Mr Sigman's (Zapata) Sparrow (1 Viewer)

Here´s a possible (!) addition on ...

sigmani as in:
• the subspecies Torreornis inexpectata sigmani (here) SPENCE & SMITH 1961:
This new subspecies honors the late Arthur Tucker Sigman of Elverson, Pennsylvania; this kindly gentleman was an inspirational teacher, conservationist,and amateur ornithologist.
... which ought to be; Arthur Sigman (1892–1959), whose full name (as stated in the OD) was Arthur Tucker Sigman, US teacher, Scoutmaster, conservationist, birdwatcher, member of the Elverson Garden Club, etc., etc.

Disclaimer: The Birth year was only found here, in the "Local Historian Index-A" (for Tri-County Heritage Society). Looks like a reference to some kind of Paper/Presentation (made in 1995) ... which I haven´t checked/found.

Thereby; take it for what it´s worth!

Mr. Spence describe the subspecies in a local bird club publication. But "the paper is
mimeographed, it does not constitute a valid description" Is that true in this epublished future?
