Hannum's Masked Tityra (1 Viewer)

Here´s a possible, at least plausible addition/question on …

hannumi as in:
● the subspecies Tityra semifasciata hannumi VAN ROSSEM & HACHISUKA 1937 (here):

Continuation of our studies on birds of northwestern Mexico, particularly those recently collected by van Rossem and Hannum for the Dickey, Hachisuka, and Sheffler collections, … […] …collected by A. J. van Rossem and Robert Hannum.

In today's HBW Alive Key explained as:

hannumi
Robert G. Hannum (fl. 1939) US zoologist, collector in Mexico (subsp. Tityra semifasciata).

Could it be Robert Gillette Hannum (1918–1989), of California, later US Customs, inspector of foreign birds and mammals ... ?!?

Born on February 15, 1918 … died 27 February 1989.

See the following links: "recent deaths" (November 1989), here, p. 891, also noted as "the late Robert G. Hannum" (in February 1990), here, p.127.

Disclaimer: no obvious connection found, neither to Mexico nor to field collections of any Naturalia!

Note that, this far, I might, could have the wrong years? It could be another, different Robert (G.) Hannum all together, but I don´t think so ...

Anyone know? If it´s him? Or not?

Two tiny tidbits that might help lead to some details about the collector in Mexico:

"Robert Hannum" collecting in Sonora with van Rossem, 1937: https://sora.unm.edu/sites/default/files/journals/condor/v040n05/p0226-p0227.pdf (green kingfisher, bottom of second page)

"Robert G. Hannum" still alive in 1951, or close to it: https://sora.unm.edu/sites/default/files/journals/condor/v053n04/p0161-p0177.pdf (thanked on page 162)

Thanks, "natreb" ... yes, also here in 1937 (p.158). And here is he (?) listed in 1939 ... and onwards.

The one thing that worries me is this note (here p.96), from MINUTES OF COOPER CLUB, ... of December 1934 : "The application of Mr. Robert G. Hannum, 3634 Hughes Avenue, Palms, California, proposed by Mr. George G. Cantwell, was presented."

If born in 1918 he sure started out young!

At least his name was here Hannum, Robert Gillette p. 178

The Eponym Dictionary of Birds claims:

Masked Tityra ssp. Tityra semifasciata hannumi Van Rossem & Hachisuka, 1937
Robert G. Hannum (fl.1959) was an American zoologist who worked at the Western Foundation of of Vertebrate Zoology, Los Angeles, and collected the holotype with Van Rossem in Mexico (1937). He was an inspector for the Bureau of Biological Survey (1939).
