Odds and Sods

Haven't had a tonne of material to post of late but I thought I'd share some interesting photos from the last couple of weeks.

The photo below is an amazing American Beech (Fagus grandifolia) growing in a woodlot near the Greenock Swamp between Walkerton and Kincardine.  It's by no means the largest Beech I've encountered, but look at that crown! Full points for good (albeit not typical?) form. 

Last weekend I was visiting my parents in Thorndale.  Checking out a planted Tulip Tree (Liriodendron tulipifera) in the yard dangling structures caught my eye.  I'm just starting to get more into moth identification and the best I can come up with is that these cocoons belong to either Promethea Silkmoth (Callosamia promethea) or Tulip Tree Silkmoth (C. angulifera).  The larvae of each species will apparently forage on Tulip Tree so no leads there per se.  There were a total of 8 cocoons on a tree that's only about 7-8m in height.  I'll have to check back in on these.  The moth book I recently purchased is the Peterson Field Guide to Moths of Northeastern North America by David Beadle and Seabrooke Leckie.  So far looks to be a very comprehensive resource.

An ambitious mission to Parkhill Conservation Area to search for the uncommon Harbinger-of-spring (Erigenia bulbosa) (a forb in the carrot family) didn't yield results (I was going on the very slight chance I could find a population I know of, perhaps poking through the leaves).  A very nice spot nonetheless with some interesting shrubs like Leatherwood (Dirca palustris), calling Spring Peepers, and 80 cents in beer can revenue!

Botany at 35,000 feet

A few months ago I was out for a hike along the Thames River near Thorndale.  Venturing through a rather boring expanse of Reed Canary Grass and Manitoba Maple, I got to the edge of the river and spotted a patch of Lizard's Tail (Saururus cernuus).  The common name for this plant is in reference to the long, showy white flowers which taper and look like a bushy tail...I'm not sure why lizard...it was probably a coin flip between Lizard's Tail or Unicorn's Tail.

This species inhabits river and pond edges, muddy shores and sometimes swamps.  It has a distribution in Ontario which roughly aligns with what is considered to be the northern extent of the Carolinian Zone.  It is considered vulnerable in Ontario but as the rest of my post indicates, it can be quite common on certain lengths of a watercourse, such as the Thames.

Here is a small stand along the Grand River in Cambridge.





What is interesting is that in fall, when the leaves and stems die back for the winter, they dry a deep reddish-brown hue in colour.  This reddish-brown, when viewed from Google Earth creates a very distinct colour signature.  The photo below shows the stark contrast between red and the greenish colour of what is predominantly Reed Canary Grass.

Having encountered one of these patches while out for a hike, then extrapolating that reddish brown colour up the river for a few kilometres, it quickly becomes apparent that the Thames River between Thorndale and St. Marys is packed with Lizard's Tail.
People joke about botany at 70km/hr while scanning roadsides for interesting plants, but this desktop botany, or botany at 35,000 feet is a whole other level of fun!

Niagara Birding

Nathan and I were in Niagara Region the past couple days and got to do a bit of Niagara River birding in the down time.  Working on my gull ID Nathan pointed out Iceland, Thayer's, Glaucous and a Little Gull today.  We were chasing the Slaty-backed Gull...with inconclusive results (see Nathan's blog post).

While at Dufferin Islands Natural Area we did spot this female Pine Warbler.  Checking out the ebird sightings for January 2017 she (and he) seem content to hang around!

Snow Geese, and lots of 'em.

I was in Eastern Ontario for work last week and had the pleasure of pausing throughout the day to watch flocks of (noisy) Snow Geese flying over.  My high count for a given flyover of a bunch of loosely-formed flocks was 3000 geese!  Here's a shot and a video I took.

A Week in SE Alberta

I got back last night from a week in southeast Alberta.  Alyssa is working on contract in Medicine Hat and while late November isn't prime for wildlife viewing in that part of the continent, we had a fun time exploring a few local natural areas.

Home, home on the range, where the Rocky Mountain Mule Deer (Odocoileus hemionus hemionus)...

...and the Pronghorn Antelope (Antilocapra americana) play.  The deer became a regular site pretty quick.  The pronghorn were an unexpected treat just outside of Cypress Hills.

Coyotes are somewhat common and scanning the open rolling terrain yielded a half dozen or so sightings throughout the 2 days at Cypress Hills.

Rose hips
Lupine getting an ambitious start on 2017.
 

Lodgepole Pine (Pinus contorta) is one of the dominant conifers.
If you dig hard you can find goodies like Prairie Smoke (Geum triflorum)!
American Three-toed Woodpecker (Picoides dorsalis), score!
...and it's preferred habitat 'round these parts.
 Bearberry (Arctostaphylos uva-ursi) is a common groundcover plant among the conifer stands.


The next two photos give an appreciation of how Cypress Hills became an island untouched by glaciation which created the stark contrast with the bare shortgrass prairie that extends for thousands of miles around at lower elevations. 

