Mid-summer scenes

Mid-summer, it’s the time when fruits are ripening, profusions of flowers light up backyards and prairies, and we see lots of birds, butterflies, and bees everywhere.  It might be hot and sticky, but this is the time we’ve been thinking about on those cold winter days.

Monarchs have made it to Minnesota by July, and begin laying the generation of butterflies that may be the ones to migrate south in a couple of months.

Lake water warms up, and mats of water lilies and duck weed clog the shorelines.

Sandhill Cranes may have chicks following them around through the prairie meadows, and occasionally you see and hear them fly overhead.

Black morph, Tiger Swallowtail butterfly

The black morph of the Tiger Swallowtail butterfly has been visiting the backyard garden this week. It must be relatively newly emerged, with no bites in its wings yet.

What’s not to love about mid-summer days in the Minnesota backyard?

Pollinators, large and small

The purple flowers are blooming in my garden: spiderwort, weedy creeping charley, iris, bellflower, mountain cornflower, and lovely blue wild indigo. And there are a few bees around, doing their best on the limited amount of nectar and pollen available so early in the summer.

bumblebee nectarine on false wild indigo

This queen(?) common eastern bumblebee approaching a flower of the false wild indigo is faced with the task of getting to the nectar at the base of the flower through what appears to be closed “doors” (lateral petals) of the flower.  She is really too big to fit.

bumblebee nectarine on false wild indigo

Her weight is sufficient to separate the wings (lateral petals) of the flower, so she can poke her head (and tongue) deep into the base of the flower where there is nectar.

bumblebee nectarine on false wild indigo

The two halves of the keel petals at the bottom of the flower also separate under her weight, exposing the anther pollen and the bright, orange-yellow, three-pronged stigma (female receptive surface). Pollen she carries on her legs and body from another flower will stick to the stigma and travel down its tube to fertile ovules in the flower ovary to make seeds.

bumblebee nectarine on false wild indigo

Pulling away from the flower before flying to the next one, you can see the contact between bee and pollen.

Lady Bumble made the rounds of the newer flowers at the top of the raceme, working her way from oldest at the bottom to newest opened at the top, and then on to a different spike of flowers.  But the small solitary bee working these flowers had an entirely different strategy.

Solitary bee on false wild indigo

You can see how tiny this little bee is in comparison to the flower.  It preferred visiting the older flowers, whose petals were drooping and not fitting as closely together as in the younger flowers. 

Solitary bee on false wild indigo

Now, how to get inside the flower to reach the pollen? Squeeze through the tiny crack between petals.

Crawling inside finally, the bee disappears for a few minutes before crawling out and making its way to another, older flower.

Older flowers may not produce much nectar, But smaller bees don’t require as much as large bumblebees anyway. And perhaps pollen collection was of more interest to this tiny bee.

a rare beauty

Lady’s Slipper Orchid may be one of the slowest growing plants in the world, taking 6 to 11 years to reach the size when it first flowers.  But when it does, we rarely fail to notice, and marvel at its color and structure.  All this from a minuscule seed the size of a speck of dust!

(Yellow) Lady’s Slipper Orchid

I was quite excited when my neighbor showed me the Lady’s Slipper Orchids growing in his back yard.

(Yellow) Lady’s Slipper Orchid

The name, of course, comes from its shape, the swollen labellum appearing to be a dainty shoe for a pixie-sized lady.

Like many showy flowers, orchids are dependent on pollinators to transfer pollen from one plant to another.  But Lady’s Slippers and another 40 percent of the 20-30,000 orchid species of the world attract their pollinators with color, fragrance, or even by mimicking the shape of a female pollinator of the same species, and offer no nectar reward.  How do they get away with “cheating” their pollinators and still ensuring pollination success?

By “inviting” them in, trapping them momentarily, and then providing a narrow escape route that forces the pollinator to squirm by sticky pollen sacs on the anther as they exit.  Here’s how it works.

One way route through the (Yellow) Lady’s Slipper Orchid

It’s a one way route through the flower, in through the enticing, colorful and fragrant labellum, and out through the slit in the back, top of the flower.  When they visit the next Lady’s Slipper flower, they rub the acquired pollen onto that flower’s stigma.  Voila, Pollination!

Bumblebees are too large to fit through the narrow slit at the top of the flower, so they exit the way they came in.  Smaller bees land on the hairy pad at the back of the inside surface of the labellum, crawl toward the light showing at the top, and squeeze themselves through the slit, as shown on the video below.

Practicing this deception seems risky, especially since bees are less prevalent today than they once were.  This rare beauty, once found throughout North America, Europe, and Asia is in decline world-wide.  It suffers from being over-collected, loss of habitat, and now —perhaps, a decline in the numbers of its pollinators.

The Rift Valley of Iceland

Mid-ocean ridges on the ocean floor encircle the globe like the seams of a baseball.  Along their more than 40,000 mile length, magma seeps upward, building chains of underwater mountains and pushing continental land masses riding on massive tectonic plates further apart.

Mid-ocean Ridges, Wikipedia

The mid-ocean ridge system, Wikipedia.

Iceland is one of the few places on earth at which one can see the evidence of this activity, as the entire island sits right on the mid-Atlantic ridge and was formed from the volcanic activity at that site over the past 24 million years.

Mid-Atlantic ridge in Iceland

The best example of activity of the Mid-Atlantic ridge is at Þingvellir (Thingvellir) National Park, just 25 miles northeast of Reykjavík. Iceland Magazine.

Þingvellir (Thingvellir) National Park, Iceland

Separation of the North American and Eurasian plates can be seen in the fissures and cracks that develop along the mid-Atlantic ridge in Iceland.

What an unusual sight this area is, as land mass is added to Iceland at a rate of about 2.5 cm (one inch) per year.  The land here forms crumpled and jagged cliffs of rock surrounding flatter rift valleys.

Þingvellir (Thingvellir) National Park, Iceland

In Þingvellir National Park, a path takes visitors right down the rift between the North American (background) and Eurasian (foreground) plates.

The grounds at Þingvellir (Thingvellir) National Park were a sacred spot for the Norse and Celtic people that settled the island in ninth century AD.

Þingvellir (Thingvellir) National Park, Iceland

A parliamentary assembly occurred for two weeks here each year from 930 to 1798 AD. An elected law giver would recite all the laws, new laws were debated, and merchants traded their goods.

Thousands of people attended these annual gatherings, to participate in the parliament as well as the trade of various goods.  Temporary homes were constructed, but no permanent buildings were erected on the site.

Lava flow, Þingvellir (Thingvellir) National Park, Iceland

Recent lava flow is gradually broken down, allowing plants to colonize, but this Rift Valley is really relatively sterile and devoid of life.

There are a few birds, but most of them rely on lake or lakeshore habitat instead of barren lava fields for food and nest sites.

A pair of Tufted ducks can find enough aquatic invertebrates and vegetation to sustain them in the lake.

Graylag geese

Graylag geese seem to be found everywhere in Iceland, so cold water and barren lava fields are no barriers for them.

Þingvellir (Thingvellir) National Park, Iceland

However, interesting biological changes have been going on in the lake formed at the end of the last Ice Age (10,000 years ago), when it was cut off from the sea.

Icy cold water that trickles into the lake seems to be the perfect habitat for growing king-sized brown trout that weigh up to 30 pounds, and Arctic char found open niches in the lake’s varied aquatic habitat, allowing them to split into six different species during the past 10,000 years.  Great news for fishermen everywhere that come to fish here and in the many fresh-water streams throughout the island that attract salmon on migration.

 

Waterfall extravaganza

There are lots of spectacular single waterfalls in Iceland, but Hraunfossar is a real waterfall extravaganza of 900 meters of water falling over rocks.  I’m standing in one spot, trying to capture the entire length of the waterfalls over the next three images.

Hraunfossar waterfalls, Iceland

Hraunfossar waterfalls form along a stretch of lava bordering the Hvítá River. 

Hraunfossar waterfalls, Iceland

Water from the melting Langjökull glacier streams over a lava field formed when a volcano beneath the glacier erupted about 800 A.D., before Iceland was settled The lava field above the shrubby birches is quite visible in this shot.

Hraunfossar waterfalls, Iceland

Clear, filtered water from the glacier flows between lava layers and turns the river a lovely turquoise blue color. The glacier is just barely visible below the clouds in the distance.

Hraunfossar waterfalls, Iceland

You can find close-up views of these waterfalls in most travel ads for Iceland, yet there were hardly any tourists here.

Hraunfossar waterfalls, Iceland

Another photo favorite of Iceland ads…

Redwing thrush, Hraunfossar waterfalls, Iceland

The only birds we saw here were the Redwing thrushes, which had to sing really loudly to be heard over the roar of the waterfalls.

Lava field at Hraunfossar waterfalls, Iceland

The lava flow is still bare rock in some places. In others, mosses and shrubby birches have covered the top of the lava field.

Hraunfossar waterfalls, Iceland

Further upstream, the lava gorge narrows, and the water thunders through in a giant roar, creating the waterfall known as Barnafosar, the children’s waterfall.

Barnafossar waterfalls, Iceland

The waterfall is named for two children who may have perished when they fell from an arch that used to span the Barnafossar waterfall. The story goes that the children’s mother had the arch destroyed so that no other children would suffer the same fate.

