I wanted to make a notation about the number of wood warblers I have noticed in the past week. There are always many spring warblers around here...I have come to know them by their markings and even their song. It is nice to work in the garden and hear them singing, and notice the voice of a new summer arrival. This is not so easy with the wood warblers. They are not as colorful, and usually we do not seem to have many passing through. However, this fall is markedly different. I have noticed many of them feeding around the riverrim, and the air is filled with song. I am frustrated when I hear the beautiful and sometimes complex song of a bird that I cannot identify. It is difficult to identify a bird purely by it song. I have read several books on the subject, and even resorted to listening to Petersons (Birding by Ear). I think I will have to get something that deals specifically with Wood Warblers.
