West Pacific Odyssey part 5: Solomon Islands to Chuuk, Micronesia and beyond: 30th March – 8th April 2019.   Leave a comment

This post continues the story of the West Pacific Odyssey, the month-long epic journey on board the Professor Khromov from New Zealand to Japan.

We made a single landfall during this time at Chuuk (formerly spelled Truk) in the Federated States of Micronesia (Caroline Islands). I have visited Chuuk previously in 2010 as part of a wider tour of Micronesia. As I didn’t get to see much of the island group on this tour I’ve added a number of photos taken then.

 

Leaving Kolombangara in the Solomon Islands behind we sailed along the western side of Bouganville and close to the southernmost tip of New Ireland. The following day we crossed the Equator and we spent the following day at sea as well. On 3rd April we arrived at Chuuk in the Caroline Islands and spent the latter part of the day and the following morning on the island. The next three days were spent at sea. We arrived in Japanese waters on the 9th.

 

As we left the Solomon Islands we had great views of the volcanic summit of Kolombangara (see post four on the WPO for more).

 

The following morning we passed to the west of the island of Bougainville. Although geographically part of the Solomons, administratively it belongs to Papua New Guinea although it has been lobbying for independence for a long time. Many of the tribes in the highlands jealously guard their territory and are suspicious or even show violence to outsiders. Recently the security situation has eased and a bird tour to this little known island with its myriad of endemics was advertised for 2020. I’d absolutely love to go but a) is it really safe? b) am I fit enough to hike up the top of that mountain? and c) could I afford it? its incredibly expensive. I think this is as near as I’ll ever get to Bougainville.

 

On route we found a few Little Terns roosting on floating coconuts …

 

… but the birding highlight was this Beck’s Petrel, a small version of Tahiti Petrel which is mainly seen around Bougainville and New Ireland.

 

Beck’s Petrel. These images are shown at a smaller size as the bird was so distant.

 

Also in the area were some more Heinroth’s Shearwaters …

 

… and the next day, close to the PNG island of New Ireland we saw these Pygmy Sperm Whales.

 

They are very hard to separate from Dwarf Sperm Whale but as Pygmy Sperm Whale has more of a falcated dorsal fin.

 

As we approached New Ireland the sea state got calmer and calmer …

 

… and just as happened when we approached the Equator on the Atlantic Odyssey three years earlier, the sea took on an oily appearance. We were entering the doldrums.

 

However that wasn’t to last long, with New Ireland disappearing away in the distance we saw a waterspout, that is a tornado at sea.

 

As the day drew on the clouds got darker and darker …

 

… and there was a dramatic sunset.

 

It was really rough in the night, not what we expected as we neared the Equator, with a big, slow swell that moved everything around in your cabin. OK I’ve been through much worse on the way down to Antarctica but this is supposed to be the doldrums. The outer bulkheads were closed and we were banned from going on deck. There had been plans to stop the ship and going for a swim at 0 degrees (latitude that is not temperature) but of course that was cancelled, as was all the usual tomfoolery that usually accompanies ‘crossing the line’.

 

All we could do was gather on the bridge and watch the GPS as we moved from the southern to the northern hemisphere. It was the 1st April, if there were any ‘April fools’ it was us.

 

Taken within four metres of ‘crossing the line’.

 

Around the Equator and during the bad weather we saw hardly any birds at all, but between the Solomons and New Ireland and to the south and north of Chuuk we had good numbers of the common tropical seabirds including Sooty Tern …

 

… Red-tailed Tropicbird …

 

… this Red-tailed Tropicbird has a all white tail (just to confuse things).

 

Also seen were frigatebirds, this is an adult female Lesser Frigatebird.

 

Three species of booby were commonly seen around the ship, chasing flying fish or roosting on the superstructure. This an adult Brown Booby.

 

This Brown Booby can be sexed as a female on account of the greenish facial skin. A recent publication ‘Oceanic Birds’ by Howell and Zufelt, which wasn’t available when I did this trip, proposes that there are three species of Brown Booby, this is the Indo-Pacific form.

 

This is a adult Masked Booby …

 

… you can just see it’s pale eyes in the photo. The dark eyed race tasmani which occurs to off Australia has been illustrated earlier in my WPO account.

 

Red-footed Boobies come in several morphs. This is a typical brown morph here seen chasing flying fish.

 

This is the light morph. Red-footed Booby is the smallest of all the six species of booby.

 

Identification is complicated by these partially brown dark-tailed immatures.

