black-eared hemispingus - IOC - what's the deal? (1 Viewer)

James Lowther

Well-known member
Hello,
IOC recognises a three way split of black-eared hemispingus into black-eared (melanotis), western (ochraceus) and piura (piurae).

Most info on this proposed split that i can find indicates that black-eared sensu stricto would include all pops from the east slope of the andes, with western covering northerly west slope pops in ecuador and colombia and piura covering more southerly west slope pops in peru

e.g.

Ridgely and Tudor, Field Guide to the Songbirds of South America: The Passerines

however looking at the distributions on the IOC spreadsheets seems to indicate that east slope susbspecies from peru and bolivia (castaneicollis & berlepschi) are included with western hemispingus (range w Colombia to c Bolivia) rather than black-eared (range sw Venezuela to e Ecuador)

so what's the deal?

is this a mistake/oversight or do they split up the subspecies differently from e.g. Ridgley and Tudor

cheers,
James
 
You're absolutely correct; the IOC ranges need to be revised. They should be as follows:
Black-eared Hemispingus (polytypic): sw Venezuela to wc Bolivia.
Western Hemispingus (monotypic): sw Colombia, w Ecuador
Piura Hemispingus (monotypic):sw Ecuador, nw Peru

Thanks for catching this.
