ABA Photo Quiz

ABA Online Bird Photo Quiz 169

Answer

With the great comparison with what appear to be fall leaves, we can make a reasonable guess that this month’s quiz bird is quite small.  Also adding to that impression of smallness is the thin, short, all-dark bill.  The bird’s olive back and highlights to most of the wing feathers along with the grayish head permit a great reduction in the number of ID possibilities.  One might think of small flycatchers, vireos, kinglets, and warblers – nothing else really fits this beastie.

While we might want to concentrate on aspects of coloration and pattern to further our progress toward a species ID, I used this photo to highlight a structural cue that many birders seem to ignore.  This is a feature that can help us make the right call when looking at an open-country bird that one cannot decide between lark and pipit.  It is a feature that can greatly assist in identifying many perched raptors – or, at least, getting them into the right genus.  It is a feature that is de rigeur in the ID of peeps.  It is a feature that really ought to be in the ID arsenal of every birder, as it is a feature that is not subject to the vagaries of lighting or interpretation of color.  It is, except in the very rare cases of very worn or broken outer primaries or the less-rare instances of those outer primaries being in molt, a rock-solid character.  As many will have guessed/known, I discuss primary projection, which is the distance that the wingtip extends beyond the tip of the longest tertial (an incredibly useful set of 3-4 feathers per wing that is also ignored by many birders).

In the above rotated, cropped, and marked-up version of the quiz photo there are four lines, two letters, and an arrow.  If we would insist on using color patterns, that arrow is pointing to a useful character, but I will come back to that later.  The letter ‘A’ is indicating the distance between the left two lines, which is the length visible beyond the scapulars of the shortest tertial.  The next line to the right is at the tip of the longest tertial (or as close as I can get it considering the difficulties involved with the angle of the photo).  Thus, the letter ‘B’ is indicating the length of the wingtip that extends beyond that longest tertial, the primary projection.

Many small birds that inhabit shrubby habitats have little or no primary projection.  That is because if their primaries protruded beyond the tertials for any significant distance, they would be quickly abraded by extensive contact with twigs, branches, leaves, etc.  So, rather than have artificially shortened outer primaries that might also get frayed by that abrasion, they have short outer primaries.  Migration length also plays a critical part in wing length, with, generally, the longer the distance, the longer the wing.  Of course, in some species, those two forces act in opposition, with the resultant compromise being different in different species.

To get back to our quiz, the bird’s long primary projection rules out most of the Empidonax options, as only the longest-winged species have such long primary projection – Acadian and, perhaps, Alder and Willow -- and those have larger bills than our quiz bird.  Migratory vireos have fairly short to medium-length primary projection, though a few species sport projection nearly that long.  However, most of those are not in the wing-barred group and the one that is – Black-capped – has plumage features that our quiz bird lacks.  Remember that arrow?  That arrow points to another feature that rules out vireos:  the black bar below the lower wing bar that results from the olive fringes of the secondaries not extending all the way to the greater coverts (the tips of which create that wing bar).

Various and sundry plumage features – unstreaked flanks, plain back, lack of yellow plumage, long primary projection, tiny bill, short tail – rule out most or all of the Parulidae, but even those warblers that match most of these features lack that black wing bar pointed out by the arrow.  The head pattern – or lack thereof – rules out Golden-crowned Kinglet.

I took this picture of a Ruby-crowned Kinglet in Cut Bank, Glacier County, Montana, on 28 September 2015.
