Iceland

In 2016, my daughters asked me if I would pay an exorbitant amount of money to drive them hundreds of kilometres around Iceland whilst they sit in the back listening to music on their headphones eating crisps. How could I refuse! At the end of July we set off.
We arrived in the capital Reykjavik, the only town of any size in iceland, with a population of around 130,000, seen here from the top of the Hallgrimskirkja.
About 100 km to the north is the Snaefellsnes peninsula. We stayed at the Freezer Hostel and Cultural Centre in Rif, at the end of the peninsula, where we were surprised with great beer and live music.
There are two ways to visit Iceland; clockwise or anti-clockwise. Like most people, we chose to tackle a part of the former. First stop, the area packed with the major tourist sites - linked by what is known as the Golden Circle.
Around 50 km to the east of Reykjavik lies Thingvellir, the site of the Icelandic parliament until 1798 (a thing originally meant an assembly). Here one can walk along the rift valley that marks the Mid-Atlantic ridge - the barrier between the North American and Eurasian tectonic plates. Not to be sniffed at.
Further east is the Haukadalur Valley, where one can watch the Strokkur geyser erupt - which happens regularly every few minutes up to heights of around 15-20 metres.
And a little further on, the Gullfoss falls.
What Iceland lacks in humans, it compensates for with birds. It is the height of summer, and the migratory birds that fly north to breed are in full residence. A number rest in the inland grasses with fresh water. The Whimbrel (Numenius phaeopus) spends the winter in Africa, and breeds in sub-arctic Europe and Asia. It can be told from the Curlew by its shorter bill and pronounced eye stripes.
The Black-tailed Godwit (Limosa limosa) turns a magnificent rusty red in the summer. It can be seen all year round in mainland Europe, but the islandica sub-species only breeds here.
Scaup (Aythya marila) spend the winters in northern Europe, Asia and North America, and go to the arctic to breed.
We (I) drove along the south coast.
Water from the surrounding highlands spills down as waterfalls. This is Seljalandsfoss. Look carefully and you will see a Fulmar (Fulmarus glacialis) flying at the top of it.
Fulmars normally breed on sea cliffs, so I didn't expect to see one settled inland - especially next to a waterfall. They look like gulls, but are not - and can be told from the blue 'tubes' at the base of their bills, which they use to remove salt.
This is Skogafoss.
Further east on the coast, by Solheimasandur, there is the wreck of a US navy C-117D plane which crashed in 1973. It has become a gruesome tourist attraction, though at least no one died in the crash. It is at best an excuse for a walk to look for birds.
At the Dyrholaey promontory, basalt rock has been carved by the sea.
On the natural steps of the cliffs, formed by basalt columns, is a colony of Kittiwakes (Rissa tridactyla). 
The adult looks everything like what you'd expect a gull to look like (grey and white with a yellow bill) but it has dark black legs.
The young are altogether more fancy, with black markings on the head and wings.
It's feeding time, and maybe the bright red tongue of mum is a good cue.
Some Guillemots (Uria aalge) have muscled in on this ledge, with no intention of keeping to their side of the bed.
Looking west from Dyrholaey, across Reynishverfi beach, more accessible basalt cliffs can be seen.
We called in so that I could do my famous kittiwake impression.
It's always a joy to see Arctic Terns (Sterna paradisaea) - birds which breed in the north of the northern hemisphere, spend winter in the south of the southern hemisphere, and migrate the huge distances in between.
Waders were searching for food in the mud. Redshanks (Tringa totanus) are resident over much of Europe, but the sub-species T. t. robusta comes to Iceland to breed.
These Ringed Plovers (Charadrius hiaticula) are of the psammodroma sub-species, which breeds in Iceland, Greenland and northeast Canada, and spends the winter in west Africa.
Here is one of their chicks.
A young Dunlin (Calidris alpina), presumably born in Iceland, will soon leave for more southern lands.
Turnstones (Arenaria interpres) spend the winter in Iceland, but do not breed there - these have probably just returned from Greenland, still in their bright breeding plumage.
Purple Sandpipers (Calidris maritima) prefer to hunt on the rocks. They spend the winter in the north of Europe and North America, and breed in the arctic - though Iceland and northern Scandinavia have resident populations.
The Red-throated Diver (Gavia stellata) is another arctic breeder, at which time they develop a rusty stripe on their throats.
A mother keeps her chick close at hand...
...whilst this older youngster is more independent.
Further east again, to the point where the Breioamerkurjokull glacier flows out of Iceland's largest permanent ice sheet to meet the sea at a lagoon called Jokulsarlon.
I was overwhelmed by the beauty of the forms and hues, and took far too many photographs.
The kittiwakes and arctic terns also love it here.
Female Eiders (Somateria mollissima) swam around in the lagoon with their chicks. They are really northern ducks, and nest here in colonies of closely related individuals. They pluck downy feathers from their breasts to line their nests, which, once vacated, are famously harvested by the islanders for the filling of pillows and quilts.
The males, having mated, had lost their bright white and pistachio green and salmon pink pastel plumage - and had reverted back to their monochrome 'eclipse' form.
On the rocks hopped another really northern bird, the Snow Bunting (Plectrophenax nivalis). It is an arctic breeder, with yearly resident populations only found in Iceland (the insulae sub-species) and Alaska. The male has a pure white head and breast in the breeding season, but this one looks like it is already losing those feathers and changing back into the brown of winter.
The female was busy feeding her chick.
All these birds need to keep a watchful eye, for on the beach sat a Great Skua (Stercorarius skua). They are aggressive and fearless, and have no qualms about snatching a bird in flight for a meal.
But our tour was at an end. It was time to turn around and go clockwise back from whence we came. Driving back over the bridge I saw a Hooper Swan (Cygnus cygnus), another arctic breeder that is only resident all year in Iceland. Then I looked at the two chicks - lanky and a little scruffy, with pink noses, but with the promise of elegance, sitting in the back of the car listening to music on their headphones and eating crisps.

