Visiting a few hotspots in Chatham-Kent

 In between black lighting for moths, I do get out to a few of my regular haunts during the daylight hours. The Keith McLean Conservation Lands, across the road from where Marie and I lived for several years when Keith was still farming, is definitely a worthwhile place to check out especially with the high water that affords great habitat for waterbirds. As shorebirds are steadily heading back south from their arctic breeding grounds these days, there is often a good diversity of them.

Aside from the abundant Killdeer, there are a few of their smaller relatives showing up in small numbers, as in this Semipalmated Plover.

Least Sandpiper is present in small numbers.
Solitary Sandpipers are usually, solitary, although on occasion more than one of this species can be seen.
Lesser Yellowlegs are typically far more abundant than their larger relative, the Greater Yellowlegs, shown next.
Wilson's Snipe may be present, but more often than not, just one or two.
Short-billed Dowitchers are currently around in small numbers, with usually 1-4 seen on an average day. It won't be long before Long-Billed Dowitchers show up, I expect.
A shorebird that is usually found along the shoreline of larger lakes is the Sanderling, shown next. I was a little surprised to see it here on the mudflats. It is possible that the brisk east wind made even less shoreline available along Lake Erie than usual, so it stopped by here instead.
The usual herons and egrets are around, such as these two Great Egrets. Will something more unusual such as a Snowy Egret or Little Blue Heron show up soon? It is time!

I was at Rondeau to do some monitoring of an endangered orchid after one of my stops at KMCL, but those details will have to wait for a future post. However I did manage to stop for a short while at a couple of interesting spots in the park.

The southeast beach dunes are an uncommon and significant habitat in Ontario. Right now there is an abundance of the Cylindrical Blazing-star in flower.

Much rarer, but still the same species, is this white colour form of the blazing-star shown above.

The Marsh Trail has always been one of my favourite parts of Rondeau, but unfortunately due to the high water levels, access is very limited. I did venture a short way down the currently closed trail to see what I could find.

A trio of Eastern Tiger Swallowtails were 'puddling' along the wet sandy edge of the trail.

Arrowhead is a common wetland plant.
The non-native and invasive Purple Loosestrife is, unfortunately, fairly common as well.
Swamp Milkweed is widely scattered, and provide a good source of nectar as well as a breeding source plant, for the endangered Monarch butterfly.
This is Swamp Loosestrife, common where there is a bit of standing water.
A plant that can be abundant, but is an annual and depends on declining water levels later in the season, is Wild Rice. It is considered a rare species in Ontario.
On the subject of rarity, this Blanding's Turtle fits. It was in shallow water at the edge of a pond and when I appeared it ducked its head under water, so all I got a photo of was its back.
A wetland prairie grass is this next one, called Prairie Cord Grass. It is not common at Rondeau.
Swamp Rose Mallow is widely scattered in the Rondeau Bay wetlands, and its large pink flowers are very showy. It is a Species At Risk in Ontario, as it is primarily restricted to the larger wetlands of Essex, Chatham-Kent and Lambton.

Another pink flower occurring in wetland edges, although much smaller than the Swamp Rose Mallow, is this Hairy Willow-herb.

 On the way back, I met these two Viceroys.


I stopped briefly at Sinclair's Bush on the way back, as I wanted to check out the possibilities for black lighting for moths. I had not done any black lighting here yet, but was able to do some a few days ago. That will have to wait for a future post. But I did see a fruit on one of the Pawpaw, a large shrub/small tree that is known from this site. This cluster has lots of flowers in May, but seldom do I see any fruit. This one, and the only one I saw, was fairly high up, so a telephoto lens was necessary.

Another time I went out in the evening to St. Clair National Wildlife Area. On the way there, I came across several groups of from 2-21 Sandhill Cranes way out in some recently harvested grain fields. This next photo was greatly cropped.

I was going to go out to the observation tower, to watch and listen. The wind was fairly calm. Along the way I noted quite a bit of Missouri Ironweed, a tallgrass prairie wildflower that is appropriate for the site considering that much of the immediate area was historically tallgrass prairie or wetland, depending on the water levels of adjacent Lake St. Clair.
There were lots of swallows freewheeling over the marsh in their quest for insects. Occasionally one, such as this Tree Swallow, would take a rest on a Phragmites stem.
A couple of small groups of Sandhill Cranes flew by.
A Great Blue Heron was settling in to its night time roost.
As the sun set, since there were no clouds in that part of the sky, the sky turned a brilliant hue of orange and yellow close by the sun itself.
The telephoto lens I had enabled me to hone in on the most colourful part of the sky.
A short while after the sun went below the horizon, the brilliant colours began to fade.....
.....but not before a few little clouds on the other side of the sky were able to reflect a bit of pinkish colour.

