Hello,
Yesterday I was walking my usual morning bird watching trail in my neighborhood hoping to catch some migrating birds as the migration is winding down. Early on in my walk I spotted a Tennessee Warbler, which is a great find for my neighborhood. Over the last few years, I might see a Tennessee Warbler once or twice a year in this neighborhood, usually in the fall. I spotted that one and continued on my walk and saw some other good birds. About an hour later I noticed some movement in a row of trees along a road near one of our ponds. The previous fall I has seen some warblers in those trees and had been keeping an eye on them every time I walked by. I found several different bird species in the trees, including two more Tennessee Warblers. I was surprised to find two more and I managed to get a decent photo of one of them before they disappeared on me.
I knew that I had seen Tennessee Warblers in that same tree last year and when I got home I went into eBird and went back to last Octobers observations. I discovered that I saw two Tennessee Warblers on the exact same date last year. Considering that I seldom see Tennessee Warbler in this area, I was a bit amazed that I had seen them on the same date, a year apart in the same tree. Is this just a coincidence? Not that I think they are the same birds, but it's a funny thing.
