Seabird assemblages in Antarctica’s Drake Passage

Michael Force (Antarctic Ecosystem Research Division, NOAA Southwest Fisheries Science Center, La Jolla, California, USA) and colleagues have published in the journal Polar Biology on seabirds, including ACAP-listed albatrosses and petrels, in the Drake Passage between South America and the Antarctic Peninsula.

The paper’s abstract follows:

“Drake Passage, extending from the southern tip of South America to the northern Antarctic Peninsula, is a dynamic oceanographic region with well-defined habitats delineated by the three strong frontal jets of the Antarctic Circumpolar Current (ACC).  Here, we describe seabird species distribution patterns across Drake Passage and test the hypothesis that species assemblages broadly reflect physical characteristics of the hydrographic fronts.  Strip-transect seabird surveys were conducted between Tierra del Fuego and the South Shetland Islands (700 km track line) during January–March (austral summer) over 14 years (48 crossings).  Locations of the latitudinally variable fronts were assessed using in situ shipboard data on sea surface temperature and salinity; areas of high variance were used to indicate frontal features.  We quantified five distinct species assemblages that correspond to biogeographic regions and relate to the positions of the Sub-Antarctic Front, Polar Front and ACC Southern Front.  Dense seabird concentrations coincided with regions characterized by highly variable sea surface temperature and salinity, suggesting that associated species assemblages reflect the mesoscale hydrographic surface as indicated by sea surface conditions.”

Twenty-seven-year-old Northern Royal Albatross pair at Taiaroa Head incubates its 10th egg

‘Green Blue Red’ and ‘Yellow Blue Orange’ are currently the oldest Northern Royal Albatrosses Diomedea sanfordi on view from the observatory at the Royal Albatross Centre on Taiaroa Head near Dunedin, New Zealand (click here).

The paired birds have constructed their nest for the 2014/15 breeding season and are currently incubating their 10th egg, of which seven have been successful.  At 27 years, they are the oldest pair of Northern Royal Albatrosses on view and have set-up their nest on the Quarry Track in exactly the same place as where they successfully raised a chick in the 2012/13 season.

 

The 27-year old paired birds at their nest

Their previous chick fledged with an insufficient amount of wind behind, causing it to crash land just off the coast of Taiaroa Head.  A Department of Conservation ranger was luckily on hand to pick the fledgling out of the surf to safety in his boat before a more successful take-off later in the day.

Tairaoa Head was once the home of the World’s then oldest known albatross, Grandma, who reached an estimated 60 years (click here).  The late Grandma has now been surpassed in the extreme age stakes by Wisdom, a well-known Laysan Albatross Phoebastria immutabilis on Midway Atoll, now breeding once more in what is thought to be her 64th year (click here).

Plans to control Norfolk Island’s rats and cats set to help both parrots and shearwaters

The Australian Government’s Threatened Species Commissioner has made AUD 300 000 available to expand rodent control (which commenced in 1992) in and outside of Norfolk Island National Park on Norfolk Island in the Pacific Ocean (click here).  This action is set to help protect the endemic Norfolk Island Green Parrot Cyanoramphus cookii which has declined in numbers to no more than a couple of hundred individuals, now largely restricted to the island’s national park and adjacent forested areas and orchards (click here).  Predation by feral Domestic Cats Felis catus and Black Rattus rattus and Polynesian R. exulans Rats are considered causative factors in the decline.  House Mice Mus musculus are also present.

The “funding will enhance the rat baiting program across Norfolk Island National Park and expand it beyond the park’s borders.  This will complement work to tackle feral cats [trapping of cats started in1989 within the park] and substantially reduce direct and indirect impacts of rats on native species and their habitats. The project will:

  • increase the number of rodent bait stations across Norfolk Island National Park, including filling gaps in the park’s existing rat baiting network
  • expand the existing network of bait stations to incorporate part of the bordering forestry reserve
  • establish a program of ongoing servicing and monitoring to cover the expanded bait station network.”

The enhanced control programme is expected to help the island’s ground-nesting seabirds, including the Wedge-tailed Shearwater Puffinus pacificus with “several hundred thousand” reported in 1981 to be present.  However, the island’s population is thought to have declined significantly since the 1980s due to attacks by feral cats.

