Yellow-rumped Warblers are arriving on the Mendonoma coast to spend the winter here. Their song can be heard from trees. I learned on the Cornell Lab of Ornithology website that they are the only warbler that can digest the wax of the berries of Wax Myrtle and Bayberries.

Here's a link to their site where you can hear their sweet call.

Craig Tooley has photographed this small songbird several times and has kindly allowed me to share them with you here.