It was a great evening, and hardly a mosquito at all.

Celebrating Wetlands!

Most of you will already know that a few days ago, Feb 2, was Groundhog day, but did you also know that it was World Wetlands Day? Wetlands are some of the most misunderstood and abused natural habitats on earth. They provide and cleanse sources of fresh water that we all need. They prevent flooding, and who hasn't heard of the major floods occurring in so many areas. Yet wetlands are drained, filled in, and treated like a garbage dump etc.

Some of the most extensive wetlands on earth occur right here in Canada including major ones in Ontario. The Hudson Bay Lowlands stretch inland from Hudson Bay for several hundred kilometres, and extend from the Quebec border to the Manitoba border and beyond. I had the privilege of being up there doing wildlife surveys for two weeks in both 1990 and 1991. It is one thing to look at this area on a map, but quite another to spend several hours flying over it to get to one's destination, and realize how little of the area you have actually seen. Being on such a landscape and far removed from any semblance of civilization is an awesome experience.

 It was incredible, to say the least, with many dozens of species of wildlife nesting and migrating, including some that rarely show up in southern Ontario such as Pacific Loon and Parasitic Jaeger.

While those wetlands are still relatively intact, there are constant threats to their survival and integrity. Resource development, especially mining, is constantly being explored. In addition the wetlands are being impacted by air borne contaminants that originated in the developed part of the world.

Farther south, the boreal forest of the Canadian Shield is dotted with wetlands.But even those, if they are close to an urban area, can be tainted. This next photo is in the vicinity of North Bay. At the far right of the photo you can see buildings. It is a commercial area, and there are things falling into the wetland. In another wetland nearby there is a auto wrecker/recycling depot immediately adjacent, and some of the material has fallen into the water.

 Beavers seem to get along reasonably well, as there are numerous beaver lodges. It doesn't hurt that the beaver pelts are not as valuable as they used to be!

Some of the most diverse wetlands in the entire country are here in southern, and especially southwestern Ontario. Most of the time, the term wetlands conjures up the idea of large areas of cattails, and rightly so. Wetlands along the coastal areas of the Great Lakes are some of the largest and most diverse wetlands.

 They are immensely valuable for fish, invertebrates and plants that cannot survive anywhere else. More visible is some of the bird life. Marsh Wrens are abundant and frequently heard but seldom seen.....
 .....as are Swamp Sparrows.
Much rarer are things like Black Terns, which nest on muskrat houses or exposed and mounded  mud flats.
 Least Bitterns are present in some of the larger and best quality wetlands, but are not plentiful and more often heard than seen.
 Common Gallinules are much more often heard than seen as well, as they give various squawks and hoots from the density of the vegetation.
 Once in awhile, a patient observer might get to see a family of them roaming from one patch of vegetation to another.
Various turtle species are abundant here.

 Within the stand of cattails, sometimes some rare plants can be found. This pink flower emerging from the cattails is Swamp Rose Mallow.


 And depending on water levels at certain times of the year, Wild Rice can be found.

 In good years, this annual plant can be fairly abundant.
 The next photo shows an almost solid stand of Wild Rice.
 Wild Rice isn't in the foreground, but is a solid stand in the back ground here.
 And in open water, there are floating plants of various water lily types. These plants with their floating leaves provide shade and coolness for the critters living below, and also a surface for things to attach themselves to.
 However all is not well with these wetlands. The non-native and very aggressive Common Reed, also known as Phragmites, can quickly take over a wetland becoming an almost solid stand. Wildlife generally does not adapt well to such an aggressive invader.

 Wetlands can be wooded, and these are appropriately known as 'swamps'. They are usually much smaller than the coastal wetlands, and once the trees are removed, can be easily drained and converted to agricultural crops. Unfortunately when that happens, it directly increases the risk of flooding nearby, since the sponge-like absorption of these wooded wetlands is no longer functional. Please keep that in mind next time the waters of a creek or river near you is in flood stage, an event that is becoming more and more frequent.


 Wetlands are clearly a valuable component of our natural environment to celebrate, enjoy and protect. Next time you drive by one or visit one, I hope you take a few moments to appreciate all they mean to our landscape and to us!
