Proposal (88) to South American Classification Committee:
Split Hylocharis grayi into two species
Hylocharis
grayi (Pacific foothills and drier valleys of Andean Pacific slope
in Colombia and N Ecuador) and H. humboldtii (mangroves and adjacent
lowlands along Pacific coast from extreme SE Panama to N Ecuador). The two
differ in habit, elevation, coloration (especially males) and measurements (not
only size but proportions). They were considered separate species for over half
a century following their descriptions, until Peters lumped them without
explanation - possibly misled by untrustworthy distributional data. The
arguments are set forth in more detail in my note in Ornitología Colombiana 1:71-73
(see www.ornitologiacolombiana.org). I might note that Ridgely & Greenfield
also split them, but got some of the plumage details mixed up and did not
present a morphometric analysis.

Comments
from Zimmer: "YES, especially since this is un-doing an unjustified
Peters lump."
Comments
from Jaramillo: "YES. Seems like a clear one based on plumage differences,
habitat differences, measurements etc. Also, given that the original lump was
based on no known data, this certainly repairs a poor decision."
Comments
from Nores: "YES. Si estoy de
acuerdo en separar Hylocharis humboldtii de H. grayi. Las
diferencias marcadas por Gary, especialmente medidas y colores, son
convincentes."
