Another Cedar Waxwing post (there was a previous one recently here). It is hard to resist these photogenic birds with their punky hairdo. They are easily found down in the Whitemud Ravine during the summer as they seem to like to hang out by streams and ponds. They are sociable and tend to be seen in flocks. This individual was down at a small pond together with 3 of its mates. Cedar Waxwings have a bit of a reputation for enjoying munching on berries (such as Mountain Ash berries) that are overripe and have begun to ferment. As it turns out, fermented fruit has the same effect on birds as it has on humans. I guess by this measure they would be considered the party animals down of the creek. So there you have it folks – humans get their fermented fruit on Whyte Ave and Cedar Waxwings get it down by the creek. On this sunny summer day, however, these particular waxwings were on their best behaviour.
Perched on a dead branch jutting out over the pond was an Eastern Phoebe with its distinct big-head and white “scarf” around its neck. Phoebes belong to the Tyrant Flycatcher family and with their short beaks they specialize in catching flies and other flying insects. The Tyrant Flycatchers are a family of passerine birds occurring throughout North and South America. It is considered the largest family of birds, with more than 400 species. That could be a challenging and unique side hobby to birding – a Tyrant Flycatcher Life List + it would take you all across the Americas in your quest. I could live with that. The Eastern Phoebe did not stay put for long. All of a sudden it took off. It made a short u-shaped flight, presumably to catch a snack, before returning to the same perch. With the amount of rain we have been getting this summer there is no shortage of mosquitoes so any critter that preys on these pesky critters is in my good book.
I came across a stand of shrubs along the Whitemud Ravine trail that looked like Beaked Hazelnut (Corylus cornuta). It had the typical serrated leaves and the small catkins (the male flowers), but I did not find any female flowers or any nuts so I was a bit on the fence for a positive identification. That was until I found one shrub that had the characteristic bristly husks that look like long beaks (hence the name Beaked Hazelnut). The nuts grow inside these husks. The Beaked Hazelnut is our only nut-bearing native shrub and is an important source of food for, you guessed it, squirrels and chipmunks. Birds, such as woodpeckers and jays, also enjoy a nut as a snack. While the nuts are edible, store-bought hazel nuts typically come from the Common Hazel (Corylus avellana) which grows in Europe, around the Mediterranean Sea and throughout Western Asia. For a minute I was tempted to try the nut but decided to stick to the adage of only taking pictures and only leaving footprints and decided to leave the nut for the denizens of the forest.
Another milestone! Post 122 out of 366 makes it one third of the way through my Project 366. Four months in and I think I can safely say that have the ropes figure out by now and that I am on the proverbial roll.
I went for a nature walk this morning to the Whitemud Creek. To mix things up a bit I accessed the trail system from a secluded and well-hidden trail head in the Ogilvie Ridge neighbourhood. This trail head takes you right into a portion of the Whitemud Ravine south of Snow Valley. According to the map it is about a 4 km walk to Snow Valley but I did not go that far today. It started out cloudy and breezy but the sun snuck out behind the clouds about one hour into the walk. The highlight of the walk was the “discovery” of a a pair of ponds off the trail that were busy with all manners of bird life such as Bohemian Waxwings, Eastern Pheoebes, House Finches, and a Downy Woodpecker (no waterfowl though). There was also evidence of recent beaver activity. These ponds do not appear on any map or even in Google Earth. I am sure the ponds are know to the locals, but they are not visible from the main trail and one has to meander through a brushy meadow to find them. As I was finding my way across the meadow I encountered stands of Fireweed (Epilobium angustifolium) a tall perennial herbaceous plant related to willows. The Fireweed is native throughout the temperate Northern Hemisphere, including throughout the boreal forests of Canada. It is a pioneer species and is often one of the first colonizer after forest fires, hence the name Fireweed. It was known as bombweed during the Second World War as it was rapid to colonize bomb craters. Fireweed is one of the best known medicinal plants and has been used worldwide in traditional medicine. Experimental and clinical studies have confirmed that all parts of the plant have a broad range of pharmacological and therapeutic properties, including antioxidant, anti-proliferative, anti-inflammatory, antibacterial, and anti-aging properties. A recent review of the therapeutic potential of Fireweed provides an impressive list of benefits:
Traditional use of fireweed includes an infusion or tea, which has been reported as a treatment for migraine headaches, insomnia, anemia, delirium tremens, infections, and colds. E. angustifolium extracts have been reported to be effective treatments for gastric ulcer; duodenal ulcer; gastritis; colitis; various gastrointestinal disorders, such as dysentery and diarrhea; and prostate or urinary problems, such as urethral inflammation, micturition disorders, prostatic adenoma, and benign prostatic hyperplasia (BPH). E. angustifolium has also been used topically as a cleansing, soothing, antiseptic, and healing agent to treat minor burns, skin rashes, ulcers, and infections, and for treatment of inflammation of the ear, nose, and throat…
Although I am not suffering from any of the listed ailments at the present time, it am tempted to head back and collect some of the leaves while they are available to keep a stash of this miracle plant at home for future uses.
Another pretty flower with an insidious secret. We came across the Creeping Thistle the other day just off the Whitemud Creek as we were on a nature bike ride. Just like other recent pretty flowers we have come across (for example, Cow Vetch, Red Clover and Meadow Buttercup) the Creeping Thistle is an invasive weed that was introduced from Europe and Asia. To add insult to the injury it is often referred to as Canada Thistle, which is of course misleading since it is not of Canadian origin. As far as I can tell, it was introduced in North America accidentally, most likely as a contaminant in crop seeds. There used to be a Thistle Patrol here in Edmonton that went around to natural areas pulling out creeping thistles. Although there are effective herbicides that kill the plant they also kill the native plant, so the incentive behind the Thistle Patrol was to remove this invasive weed manually to avoid the need for spraying herbicides. I have not been able to find any information about the Thistle Patrols activities these days (most recently they seemed to be active in 2013), perhaps the patrol has retired. Did they “win” the battle against the Creeping Thistle or was it too big of a job to keep up with? Who knows?
Right by the parking lot at the south side of Elk Island National Park there was an energetic Yellow-bellied Sapsucker hard at work trying to drill holes in the posts of a widening fence. Sapsuckers are known for creating symmetrical rows with large number of shallow holes on trees in order to harvest tree sap. I wonder if it was working on the wooden fence by mistake (which clearly will not have many sap) or if it was looking for insects (which the fence posts may have). Sapsuckers can make a large number of holes in a single tree and there are known instances where trees are girdled by overly enterprising sapsuckers. The Yellow-bellied Sapsuckers is our only woodpeckers that migrate south in the winter.
South of the 23 Avenue, as it crosses the Whitemud Ravine, the Whitemud Creek splits into two, the Whitemud and the Blackmud Creeks. Right along the confluence of the two creeks there is a large meadow covered in tall grass and purple Cow Vetch. Last time I was there it was a hot sunny afternoon and the meadow was buzzing with grasshoppers. With every step, hundreds of grasshoppers were flushed out of the tall grass around my legs, jumping in all directions simultaneously. As I was making my way through the tall grass the possibility of ticks making a meal out of me did cross my mind. I have yet to find a tick in Alberta and I certainly hope it stays that way. The last time I had an intimate encounter with this bloodsucking parasite was about 30 years ago in central Sweden, when, after a day of portaging a canoe, to my horror I discovered a tick in the warm moist nether regions. By the dim light of a flashlight we ended up having to carve out the beast at night in our tent. Ever since that incident I have a healthy aversion to these critters. To play it safer, I decided to stay on the trails that meander through the meadow, rather than walking in the tall grass. I could hear lots of song birds, but this late in the afternoon most of the were skulking among the leaves and were difficult to spot.
