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.

Backyard Wildlife

 Over the years we have developed a fairly varied back yard, with lots of space devoted to a veggie garden as well as mixed plantings of native species. I tend to lean towards the tallgrass prairie species, but there are other things, along with various tree species. In the last few years, we have been busily involved with a community garden of 12 plots, in the park behind our place and just a 15 second walk from our yard. Two of those plots have been specifically planted with native plants to support pollinators, and the pollinators have found it.

Given the situation with COVID and the practice of staying home as much as possible, these 'naturalized' areas have provided lots of photo opportunities. It also helps that since I don't do well in the heat and humidity of this part of Ontario, staying at home and going out for brief forays into these vegetation patches works well.

Sitting out in the back with a morning coffee can be enjoyable, waiting to see what butterflies flutter by. I'm not always prepared with the correct camera and lens combination, but here are a few of what I have captured.

Giant Swallowtail

Eastern Tiger Swallowtail

Mourning Cloak

Red Admiral

Peck's Skipper

Monarchs have been quite regular, with sometimes several flitting about at one time as they check out the numerous milkweed plants scattered about. And there is the inevitable egg laid underneath the leaf. They are very small, but visible upon close examination.

Eventually they will hatch, at least that is the hope. Considering how many adults we've seen in and around the yard, the number of caterpillars is surprisingly low. This next photo shows a very young Monarch cat, judging by the size of it compared to the size of the milkweed floret it is resting on.
The next photo is more or less what most of us are more familiar with. I suspect it went off to pupate a day or so after I took this photo.
Black Swallowtail butterflies are far less common than the Monarchs and we have only seen about three caterpillars so far. They prefer dill or parsley so those are the plants to check.

Related to the butterflies are moths. Regular readers will not be surprised that I put a plug in for moths, since I have been spending more time than ever with my black light trying to lure and photograph the myriad moths that exist. But there are day flying moths as well, and as more and more research goes on, it is evident that moths are great pollinators. Their furry abdomen easily catches pollen from one flower and transfers it to another.

Chickweed Geometer

Eight-spotted Forester

This next one is the Nessus Sphinx. There are a lot of different kinds of sphinx moths, and many of them can be seen visiting flowers in the early morning or late evening. Sometimes they appear to be at first glance, a small hummingbird, as they hover by a flower much like a hummingbird and extend their long probocis into a flower in search of nectar as this one is doing.

This next moth is quite common. It is known as either the White-speck or the Armyworm Moth. I prefer the former name.

Garden Webworm
This next one is the caterpillar of one of the numerous Geometer types of moth, and is exploring the head of a Black-eyed Susan.
An attractive moth, but not one that most gardeners like to see, is the Squash Vine Borer, shown next. It is feeding at a Common Milkweed.

 Not directly related but just as scorned, is this next one: the Squash Bug.

 While Common Milkweeds are favourite plants for many species of moths, butterflies, beetles and other invertebrates to feed or hang out on, they can also be deadly to some. The individual flowers are intricately designed, as this close-up of a couple of flowers show.

But those nooks and crannies of the flowers can be traps, as this honeybee has discovered. If an insect is small and light enough they can crawl through the flowers without any trouble. If they are large enough and strong enough, they can likely extricate a foot or leg that momentarily gets trapped. But if the insect is neither, it may be just heavy enough to get caught, but not strong enough to escape. Hence one of the most commonly trapped dead critters I have found on milkweeds is the honeybee which is not native to North America and is not as well adapted to forage on some of North American plant species.
The Large Milkweed Bug, next, can be quite abundant......
.....as can the Red Milkweed Beetle.
There are often other beetles roaming around flowering plants in the garden such as these Banded Longhorn Beetles.
Wasp types are often plentiful, such as this Great Golden Digger Wasp, on some Thyme.....
...and the Great Black Wasp. This one is busy on a Mountain-mint flower, and it is common to see a dozen or more frantically searching for food.
An even larger and more robust wasp type is this Cicada Killer.
Much smaller, and more timid, is this type of Treehopper.
This next one is a Pennsylvania Ambush Bug. It isn't all that common, as I typically only see two or three a year.
Another wasp is this type of Paper Wasp, at this point busily cleaning its hind legs.
There are many mimics in the insect world. This looks like a type of wasp, but is actually a Large Headed Fly.

Compost Fly
I always enjoy seeing a few of this next species, the Feather-legged Fly. It is colourful with its black wings and reddish orange body.
From this angle, the feathery scales on its hind leg are more visible.
These next two are members of the Green Bottle Flies group.

With so many small flying insects around a garden, it will be no surprise that dragonflies are fairly regularly seen. Blue Dashers seem to be the most common species as of late.

Here, a young Chipping Sparrow is out becoming familiar with the neighbourhood after being hatched from a nest in our White Pine tree.
There is always lots to see, and photograph!