Little Shearwaters P. assimilis (of the nominate race) were present at Anson Point on Norfolk Island in the 1970s but breeding is now confined to the much smaller and predator-free Phillip and Nepean Islands in the Norfolk Island group (where Wedge-tailed Shearwaters also breed).  According to the latest edition of the Australian Action Plan for Birds their disappearance from the main island is thought due to depredation by the island’s rats.  Flesh-footed Shearwaters P. carnepeis are also thought to breed on Phillip Island in small numbers.  In addition, three species of Pterodroma petrels breed on Phillip Island.

Norfolk Island (35 km2) is an external territory of the Commonwealth of Australia.  It has a human population of 2300.  The 6.5-km²forested Norfolk Island National Park centred on Mount Pitt was declared in 1985; it includes Phillip Island (added in 1996).

ACAP Breeding Site No. 75. North-east Kauai, where Laysan Albatrosses breed on private lands - and a webcam has made one pair and its chick famous with two million hits

Kauai, one of the USA’s inhabited Hawaiian Islands in the North Pacific, supports several populations of Laysan Albatrosses Phoebastria immutabilis.  Although small, these populations are considered significant because their height puts them above predicted sea-level rises which are thought will seriously impact the much larger Laysan Albatrosses populations on the low-lying North Western Hawaiian islands.  The Kauai albatrosses differ in their levels of protection and management, so are here treated as four separate populations.

The North-east Kauai and Princeville populations are marked in green

Around 130 pairs breed within the Kilauea Point National Wildlife Refuge, although they are not readily visible to the public.  Secure breeding opportunity within this refuge has recently been expanded by the building of a predator-proof fence.

Farther west on the island approximately 40 pairs breed within the community of Princeville where they are studied and protected by concerned inhabitants (click here)

Over 80 pairs attempt to breed annually on the south-west shore of Kauai within the US Navy’s Pacific Missile Range Facility Barking Sands (click here).  Because these birds are a collision hazard to aircraft their eggs are removed each year; some of which have been given to foster parents elsewhere on the island as a conservation measure (click here).

In addition to these three separate populations, Laysan Albatrosses breed on private lands along the north-east coast of Kauai, in a 16-km stretch from Princeville to Anahola, east of Kilauea Point.

Four well-fenced spots occur in this coastal region where the birds are well protected but in unfenced sections breeding Laysans are at risk to domestic dogs Canis familiaris that are allowed to roam loose, with 25 adult birds known to have been killed by dogs in the 2012/13 breeding season.  Hawaiian Department of Land and Natural Resources staff then went door-to-door in the neighbourhood and the killings stopped.  Live traps have been used on unfenced properties to catch the most problematic dogs.  Feral cats Felis catus are also deemed to be a problem and control activities take place by volunteers of the Kaua‘i Albatross Network.

The combined total of the Princeville to Anahola private properties saw 59 chicks fledge from 87 eggs laid (of which 68 hatched) in the 2013/2014 breeding season.  Some 10-25% of the breeding birds are female-female pairs which lay double clutches (click here), giving opportunities for cross-fostering with eggs from Barking Sands, as has happened recently in the privately-owned Na Aina Kai Botanical Gardens.  Non-breeding birds caught and banded at Barking Sands have also been released in the botanical gardens for some years, some of which have commenced to breed.  In the past translocated birds were released within the Kilauea Point National Wildlife Refuge but this apparently no longer occurs.

An incubating Laysan Albatross

A live-streaming remote camera operated by the Cornell Laboratory of Ornithology set up on a secure property in north-east Kauai went live on 27 January this year.  Over the next five months until the chick (named "Kaloakulua", which refers to a phase of the moon when it hatched) successfully fledged in late June the “TrossCam” received nearly two million hits from 195 countries, with regular write-ups being posted.  One notable event was when a stray dog showed up a few metres from the chick, fortunately without harming it (click here).  The dog was later live-trapped and adopted.

It is intended to use the camera at a nearby nest site in the 2014/15 season now that egg-laying has commenced.

Global Positioning System (GPS) tags were placed on 12 adult birds in the Na Aina Kai Botanical Gardens this year as part of a collaborative study of the at-sea movements of several Hawaiian seabird species by Pacific Rim Conservation, Oikonos Ecosystem Knowledge and the U.S. Geological Survey’s Western Ecological Research Center (WERC-USGS).  The birds have been tracked at sea for up to 79 days (click here).  In addition, Kaloakulua received an archival geolocator tag before fledging in the hope it could be recovered for downloading when it returns to land after its first few years at sea as a juvenile.
