Red-throated Loon (Gavia stellata) - Digiscoped - 06 November 2012 - Portage Lake, Dexter Township, Washtenaw County, Michigan
פרטי השורה
Dec 1, 2012 - after seeing a Pacific Loon at this same location on 12/1, I am convinced that the bird seen on 11/6 was indeed a Red-throated Loon. after much discussion on the various listservs, I have moved this bird to loon sp. It is most probably a first year Red-throated Loon based on the diagnosis of others more experienced with loon plumages. It was previously reported as a Pacific Loon and I had initially placed it in that category previously reported bird - small loon with round head, gray back, neck and crown - gray on neck blends into white on throat, not sharply set off as in adult Red-throated Loon. Bill was held level not pointed upward as with Red-throated. Poor digiscoped images from ~150 hundred yards away:
