The Warbler Guide to Aging and Sexing Sheet

Tom Stephenson and Scott Whittle, authors of The Warbler Guide, have a reputation for presenting information to their readers in new and helpful ways. This includes looking at birding in the field as realistically as possible while teaching people to not just look for the same obvious features every time when trying to identify a bird. Taking it to another level, the two have a sheet designed to help birders determine the age and sex of the warbler they are viewing:

This species is a very vocal singer, has many variations, and is often confused with other species, especially from the distance. This one Section song could be Common Yellowthroat, Kentucky Warbler or even Carolina Wren. Which is it?

Solution for Week Two Migration Quiz Monday

OUR QUIZ BIRD

Let’s look at the Warbler Guide Finders to narrow this one down.  There are a number of birds with yellow in them…let’s see if there are any other features we can find that will help us narrow it down.

bir

THE FINDERS SHOW A NUMBER OF YELLOW BIRDS – WHAT ELSE CAN WE LOOK FOR?

Let’s work from head to tail … on the head we see a pronounced supercillium (eyebrow)…that should be helpful!  There’s a tinge of brown on the crown, too.  The upperparts of the back are brownish – and look at those wings…there are wingbars but they’re brown, which might be another useful point.  The underparts are patchy yellow, and the rump and undertail are yellow (brighter in the undertail).
bird

SOME USEFUL MARKS INCLUDE A WIDE SUPERCILLIUM, BROWN IN THE CROWN AND WINGS, BROWNISH WING BARS, PATCHY YELLOW IN THE BODY, AND A YELLOW RUMP AND UNDERTAIL.

So let’s look again at the finders…there really aren’t that many birds that are drabish yellow with a strong supercillium.  I see Palm, Prairie, Hooded, Tennessee, Orange-crowned, Blackburnian, Worm-eating, Swainsons, Blackpoll, and Yellow-rumped (Myrtle).  Out of those, which have yellow in the body or undertail?  Just Palm, Prairie, Hooded, Orange-crowned and maybe Blackpoll.  Great!  We’re really narrowing it down now.

biiii

ONLY A FEW SPECIES HAVE A SUPERCILLIUM AND ARE DRABISH-YELLOW LIKE OUR QUIZ BIRD.

Here’s something else, though…what about those brown wingbars?  And the yellow upper and undertail?  Really, that only looks like Palm as far as I can see.  If I go to the Palm Warbler account, I see that in fact those are a unique combo…and combined with tail-pumping, this looks like a really good match.

OUR PALM WARBLER COMPARISON PAGE CONFIRMS THE ID.
The only thing close is Prairie…but look how the wingabars are yellow, not brown, the streaking is black as opposed to reddish-brown, and the Prairie has a distinct facial pattern that is different from Palm.  It is, in fact, a fall Palm Warbler.  These birds are often seen feeding on the ground, and also in small flocks.  Their continuous tail-pumping is a great tip-off, too, and although there are some other tail-pumping warblers (the Waterthrushes, Magnolia, Prairie and Kirtland).  the flocking, yellow undertail and rump, brownish wingbars (and often crown) and sometimes brown breast streaks are all separators.

Fall Warbler Sighting!

Scott Whittle and Tom Stephenson, authors of The Warbler Guide, are busy all month with events (see here), but that won’t stop us from keeping their awesome warbler images coming!

The photo below from The Warbler Guide is of a female Black-and-white Warbler in the fall, snapped by none other than Scott Whittle himself. And don’t worry, we promise the bird is upside down, not your computer!

Upcoming Warbler Events

Stephenson_WarblerGLooking for more opportunities to get a little bird-brained? So are Scott Whittle and Tom Stephenson, authors of The Warbler Guide! As November rapidly approaches, the two are gearing up for their next two appearances.

For their first event, this dynamic duo will be speaking at the NYSOA 66th Annual Meeting and New York Birders Conference, which will take place November 1-3. Hurry though! Online registration ends October 27th. You can register here.