Barnafossar waterfalls, Iceland

The water here flows at an average of 80 cubic meters per second, but can reach 500 cubic meters per second when the river is in flood state. In comparison, the average flow of the upper Mississippi River out of its origin at Lake Itasca (a comparable sized stream) is 6 cubic feet per second (=0.17 cubic meters per second).

Birds, and more birds, on the Snaefellsnes peninsula of Iceland

Iceland may have an impoverished bird fauna, compared to what one can see in the U.K. or Europe, but it more than makes up for it with great numbers of the species that are present.  For the bird photographer, this makes it easier to get some good photos.

A really good place to see seabirds is at the cliffs at Arnarstapi on the southern side of the Snaefellsness peninsula.

Shag on a nest, Arnarstapi cliffs, Iceland

Shags weren’t very common here, but a couple of them had carved out some space low on the cliffs.

Kittiwake gull, Arnarstapi cliffs, Iceland

Kittiwakes are the only gull that nest on cliffs. They were typically found in great numbers lower on the cliff than the fulmars, which are bigger birds and are more aggressive toward everything that approaches their space.

Down on the shoreline below the cliffs were several species of shorebirds, foraging in the sand and rocks right at the edge of the water.

Iceland Gulls, Snæfellsnes Peninsula, Iceland

Iceland Gulls are rather small, with pink feet, and bright yellow bills. They actually don’t breed in Iceland, but instead in Greenland and arctic parts of Canada.  Apparently they are still fattening up for spring breeding before migrating.

Knots, Snæfellsnes Peninsula, Iceland

A lot of Knots. These small birds look like every other shorebird in the winter, but have bright chestnut back and breast in their breeding plumage, which is why some call them “red knots”.  It’s another arctic breeder in Canada, Europe, and Russia.

Also foraging along the shoreline at other points along the Iceland coast were Sanderlings, Ruddy Turnstones, Purple Sandpipers, Ringed Plovers, and Red Shanks.  These species were exploring the seaweed that had washed up on shore, and the crevices between rocks along the shore, turning things over or probing into sand to find small invertebrates there.  They will all fly on from here to their arctic breeding sites in Europe and Russia.

Red Shanks are well named, as their red legs make them easy to spot.

Arctic Tern with fish

Arctic terms were flying overhead at Arnarstapi above the grassy meadows, some carrying fish.  This species is the longest distance migrator among all animals, flying from its Antarctic home in our winter to breed in the Arctic in our summer, and then back again, a round trip of about 44,000 miles.

Harlequin duck pair, Snæfellsnes Peninsula, Iceland

Harlequin ducks are at home in the open ocean, but they breed in cold, fast moving streams in northern North America, Iceland, and Greenland.  The outlandish color pattern of the breeding male gives the duck its name.

Harlequin duck pair, Iceland

Unfortunately, numbers of these handsome ducks are declining rapidly in North America, due to loss of habitat on cold, northern rivers and oil spills. I hope they fare better in Iceland.

The highlights of our bird sightings was finding a breeding pair of Red-throated Loons and Horned Grebe on some of the small lakes that dot the Iceland landscape.  Brilliant colors of these birds light up the infamously gray, cloudy, rainy landscape here.

The amazing Snaefellsnes peninsula of Iceland

The Snaefellsnes peninsula in western Iceland is known for its dramatic landscapes, but nothing can prepare you for just how dramatic and all within a few miles of each other.

Our first stop at Budir to see the Black Church surprised us with some stunning mountain scenery as well.

Near Budir, Iceland

Mossy lava covers much of the ground on this peninsula.

Mossy lava, Snaefellsness peninsula

Mossy-covered lava is really a composite of over 130 species, including several species of ferns.

Black Church, Budir, Iceland

This iconic church sits by itself on the edge of the coast, which is probably why it is so well photographed.  It’s not unusual to see black-painted houses in Iceland; perhaps they draw and maintain more of the heat in this frozen landscape.

Sea cliffs at Arnastapi, Iceland

Sea cliffs at Arnarstapi just west of Budir were particularly interesting because of the exposed columns of basalt at their base.  New and interesting-looking lava formations are scattered along the coast, as you hike on a cliff side trail from Arnarstapi to Hellnar.

A picnic table overlooking a natural arch lava formation at Arnarstapi — the perfect stop for lunch.

Route 54 to Olafsvik, Iceland

Route 54 took us over a mountain pass from the south coast of the peninsula to the north side. There was stunning mountain scenery all along the way, making me think I was at 12000 feet in the Rockies.

Route 54 to Olafsvik, Iceland

Waterfalls and mountain peaks, what more could you want?

