Newsletter – 5/14/12

Three weeks ago we had the Cape Petrel. Here is the Black-winged Petrel, another species, like the White Tern and Grey Ternlet, that I had seen twenty years ago on Lord Howe Island and was keen to photograph on Norfolk Island. With a length of 28-30cm/11-12in and a wingspan of 67cm/26in, this is quite a small species with elegant black, grey and white markings and a stubby, hooked bill, visible in the first photo.

It nests on both the main island and Phillip Island – where it was quite abundant – and was easy to find as, unlike most petrels and shearwaters, it is active around the breeding colonies in daylight. Most petrels and shearwaters come ashore under cover of darkness to reduce the risk of avian predators such as raptors and gulls, but the Black-winged has historically nested on predator-free islands. ‘Historically’ here means before human settlers introduced predators such as feral cats.

Black-winged Petrels are accomplished fliers and spent much time in aerial acrobatics around and over cliffs. The generic name Pterodroma means ‘winged runner’ and refers to their aerial agility. The one in the second photo is coming in to land near its nesting burrow and passing some Norfolk Island Pines. All petrels and shearwater, except the Giant Petrels, have very weak legs and once on the ground are barely mobile using their wings to drag themselves along on their bellies.

Like many island birds, they seemed unafraid and didn’t appear agitated when approached closely to have their photos taken. The fourth photo shows the tubular nostrils characteristic of this family of birds and their close relatives the albatrosses and storm-petrels. All these ‘tube-nosed’ birds are thought to have a strong sense of smell – very unusual for birds – that helps them find both marine prey and their nesting burrows on dark nights, and the birds themselves apparently have a strong musty odour during the breeding season.

Black-winged Petrel (Pterodroma nigripennis) by Ian Montgomery 4

The hooked bill helps the birds grasp slippery prey – mainly squid and small fish – and the bills have sharp cutting edges. The Black-winged is one of about 36 global species of Pterodroma petrels collectively and, I think unfairly, called Gadfly Petrels, in reference to their erratic flight. As I’m sure you know, Gadflies are nasty blood-sucking insects such as Horse and March Flies, and there must be other more congenial erratic fliers after which they could been named. Anyway, Gadfly Petrels feed on the wing by snatching prey from the surface of the water and rarely alight on the water or dive.

The Black-winged Petrel breeds on islands in the south Pacific including Lord Howe, Norfolk, various islands around New Zealand and on several in French Polynesia. Helped by protection and the removal of predators such as feral cats, its population is increasing and it has bred on Lord Howe only since the 1960s. There are unproven recent reports of it breeding on some islands on the east coast of Australia, where it is generally rare. Outside the breeding season, it is highly pelagic and ranges widely over the Pacific as far as southern Japan and Mexico.

Best wishes

Ian’s Bird of the Week – (Norfolk Island) Golden Whistler

Ian’s Bird of the Week – (Norfolk Island) Golden Whistler ~ by Ian Montgomery

Newsletter: 5-4-12

My apologies for a belated bird of the week. When I was in Eungella recently chasing the so-named Honeyeater, I encountered a very obliging male Golden Whistler, below, so I’ve chosen it to introduce this week’s subject.

Australian Golden Whistler (Pachycephala pectoralis) by Ian

It’s one of the most gorgeous of the woodland birds of eastern and southern Australia and one of those unusual birds that, unlike Rainbow Lorikeets for example, both look and sound strikingly beautiful. It featured as bird of the week in January 2005, but I don’t suppose you’ll mind me repeating it and I want to share with you the interestingly different Norfolk Island equivalent.

Australian Golden Whistler (Norfolk Island) (Pachycephala pectoralis xanthoprocta) by Ian

The bird in the second photo, one of a pair we encountered, is, or could be, an adult male Norfolk Island Golden Whistler. I say ‘could be’ because there, the adult males do not develop the striking yellow and black plumage of the mainland races and remain ‘hen-plumaged’, to quote Schodde and Mason. This was recognised early on in the settlement of the island and it was original described as a separate species, the Norfolk Island Thickhead (Pachycephala means ‘thick-head’) P. xanthoprocta, where xanthoprocta refers to the yellow vent. Here is a painting of a pair by John Gould.

Australian Golden Whistler (Norfolk Island) (Pachycephala pectoralis xanthoprocta) by Ian Drawing

He has labelled the bird in the foreground as a male, and the one in the background as a female. There are subtle differences in plumage, with the female being more lemon-yellow underneath and the male being more buffish yellow and. having darker dark lores. I haven’t been able to find whether these differences are consistent, but it seemed to me that the bird in photo above (141464) looks more like the Gouldian male than its partner below (141440).

Mainland juvenile Golden Whistlers have rusty margins on the wing feathers and this is the case with the Norfolk Island birds, as shown in the next photo taken on a different occasion when we were hanging around waiting for the Norfolk Island Parakeets to show up.

To this day, the taxonomic status of the Golden Whistler ‘complex’ remains unresolved. There are different races on the mainland and in neighbouring locations such as New Guinea, New Britain and Fiji. The mangrove-inhabiting Golden Whistler of northern and western Australia has been elevated to specific status but the others have remained in the too-hard basket and are still lumped together as a single species. It seems to me unusual for avian taxonomists to be stumped by a problem like this, but maybe they’ve met their match.

Best wishes

Ian

Very interesting and a beautiful bird. I couldn’t resist finding out what this “whistler” sounds like. It is very pretty sounding. Take a listen.

Sound of Golden Whistler

In that day the LORD will whistle for the fly that is at the end of the streams of Egypt, and for the bee that is in the land of Assyria. (Isaiah 7:18 ESV)

The Whistlers are found in the Pachycephalidae – Whistlers and Allies. There are 58 members of the family. This Australian Golden Whistler (Pachycephala pectoralis xanthoprocta) is one of those subspecies; there are at least 7 subspecies. The “Norfolks” are found on the Norfolk Island, as Ian mentioned.

The Norfolk Golden Whistler (P. p. xanthoprocta) declined for many years due to habitat loss and fragmentation and possible due to introduced predators such as the Black Rat. Most of the population is now restricted to the Norfolk Island National Park. This has resulted in it being listed as vulnerable by the Australian Government.

Ian’s Bird of the Week – Common White Tern

April 2, 2012 by Ian

Ian’s Bird of the Week – Common White Tern ~ by Ian Montgomery

Newsletter – 4/2/12

Another species on my photo list on Norfolk Island was the (Common) White Tern. I’d admired on Lord Howe Island more than twenty years ago, before I got seriously into bird photography. They’re only Common if you’re on a remote coral or rocky island in the Pacific, Indian and Atlantic Oceans, but the label really means ‘standard’ and reflects a split of the species, not universally recognised, into ‘Standard’ and Little White Tern. It used to have the attractive name ‘White Noddy’, until some prosaic purist decided that only terns belong the genus Anous were real Noddies.

They are unusually looking terns, with a pointy, slightly upturned bill and very white, actually translucent, feathers, usually described as ‘ethereal’. Seen against the sunlight, the effect is something like looking at an X-ray as in the second photo. In this one, you can see the bill is very thin laterally so it is shaped more like a pair of scissors.

White Terns are numerous on Norfolk Island and as they nest on the branches of Norfolk Island Pines, you see them all over the island. If you’re used to seeing terns near water, it’s initially slightly disconcerting to see them flying around in forest. Many of these are parents feeding young, but do also see pairs or small groups of birds, as in the third photo, and very pretty they are too.

In March, the breeding season is nearly over, but there are still some hungry and very bored looking chicks in the pines waiting for a feed. The single egg is laid precariously in a concavity on a branch or palm frond. Norfolk Island pines, with their horizontal limbs, are ideal for this and the recent establishment of breeding White Terns on Lord Howe Island can probably be attributed to the introduction of Norfolk Island Pines.

The fourth photo shows a nearly fledged juvenile. At this age they look like furry toys, but the slightly younger ones, that were just losing the last traces of their down, often looked quite comical. The bird in the fifth photo shows one that looks for all the world like an aged goddess of the silver screen who doesn’t believe in growing old gracefully, with faux eye-lashes, smudged mascara, thinning hair, an ancient fur coat and a grumpy expression.

Hopefully, though, it has a bright future ahead.

Best wishes

What a description of the that last photos. Puts a chuckle in you. What is so amazing is that it fits.

Anyway, Terns are in the Laridae – Gulls, Terns and Skimmers Family and see Ian’s Laridae Family of photos at his Birdway site. More of his photos of the Common White Tern can be Here.

“The White Tern (Gygis alba) is a small seabird found across the tropical oceans of the world. It is sometimes known as the Fairy Tern although this name is potentially confusing as it is the common name of the Fairy Tern Sternula nereis. Other names for the species include Angel Tern and White Noddy.

Wow! Look at this from ARKive:

http://www.arkive.org/common-white-tern/gygis-alba/image-G88261.html

The White Tern is a small, all white tern with a long black bill, related to the noddies. It ranges widely across the Pacific and Indian Oceans, and also nests in some Atlantic islands. It nests on coral islands, usually on trees with thin branches but also on rocky ledges and on man-made structures. The White Tern feeds on small fish which it catches by plunge diving.

…there are costs associated with tree nesting, as the eggs and chicks are vulnerable to becoming dislodged by heavy winds. For this reason the White Tern is also quick to relay should it lose the egg. The newly hatched chicks have well developed feet with which to hang on to their precarious nesting site. It is a long-lived bird, having been recorded living for 17 years.” (Wikipedia)

Looks like the Lord, in his creation of these chicks, provided feet that can help them hold on.

