illinois Ornithological Records Committee, or IORC, by focusing on rarities. IORC maintains a “Review List” of species sufficiently rare to warrant evaluation of observational evidence of their occurrence. The stories behind movement of species on and off the Review List provide insight into how their status and distribution – or the nature of the birding community – is changing.
