Please Help Me Identify [iBird Request]

Recommended Posts

Photo was taken 08/05/18 in Manchester (Eastern), KY. I and others I have spoken to believe it to be a Northern Waterthrush, rather than a Louisiana Waterthrush, however this would be rare for the date and location (no sightings have ever been recorded on eBird for that area). This area exists well outside the Northern’s breeding range, but it’s possible it’s migrating early. iBird usually identifies it as a Northern, but occasionally as a Louisiana depending on the picture.

 Fairly positive that's a Northern Waterthrush.  The tail tapers to a pointier tip than a Louisiana's tail, which is more squared off. Also the very subtle differences in the gray wash.

This is a very cool set of photos and a good study of how iBird Photo Sleuth works, especially in showing where it can be ambiguous. However I like that you submitted several photos so you could see what answers were most likely. In your iBird screen shots it shows 99% confidence its a Northern Waterthrush for 1 of the guesses and 90% confident for the other. While for the Louisiana Waterthrush its only 69% confident. I am curious which photo gave the Louisiana as the most likely? And did you find cropping the image made any difference in which species it guessed?

I don’t know about this photo, but on my submission’s the crop makes a difference. The distance affects the results even if it’s the same photo.
