The bird list describes your chances of finding various birds in the Greater Cincinnati area. The list covers the area that Cincinnati birders might visit in the course of a long morning trip. This is a rather vaguely defined range; think of it as the Birdathon area, or 75 miles from downtown if you don’t know what the Birdathon area is.
This is not a complete list of all birds which have ever been seen here. Only species which occur regularly have been listed. The finding codes indicate the chances of seeing or hearing a particular bird during a morning of solid birding. This is not quite the same as describing how common the bird is. The codes presume that the observer is experienced and is in the right habitat. They relate to a “normal” year, if there is such a thing. Many birds vary in their abundance from year to year, sometimes to a considerable degree.
The bird list also forms the basis for a daily checklist. This checklist is customized for the day of the year, showing only those species which can reasonably be expected to be present on that day. The daily checklist can be printed for use in the field.
