We’ve had a new neighbor in our backyard the last couple of days.  He’s this little bird that flits, flits, flits — making him hard to identify.  All we could tell at first was it was blue-gray and white with a yellow patch on its head.  Finally, today he sat still long enough for us to identify him.  He’s a Yellow-Rumped Warbler.  Of the yellow-rumped warblers, there are two types:  Audubon and myrtle.  Our guy is a myrtle.  Myrtle is a tiny little bird, 4-5″ long, weighing less than an ounce.  Although they summer in the northern part of Minnesota, I don’t think I have ever seen one before.  I’d like to introduce you to Myrtle:
