“Occam’s Warbler” quiz answers

Last weel I posted a great big warbler quiz.  Below are the answers.

Bird #1: Notice the black and white all over the bird?  That’s why it’s called a Black and White Warbler.





Bird #2: The biggest ID of the Blackburnian Warbler is the bright orange/red wash on its face.

Bird #3: The Northern Parula is a fairly colorful bird, noted for its mixture of blue and yellow.

Bird #4: The Yellow Warbler is, by far, the most yellow of the warblers.  Almost entirely yellow save for a little orange/red on the chest (not always visible) and wings that are a little darker:



Bird #5: It’s easy to confuse some forms of the common yellowthroat with this bird, the Nashville Warbler  Grey head, eye ring, and yellow throat and body is its primary ID marker, but some forms of the Nashville also show a red spot on top of the head.  The biggest way to distinguish it from the yellowthroat, however, is the legs, which are black, as opposed to the lighter legs of the yellowthroat:

Bird #6: See that line across the eye and the rounded bit beneath it?  If you rotate that, you get a “P” form, which is how I remember the Prairie Warbler, a small, beautiful bird, which has a flash of white in its tail when it flies (similar to the dark-eyed junco).

Bird #7: That black mask and darker wing on an otherwise yellow bird is a primary characteristic of the Blue-Winged warbler:



Bird #8: The Northern Waterthrush is a light bird with dark, well-defined, streaks.

Bird #9: The above bird is easy to confuse with the Louisiana Waterthrush, which is like a faded out version of the Northern.

Bird #10: I think of the American Redstart as kind of like a warbler-sized oriole.  That’s not really right, but that orange and black compressed into such a tiny body makes it easy for me to remember.

Bird #11: The key factor here is that orange spot on the head of the Ovenbird:

Bird #12: That combination of the black throat and the yellow-green head can only mean black-throated-green warbler:

Bird #13: This blackpoll warbler is tricky to ID, even for experienced birders:

Bird #14: This is the fall form of the Pine Warbler.  You’ll see its Spring plumage form a little later:

Bird #15: that chestnut color on this bird’s side is a tip off that it’s a Chestnut-Sided Warbler:



Bird #16: Yellow bird, red streaks and red cap make for a fairly easy ID of a Palm Warbler.



Bird #17: Blue head, white around the eye, white eyebrow and streaking coming down from a ring around the neck with a yellow chest are classic marks for the Magnolia Warbler.



Bird #17 is easy to confuse with bird #18, but there are a few tell tale differences: eye ring vs white around/near the eye and a simple necklace rather than streaks down the chest are the marks I use.  Here’s bird #18, the Canada Warbler.

Bird #19 & #20 are all different versions of the Yellow-Rumped warbler.  To me, it reminds me of a magnolia with white on teh chest instead of yellow:





Bird #21: The color on the breast can be classified as “bay” so this is a Bay-Breasted Warbler.

Bird #22: The black throat on an otherwise dark blue bird is a defining factor of the Black-Throated Blue warbler.

Bird #23: you’ve seen this one earlier, too.  It’s the spring plumage of the Blackpoll Warbler.

Bird #24: this is the female version of one from earlier, which is a very tough ID if you’re unfamiliar with the female form of the Black-Throated Blue Warbler.

Bird #25: we see these all Summer long in Vermont.  The yellow throat and the commonness of the bird classify it as a Common Yellowthroat.

Bird #26:This is the Spring version of a Pine Warbler [my error] Yellow-throated vireo.

Bird #27: this is the non-breeding form of the Tennessee Warbler.

Bird #28: if you see a bird that looks somewhat like a yellow warbler but with a black cap, it’s a Wilson’s Warbler.:

Bird #29: this one was a shock to find– it’s a Townsend’s Warbler, which is virtually unheard of in New England, but one hung out in New Hampshire for some time last November.

Bird #30: This is the female form of the American Redstart.

As usual, treat this as an open birds & birding thread.

Thanks everyone.  Good birding!

  1. I thought you had forgotten us.

    They are all striking.

    Question: Is there a web site with the sounds / songs of birds common to this part of New England?

  2. I fail miserably at these ID games.  I have two bird books by the screen door; nevertheless I am constantly phoning a long-suffering birder friend to insist I’ve seen something completely impossible!