The Sweetgrass Hills of Montana are visible in the distance.  I didn't venture too far off the trail here as a truck with an Elk hunting permit was parked at the cul-de-sac.  Apparently this location is the highest elevation in Canada between the Rockies and Newfoundland.

We took a (more) scenic route back to Medicine Hat via Eagle Butte on the west side of the park.  I was curious about checking out historic Margaret's Church so we stopped in.  The "Beware of Dog" sign gave way to a pooch that would lick your face to death.  The stained glass in the church was well-tied to the surroundings showcasing Meadowlark and Sunflower among other flora and fauna.



Spending a day in Medicine Hat I decided to check out Police Point; a City park with an extensive trail system but comprising a large swath of grassland and Cottonwood floodplain.
 
A favourite grass, Blue Grama (Bouteloua gracilis)
A not-so-favourite grass, the agressive invasive Crested Wheatgrass (Agropyron cristatum).  This species along with Smooth Brome (Bromus inermis) are widespread invaders of native grassland in the area and where introduced as forage for livestock.  Once they take hold they suppress and out-compete prairie vegetation.

Wild Licorice (Glycyrrhiza lepidota)
 I believe this downy-leaved milkweed is Showy Milkweed (Asclepias speciosa).

Sand Reedgrass (Calamovilfa longifolia)
The stout, woody shrub Silver Sagebrush (Artemesia cana) is widespread and abundant.  The only Prairie Rattlesnake I've ever seen was tucked under the shelter of one of these in Grasslands National Park in Saskatchewan.



The following morning I drive south to Red Rock Coulee.  The spherical reddish sandstone concretions give the site it's name with a couple hundred of these strange features emerging from the eroding bearpaw shale within which they sit.  A couple of locals told me the place was rife with rattlesnakes in the summer and they were surprised when I said I'd have to come back in season!
 
Colourful lichens on the concretions.
A few botanical finds could be had including patches of the showy prairie wildflower Great Blanketflower (Gaillardia aristata) in the bottom right of this photo.

The rocky peak had a nice patch of Starvation Prickly-pear (Opuntia polycantha), other cactus species occur in Alberta but this is the species of Opuntia common to this area.


On our way to Calgary for the weekend we stopped by the Royal Tyrrell Museum in Drumheller.  I had never been and it was a fun way to spend the afternoon after a 2.5 hour drive up from Medicine Hat.  A few shots below...




This Tyrannosaurus rex is nicknamed 'Black Beauty' for the dark tone of the bones which was a result of manganese in the water during fossilization.  It's in the classic 'death pose' with the head and legs pulled back.
 
Gumweed (Grindellia squarrosa) hanging on to the last few petals.
 The landscape in and around Drumheller is quite something to see.  The stratified sediments of varying colours of brown, beige and red comprising an extensive network of mostly bare, eroding hills that flank the Red Deer River.

Get to the Point

Back in September I headed down to the Fort Erie area, specifically Point Abino.  Alongside summer vacation homes, Point Abino is home to an interesting mix of habitats including dunes, coastal meadow marsh, bedrock pavements along the shoreline and nice areas of forest.

If you spend much time in meadow marsh habitat you get familiar with a diversity of sedges and rushes.  The one below is Common Three-square (Schoenoplectus pungens).  This stand was in an area which a local told us had once been a vast expanse of meadow marsh prior to development and boat traffic.  Wild Rice (Zizania spp.) was once rather abundant here.

Clammyweed (Polanisia dodecandra) is sticky to the touch as the name suggests.  I found the smell of the oily substance to have the odour of diesel fuel.  This species is largely found in beach habitats but can also occur inland on gravelly bluffs and other similar habitats.

Another beach species, Sandbur (Cenchrus longispinus) is one you definitely know when it's stuck in your socks!

A Bugseed (Corispermum spp.), of which Niagara has a few.
Winged Pigweed (Cycloloma atriplicifolium) was a new one for me.  The small saucer-like flowers cover much of the plant.

The rain pounded and the wind howled...all...day...long.

The point is home to Niagara Region's only population of Sand Cherry (Prunus pumila).

An iconic (and uncommon) wildflower of Lake Erie coastal marsh habitats, Swamp Rose-Mallow (Hibiscus moscheutos).  When in flower the large, pink hibiscus flowers are hard to miss.

The uncommon Pringle's Aster (Symphyotrichum pilosum var. pringlei).
I rarely pass up a photo of Kalm's Lobelia (Lobelia kalmii).  Patches of the light purple flowers were in bloom here and there along the lakeside bedrock pavements.

How about that.  The one and only extant population of Kalm's St. John's-wort (Hypericum kalmianum) in all of Niagara Region.  That's it, everything in the frame of this photo.

Buttonbush (Cephalanthus occidentalis) fruits had turned a deep red.
