St. Clair National Wildlife Area, one of the highlights of southwestern Ontario

 St. Clair National Wildlife Area (SCNWA) has always been a favourite place of mine to go. It is special in its own right due to the high quality wetlands, and even better it is quite close to home and so accessible!

Many of my previous posts include some of the things I find there along with things from other sites, but this one will focus only on this NWA. Being ~600 acres (~240 ha) in size provides lots of opportunities for wildlife, especially wetland birds. A further benefit is that there are other wetlands immediately north and southwest of it, to improve the overall wetland features for wildlife. 

The hiking trail that crosses the heart of the wetland is invaluable to appreciate what it has to offer. The presence of an observation tower enhances a visit. These first two photos were taken from the tower, and the first one shows the hiking trail leading to the tower.

The second photo gives an idea of the expanse of the marsh, with some open areas scattered throughout, making it ideal for many water birds.
One never knows what to expect, so being constantly on alert for anything flying by is essential. One of the highlights of a recent evening visit was to observe both an adult Bald Eagle and an Osprey, with the eagle harassing the Osprey. I watched them for several minutes, as at one point they were flying almost right overhead. The down side was that it was getting close to 8 p.m. so the light wasn't great and they were against a bland sky, but I rattled off a bunch of shots. Here are some of the more satisfying ones. It was hard to tell, but it appeared that the Osprey had something in its talons, and the eagle was trying to get it to let it go so it could pounce on whatever it had. I didn't see any success of this, and eventually the two birds separated and moved off.

 

 


On another occasion when I was out in the evening, I enjoyed an attractive sunset.


Sometimes one can see things like Sandhill Cranes passing by against the colourful sky.

Sunrise photography is also quite fun and rewarding. These next two were not taken recently, but a few years ago when I had a special interest in capturing sunrise shots from various points in Chatham-Kent.



 Aside from the landscape, er, waterscape photography, the main purpose for many visitors is to see the wonderful diversity of flora and fauna. Here are a few things from mostly recent visits, starting with butterflies.

Black Swallowtail

Clouded Sulphur 
The first two butterflies are to be expected. This next one is a Common Buckeye, and it is anything but common. This was the first one I had seen this season. A bit of a surprise was to see three of them, and they were vying for a spot to land. This one was the successful one, and I saw the same one (based on the wear and tear on the left forewing) in the same place two days later.

Monarchs, of course, were fairly abundant which wasn't surprising due to the plentiful milkweed on which to lay eggs when they weren't feeding on Missouri Ironweed.

Red Admiral

Viceroy
The flowers are more abundant in the later part the season, with lots of goldenrod and sunflower species lining the trail these days. One of the highlight species to see is this next one, the Marsh Tickseed, which is an endangered species, but fairly common along at the waters edge along both sides of the trail.


Another rarity, although not as rare as the previous one, is Missouri Ironweed.

 

Another rarity is Field Thistle, next.


 Not a rarity at all, and actually fairly common, is Evening Primrose.

 

Of course there are quite a few Leopard Frogs hopping along the trail.

 But birds are one of the main reasons people are visiting, and for good reason. The views and diversity are great, with some giving good photo opportunities, and others just views through binoculars as they scoot through the skies. Waterfowl are building in numbers, and once the hunting season starts, they will be increasingly abundant at the NWA as it is a safe haven for them. Here are a few waterbirds that I have recently encountered and photographed.

Great Blue Heron
Less frequently the herons will be up in a tree along the edge.


Great Egret
One of the highlights of a few years ago, when the water in the NWA was lower, was to photograph a large group of Great Egrets at their overnight roost. This photo was taken in late September just before sunrise. I had to use a very slow shutter speed, due to the very early morning light, but the birds remained motionless.

Waterfowl, especially Mallards will be quite abundant in the next few weeks.

Mallard
Okay, not a waterbird in one sense, but Northern Harriers frequently nest in wetlands, and are often hunting for something to feed on.


