Portraits & Profiles - Buller's Albatross

The Southern Ocean, including around New Zealand and southern Australia, is blessed with a plethora of pelagic (oceanic) seabirds. And there are ample opportunities for sea-birders, either hard-core (they’re a weird bunch!) to indulge their obsession; or itinerants and dabblers, to whet/appease their interest and, usually, add a few birds to swell their life lists. I fall essentially into the latter group, though I am a member of the Australasian Seabird Group (ASG), a member of the Southern Oceans Seabird Study Association (SOSSA), and am coming up for my tenth trip on their renowned/notorious pelagic trips out of Wollongong on the redoubtable Sandra K.

Last year, I participated in the “SOSSA pelagic” on 7 July, my first pelagic since 2002, and my first Sandra K trip with a decent (digital) camera.

My bird of the trip was without doubt the Buller’s Albatross Thalassarche bulleri, of which there were probably up to three or four following the boat at times. Not just because it was my only ‘new’ bird for the trip (number 589 on my Australian List), but simply because it is such a beautiful bird. 

Buller's Albatross is a stunning bird!

Buller’s Albatross is essentially a bird of the seas around New Zealand, though it forages into south-eastern Australian waters and there are seasonal movements by some birds across the southern Pacific to the Humboldt Current off the coasts of Chile and Peru in western South America.

The breeding grounds are located on isolated islets in several of New Zealand’s offshore island groups. These include the Snares (latitude 48.03 S) and Solander Islands (46.57 S) off South Island, the Sisters and Forty-fours of the Chatham Island group to the east of New Zealand (43.75 S), and a small number of pairs breed on a tiny islet, Rosemary Rock, in the Three Kings Islands group off the north-western tip of the North Island (34.18 S). 

The broad yellow bill stripes, top and bottom, are characteristic of the Buller's Albatross.

Birds of the southern population (from the Snares and Solander Islands) lay eggs in January with the chicks fledging in August-September. The more northerly population (Chatham and Three Kings Islands) however, starts earlier, laying in October-November with fledglings in June-July. 

Because of this, the two populations have long been considered sub-species, but recent trends mean they are sometimes considered as separate species – Buller’s Albatross in the south, and Pacific Albatross Thalassarche platei in the north.

Whatever their specific status, they are very similar morphologically and distinguishing them at sea is probably unreliable, despite the Pacific form being attributed with a larger/wider bill, a silver-grey rather than silver-white cap, and darker hood and feet. Further genetic, morphological and behavioural data may help sort things out.

The diet of Buller’s Albatross is mainly fish, cephalopods (squid etc), crustaceans and salps (weird barrel-shaped planktonic tunicates - http://en.wikipedia.org/wiki/Salp ).

There are probably somewhere in the order of 60,000 Buller’s Albatross (approximately 45% bulleri and 55% platei). Young birds may start returning to the breeding islands three years after fledging, but probably don’t start breeding until 10 to 11 years of age.

The Buller’s Albatross is sometimes called Buller’s Mollymawk, and if distinguishing between the two sub-species/species, bulleri is also known as the Southern Buller’s Albatross, while platei might be referred to as Northern Buller’s Albatross, Pacific Albatross or Pacific Mollymawk. If you were French or Spanish it would be Albatros de Buller, and Herr Schmidt would know it as the Bulleralbatros.

So Mr Buller’s name is firmly attached to this bird, it being given by Walter Rothschild* when naming the bird Diomedea bulleri in 1893 (Diomedea platei was described five years later, in 1898, by Reichenow*).

Diomedea was the original genus name for albatrosses, conferred by Linneaus in 1758, and refers to Diomedes, King of Thrace of Iliad fame, though the connection to albatrosses is a little convoluted and might possibly not have been the best choice. The genus Thalassarche was first raised by Reichenbach* in 1852, when he split the albatrosses into four genera, with Thalassarche encompassing the smaller southern albatrosses or mollymawks. Thalassarche means leader or ruler of the sea from Greek thalassa = sea, and arkhos, -archy = leader or ruler.

