Churchill on Hudson Bay 2017: Tundra Wildflowers & Landscapes

Though the main purpose of my trip was to photograph and video the birds of the tundra, I also got in a bit of landscape and flora photography. Lapland Rosebay (Rhododendron lapponicum) was by far the most dominant wildflower (actually a dwarf shrub) in the landscape. The showy purple-pink flowers dotted the tundra and edges of the boreal forests. At only a few inches high, it is funny to think of this as the same genus of the much larger Rhododendrons and Azaleas that are more familiar to us in “the south.”

I learned that the Canon EF 100-400mm f4.5-5.6L IS II USM lens makes a pretty darn good macro lens due to its amazing close focusing ability. You’ll see many “telephoto macro” images below using this lens.

I also used the iPhone 7+ for several landscape photos. Post processing them with Snapseed on the phone.

An interesting phenomenon I witnessed was the mirage of icebergs on Hudson Bay. Low floating pans of ice appeared to be giant walls of icebergs or a glacier when viewed through the heat shimmer of midday. [Churchill, Manitoba on Hudson Bay]

Lapland Rosebay (Rhododendron lapponicum) is actually a dwarf rhododendron shrub that enlivens the tundra in early summer (mid June).

The dwarf rhododendron called Lapland Rosebay (Rhododendron lapponicum) is only a few inches tall (3 – 18 inches around Hudson Bay), but it has spectacular purple-pink blossoms. It is in the Family Ericaceae along with other small shrubs including blueberries, cranberries, Leatherleaf, Bog Rosemary, Bog Laurel and azaleas.

Lichen pattern

 


The white flower with red speckled petals is Saxifraga tricuspidata or Prickly Saxifrage (a.k.a Three-toothed Saxifrage), one of the most common Saxifrages in the Arctic. It is a colonizer of bedrock, taking hold in cracks. Its Inuktitut name is kakilahan.


Northern White Mountain Avens (Dryas integrifolia) ?? Not quite sure. The leaves below are not Dryas leaves, but maybe from another flower?


Interesting boulder with more resistant quartz veins.


The tundra is extremely colorful in the fall, but equally so in June in spots.

Northern White Mountain Avens (Dryas integrifolia) is a member of the rose family. It is a circumpolar species and is found across Arctic Canada into Alaska and west through Siberia. It is also found at high eleveations in the Rocky Mountains. This species exhibits “heliotropism” as the flower faces and tracks the sun as it moves across the landscape. This may be more attractive to insects as it creates a warmer microclimate. [Launch Road tundra; Churchill, Manitoba on Hudson Bay]

“Flag Spruce” dot the tundra in clumps such as this. They are shaped by the harsh winter conditions; snowpack covers the lower branches, protecting them from the strong ground winds that carry ice chunks and scour the middle trunk of all its branches. The tip of the spruces still carry needle-bearing branches (the “flag”) as they are above the effects of the ice-scouring forces. [Launch Road, Churchill, Manitoba on Hudson Bay]

You may recognize the blueberry type pink flower of this ground hugging shrub. This is likely a species of Vaccinium but I’m not sure which.


Net-veined Willow (Salix reticulata) is a ground-hugging dwarf willow that span less than the diameter of a quarter on the tundra. [Churchill, Manitoba on Hudson Bay]

Five Hours in a Fen

I was able to combine business and pleasure yesterday (July 1st)… Well, It was really all business and a complete pleasure! I had heard of a bog near Cable, Wisconsin that held many Calopogon tuberosus orchids (Swamp-Pink or Grass-Pink) and I was hoping to get video of their ingenious and devious pollination method (read more below).
This particular peatland is actually classified as a fen. What is the difference between a bog and a fen? Bogs are usually stagnant water with very acidic waters. Fens have some water movement and are more basic in pH and richer in nutrients.
Calopogon tuberosus Swamp Pink orchid IMG_2153 Calopogon tuberosus (Swamp-Pink or Grass-Pink orchid) is a delightful mid summer orchid that grows in the floating mat of bogs and fens. Its flowers are “upside down” as the lip is actually on top. The insect-enticing yellow hairs are just a ruse…They fool insects into thinking that they are pollen-tipped or hold nectar, neither of which is true. If a heavy enough bee comes along, it gloms on to the yellow-tipped hairs and tries to extract some pollen. The flower has a built in hinge that collapses and drops the bee on to the sticky pollen packets below. The startled and frustrated bee flies off to try his luck at another Calopogon, and the scenario is repeated, though this time pollination is completed. Devious and Delightful orchid!