The conference will feature:

  • Exciting speakers on birding and bird conservation, including Tom Stephenson and Scott Whittle
  • Field trips with top birders to great local destinations
  • A banquet dinner featuring a program by James Currie of Birding Adventures TV
  • Photography and digiscoping field workshops
  • Posters and vendor tables including major optics manufacturers
  • Workshops and student papers
  • Great shopping nearby and an excursion to Manhattan for non-birding guests
  • NYSOA’s Annual Business Meeting and award presentations
  • Plenty of time for socializing

P1020402aThe second event, in which Scott Whittle will be flying solo, is the 20th Annual Rio Grande Valley Birding Festival, which will take place from November 6-10. Online registration ends October 25th so to register now, click here. According to their website, Scott Whittle will be there to conduct a ‘warbler workshop’. It is described as such:

“[Scott will] go over their new system of identification that uses the views that you actually get, not the idealized views that happen so infrequently. Learn how just a little more attention to detail, coupled with knowledge of habitat, behavior and special points like color impressions can lead to greatly improved identification ability. Also covered will be their in-depth analysis of warbler vocalizations, an extremely effective tool for truly understanding and remembering birdsong. Join Scott and bring your warbler skills up to the next level!”

Fall Warblers

For guys like Scott Whittle and Tom Stephenson, authors of The Warbler Guide, spotting a warbler and snapping a picture is an exciting moment, and for those of us who stepped on a twig and scared that bird off long before we got out our iPhone, we’re just glad someone else is able to get the job done.

The photo below from The Warbler Guide is of a male Common Yellowthroat in the fall.

Migration Quiz Monday: Week Two!

Ready for round two? It’s the second Migration Quiz Monday and this time we’re got a picture of a bird that we need help identifying, along with a couple distinguishing features. Have a guess? Comment below and check back later this week for the answer!


Visual Quiz: Bird on the Ground

PALWAR101009_33T.jpg

A mystery bird in Prospect Park, Brooklyn.

This is a bird we found walking around Prospect Park in Brooklyn in the fall.   It’s a drab yellowish warbler that’s feeding along the edge of a park meadow, picking insects off the ground and low branches, and it seems to be pumping its tail regularly.  What is it?

The Mystery Trill: Solution!

Recently posted on TheWarblerGuide.com as well, here is the answer to the mystery trill question posted earlier this week!
Plus don’t forget to check back here next week for our next Migration Quiz Monday!


Audio Question: Trills Answer

This song obviously has two different Sections. The first has 8 Elements. Although they are fairly fast, they are slow enough to be very distinct and it’s possible to imagine counting the number while it’s singing. The Elements are somewhat emphatic and bright, as they are Expanded and cover a large frequency range.

The second Section is lower, and way too fast to count; a trill. The pitch is fairly stable during both Sections.

It turns out this speed difference between the first and second Sections is an important clue.  Let’s first examine Orange-crowned Warbler’s song.

ORCWAR_121108#08-2

Many Orange-crowned songs have a similar form: 2 Sections, the second lower. However the speed is much different. Both Sections are so fast that it would be impossible to imagine counting the number of Elements. This characteristic: that all Sections of this species’ songs are sung at trill speed is a very good ID point.

Also, the pitch tends to drift and, in general, the Elements are less Expanded and thus less emphatic.

Based on these characteristics we can rule out Orange-crowned.

Nashville also has a similar song form: 2 Sections, the second lower.

NASWAR100425_07

However Nashville’s first Sections are quite different. Instead of short, fairly emphatic 1-Element Phrases, Nashville’s songs are almost always 2-Element Phrases. And the Phrase speed is considerably slower. This more deliberate speed, with 2-Element Phrases, makes it easy to separate Nashville from this song.

That leaves Wilson’s Warbler. Wilson sings a fairly wide range of songs. Many are only 1-Section, often falling in pitch towards the end. They also sing 2-Section songs like our target song.

WILWAR_102107#03-2

The key point is that the first Sections are fairly emphatic Phrases that are never fast enough to be a Trill. And although they can be somewhat intricate, the Phrases are never made up of 2 separate, repeated Elements.