 

Boobies would often perch on the superstructure as they scanned the ocean for flying fish and would sometimes roost there.

 

We arrived at Moen on the main island of Weno in Chuuk, one of the four states of the Federated States of Micronesia, in the afternoon but it took ages to get customs and immigration clearance.

 

… but as soon as we could we went for a walk …

 

Norfolk Island and New Caledonia were fully westernised developed islands, whilst the remoter villages in the Solomons were basic but rustic and attractive. Chuuk on the other hand just seemed tatty with derelict buildings and poorly repaired roads.

 

This derelict ship photographed over a line of washing between two tumbledown shacks sums up the air of neglect.

 

The people were welcoming enough though (see also the cheerful chappie in the photo two above)

 

In 2010 I did a comprehensive tour of Micronesia visiting some of the Mariana Islands, and Palau plus Chuuk, Yap and Pohnpei in the Federated States of Micronesia (Caroline Islands). As I didn’t take many good photos of Chuuk on this visit I’ve included some taken in 2010 to give a better idea of the scenery and wildlife of this island group. In 2010 we were staying in a hotel outside the town and so had to drive through it every time we wanted to visit anywhere. They were having big problems with the high tides flooding the streets. I don’t know if they have fixed it now or whether it was neap tides during our visit in 2019. This photo was taken in 2010.

 

In 2019 we birded an area of woodland around the ‘Japanese gun’ however you had to pay to see the gun itself and time was pressing. In 2010 we did visit the gun and accessed it via a tunnel through the hillside. Photo taken in 2010.

 

During WWII the Micronesian Islands were of great strategic importance, especially Chuuk due to the huge size of the lagoon and were occupied by the Japanese. This large gun was installed to defend the island of Weno from attack. Photo taken in 2010.

 

 

From Wikipedia:

Chuuk Lagoon, previously Truk Atoll, is an atoll in the central Pacific. About 1,800 kilometres (1,100 miles) north-east of New Guinea, it is located mid-ocean at 7 degrees North latitude and is part of Chuuk State within the Federated States of Micronesia. A protective reef, 225 kilometres  around, encloses a natural harbour 79 by 50 kilometres, with an area of 2,130 sq km. It has a land area of 93.07 square kilometres (35.93 square miles), with a population of 36,158 people and a maximal height of 443 m. Weno city on Moen Island functions as the atoll’s capital and also as the state capital and is the largest city in the FSM with its 13,700 people.


“Truck atoll” was the Empire of Japan’s main naval base in the South Pacific theatre during World War II. It was the site of a major U.S. attack during Operation Hailstone in February 1944, and Operation Inmate, a small assault conducted by British and Canadian forces during June, 1945. 

 

The gun was situated here to guard the approaches to Moen. However now the platform allows good views of the birds in the marsh below. Photo taken in 2010.

 

We saw a number of endemic or near endemic species in the area including this Purple-capped Fruit Dove. Photo by from weedmandan

 

… and the endemic and elusive Caroline Ground Dove. Photo by from weedmandan

 

Another Caroline Island endemic seen was the Oceanic Flycatcher Photo from weedmandan

 

As it was April the Pacific Golden Plovers were now in breeding plumage and about ready to head for the Siberian Arctic. I was given this photo and the ones of the Teardrop White-eye and Chuuk Monarch by another participant. Unfortunately I didn’t note their name. If you are reading this please let me know and I’ll credit you accordingly.

 

In 2010 we travelled to the island of Tol South in the south-west of the lagoon. There were two species, Teardrop White-eye and Chuuk Monarch that couldn’t be seen elsewhere. Also we saw Micronesian Pigeon which we also saw later in the trip. The climb was really tough and in parts much steeper than shown here. It was a real case of scrambling up on your knees. On the WPO a half-day trip to Tol South was offered but I declined. Those that did it managed to see the white-eye and the monarch ….

 

… indeed they saw something I didn’t see in 2010, the gorgeous white male monarch. As it was now the breeding season they might have been more conspicuous. Our late autumn visit in 2010 meant that the only ones I saw were drab juveniles.

 

When I went nine years earlier we had some local guides, indeed the entire village tried to be our local guide – which wasn’t very helpful.

 

The view from half-way up across the lagoon was stunning. Some of climbed much higher up Mount Winipot to see the pigeon, it was a really tough slog. Photo taken in 2010.

 

Here is the Teardrop White-eye also known as Grand Chuuk White-eye, a species found only on this island.