The first two photos were taken from the tower. And then the bird landed a short ways just off the trail, and allowed me to get this next photo.
Pied-billed Grebes are more often heard than seen.
Sandhill Cranes are often in the area, and will nest in or adjacent to the wetland. When feeding in the shallow water, they can sometimes be almost obscured by the tall wetland vegetation. This was taken from the tower.
 Wood Ducks are a favourite, and are one of the more common duck species present at the moment.

So many photo opportunities to enjoy at this nationally significant natural area. Enjoy it when you can!

UPDATE: I have been informed that as of Oct 1, 2025, public access to the SCNWA is not available, as there is some upgrading to the trail system/bridge getting underway. Public access is restricted until Jan 1, 2026.

A new to me endangered species, among other photographic findings

 On one of my recent excursions to St. Clair NWA, I came across a plant that was not abundant, but scattered here and there along the cross-dyke trail. After photographing it and searching its identity, I came to discover that it is Marsh Tickseed (Bidens trichosperma). I had never seen it, or at least never noticed it before. It is considered Imperiled in Ontario and Canada.

While at first glance, it could easily just be passed off as a sunflower type, which it is, the key characteristic to note is the large, but finely divided leaves, unlike any other sunflower type that I am aware of.

Of course any visit to SCNWA will turn up other things to aim the camera at, including:

Northern Harrier

While some of the Sandhill Cranes will be out feeding or resting outside the NWA, sometimes mixed in with geese, they often fly into the NWA for over night, so being ready for them in the evening can be successful.

In checking the range and locations for the Marsh Tickseed, I found out that there are a couple of records for Rondeau. I had never seen it there before. Since this was prime time for it to be in flower, and most visible, I decided to check out similar habitat along the Marsh Trail at Rondeau.

While I was not successful in finding it there, yet, I have another location in the park to examine. But over the course of my 10 km hike, I did come across other things that I aimed the camera at.

Straw-coloured Flat Sedge
This next one, Swamp Thistle, looks a lot like one of the other thistles in this group, but its particular colour of purplish as well as the general shape of the flower head and the supporting flower structure is distinctive.

I only had my camera with the 100 mm macro lens so as to be able to photograph plants. Had I taken my other camera with the big telephoto lens, I could have gotten some great shots of a pair of adult Bald Eagles soaring not all that high up against a blue sky (much closer than this next photo, which was taken awhile ago)....

....and a close-up of a Sandhill Crane that flushed out of the marsh not far away (again, this is one from awhile ago). But since I knew I was going to be out for a long walk, I didn't want to burden myself with the second, larger camera gear.

On another occasion, while searching for plants in the interdunal meadows of the southeast beach of the park, I came across a few things such as:

Bristly Sedge

Common Buckeye caterpillar
An adult Common Buckeye was busily flitting around close by, sometimes hunkered down amongst the grasses.

Little Green Sedge
This next pink beauty is a Small-flowered False Foxglove, which was quite abundant in the lower damp areas. It was on this species that the Common Buckeye caterpillar was feeding on.
Along a drier trail I found these white forms of Great Blue Lobelia, usually a deep blue colour.

Along the Erieau Marsh Trail, I came across:


Least Sandpiper
..and some skulking Wood Ducks.

A visit to the Mitchell's Bay North Shore Trail enabled me to get much more open photos of Wood Duck....

...as well as another Common Buckeye...

...a Differential Grasshopper (sometimes hard to figure out where the common name comes from...)...
...this Great Blue Heron...
...and of course one or more of the typical half a dozen Great Egrets that are often found and quite photogenic. This one had just grabbed a fish, which is still showing at the side of it beak.

Last but not least, I made a brief stop at the Keith McLean Conservation Lands, and while photo ops were not plentiful on the visit here this particular time, I did manage to capture one of this Ruby-throated Hummingbird perched at the top of this dogwood shrub.