But getting back to bulleri, the name honours Sir Walter Lawry Buller*, a New Zealand lawyer and naturalist who dominated the field of New Zealand ornithology. Born in 1838, the son of a Wesleyan missionary, he is best known in ornithological circles for his book, A history of the birds of New Zealand, initially published in 1873, and later expanded and republished in 1888 with chromolithographic plates by J. G. Keulemans.

Missy

On a brief trip to Cairns and the Atherton Tablelands earlier this month, I held hopes of seeking out several species of bird I had not yet seen, and that had eluded me on two previous trips to the region over the past decade. These included the Southern Cassowary, Chowchilla, and White-browed Robin as good to reasonable chances; and Great-billed Heron, Pale-vented Bush-hen, and Lesser Sooty Owl as less likely targets.

Unfortunately, the weather didn't live up to expectations of beautiful one day and perfect the next, and indeed, once the rain set in at the end of our first day it didn't stop until well after we were on the plane back to an only slightly more wintery Canberra.

This meant the Chowchillas that are resident in the rainforests around the accommodation we had in Kuranda went to ground (pun intended, sadly) and were not heard at all so could not be tracked down; nor was the local Lesser Sooty Owl calling; and I wasn't prepared to subject the hire car to the dirt (mud?) roads I had in mind for searching for the White-browed Robins. 

The end result was that I ended up getting to see only one of my key target birds. But it is a magnificent bird! 

So because there aren't many photos to show for my efforts, I've resorted, rather pathetically, to showing several bits of photos in a kind of jigsaw puzzle build-up to the finale. And even that is still only part of the bird - the conditions were so dark and wet that only flash photography was possible and this presented its own problems.

massive feet.

Exposed and hairy...

itself carunculated in gaudy orange, crimson and cobalt.

This is Missy, the people-habituated female cassowary that visits Cassowary House just outside of Kuranda in Far North Queensland.

Although well accustomed to people, and expectant of daily handouts of fruit, Missy is a wild bird who comes and goes as she pleases. She approached me to within about 1 metre on occasion, a slightly daunting prospect given their reputed aggressive nature and ability to disembowel with a single rake of their massive claws. 

But she was ever the 'lady' and it was a privilege to see such an amazing and endangered bird up so close and personal. And my apologies for calling her 'Mama Cass' until I discovered the name Missy had nomenclatural precedence. 

Magnificent Mushroom

Way, way back in 1976, in my A-Level biology class at school in Singapore, I first heard of a peculiar type of fungus, the name of which, Phallus impudicus, says it all (Phallus, well…; and impudicus meaning shameless or immodest). Its common name is somewhat less explicit but just as appropriate - the Common Stinkhorn.

A few years later, while an undergrad at university in Canberra, I bought a book titled The Sex Life of Plants, by Alec Bristow (Cassell Australia, 1978) for which the frontispiece (if not the dust-jacket!) is a very suggestive drawing of Phallus impudicus below the flower of a species from the pea family called Clitoria ternatea.

Ever since, I have wanted to see in the wild any of the Phallus species. Not purely for any puerile titillative reasons you understand, but because of their remarkable structure, and because I have a general interest in fungi along with so many other things in nature.

Well, it has finally happened! While in Cairns last weekend, I saw two specimens of a related species, Phallus indusiatus, which if anything is more incredible in structure than P. impudicus. [indusiatus is from the Latin meaning 'wearing an undergarment'.] They were thrusting from the mulch around the bushes in the immaculately manicured gardens of the motel/resort we were staying at, just metres from the door of our unit.

Phallus indusiatus, the Bridal Veil Mushroom, is also known variously as the Veiled Lady, Long Net Stinkhorn, Crinoline Stinkhorn, Basket Stinkhorn, and Bamboo Mushroom.

P. indusiatus is one of around 30 species in the genus Phallus, the stinkhorns, in the family Phallaceae. They are generally of tropical distribution, with several species occurring in Australia. P. indusiatus is widely distributed and has been found in Africa (Zaire, Congo, Nigeria and Uganda), South and Central America (Brazil, Guyana, Venezuela, Tobago, Costa Rica), Mexico, Asia (Japan, southern China, Taiwan, India, Malaysia and Indonesia), and in Australia. Most species, however, are more restricted in range than this. http://en.wikipedia.org/wiki/Phallus_(fungus)

They are called stinkhorns because, unlike most mushrooms that shed spores into the air for dispersal, these produce a sticky spore mass on their conical tip which produces a strong carrion-like odor. This attracts insects, particularly flies, which then help disperse the mushroom’s spores.

