Sunbird Species by Elevation

Caption

A striking feature is that closely related species often lie in different elevational zones: this appears to be last niche dimension along which species have diverged. That is illustrated here for three species of sunbirds (2 other species are not shown). Left, from top: Aethopyga ignicauda (photo by Biswapriya Rahut, Jalpaiguri), Aethopyga nipalensis (Clement Francis), Aethopyga siparaja (S. K. Yathin, under the GNU documentation license).
