At Melton Hill Park in west Knox County this morning I made history--well, personal history. I correctly identified two vireo songs and actually managed to track down the singers to confirm it, and neither vireo had eyes or throats in their names. First I heard a Warbling Vireo singing and singing and singing, so I looked and looked and looked... well, you get the idea. I finally saw leaves move near the top of a tree and found the drab little songster. In all I had two brief looks at the "warbler". A few minutes and a short distance later, I sat down at a picnic table to watch the nearby trees and soon heard another vireo. It sounded like it could be a Blue-headed but I've never been able to tell their songs reliably from red-eyed's. I soon got a quick but good look at a Blue-headed Vireo. I'm still having trouble believing it. And speaking of vireo songs, yesterday at Clark Center Park in Oak Ridge I watched a Yellow-throated Warbler doing its best to imitate a vireo. Its song was short, perhaps half a dozen notes, and all the notes clear but its sing-songy rhythm reminded me of a red-eyed or blue-headed vireo song. It sang twice and then moved along. I never would have suspected a Yellow-throated Warbler had I not watched it singing. Back to Melton Hill Park this morning, at one point I had four ospreys in sight at the same time. They circled a few times before one-by-one breaking off and flying toward the water. Walking on one of the fields, I noticed a bird fly into the trees at the back, saw red and thought I'd seen a cardinal but when I raised my binoculars I realized that the red was leaves and the bird beside the leaves was a Chat.