 

Flies, in this case a sarcophagid fly, are attracted by the putrescent odor produced by the slimy spore mass of Phallus indusiatus.

And for anyone wondering – yes they are edible! And no, I didn’t try it. They are apparently rich in protein, carbohydrates and dietary fibre, and are used in Chinese cuisine, particularly stir-fries and chicken soup. They are now grown commercially and are also used in Chinese medicine, containing various bioactive compounds as well as having antioxidant and antimicrobial properties.

Wikipedia has lots of interesting information, including on culinary aspects, folklore, chemistry and so on, and is well worth a  read: http://en.wikipedia.org/wiki/Phallus_indusiatus

Capricornia's Terns

During my trip to the Capricornia cays of the Great Barrier Reef earlier this year, one group of birds in particular stood out for me – the terns.

Perhaps this is partly because the only new bird I got for the entire trip was a Roseate Tern, but also because they were prominent both in numbers and species. And they’re beautiful! In all, I saw eight different species of tern. 

The gulls and noddies are closely related to the terns, and though the details of their relationships are still being disputed and resolved, they are currently all included under a single family, the Laridae. It seems the noddies represent the oldest lineage of the group, followed by the gulls, and the terns are the most recently evolved, but even so, we are talking about 40-50 million years ago.

So I'll start with the noddies. The Black Noddy Anous minutus is one of the key species we were surveying on the trip, and we counted many thousands of them (see previous posts). They are beautiful birds, but very noisy at their breeding colonies and one could be forgiven for thinking they lived up to their name - anous means having no nous, i.e. "stupid bird". I also saw a single Brown Noddy Anous stolidus - which essentially means "stupid stupid bird" - but didn't manage a photo. It was too smart and flew away!

Black Noddies are very vocal, making a range of clicks, churrs, and rattles day and night.

Black Noddies build a nest of pisonia leaves glued together with faeces.

During the day, Black Noddies will sunbathe, often in sociable groups.

This pair of Black Noddies is in pair-bonding flight: rapid synchronised flying with clicking contact calls.

Silver Gulls Chroicocephalus novaehollandiae are Australia's most common and familiar gull, and are often taken for granted. But they are exquisitely beautiful birds. They generally breed in less accessible locations, often on offshore islands, so it was wonderful to be able to see the various stages of breeding on Heron Island, from eggs through to adolescents, all together.

Of the terns, I saw a Caspian Tern Hydroprogne caspia first (in Gladstone), Crested Terns Thalasseus bergii were around but less common on the islands than they often are in coastal towns and harbours, and it was good to see a group of eight Lesser Crested Terns Thalasseus bengalensis which I don't see in my more usual southern haunts. And a flock of 20 Little Terns Sternula albifrons, together with the lesser cresteds, were part of an amazing mixed species high tide roost on Northwest Island.

Scattered amongst the other birds of the high tide roost were 20 Little Terns - they're the grey and white birds with the black bills and caps, and are much smaller than the Lesser Crested Terns.

A Common Tern Sterna hirundo, which aren't really all that common in Australia, had commandeered a buoy just off from the jetty on Heron Island, and another was seen briefly on Lady Musgrave Island.

As I mentioned, the Roseate Tern Sterna dougallii was the only new bird I came across on the trip - my 590th bird for Australia. 

A small group of Roseate Terns at Heron Island, though I saw my first a few days earlier on Northwest Island. Three of these are in breeding plumage - red bills and legs, full dark caps; but one looks like a young bird with dark bill, patchy forehead, and black legs.

But perhaps my favourites were the Black-naped Terns Sterna sumatrana and Bridled Terns Onychoprion anaethetus.  I had previously only seen these species in small numbers and usually from quite a distance, so to see so many so close was very special.