 

Our tour in 2010 was much more relaxed. Infrequent flights between the islands meant that we often had time on our hands, not something that you see very often on a bird tour. So we took the opportunity to go snorkelling. I’m not a great swimmer and I found it a bit tricky but I thoughtfully enjoyed it. Participant Richard Clifford was a keen snorkeler and brought an underwater camera. Photo by Richard Clifford in 2010.

 

The coral reefs were beautiful and full of lovely fish, this one is a Redfin Butterflyfish. Photo by Richard Clifford in 2010

 

But Chuuk Lagoon has the reputation of being the best wreck diving in the world. The lagoon was the base of operations for the Japanese Navy, an attack ‘Operation Hailstone’ in 1944 caught the Japanese unaware and the Americans were able to inflict major damage see Wikipedia – here   The lagoon is littered with wrecked supply ship and some military craft. Photo by Richard Clifford in 2010

 

I had been interested in military aircraft as a child, so seeing the remains of a Mitsubishi Zero on the bottom of the lagoon was pretty exciting. Photo by Clubmarine

 

As we left the Chuuk Lagoon and entered the open ocean we encountered a number of ‘Tropical Shearwaters’.  The thinking is that these species are essentially non-migratory and so each breeding population has evolved into its own species with distinct vocalisations and plumage. However they are certainly difficult to tell apart. Some like Bannerman’s Shearwaters and Byran’s Shearwater have already been given specific status. This form Puffinus bailloni dichrous is colloquially known as ‘Atol’ Shearwater. Photo taken by Mike Danzenbaker in the Caroline Islands. see here

 

We slowly made our way north, first through Micronesian waters then through the waters of the Mariana Islands, crossing the Mariana Trench which at nearly 11,000 metres is the deepest point in the ocean.

 

Of course we saw many of the birds I have illustrated earlier but we also started to see a number of shearwaters and storm-petrels, evidence that we were heading out of the tropics but I’ll save most of those photos for the final post. We also saw a number of cetaceans including this close Omura’s Whale. This was a species I hadn’t heard of before, although it was formerly called the ‘small-form’ Bryde’s Whale. It was only described as a full species in 2003 which is later than the publication date of the cetacean guide that I use. It’s range is tropical west Pacific from Sumatra/Java east to New Ireland and north to Japan. It reaches a maximum length of 12m so would just fit in our garden.

 

We also saw four (but only caught two in this shot) of the rare Blainville’s Beaked Whale.

 

Not too far north of Chuuk we found our first Matsudeira’s Storm-petrel. We were getting into the realm of the Japanese seabird specialities. More of that in next and final post about the West Pacific Odyssey.

 

But I’ll conclude with this photo of an exhaling Omura’s Whale seen over the Mariana Trench.

Central Peru part 7: the pelagic – 26th November 2016.   2 comments

This is the final post about the Central Peru tour I did in November 2016 and deals with the pelagic boat trip on the final day.

 

 

 

central-peru-map

Over the last 17 days we had followed this route clockwise from Lima. Now we were back at the capital for a final day of birding – not onshore but at sea on a pelagic trip 35 nautical miles (65 km) offshore.

 

img_8577-the-port

So early on the final day it was down to the docks ….

 

img_5284-peruvian-sub

…. to set off on our little open boat past the Peruvian Navy’s submarine ….

 

img_8575-from-the-boat

and head out to sea ….

 

img_8353-hudsonian-whimbrel

As we passed the breakwater we saw a Hudsonian Whimbrel ….

 

surfbird-california-marlin-harms

…. as well as several Surfbirds, a bird with one of the strangest non-breeding distributions on the planet, after leaving their Alaska/Yukon breeding grounds the entire population occupies a narrow intertidal band a few metres wide and 17,500 km long from Alaska to the Straits of Magellan. I wasn’t quick enough to get a photo as the boat sped by so I used this shot by Marlin Harms from Wikipedia.

 

img_8574-the-coast-from-the-boat

Leaving the coast behind we headed towards the Islas Palominas ….

 

img_8542-inca-tern-flock

…. passing sizeable flocks of Inca terns …

 

img_8546-terns-and-boobies

…. and rocks covered with Peruvian Boobies.

 

img_8496-crack-in-rock

We spent some time at the Islas Palominas ….

 

img_8498-sealions

…. that held truly impressive numbers of South American Sea Lions.

 

img_8491-sealions

Many were hauled out on the rocks. The darker ones are still wet from their last swim.

 

img_8469-sealion-male

A small number of impressive bull sea lions were present.

