Monitoring Manx Shearwaters, Arctic Fulmars and European Storm Petrels on Skokholm Island

 

The 106-ha island of Skokholm lies off the coast of Pembrokeshire in Wales.  It first operated as a bird observatory in 1933, and is currently owned and administered by The Wildlife Trust of South and West Wales.

The observatory’s seabird report for 2015 is now available.  It gives detailed information of ongoing monitoring of the island’s breeding populations of Manx Shearwaters Puffinus puffinus (the World’s third largest), Arctic Fulmars Fulmarus glacialis and European Storm Petrels Hydrobates pelagicus.

 Skokholm is a Site of Special Scientific Interest.  The surrounding waters are a marine reserve and together form part of the Pembrokeshire Coast National Park.  The island became a national nature reserve in December 2008.  Along with the nearby island of Skomer the island is an Important Bird Area designated by BirdLife International.

Update on the attack on Kaena Point’s Laysan Albatrosses: one egg survives

Following on from the news of incubating Laysan Albatrosses Phoebastria immutabilis being killed and their eggs smashed by night-time human intruder(s) at the Kaena Point colony on the Hawaiian island of Oahu on 27 December, Pacific Rim Conservation reports:

“There was a miraculous survivor of the attacks at Kaena Point - the egg pictured with the dead parent in our previous post was still alive despite being exposed and parent-less for close to two days.  We put the egg in another nest whose egg was infertile.  As of today [6 January], the egg is still alive and being incubated by its new foster parents pictured below.  While they destroyed 17 nests and an unknown number of adults, there are still 55 nests going strong.”

Authors and photographers wanted to help complete the ACAP Breeding Site Series

For the last three years ACAP Latest News has been posting illustrated articles in an occasional series that describes the many localities, most of them uninhabited islands, where ACAP-listed albatrosses, petrels and shearwaters breed around the World.  The series commenced with New Zealand’s Bounty Islands; the most recent account published, the 82nd, is for the main island in the Auckland Island Group.

For Australia, Ecuador, Mexico, Norway and South Africa all their ACAP breeding sites (including ones with now extinct colonies, such as Bouvet Island) have been written up, but for other countries hosting ACAP species, as well as for the Antarctic Continent and for disputed territories, there are still a number of sites to cover.

An appeal is made for authors and photographers to help complete the series.  Here is a partial list of the remaining sites by countries not yet assigned to volunteers:

Chile:  Isla Ildefonso
France:  Iles Apotres, Cochons, de l’Est and Pingouins in the Crozet Island Group
Japan: Mukojima, Ogasawara Islands

New Zealand:  Chatham (translocation site), Forty-Fours and Three Kings

USA: Barking Sands (Kauai), French Frigate Shoals, Gardner Pinnacles, Lisianski, Ka’ula, Necker, Niihau and Pearl & Hermes Reef
Disputed Territories: remaining individual islands in the Falkland Islands (Islas Malvinas)*, South Georgia (Islas Georgias del Sur)* and the Senkaku Islands
Antarctic Continent:  remaining colonies of Southern Giant Petrels Macronectes giganteus on and around the Antarctic Peninsula.

For a write-up what is required are:

1.  A brief description of the locality with its name, locality, size, habitat and vegetation,
2.  Information on breeding ACAP-listed species: names, numbers, trends and monitoring efforts,
3.  Conservation status: management plan, nature reserve status and alien control/eradication efforts past present or planned,
4.  Up to eight selected references, and
5.  Five to six photographs with captions showing the locality, its habitats, colonies and ACAP species.

Help is available for co-authoring and editing texts.

With thanks to the many willing helpers who have authored and co-authored breeding site accounts and submitted their photographs to date.  Hoping to hear from more!

Northern Royal Albatrosses avoid the heat with a little human help

The Northern Royal Albatrosses Diomedea sanfordi of Taiaroa Head on New Zealand’s South Island near the city of Dunedin are noteworthy in that they breed on the mainland and can be viewed by the public from the Royal Albatross Centre’s observation building.  The colony and its breeding birds are carefully managed to address such conservation issues as alien predators, fly strike and as the following account from last month shows, overheating.

“All of Dunedin's albatrosses and their incubating eggs survived Monday's [21 December] heat wave thanks to the breeze and an ingenious sprinkler system.  Taiaroa Head's 29 nesting pairs and their eggs got through the 34.6° C heat unscathed and are due to hatch on 12 January.

Department of Conservation Head Ranger Lyndon Perriman said the wind was a blessing as, on a 20° C day without wind in November, the ground temperature got up to 38° C.  This, combined with the heat of adult birds, created real problems.

The optimal incubation temperature for albatross eggs is 36.4° C, Mr Perriman said.  "The heat [on Monday] certainly didn't help.  The birds were hot but there was [sic] no major concerns.  If there's no wind and the sun is beating down, then that's when the problem comes,'' he said.

A sprinkler system had been devised about five years ago to counter the ground temperature, which was turned on manually when needed.  On Monday, the sprinklers were on, but just for one nest tucked away on the southern side of the headland out of the wind.  "We had an irrigation sprinkler going for a couple of hours,'' Mr Perriman said.  "In the past we've had birds die from heat exhaustion.  If there was no wind, it would have been absolutely diabolical out there.''

The colony started [this season] with 35 eggs, of which 32 were fertile.  Two eggs were lost due to accidental breaking by the nesting parents and the other was an embryonic death related to temperature or infection.”

Last season a total of 32 eggs was laid, resulting in 27 chicks fledging.

Suburban Laysan Albatrosses on Kauai are settled in for the new season

Laysan Albatrosses Phoebastria immutabilis breed at a number of coastal localities on the Hawaiian island of Kauai as has been reported in the ACAP Breeding Sites series.  One of the most unusual perhaps is within the suburb of Princeville where birds breed in private gardens and on golf courses.  Most Princeville albatrosses are colour-banded and dedicated “civilian scientists” Cathy Granholm and Bob Waid have been monitoring and reporting on the breeding attempts from nest construction though egg laying and chick rearing to fledging since at least 2011.

This season eggs were first reported laid in Princeville on 24 November, with the first birds arriving from around the 10th (click here).  Follow Cathy’s and Bob’s websites to see how the Princeville Laysans fare this season (and check out previous years).

An “Albatross Cam” directed at a Kauai Laysan Albatross nest is expected to go live in a few weeks for the new season.
