So excited to come across this thread! I am fairly new at birdwatching but I love it! I discovered something this morning that I've never seen before. I had to stop what I was doing and report it on the Cornell ebird app. They do come through here (NC) during the winter months, I learned this morning, but it was new to me. I had a pair of Hooded Merganser's on my pond! I tried to take pictures but in the excitement (and nervousness due to h5n1) I only got blurry pictures that look terrible. Either way, they, especially the drake, are probably the most gorgeous wild duck I've ever seen before.
I know they're probably boring to most but I think my favorite birds to watch are American black crows and Warblers. Excited to read through this thread! I hope newbies are welcome
