Orange-crowned Warblers are never as plentiful in my yard as the other two winter warblers, the Yellow-rumped and the ever-present Pine. Some years, like last winter, they never show up at all, but this year has been different. They still don't show up in pairs or small groups like the Pine Warbler or in somewhat larger flocks like the Yellow-rumped, but there is at least one that now shows up regularly at my feeders.
The Orange-crowned is a very active little bird, always flitting about, and is great fun to watch. He will always be a welcome visitor in my yard.
