At this point (if this bird was included in my MS, which it isn't), from what we've seen this far, I wouldn't dare to say more than the following, regarding the guy commemorated in ...
• the Guira Tanager ssp. Hemithraupis guira fosteri
SHARPE 1905 (OD in post #1), as "Nemosia fosteri
= the (most likely British) collector (allegedly, originally a Sailor?) William Foster
(†1915), who, arrived in Paraguay in 1894, where he settled down (and opened a shop) in Sapucái, [onwards a k a Guillermo Foster
(alt. ditto Fórster
)], from where he delivered various Naturalia
(Birds, Mammals, Reptiles, etc., etc.) to different museums on various continents [at least to the United States National Museum
, in Washington, D.C., USA, and the British Museum
(todays BNHM, British Natural History Museum
), UK, as well as the Museo Nacional de Buenos Aires
, Argentina (today's Museo Nacional de Ciencias Naturales "Bernardino Rivadavia"
He apparently also established "his own", more modest, museum; the (no longer existing) Museo de Historia Natural
, at (de la Escuela Normal de
), in Asunción, Paraguay (at a local School?). Collector of the Type 31 March, 1904 [verified; here
]: "Collected by and purchased of W. Foster", and onwards ... until he died, the 17th of March 1915, in the same Sapucái (alt. Sapucay, in English), a small town in the departament of Paraguari (located some 80-90 km East Southeast of the capital Asunción).
This far I haven't seen anything pointing in favour of "1867" or "1873" (as his Birth year). Could be either one. Or not. And no sight (absolutely nothing) of the missing "T." ... !?
For what it is worth.
PS. "His" Tanager is also listed as "Hemithraupis Fosteri
(SHARPE)", by Dabbene 1914, (here
PPS. And beware
(if googling/searching for him); there seems to have been some other guys by the name "Guillermo Foster
" (adapted, or not), in various parts of South America, in about the same Era (see for example, this
earlier 'namesake'), some mentioned as "norteamericano
", others of unclear Origin.
