Similar species and how
were they eliminated:
White-faced Ibis is the only really similar species, and was present for direct comparison. This bird had dark slaty-gray facial skin surrounded by a thin border of pale bluish-white facial skin. There were no white feathers bordering the facial skin. The pale border did not reach behind the eye. The eye was dark, blackish. The legs were grayer than adjacent White-faced Ibis, with reddish at the "knees" (intertarsal joints) but not away from the joints. Hybrids were eliminated because the facial skin was solidly dark slaty gray with no indication of reddish or purple, and eye was completely dark. See photos for further details.
Previous experience with
this & similar species:
Quite familiar with White-faced Ibis, typically hundreds observed each week in breeding season in Utah. I have seen Glossy Ibis on several occasions in Utah and elsewhere. This is my seventh observation of the species in Utah (see records 2008-14, 2013-38 [two birds], 2013-45, 2013-46, and 2013-47). I have also seen hybrid Plegadis on several occasions in Utah.
