I did an analysis of 8339 reports of Eurasian Collared-Dove from 1996 to 2017 seen in the central Oaks & Prairies (21 counties). It shows average count per sighting of 3. During those years it varies significantly from an average of 1.7 to 4.1 per sighting. However, if the reports are lumped in 5-year blocks, it shows increases until about 2011 and a slight drop-off thereafter.