Vietnam

At the end of December 2013 our family went to Vietnam.
We arrived in the capital, Hanoi, in the north of the country.
After dinner in a restaurant by the train station, we boarded a sleeper to Sa Pa.
Sa Pa lies in the mountainous area between Lai Chau and Lao Cai on the border with China, reached by travelling 300 km up the Red River north-west of Hanoi.
We woke up at our destination in the morning mists.
The surrounding hills are home to a number of ethnic groups. The largest are the Hmong and the Yao, numbering around 4 million each  -  most living over the border in China, but thier ranges extending into Vietnam (and for the Hmong also Laos). Nearly 2 million Tay people and around 70,000 Giay people live in north Vietnam. These 'hill' peoples are further divided into smaller groups with their own languages - nothing creating diversity better than the isolating effect of mountains and valleys. They live by growing crops, mainly rice, on sloping terraces.
No rice is grown in the cold mountain winters, and time is rather spent maintaining the terraces...
...cutting fire wood...
...or watching cock fights.
The clothes of the people here are usually blue, and often so dark as to appear black. The dye used for this is Indigo (Indigofera tinctoria), a plant of the pea family.
The Yao women (Dao in Vietnamese) wear colourful embroidery over their indigo, and sport very dashing bright red hats and headscarves.
We stayed in the wooden house of this Dao couple.
We also dressed in indigo, to blend in.
Our hosts also kept pigs, which were often seen running around the rice paddies.
Dinner was cooked over an open fire in the middle of the room - and hanging over our heads, porc being preserved in the rising smoke. Heaven.
We then crossed to the opposite side of north Vietnam - to Ha Long Bay, about 150 km east of Hanoi. A UNESCO world heritage site, and big tourist attraction, it contains around 2,000 mostly limestone islets.
We spent a couple of days touring on a boat. In the evening all these boats congregated at a sheltered spot to spend the night.
Despite the concentration of tourists boats, it's still possible to see the age old sight of fishing boats going out to sea, but with the unusual backdrop of karst peaks.
Cuttlefish are a speciality here.
And no number of tourists can take away the wonder of Sung Sot cave - the creative power of the sea dissolving limestone.
We then flew south to the second city of Vietnam, Ho Chi Minh City - named after the founder of the modern country, who fought against Japanese, French and American occupations, but who died six years before the North Vietnamese capture of the city (then called Saigon) and the final unification of an independent country.
Ho Chi Minh City is a stone's throw from the delta of the mighty Mekong river.
We travelled up river and just enjoyed watching the local businesses pass by.
Back on land, we watched the staple food of rice being loaded off barges and weighed.
Then it was onto bicycles, as the best way to tour the local villages.
Visiting local markets is a great way to have a snap shot of the culture and biology of a region. A display of vegetables also provides the aesthetic delight of shapes and colours - here some bright green bitter melons are surrounded by earthy root vegetables such as sweet potatoes, yams, and yam beans.
Jackfruit (Artocarpus heterophyllus) belongs to the fig and mulberry family.
Duck is a favoured meat in south-east Asia.
Fish has to be a staple on one of the worlds largest river deltas.
Eating Ricefield Rats (Rattus argentiventer) provides a great source of protein, and reduces a crop pest.
But eating wild animals in these wetlands must also be sustainable. I guess the frog populations may be resilient to harvest.
Snakes I can imagine could be more under threat.
Wild birds in cages always saddens me, whether or not the populations are threatened. Here we see Slaty-breasted Rails (Lewinia striata)...
...Water-browed Crakes (Poliolimnas cinereus)...
...and Oriental Darters (Anhinga melanogaster).
On a more joyful note, it seems we had arrived during the wedding season. A great excuse to dress up... 
...and for drunk uncles to show off their moves.
The road eventually led to the town of Can Tho, and back to the scooter bustle that is Vietnam.
In one of the schools children practiced their martial arts under the watchful eye of Ho Chi Minh.
With night fall the crowds emerge out into the cool air to mingle in the street markets...
...and to enjoy some entertainment in the park.
Soon it was time to escape the crowds again, and go back out into the bush. Cat Tien National Park, 150 km north of Ho Chi Minh City, is one of the largest areas of lowland tropical forest left in Vietnam. 
A consultant for my old company, retired from Imperial College in London, has set up a wildlife lodge there. We crossed the river to the park to spend a few days with him.
Many hotels provide a cheesy reception - a glass of cheap wine or some dead flowers on the pillow. At Forest Floor Lodge we had a real naturalists reception, a snake in the bedroom - a Radiated or Copperhead Ratsnake (Coelognathus radiatus). I managed to get a shot of it before it was caught. 
A stroll in the forest
Flitting about, the Common Grass Yellow (Eurema hecabe)...
...and Great Eggfly (Hypolimnas bolina).
We came across an agamid, one of my favourite groups of lizards. It is a Crowned Pricklenape (Acanthosaura coronata). They look so elegant...
...but are very grumpy.
