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.

Young female Wood Ducks
 

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.

Rondeau Butterfly Count

Just a brief note regarding Life on a Sandspit: it seems to have garnered a lot of interest and is doing well.

It is currently available at the Friends of Rondeau store (inside the Rondeau Visitor Centre), as well as the Bayview Market, just outside the Rondeau PP gates. It is also available via the Sydenham Field Naturalists, and you can see it, along with other nature publications on their web site here. I am slowly finding other local sites where it may be available, and will provide updates on those as they occur.

On to the butterfly count post.

Just a few days ago, on July 9, was the annual butterfly count, for the Rondeau area. Over the past 22 years, it has ranged from 35 to 47 species, averaging about 41 species. I don't have the final tally for this year, but based on the area that I and my colleagues did for this one, I think we will definitely be below average both for total species and individuals. I usually get about 18 species, but this year I got only 15. Of course weather is always a factor, and the cool, cloudy, misty weather this year did not bode well. And a downpour of heavy precipitation in the afternoon for some, did not help at all. Nonetheless, it can always be worthwhile to get out and see what is around. The following photos are ones I took while meandering through the several spots I normally cover. I didn't get photos of all the species I recorded, and the results vary.

This first one is the only swallowtail species I encountered, and just one individual!

Black Swallowtail
Bronze Coppers, next, are not a guarantee, and I only saw this one. Fortunately it cooperated to get the kind of photos that allowed me to separate it from the American Copper.

If this count was taken a few years ago, I would have no problem identifying this next one as a Summer Azure. However the lepidopterist taxonomists have examined the Celastrina genus a little differently, and it apparently is not quite so easy, so this one could be as Summer Azure, but I left it as Celastrina sp.

Common Wood-nymph

Eastern Comma

Eastern-tailed Blue

Little Wood-satyr
Monarchs, shown next, got off to a slow start in the count, but as the day wore on, I came across several areas where Common Milkweed was present in the hundreds of plants. One area could have even had more than a thousand plants, so getting several dozen Monarchs was not hard. If I had been able to carefully survey this largest milkweed site, I could have easily doubled the number of Monarchs, but by that time I was losing energy so I did most of my surveying via scanning the large field with binoculars.
Crescent butterflies are normally fairly common, but for some reason, that wasn't the case on this day. I had just this one Northern Crescent.
Although the ? on this next butterfly isn't all that visible, it was indeed a Question Mark.
Red Admirals, at 57 individuals, were by far the most common of the butterflies, other than Cabbage Whites at about 70.

Of course anytime one is out in such habitat, there are always other things to see, so I took advantage of the photo ops I was given. This Eastern Gartersnake was quietly sitting along the edge of one of the first trails I took. I presume it was trying to soak up some of the non-existent sunshine, as it never moved even a bit, although I got quite close.


Along the Erieau Marsh Trail there were the usual things like Great Blue Heron.....
...and even a Trumpeter Swan.
Song Sparrows were common in most areas.....
...as were Red-winged Blackbirds.
Along one area, which follows an old Railway Track, I saw three Wild Turkeys, but true to their character, did not allow me to get very close. This next photo is highly cropped.
Along this same part of the area I covered, I noted several clusters of a Species At Risk, known as Prairie Rose.
And I even saw the occasional day-flying moth that enabled me to shoot it: the Eight-spotted Forester.

Once all the results are tabulated, I will update the results for this count, but as far as I can tell in talking with several other counters, it will not be one of the better ones. Every year is different! Update: there was a total of 1777 individuals of 36 species recorded on this day, so definitely on the low end of average.