All the birds of the heavens made their nests in its boughs; under its branches all the beasts of the field gave birth to their young, and under its shadow lived all great nations. (Ezekiel 31:6 ESV)

Ian’s Bird of the Week – Pacific Robin

March 26, 2012 by Ian

Pacific Robin (Petroica multicolor) by Ian 1

Ian’s Bird of the Week – Pacific Robin ~ by Ian Montgomery

Newsletter – 3/25/12

The Pacific Robin was another bird that I was keen to photograph on Norfolk Island. It has only recently been split from the mainland Scarlet Robin and, until that happened, it attracted little attention. As a consequence, I had trouble sourcing photos, particularly of adult males, and getting reliable material for the description of the species for the digital version of the Australian field guide by Pizzey and Knight.

It’s not common on Norfolk Island with an estimated population of 400-500 species and its distribution is restricted to areas of native forest. Happily, there was a resident family at the place, Palm Glen, where we did regular evening vigils for the Norfolk Island Parakeet and, being more confiding than Scarlet Robins, the members of the family proved to be good subjects for photography. The first photo shows the adult male. At first glance, it looks like a small Scarlet Robin, but closer examination reveals the diagnostic lack of white on the flight feathers of the wing and the outer tail feathers: the only white on the wing is the secondary wing coverts. Another supposed difference is a smaller area of white on the forehead, but this bird at least seemed to me to show much more white, extending back to a point above the rear of the eyes. If you’re interested, compare with http://www.birdway.com.au/petroicidae/scarlet_robin/index.htm .

The second photo shows the adult female, left, and the juvenile, right, posing obligingly for comparison. Both lack the obvious white forehead spot characteristic of, in fact diagnostic of, their Scarlet Robin counterparts and also lack white in the outer tail feathers. The colours are also richer and the wing stripes are a deeper buff, almost blending with the buffish-brown of the rest of the wings and back. The third photos shows the same female face-on, and the lack of the white spot is more obvious: there is only slight white scalloping.

The fourth photo is another shot of the same juvenile, showing the lack of white on the outer tail feathers.

Pacific Robin (Petroica multicolor) by Ian 4 Juv

Having noticed the large amount of white on the forehead of the male, I kept an eye out for another individual and eventually photographed this one, fifth photo, on nearby Mount Pitt. This too had a large white spot.

Pacific Robin (Petroica multicolor) by Ian 5

The Pacific Robin, as now described, is quite widely distributed on islands in the South Pacific from the Solomons in the north via Vanuata and Fiji to Norfolk Island in the south. It is quite variable in plumage and 14 races have been described. It is closely related to the Tomtit of New Zealand, the males of which vary in colour from the white-breasted (North Island), through yellow-breasted (South Island) to the complete black race on the Snares: http://www.birdway.com.au/petroicidae/tomtit/index.htm. There is clearly enough material here to keep a South-sea-island-loving taxonomist busy for at least a lifetime and I won’t say anything further except to note an interesting historical twist in the story of the splitting of the Pacific and Scarlet Robins.

Norfolk Island was settled in the same year as Sydney, 1788, and one result of that was that the Scarlet Robin was described using a Norfolk Island specimen (the type specimen) by German Naturalist Johann Gmelin in 1789 and given the specific name multicolor. When the species was split 210 years later, the rules governing taxonomy insist that this name remains with the Norfolk Island bird, so the mainland species becomes the new one and was named boodang after the SE Australian race (up till thenPetroica multicolour boodang). To avoid confusion in Australia (at the risk maybe of increasing it in the Pacific Islands) the common name Scarlet was transferred to the new species and the new name Pacific was given to the old species.

I’m sure this family of birds at Palm Glen would be astounded to learn that their kind is the subject of such intense scrutiny!

Best wishes
Ian

He answered and said to them, “When it is evening you say, ‘It will be fair weather, for the sky is red’; (Matthew 16:2 NKJV)

Those changes aught to keep the Bird Guide writers busy keeping up with the divisions and name changing. What a gorgeous bird and fantastic photography. Thanks again, Ian, for sharing all these great birds.

It seems small in the photos, so I checked to see its size. “The Pacific Robin is a small passerine, 4.5-5.3 in (11.5–13.5 cm) long and weighing .31-.38 oz (9–11 g.) Over much of its range it is the smallest species of bird. Pretty small.

The Pacific Robin is in the Petroicidae – Australasian Robins Family. Also see Ian’s Petroicidae Family.

