I checked ebird help for an answer to this question, but couldn't find one, so am looking to you all for help. Yesterday I was driving around Addison and saw three harriers. Or did I see one? The first time I saw one was on Gage Rd. It was a female headed NW across the open fields, beating into a fairly stiff north wind. About 10 minutes later, I was parked at the Brilyea access and another one popped up. Since it was only a little over a mile from where I saw the first one, was also a female and was NW of my first sighting, I assumed it was the same bird. About 40 minutes later, I was headed south on 125 when another female swooped over the road in front of me. I pulled over and watched it for a minute while it headed NE. This time I was about 5 miles south of the second sighting.
So my question is, do I enter this as one sighting, two sightings, or 3? Thanks for your help.