North coast, Snaefellsness peninsula, Iceland

Finally along the north coast of the peninsula, we spied a long stretch of black sand beach, and the coastal peaks that dot the landscape here.

Kirkjufell, Iceland

Another iconic spot, beloved by photographers, is the Kirkjufell peak that rises steeply from the ocean to form a peak from one view, and a long exposed ridge resembling a cathedral from a side view.  Nearby is the waterfall named for the peak and often photographed with it, if you have the time for a bit of a hike.

Grundarfjördur, Iceland

Turning around from the view of Kirkjufell, you see the lovely harbor area of Grundarfjördur, a fishing village on this north coast.

Grundarfjördur, Iceland

And of course there are lots of birds to find and identify along this coast, but that’s the subject of another post.

 

This scenery is stunning!

Iceland continues to amaze.  The vistas are panoramic and huge, the mountains spring up out of absolutely flat lava fields or grasslands, there are steep sea cliffs with nesting sea birds for the bird lover to enjoy, and there seems to be a waterfall around every corner.  We haven’t had many sunny days (maybe one), but the weather is constantly changing, so if you wait a while at one spot, you can get a decent photo.

Waterfalls and glaciers in Iceland

Some of the most spectacular sights in Iceland are of course its glaciers and their waterfall outflows.  Even on cloudy, foggy, rainy days like the one we drove the southern coast, the sightseeing is pretty spectacular.

Myrdalsjokull glacier, Iceland south coast

Myrdalsjökull glacier is the fourth largest glacier in Iceland, covering an area of 600 square kilometers.

Myrdalsjokull glacier, Iceland south coast

The tip of the glacier used to be well beyond these ice floes to the left.  Like other glaciers around the world, this one is melting at a rapid rate, sending torrents of water over impermeable lava cliffs to the sea.

Glacial outwash, Myrdalsjokull, Iceland

Beneath the Myrdalsjökull glacier is an active volcano, Mt. Hekla, which every now and then sends a charge of hot magma upward, melting tons of ice, and sending a flood of water at 100-300,000 cubic feet per second! down this glacial outwash plain.

Skogafoss waterfall, Iceland

Skogafoss waterfall is one of the outlets of glacial melting. Measuring 50 feet wide and 200 feet in height, it is one of the largest waterfalls in Iceland.  On sunny days, its spray creates rainbows, but not on the rainy day we visited.

Waterfalls on southern Ring road, Iceland

Waterfalls, like Seljalandsfoss, are a common sight on the southern part of the Ring road in Iceland.  The view from behind the waterfall is a must, but we missed it unfortunately.

But these beautiful waterfalls are small potatoes compared to the powerful volume of water that has shaped the terraces of Gullfoss, formed from the melting of Iceland’s second largest glacier, Langjökull.

Gullfoss, Iceland

The Hvita river that drains the Langjökull glacier pours 4900 cubic feet per second down the waterfall and canyon below it in the summer.  Standing next to this roaring torrent is deafening, and can be a little wet as well.  Those stick figures on the distant plateau may be wet tourists.

Gullfoss waterfall uppermost falls

The view from the uppermost terrace of 4900 cubic feet per second of water coming straight at you!

A new vista

Farewell, Scotland.  Hello, Iceland — a new vista for us.  And what a unique and interesting place it is.  Here are a few of the vistas we’ve seen in the last two days.

River Hotel, Hella, Iceland

The view from our lodgings at the River Hotel in Hella, about 50 miles east of Reykjavík on the Ring road.

With 18 hours of daylight, who can sleep at 5 a.m.? The birds are up and active on the river at this hour, so I am too.

Thingvellir National Park, Iceland

Iceland’s volcanic origin is evident wherever you go, especially at Thingvellir National Park, Iceland’s equivalent of Yellowstone.

Thingvellir National Park, Iceland

Thingvellir National Park, Iceland

River runoff from the glaciers that cap the central portion of the island are numerous. Excellent fishing here, judging from the 3-foot mounted specimens on the walls of our lodge at the River Hotel.

Thingvellir National Park, Iceland

Neat houses are tucked into hillsides and along waterways, usually far from each other. It’s a mostly deserted landscape, free of human influence…

Icelandic ponies

With lots of Icelandic ponies in open fields.

And of course, the birds — it’s nesting time in the arctic, and the birds are unusually active in these long daylight hours.  There are limited numbers of species breeding on this small island, but lots of individuals of those species present.

Whooper swans, Iceland

Not just one, but a whole herd of Whooper Swans, in the middle of a grassy field, lined up, pairing off? We’ve found big flocks of these huge birds in several areas on our drive around the south coast.
