Nikolas Haass has written a well-illustrated paper on separating juvenile Grey-headed Thalassarche chrysostoma, Black-browed T. melanophris and Campbell T. impavida Albatrosses at sea in The Petrel for 2014.
The paper’s abstract follows
“Prompted by the paucity of documented sightings of Grey-headed Albatross Thalassarche chrysostoma in Queensland and New South Wales and a series of misidentifications in several online platforms, this article aims to provide an update on the separation of juvenile and immature Grey-headed Albatross from Black-browed Th. melanophris and Campbell Albatross Th. impavida.”
