Proposal (#88) to South American Check-list Committee:

Split Hylocharis grayi into two species: H. 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 Panamá 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. Los diferencias marcadas por Gary, especialmente medidas y colores, son convincentes."
