There were a few notes posted in past here about a color of Boat-tailed Grackle eyes. Here is one Boat-tailed with very dark iris; found in Quintana - September 15, 2012 on the beach. I do not recall ever seeing another one with darker iris, or even close to. In the field eyes seemed to look solid black. In photo iris look little lighter than pupil. I checked a lot of photos posted on the Internet (I was surprised how many Great-tailed are Ided as Boat-tailed) and mine seem to have possibly one of the darkest iris but perhaps some people had seen even darken than that - any photos available to check? I do not have any particular interest in this species but maybe somebody else like to see this example for comparison. _http://www.pbase.com/image/146241169_ (http://www.pbase.com/image/146241169) Mark B Bartosik Houston, Texas _http://www.pbase.com/mbb/from_the_field_ (http://www.pbase.com/mbb/from_the_field)
