Leg 1, Day 13
After leaving Ile de la Possession yesterday evening, we headed for Kerguelen with a following sea and a cold 20-25 knot wind. Bird diversity was relatively poor, with prions, White-chinned Petrels and Wandering Albatrosses being the most conspicuous species throughout the day. Salvin’s and Antarctic Prions were equally abundant until mid-afternoon, when the latter started to dominate, and a few Slender-billed Prions were photographed. This gradual change makes sense given that Salvin’s Prions are restricted to the Prince Edwards and Crozets, Antarctic Prions occur in small numbers at the Crozets but are abundant at Kerguelen, and Slender-billed Prions are only found at Kerguelen in the Indian Ocean sector. A couple of Southern Royal Albatrosses circled the ship repeatedly among the more numerous Wandering Albatrosses, for once being reasonably friendly. A Fin Whale was seen briefly before breakfast; the only other cetacean sighting was a blow spotted by Dominic before lunch.
