Fellowship opportunity to help third-world seabirds

“The Seabird Restoration Program (SRP) of the National Audubon Society is seeking applicants for the Herz International Seabird Fellowship.  The fellowship is intended for biologists working with an NGO or GO from third world countries seeking experience with seabird restoration methods for applied seabird conservation. The 10-week field practicum combines ecosystem and behavior theory with practical experience from applied disciplines such as wildlife management and aviculture to develop proactive techniques for managing rare and endangered seabirds.

Recipients of the Josephine D. Herz Fellowship will begin their internship at Audubon's Hog Island Environmental Education Center (Bremen, Maine USA) on May 26, 2014 where they will take part in an intensive two day orientation program with approximately twenty-summer interns. After the orientation, the Herz Fellow will receive field experience at several managed seabird nesting islands throughout the Gulf of Maine. Instructors for the training program include biologists from Audubon's SRP and other professional seabird biologists and ecologists.”

Deadline for applications is 15 March 2014 (click here to apply).

South Atlantic male and female Sooty Shearwaters forage in different areas during pre-laying

April Hedd (Cognitive and Behavioural Ecology Program, Psychology Department, Memorial University, St. John’s, Canada) and colleagues have published open-access in PLoS ONE on differences in foraging areas by breeding male and female Sooty Shearwaters Puffinus griseus in the South Atlantic.

The paper’s abstract follows:

“Tracking technology has revolutionized knowledge of seabird movements; yet, few studies have examined sex differences in distribution and behavior of small to medium-sized, sexually-monomorphic seabirds.  Application of bird-borne geolocation-immersion loggers revealed seasonal segregation in the sexually-monomorphic Sooty Shearwater Puffinus griseus, mainly in the pre-laying period, when there were clear differences in reproductive roles.  Shearwaters first returned to the Falkland Islands on 27 Sept±8 d; males, on average, 8 d earlier than females.  Prior to egg-laying, distribution at sea, colony attendance and behaviour depended on sex.  Males foraged locally over the southern Patagonian Shelf and Burdwood Bank, spending mainly single days at sea and intervening nights in the burrow.  Females, who flew for more of the day during this time, foraged in more distant areas of the northern Patagonian Shelf and Argentine Basin that were deeper, warmer and relatively more productive.  Attendance of females at the colony was also more variable than that of males and, overall, males were present for significantly more of the pre-laying period (38 vs. 19% of time).  Sex differences were reduced following egg-laying, with males and females using similar foraging areas and making trips of similar mean duration in incubation (7.6±2.7 d) and chick-rearing (1.4±1.3 d).  Congruence continued into the non-breeding period, with both sexes showing similar patterns of activity and areas of occupancy in the NW Atlantic.  Thus, seasonal changes in reproductive roles influenced patterns of sexual segregation; this occurred only early in the season, when male Sooty Shearwaters foraged locally, returning regularly to the colony to defend (or maintain) the burrow or the mate, while females concentrated on building resources for egg development in distant and relatively more productive waters.”

Australian fishing industry association to research seabird mitigation for trawlers

Australia’s South East Trawl Fishing Industry Association (SETFIA) has received an Australian Government grant of A$360 000 to continue work on protecting seabirds from fishing boats.  The Caring for our Country grant will be used to reduce collisions that occur between seabirds and the cables used to tow trawl nets (click here).

"All trawl vessels in South East Australia and the Great Australian Bight operate with regulated Seabird Management Plans to limit interactions with seabirds.  These plans incorporate measures like managing their offal by batching or retaining it (to avoid attracting the seabirds) and using a device that protects seabirds from bumping into trawl cables.

Most vessels currently use large inflatable buoys attached to the vessel to ensure that seabirds do not collide with trawl cables.  Although the buoys are effective, they are very difficult to use, and don’t work as well, because they tangle.  So we’re keen to use the grant to develop alternative mitigation measures that are at least as effective as the buoys, but are more practical for use on trawl vessels.

The grant will be spent on trials of new methods to avoid harming seabirds, and will be monitored by scientific observers.  Observers will be used to monitor and validate the use of water sprayers as seabird deterrents.

Additional scientific observer coverage will be used to test a yet-to-be identified approach to mitigation.  Fishermen will be asked to nominate concepts for devices and a panel of experts will select a second device that will be tested.

The grant will also allow several young fishermen from South East Australia and the Great Australian Bight to travel to New Zealand to learn about New Zealand seabird mitigation measures.  We hope to that an expert from New Zealand can travel to Australia to help Australian trawl fishermen develop more methods to avoid any harm to seabirds.”

53 000 pairs of ACAP-listed Grey Petrels call Antipodes Island home

Elizabeth (Biz) Bell (Marlborough, New Zealand) and colleagues have written in the New Zealand ornithological journal Notornis on the numbers of ACAP-listed Grey Petrels Procellaria cinerea existing on Antipodes Island.

The paper’s abstract follows:

“Aspects of the breeding biology of the grey petrel (Procellaria cinerea) were studied on Antipodes Island between April and June 2001.  The island was surveyed to determine grey petrel distribution and four 2500 m2 census grids were established.  The survey suggested that the distribution of grey petrels was restricted to steep, well-draining areas dominated by Poa litorosa tussock (approximately 510 ha of the 2025 ha island).  Occupied burrow density within the 4 census grids ranged from 31 to 44 burrows (0.01 burrows per square metre).  Extrapolating from the census grid density to the total grey petrel habitat resulted in a population estimate of 114,730 birds: 53,000 breeding pairs (range = 32,000-73,000) and 8,670 non-breeding-birds (range = 4,000-16,320) were present on Antipodes Island.  Aspects of the behaviour of the species were recorded.  Comparisons are made with other members of the genus Procellaria.”
