Foraging and provisioning strategies of the light-mantled sooty albatross (LMSA) Phoebetria palpebrata were studied during chick-rearing at Bird Island, South Georgia, in January to May 2003. Virtually all trips of satellite-tracked birds were restricted to Antarctic waters. Individual birds followed a diversity of foraging routes, the majority to shelf and shelf-slope areas along the southern Scotia Arc or to oceanic waters in the mid Scotia Sea, with only a few trips extending as far south as the marginal ice zone in the Weddell Sea. Sympatric white-chinned petrels Procellaria aequinoctialis, black-browed Thalassarche melanophrys and grey-headed albatrosses T. chrysostoma also exploit these areas. Unlike LMSA, these species and the wandering albatross Diomedea exulans, also forage on the shelf and shelf-slope waters surrounding South Georgia, or at the Antarctic Polar Front (APF), where the larger albatrosses and smaller, more manoeuvrable white-chinned petrel may out-compete LMSA for access to prey. As a consequence, foraging distances and maximum ranges are greater, chick-feeding frequencies are lower and chick growth rate is slower in LMSA than in sympatric Thalassarche albatrosses, and adult LMSA appear to have little capacity to regulate provisioning according to chick condition. Nonetheless, LMSA seem well-adapted to exploitation of distant foraging grounds, apparently using the wind to reduce flight costs and, in comparison with other albatrosses, spending more of the night on the wing and returning with food loads that represent a greater proportion of adult mass.
SHIVNARINE Chanderpaul made a century to help Lancashire defy Warwickshire on day one of the day-night match.Chanderpaul’s unbeaten 117 rescued Lancashire from 55-4, Haseeb Hameed making only 17 in his final chance to impress the England selectors.The visitors were all out for 273, with Keith Barker and debutant George Panayi each taking three wickets.Warwickshire then lost opener William Porterfield to James Anderson as they closed 250 runs behind on 23-1.Porterfield’s return for only his fourth Championship appearance of the season came following Ian Westwood’s retirement from cricket on the morning of the match.The Ireland international was lbw as Anderson swung the ball under the lights, but that was down to the skill of the England man, rather than the pink ball moving any more than a red one.Anderson is looking to prove his fitness to England after a groin injury, while Hameed is searching for form before the first Test against South Africa at Lord’s next week.The opener, who has not passed 50 in first-class cricket this season, batted for more than an hour before softly driving to silly mid-off to give pace bowler Panayi (3-41) his maiden first-class wicket.That began a Lancashire slump as Alex Davies was run-out attempting a non-existent single, Jos Buttler was lbw trying to pull the off-spin of Jeetan Patel and Steven Croft was brilliantly caught at second slip by Rikki Clarke off Boyd Rankin.Chanderpaul, dropped on 49 against one of his former clubs by wicketkeeper Tim Ambrose off Patel, rebuilt with Dane Vilas (44) and Ryan McLaren (24) in stands of 96 and 68 respectively.Although left-armer Barker (3-59) got to work at the beginning of the final session, Chanderpaul completed his 76th first-class century, as he approaches his 43rd birthday.The former West Indies international looked set to take Lancashire to 300, but pace bowler Panayi mopped up the tail with the second new ball, removing Tom Bailey and Anderson with successive deliveries.