 

img_8495-swimming-with-sealions

A boat load of people were in the water …

 

img_8479-sealion-at-sea

…. swimming with the sea lions ….

 

img_8497-swimming-with-sealions

…. whilst undoubtedly a great experience for the swimmers, I’m sure it disturbs the sea lions, all the individuals on shore are alert and moving up the rocks (our boat is much further away and the photo was taken with a 1000mm telephoto setting) ….

 

img_8506-offshore-island

…. in addition taking swimmers into such heavy surf close to the rocks is the height of folly (I was H&S man at work and can’t help doing ‘risk assessments’, even now).

 

img_8470-peruvian-boobies

Many other birds were seen including Peruvian Boobies, now much reduced in numbers compared to 30 years ago ….

 

img_8489-peruvian-boobies

…. although still providing a spectacle as they fly back to the rocks …

 

img_8478-peruvian-booby

Once very common the boobies, like several other birds of the Humboldt Current, have seen catastrophic declines due to over fishing and climate change have all had an impact.

 

img_8522-red-legged-cormorant

Three species of cormorant were seen, the elegant Red-legged ….

 

img_8544-neotropic-cormorant

….Neotropic, which is more usually seen on freshwater lakes and the Guanay Cormorant, which although the commonest, was never seen close enough to photograph.

 

img_8508-chilean-pelicans

Another ‘guanay’ bird is the Peruvian Pelican, a larger version of the more familiar Brown Pelican.

 

img_8560-guano-unloading-quay

For a centuries the droppings (guano) of all those cormorants and boobies was harvested for fertiliser apparently without harmful effects. However recently these ‘guanay’ birds particularly Guanay Cormorant have dropped markedly. On a similar trip in 1989 I recorded over 6000 Guanay Cormorants, this time we saw less than 1000. The major factors driving this decline seem to be the El Nino phenomena, climate change and overfishing. Here the loading platform and associated warehouses of the guano collectors can be seen.

 

img_8464-inca-tern

Other birds seen included the elegant Inca Tern ….

 

img_8531-inca-tern-flock

… often seen in large tightly knit flocks.

 

inca-terns

This lovely shot was taken by my friend and room-mate Steve Lowe.

 

img_8517-humbolt-penguins

The cold waters of the Humboldt Current which flows up from the Antarctic has allowed a separate species of penguin to evolve off the coast of central South America, named (perhaps unsurprisingly) Humboldt Penguin.

 

img_8553-blackish-oystercatcher

On the rocks were a number of Blackish Oystercatchers ….

 

img_8482-seaside-cinclodes

…. and the only passerine of the boat trip, Peruvian Seaside Cinclodes.

 

img_8509-offshore-islands

Leaving the islands we headed out to deeper waters.

 

img_8499-belchers-gull-pos

On an earlier post I described Belcher’s Gull as being ‘inappropriately’ named. A friend pointed out that it wasn’t inappropriate as the species was named after an Mr Belcher, so perhaps I should have said ‘unfortunately’ named. The original Band-tailed Gull was split into two – the Atlantic Olrog’s Gull and the Pacific Belcher’s Gull. I suppose we should be grateful the Atlantic species wasn’t named after any other bodily function!

 

img_8363-grey-gull

We only saw a pair of the delicately plumaged and ‘appropriately’ named Grey Gull.

 

img_8368-swallow-tailed-gull

Further out under the persistent grey clouds we saw our first Swallow-tailed Gulls.

 

img_8389-swallow-tailed-gull

Swallow-tailed Gull breeds only on the Galapagos Islands (a location I have never visited). There are just two species of gull breeding on the Galapagos, the other – Lava Gull is one just of two gull species worldwide that I have never seen. The unusually large eyes must mean that it is adapted to foraging at night.

 

img_8380-swallow-tailed-gull

The upper-winged pattern makes Swallow-tailed look like a large version of Sabine’s Gull (an Arctic breeding species that also winters in the Humboldt current). We also saw Sabine’s on the pelagic but due to the rocking motion of the boat the photos were too poor to use.

 

img_8411-franklins-gull

Another gull we saw was Franklin’s Gull, named after legendary Arctic explorer Sir John Franklin whose expedition to discover the North-west Passage ended in such tragedy. The species breeds in the prairies of North America and winters in the Humboldt Current.

 

img_8412-franklins-gull

The species occasionally turns up in the UK as a vagrant and I have seen it six times at home, all in Dorset or neighbouring Devon and Hampshire.

