The Spruce Bog Boardwalk is a trail that runs through (and also, over) the fascinating ecosystem of a northern bog. Bog “soil” is composed of decaying plant matter known as peat, and this substrate is extremely acidic, allowing only certain types of plants to grow within these wetlands. The ones that do are hardy species and the most conspicuous is the only species of tree to thrive here: the Black Spruce (Picea mariana). Black Spruce are scraggly trees, but they are trees which live in such a difficult environment that they are truly impressive.
Certain portions of the Spruce Bog trail feature beautiful wildflowers and insects, but on this occasion I rushed through the trail for personal reasons*, only stopping to snap a picture near the very end of the trail. The bird I photographed is related to the Eastern Kingbirds (Tyrannus tyrannus) that I saw perched near the Opeongo Lake Road, it was an Eastern Phoebe (Sayornis phoebe).
*essentially it had to do with a small tired person accompanying me
Eastern Phoebes are part of the Tyrannidae Family of birds and if you’re thinking that sounds like a Family of Dinosaurs then I’d like to mention briefly that you would be 100% correct. Tyrannidae is a Family of Dinosaurs, because ALL Birds are Dinosaurs that have survived the mass extinction of other branches of the Dinosaur family tree (including the branch called Tyrannosauridae, ie Tyrannosaurus and kin, which is the one you were probably thinking of). Tyrannidae (the Tyrant Flycatchers) is not especially close to the Tyrannosauridae (the Tyrant Dinosaurs) of course, but they are both included within Dinosauria.
Anyway, another extant (as opposed to extinct) Dinosaur species that I observed was on the Logging Museum Trail, floating swiftly between Water lilies: the Hooded Merganser (Lophodytes cucullatus). The photographed individual (a female, I believe) isn’t raising its headfeathers into a crest, which is where it’s name of “hooded” merganser comes from. These ducks nest in tree cavities (so not just Wood Ducks do this… huh…) using old Woodpecker nest cavities most of the time (Tozer 2012).
Two wildflower species caught my eye on the same trail that day. One was a relative of the Steeplebush (Spiraea tomentosa) (see Peck Lake observations), being part of the same Genus Spiraea. White Meadowsweet (Spiraea alba) is more popular with Butterflies than the Steeplebush, as it produces more nectar than the former (Runtz 2020).
The other wildflower was Virgin’s-Bower (Clematis virginiana) and it was being attended to by Blackjacket Wasps (Vespula consobrina).
Let the Blackjacket Wasps serve as a teaser for the final chapter of my Algonquin observations: Spruce Bog: the Reckoning, in which I return to the Spruce Bog trail and take a very long time to walk it, Macro Lens equipped! Move over Birds and Flowers (well, there will be some flowers)! It’s finally time for the Insects to take their usual place in the spotlight of my camera!
Morning in Algonquin Park is a wonderful thing. Monday August 2 was cool and the air was filled with heavy mist that blurred the edges of the tall Red Pines of the Pog Lake Campground as I set out for an early morning hike in the hopes of some interesting sightings.
I had decided to head to the Peck Lake Trail, because as the name implies, it circles a Lake and I thought it might afford some nice views in the morning mist, and some rare creatures to photograph. The first Bird I photographed on the trail was one I had never seen before (or at least never captured with my camera): the Blue-headed Vireo (Vireo solitarius).
As I came upon an opening in the woods I was rewarded with an excellent view of the misty lake in the morning, with its signature Algonquin Park inhabitant: the Common Loon (Gavia immer). No matter how many times I hear that undulating call or see this distinctive bird dive beneath a lake to reappear surprisingly far away, I will be amazed. In Ancient Life of the Great Lakes Basin it’s mentioned that Loons are an ancient group of birds with fossils being found in the Cretaceous Period, contemporary with non-avian Dinosaurs. “One gets goose bumps imagining the characteristic tremulo calls and haunting wails of the loon song echoing over the lakes and swamps of the Cretaceous over 60 million years ago.” (Holman, 1995). We will likely never know if these ancient members of the Loon lineage (Gaviiformes) had similar calls, but the image is certainly a beautiful one.
While admiring the majesty of the Loon on the lake, I was distracted by a series of strange noises from above me in a tree. The noises were certainly a bird, but I had no idea what sort until the bird took off and flew away with heavy wingbeats. The bird in question was a Common Raven (Corvus corax) and they’re renowned for being diverse vocalists. One of the vocalizations they don’t make is a “caw”ing sound, unlike their relatives and the species often confused with them: the Common Crow (Corvus brachyrhynchos). The power and size of a Raven impress me every time I see them, enhanced always by my readings of Bernd Heinrich who has devoted much time and energy into exploring these magnificent birds’ ecology and behaviour (see Mind of the Raven, Ravens in Winter, and most Bernd Heinrich books mention Ravens at one point or another).
As I continued down the trail, I was once again startled by the movements of a rather large Bird except that this time the Bird was on the ground, directly in front of me on the trail rather than flying away across the treeline. I am quite disappointed by how my pictures of this bird turned out, and I’ll blame the bird’s constant movement and the poor lighting conditions of a shaded woodland in the early hours of the morning for their poor quality. The Bird was a Ruffed Grouse (Bonasa umbellus), one of two Grouse species found in Algonquin Park.
Back to the trees, I spotted another Bird, one I had already photographed during my trip here, though this particular individual looked rather different. It was a Yellow-rumped Warbler (Setophaga coronata), though the pattern is quite obscured on this individual. I believe it’s either a Juvenile or a Female since it doesn’t carry the distinctive colours and patterns of the mature males (see my photos of a Male in the first part of my Algonquin Observations series).
Along the edges of the lake, there were some beautiful flowers growing so I decided to take some pictures of them as well. The plants were Steeplebush (Spiraea tomentosa) which prefer to grow in wet areas. Their flowers are attractive to Beetles and Bees, and not as attractive to Butterflies because they contain little nectar, but have masses of heavy pollen (Runtz, 2020). On this chilly morning, neither Insect group was out and about.
A part of the trail crosses a marshy area via boardwalk. I crept across this boardwalk, listening closely for the movements of animals, hoping to hear the movement of an elusive mammal or bird. Instead, by listening so carefully I was startled several times by creatures to either side of the boardwalk, making their swift escapes known with a loud squeak. The creatures were Frogs, likely all of them part of the American Water Frog genus Lithobates (which includes the Green Frog (L. clamitans), the American Bullfrog (L. catesbeianus), and the Mink Frog (L. septentrionalis), as well as many others, but these three are the most common that I’ve encountered in Algonquin). The only one that sat still enough for a picture was the one below, which I believe is a Green Frog because you can just maybe make out a ridge of skin (called the dorsolateral fold) which runs from its eye down part of its back (Harding and Mifsud, 2017). This feature distinguishes it from the similar-looking Bullfrog.
The final observations on the trail were several Spider webs caught beautifully in the early morning light. I recently read a passage in the book Spider Communication which gave me a new appreciation for Spider Webs. “Many spiders have compensated for the absence of a suitable substrate over which a vibratory signal can be conducted…by extending the perceptual range of the legs with a silken structure…Suddenly the radiating shape of the web takes on a new meaning for the observer: the web extends the perceptual range of the sense of vibration from about 15 mm to more than 500 mm” (Witt, 1982). Not only do they act as prey-catching snares, but they are sensory extensions of the Spider, extending their senses beyond the limitations of their small bodies. Fascinating, beautiful constructions.
Yet MORE Algonquin Observations to come! More Birds, More Wildflowers, and eventually the Invertebrates will have their usual spotlight!
