I have had a steady trickle of warblers, over the past two weeks. Black-throated Green, Blackpoll, Black and White, Tennessee, Yellow-rumped and Cape May Warblers have been present. Ruby-crowned Kinglets showed up on Saturday. For some reason, I had several Scarlet Tanagers; which I had not seen all Summer.
It is prime time to get out the binoculars and take a leisurely stroll through the countryside. Enjoy the fall colors and hopefully encounter a bird; which you have never seen before. You never know what may show up. Go out a search out that song you have never heard before; it may be something good.