 

img_8432-chilean-skua

A migrant from the opposite direction was this Chilean Skua which breeds in the far south of South America.

 

img_8402-wc-petrel

Another migrant from the south was this White-chinned Petrel, the nearest breeding colonies are in the Falklands and South Georgia. Possibly not the best name for the species as the ‘white chin’ can be as little as a single white feather and can even be absent.

 

img_8401-storm-petrel-to-id

But one of the highlights of this pelagic was the storm-petrels. We saw no fewer than six species, four of which were life birds for me. These are Elliots (or White-vented Storm Petrels). The only known breeding grounds of this bird are the Galapagos and some islets off north Chile.

 

img_8403-white-vented storm-petrel

The diagnostic white vent and lower belly can be seen here, the pale panel in the underwing secondaries is best seen in the top photo.

 

IMG_5420 Wilson's SP

Wilson’s Storm-petrel is similar but much more widespread (the commonest seabird and possibly the commonest wild bird in the entire world, but we saw very few on this trip). It differs from Elliot’s by the lack of a white vent and a different flight action. I took this photo in the subantarctic in April 2016.

 

img_8405-storm-petrel-to-id

I’ve been unable to conclusively identify the storm-petrel in this picture. It is in moult which the Elliot’s weren’t. I suppose it is a Wilson’s but I have never seen them looking this long-winged. The other four species we saw can be easily excluded by rump colouration/shape.

 

wedge-rumped_storm_petrel-brian-gratwicke

From the small and crowded boat, and not having my DSLR with me, I found photographing fast-moving stormies to be very hard. The following three pictures (all of life birds) have been taken from external sources. Wedge-rumped Storm-petrel breeds mainly on the Galapagos but also along the coasts of Peru and Chile. Photo (taken from Wikipedia) by Brian Gratwicke

 

markhams_storm-petrel-cock-reijnders

Another life bird was Markham’s Storm-petrel, a large and dark stormie. Until recently its breeding grounds were unknown but colonies (underground burrows) have been found several Km inland in the Atacama Desert of Peru and Chile. This photo by Cock Reijnders was taken from Internet Bird Collection. I also saw the northern hemisphere Black Storm-petrel which is very like Markham’s but is smaller with a different flight action.

 

hornbys-sp-from-pininterest

The most striking stormie was Hornby’s (or Ringed Storm-petrel). Its breeding grounds have never been discovered but are thought to be in the Atacama Desert. Photo by Cock Reijnders taken from Internet Bird Collection.

 

img_8431-waved-albatross

But the best bird of the day and one of the top five birds of the trip was this Waved Albatross ….

 

img_8428-waved-albatross

This magnificent bird breeds only on the Galapagos and is one of four albatross species confined to the northern and central Pacific.

 

img_8429-waved-albatross

Waved Albatross is the new last albatross species that I will ever see. I hope to do a blog post on my observations of the world’s albatrosses soon but I need to assemble the photos, some of which are on 35mm slides.

 

img_8582-lima-franklins-gulls

After our return to Lima we had a quick look at this lagoon near the port.

 

img_8588-snowy-egret

As well as expected species like this Snowy Egret ….

 

img_8583-grey-hooded-gull

…. Grey-hooded Gull….

 

img_8587-belchers-gull

…. and this adult Belcher’s Gull ….

 

img_8593-franklins-gulls-for-quiz

…. there were thousands upon thousands of Franklin’s Gulls. Our estimates varied from 20,000 to 100,000 but I made do with the lower estimate.

 

img_8614-franklins-gulls

Franklin’s Gull can be distinguished from the similar but larger Laughing Gull in winter by the partial black hood and prominent eye crescents.

 

img_8601-franklins-gulls-people

The gulls were easily spooked by people getting to close ….

 

img_8603-franklins-gulls

…. but the resultant clouds were quite spectacular.

 

img_8604-franklins-gulls

Franklin’s Gulls are unusual in that they have a complete moult after breeding ( as most gulls do ) and then again in the wintering grounds (a moult strategy shared as far as I know only by Willow Warbler). That said most of these individuals don’t seem to have started the moult yet.

 

img_8610-franklins-gulls-lad

This lad seems oblivious to spectacle behind him.

 

From here is was just a short drive to a hotel for a wash and brush up and then to the airport for the flight home. All my foreign trips are interesting and rewarding experiences but this trip was exceptional in many respects. Peru is one of the most interesting of all Neotropical countries and I hope to return for a fourth visit sometime in the future.