“The Pacific Robin is a seasonal breeder, although the timing of the breeding season varies across its range. Information on the timing of the season is patchy or absent in many islands. On Norfolk Island the breeding season is from September to December, and in Vanuatu the season is from October to January. Parents with young have been seen in mid August in the Solomon Islands and in June through to September in Samoa. The species builds a compact nest which is a cup of plant fibres and spider webs. The outside of the nest is decorated with moss and lichen, and is therefore easily overlooked. The nest is usually set into a fork or stump on a tree branch, or on a horizontal branch.

Around two to four eggs are laid in each clutch, with two being the typical clutch size in Norfolk Island, and two to three being typical in Fiji. The eggs are dull grey or greenish, and are incubated by the female. The nests of Pacific Robins are parastised by Fan-tailed Cuckoos where the two species co-occur.” (Wikipedia)

Ian’s Bird of the Week – Norfolk Island Parakeet

Norfolk Parakeet (Cyanoramphus cookii) by Ian 1

Ian’s Bird of the Week – Norfolk Island Parakeet ~ by Ian Montgomery

Newsletter ~ 3/15/12

Well, your unwavering moral and spiritual support has done it again: here is the Tasman or Norfolk Island Parakeet (better known here as the Green Parrot to distinguishing it from the introduced Red Parrot – the Crimson Rosella). Thank you very much!

We were met at the airport by Albury-Wodonga birder Dougald Frederick, excitedly carrying the news that there was a vagrant Ringed Plover at Slaughter Bay. So we picked up the hire cars, checked into our accommodation and went down to the Bay, whose name is a corruption of Slackwater Bay, rather than the site of a messy event in the generally nasty penal history of the island. Ringed Plovers are indeed rare in Australia, but I was brought up with them in Ireland and couldn’t conceal my impatience to get to Palm Glen near Mount Pitt, where Dougald had been regularly seeing the Parakeets in the evening.

Eventually we went there and eventually, just before sunset and after my travelling companions had left to buy food for breakfast, the Parakeet in the first photo arrived and starting feeding on the feral guavas, fruiting prolifically around the picnic area. The guavas have dense foliage and the red fruit made the feeding Parakeets very hard to see. They were easier to see, but harder to photograph, when they used the top of the numerous tall Norfolk Island pines as vantage points, second photo. This less brightly coloured bird is a female or juvenile; the ones in the first and third photos are males.

Norfolk Parakeet (Cyanoramphus cookii) (fem or juv) by Ian 2

After that, we visited Palm Glen regularly in the evenings and always saw at least one, distant Parakeet, with a flock of 6 on the second day when I took the third photo, the last occasion on which the birds were close enough to photograph. As well as being a pleasant spot to watch the sunset, it was also a good site for the other two remaining endemic species, the Norfolk Island Gerygone and the Slender- or Long-billed White-eye, and for the endemic races of the Golden Whistler and Grey Fantail.

Norfolk Parakeet (Cyanoramphus cookii) by Ian 3

The Norfolk Island Parakeet was originally regarded as a race of the Red-crowned Parakeet of New Zealand until genetic studies showed that it was sufficiently distinct to warrant the status of a full species. It came close to extinction in the 1980s when the population declined to an estimated 32 individuals with 4 breeding pairs (the sex ratio was heavily biased towards males). Since then, it has been the subject of an intense recovery program to control introduced predators and competitors, and the population is now estimated at perhaps 200 individuals, though our birding guide on Monday, Margaret Christian reckons that that is optimistic, given the frequency of sightings.

It’s a lovely island, friendly and historically interesting, so we have had an enjoyable week. If you intend to visit, we can highly recommend our accommodation, Poinciana Cottages – we all agreed that we could quite happily live in them permanently, and they gave me a free upgrade from an extra bed in one of our two cottages to solo occupancy of a third cottage. If you’re birding, then a morning spent with Margaret Christian is essential and she bakes delicious cake for morning tea. We also did a trip to Phillip Island for the seabirds. That too is highly recommended if the weather is suitable and David Bigg is the person to see about that.

Best wishes and much gratitude,

Ian

Glad we could assist with our prayers. What another neat creation to observe. I love the way they were designed to blend right in with the plants they like to eat. It protects them, but it does make for the challenge of birdwatching photographers and watchers. Thanks for your persistence, Ian.

Look at the birds of the air, for they neither sow nor reap nor gather into barns; yet your heavenly Father feeds them. Are you not of more value than they? (Matthew 6:26 NKJV)

The Norfolk Parakeet (Cyanoramphus cookii), also called Tasman Parakeet,[1] Norfolk Island Green Parrot or Norfolk Island Red-crowned Parakeet, is a species of parrot in the Psittacidae family. It is endemic to Norfolk Island (located between Australia, New Zealand and New Caledonia in the Tasman Sea).

Its natural habitats are subtropical or tropical moist lowland forests and plantations. It is threatened by habitat loss.