Note that on the middle right flower the hinge has already been collapsed by a visiting bee. Though I got video of several small syrphid flies visiting the orchid, none heavy enough to collapse the hinge paid a visit with my camera rolling. Oh well, a reason to go back!
flag spruce IMG_2207Believe me, I was shin deep in water and sinking fast as I took this image. This is an example of a “flag” spruce… A growth form that is very common in the subarctic lands. The “flag” is the upper branches while the nonexistent middle branches were scoured by winter winds and failed to thrive. The sprawling mass of branches low down on the trunk survived because they were protected by deep blanket of winter snow.

Elfin Skimmer Nannothemis bella IMG_2114Elfin Skimmer male (Nannothemis bella)
A wonderful surprise! Just days after Jim Lind and Dave Grosshuesch found many Elfin Skimmers at the Sax-Zim Bog BioBlitz III (a new species for Sax-Zim!) I got my lifer dragonfly! This is the smallest dragonfly in North America at a tad over 3/4 inch long…and the second smallest in the World (one in China is a bit smaller). The male is pruinose bluish and almost appears to have a clubbed abdomen when in flight.
Elfin Skimmer Nannothemis bella IMG_2087Elfin Skimmer Nannothemis bella IMG_2080Female Elfin Skimmers (Nannothemis bella) are very different than the males. They show a ringed black and yellow abdomen. Both the males and females perch often and only move a short distance when disturbed. These were found hunting around a bog pool mainly on the floating mat.
Pogonia ophioglossoides Rose Pogonia IMG_2048Another orchid was just coming into bloom… the Rose Pogonia (Pogonia ophioglossoides) a delicate beauty of floating bogs. Genus name Ophioglossoides is from Greek meaning “snake tongue,” and I guess you’d have to use your imagination on that one, but the lower lip may resemble a fuzzy tongue to some.
Okanagana Cicada IMG_2134Okanagana Cicada IMG_1949A very exciting find was not one, but two singing Okanagana Cicadas. The male of each species produces a unique sound with their tymbal organs on their abdomen which vibrates and resonates in a cavity inside their abdomen and thorax. The Okanagana’s sound is a fast and steady high-pitched buzz.
Crimson-ringed Whiteface Leucorrhinia glacialis IMG_2146Crimson-ringed Whiteface (Leucorrhinia glacialis) is a bog-loving dragonfly of mid summer.
Lincoln's Sparrow IMG_2000Lincoln’s Sparrow was the most obvious avian bog dweller today, singing its beautiful hollow-can, echoey song from stunted Tamaracks and Spruces. Other birds seen in the bog included Nashville Warbler, Eastern Bluebird, Red-tailed Hawk and Eastern Kingbird. The oak-maple covered hills surrounding the fen held Pileated Woodpeckers, Scarlet Tanagers, Ovenbirds, Red-bellied Woodpeckers, Eastern Wood-Pewees and other deciduous species that would have no use for a bog.
Rhynchospora alba White Beaksedge rush IMG_2019Rhynchospora alba or White Beakrush (or White-beaked Sedge) was very common surrounding the bog pools.
Sarracenia purpurea Pitcher Plant leaf IMG_1900Is there a lovelier leaf in the world? Yes, the “pitcher” of the carnivorous Pitcher Plant (Sarracenia purpurea) is actually a modified leaf. Inside a deadly mixture of rain water and enzymes can drown and dissolve the unwary insect. The plant is able to absorb important nutrients such as Phosphorous from the tiny carcasses with special cells low inside the pitcher. Good thing these guys aren’t six feet across!
Utricularia cornuta Horned Bladderwort IMG_1952One more carnivorous plant was super-abundant at this fen, Horned Bladderwort (Utricularia cornuta). The related Common Bladderwort is a predator that has dozens of tiny bladders on its underwater leaves. The hair-triggers on the bladders are set off when a tiny aquatic insect blunders by and sucked in to the bladder in a rush of water. The bladder now becomes a tiny stomach and the insect is dissolved by the plant.
