I'm still trying to understand the diagram Lars posted.  (See below)
Reading Lars post of 7:59 AM explaining emargination as a constriction of
the margin of P6, and then the statement that Swainson's thrush has an
unemarginated (straight-edged) P6, I'm led to conclude that the diagram
represents a Hermit Thrush.

So my path was:  define emarginated, then find P6, then figure out which
species has which form of P6, then figure out which species is illustrated.
Phew!

Why couldn't you say that up front?

If you're trying to inform, don't start in the middle.  Start at the
beginning.

Thanks,

Paul Sullivan

Lars, Somebody,

You can't just post this and expect anyone to understand it.  You need to
EXPLAIN it!

Which species is illustrated?

What does emarginated mean?

Explain the numbering of primary feathers.

What does "pp covs - p10   5-4 mm" mean?

What does "p8 - p6   5-6 mm" mean?

What does "p9 <p6" mean?

This kind of post to OBOL does not illuminate the discussion of Catharus
thrushes.

Teach us, rather than snow us under.

Thanks,

Paul Sullivan

Someone took a photo on November 9,2020 that showed this lack of
emmargination on a perched SWTH, l believe in their yard in Corvallis. Sent
