Bob Flood (St. Mary’s, Isles of Scilly) has published an illustrated account in the ornithological magazine Birding on identifying ACAP-listed Atlantic Yellow-nosed Thalassarche chlororhynchos and Indian Yellow-nosed T. carteri Albatrosses.
Full-page colour paintings by John Gales of birds in flight show various stages of both species from fledgling to adult. Close-ups of birds on the water show diagnostic differences in head and bill between the two species as well as changes in age.
