Plants and bugs of Rondeau, and another threat to some shrubs

 I've been giving my camera equipment, as well as myself, a good workout lately, but being careful not to get too caught up in the heat and humidity. Rondeau gets a lot of my attention, as most readers will know. And this is a wonderful time to find late summer flowering plants, as well as a multitude of different insects that come to visit. Here are some of the highlights, starting with plants. American Ginseng is an endangered plant, and I have been keeping an eye on a few individuals as they progress through the season. This first photo shows a plant with developing seeds. A short time after they turn red, they will fall off.

One that is coming into peak form right now is American Hog-peanut, next, a member of the legume family.
A Carolinian species that likes rich woods is next. It is known by several common names, the main one with which I always thought was appropriate is Richweed (Collinsonia canadensis).

There are quite a few along the Rondeau Road area, in various stages of development.
A colourful, but not native plant is Creeping Bellflower. It is not widespread.

One that I thought was quite late to be in flower, but was in fine condition, is Flowering Spurge. It often is found in open areas, such as prairie or savanna, but this one was along a heavily shaded road edge.
Great Blue Lobelia, next, is fairly widespread and distinctive.


Indian Tobacco

Lopseed

A plant that I am always on the hunt for, although knowing its unpredictability in flowering makes it a challenge even at the best of times, is this little orchid, the Nodding Pogonia. It is an endangered species, with the only known location in Canada being at Rondeau. It is often very difficult to see, as this next photo shows. I photographed this with a 100 mm macro lens at a distance of about 6 inches! It can easily be missed, or worse, stepped on, so its location is not advertised, and even I seldom go out unless I think the weather has triggered its flowering, when it is more noticeable.
It looks a little bit showier when it finally opens, for a day.

Pale-leaved Woodland Sunflower
Another endangered species is next. It is Rough Blazing-star, and generally considered to be a prairie or savanna species. It occurs in a couple of savanna type habitats at the park.

Related to the Creeping Bellflower, shown earlier, is this native one, known as Tall Bellflower.

And a tall flowering plant but with tiny flowers is next: White Vervain.

Wood Nettle
And finally, Woodland Sunflower. It differs from the Pale-leaved Woodland Sunflower, shown previously, in that the base of the leaves are tightly clasping the stem.

And there are various insects to see in a variety of places.

Ailanthus Webworm Moth (not native)

Fall Webworm Moth caterpillar
Next is a member of the Leafcutter Bee group. Specific species is yet to be determined.


Lemon Cuckoo Bumble Bee

Northern Paper Wasp
Next is a Perennial Mason Wasp, an endangered species.

Pitted Mason Wasp

Pure Green Sweat Bee

Spurred Ceratina
On one occasion when I was out exploring I came across this chunky looking caterpillar. It is a Tulip-tree Silk Moth, the first time I had ever seen this caterpillar.
It was partially wrapped up in this dead American Beech leaf when I first discovered it.
 For anyone who has been out roaming the park in recent weeks, you might have noticed a lot of Spicebush shrubs looking very unhealthy. Some just show signs of a problem with a few of the outer leaves....

...while others are completely dead, or at least appearing so.

 The cause is somewhat inconclusive at this point, but there are several things that may be happening. The most likely one is something called Laurel Wilt. Regardless, it is quite widespread at Rondeau, especially towards the north end. Hopefully the cause can be determined, but it is unknown what a solution might be, if any exists. I plan to discuss some of the major forest changes at Rondeau in more detail in a future post.

 Also a reminder is that both my books, Life On A Sandspit, and Natural Treasures of Chatham-Kent, are available at the following locations:

-Friends of Rondeau Bookstore (inside the Rondeau Visitor Centre) 

-Bayview Market, just outside the Rondeau gates

-Mindful Market and Eco Hub, main street, Blenheim

-Mitton's Jewelers, main street, Ridgetown 

-Book Brothers, King St E, Chatham

Hawks on the move, Baird's Sandpiper and a late season orchid

 When I haven't been out with the black light, there are always lots of other things to enjoy. Just a few days ago, Marie called my attention to a large group of birds swirling overhead in the back yard. Given the time of year, I immediately thought of Broad-winged Hawks on the move, so I grabbed my camera and headed out. 

Broad-winged Hawks, indeed. One could see them arising from a woodlot east of home, likely Paxton's Bush or another one even farther east at the edge of town. They weren't in full kettle mode, so they were just lifting off from their overnight accommodations.

This first image just captures a part of a group. I counted 158 birds in this one, but there were many more beyond what I captured. There were  probably 200-250 birds in this single group. Over about a 30 minute period, there were quite a few groups of various sizes, some at least as large as this one, along with numerous smaller groups and even a few singles.

Quite a few flew directly overhead as I stood in the back yard, or just outside the fence to get a less obstructed view.
Of course there was a mix of birds, including adults, shown next....
....and sub-adults, like this one.

Overall, I estimated there were at least 2000 birds that flew over the yard, or within sight of it. It was certainly the largest number of Broad-wings I had seen from the yard in many years. There was an occasional Turkey Vulture and Red-tailed Hawk mixed in with them, and likely others.

Broad-winged Hawks in these numbers are not typical in this immediate area. Usually they make their way to the north shore of Lake Erie, using the thermals of rising air to soar and glide. But the lake doesn't produce these thermals, so they use northwesterly winds to carry them along the lake shore to where they can cross at the narrowest point, which is at the Detroit River, before continuing southwards to their wintering grounds. However when they are on the move and the winds are predominantly easterly, they may travel farther inland, resulting in the occasional soaring over places like our yard, before continuing west and southwest.

Sticking with bird highlights, I have been to Rondeau on occasion, but sometimes more for some exercise and botanizing, although always keeping an eye open for birds. There have been various warblers, but they were most often seen darting across the trails from one dense stand of shrubbery to another, so getting a photo was next to impossible. I did manage to get a quick, back lit shot of a Blackpoll Warbler, which seemed to be the most common species when I was around, so not surprising that it was one I managed to photograph.

There were a few vireos around as well, including this Red-eyed Vireo.

Rose-breasted Grosbeaks were scattered here and there, and occasionally sat on an open branch long enough for a photo.

There are other things to see as well, including this Tall Bellflower, which has normally finished flowering weeks ago....

...and this White Snakeroot, which is in more or less peak flowering condition these days.

Another one that is usually fairly common these days is White Rattlesnake Root.

 

I was in the vicinity of a known population of the endangered Red Mulberry, so grabbed some photos of its characteristic large, pie-plate sized leaves, with long drip tips.

In some of the recently mowed areas, there were a few of these Great Plain's Ladies' Tresses in various stages of flowering. It is not officially rare, but is not common either. It is widely scattered across southern Ontario, and can be fairly abundant if the conditions are right (open sandy grassy areas, that have not been mowed for several weeks).
It has a characteristic strong fragrance, reminding me of a particular type of hot plastic. Another feature is to see the humped shape of the individual flower and the yellowish centre of the down turned lip.

A visit to the Blenheim Sewage Lagoons can be worthwhile, although sometimes it is anything but. However on one of my returns from Rondeau I stopped here and found it worthwhile. There were quite a few gulls hawking over some of the ponds, mostly Ring-billed Gulls. There must have been a large number of insects flying about to get their attention. As expected, both adults and sub-adults were in the mix of a couple of hundred gulls.


I saw this Red-necked Phalarope from quite a distance. The light was better for this photo, but due to the distance it was greatly cropped.
I did manage to get to a closer spot, but the bird was back lit, so even with a bit of extra processing, this is the best I could do.
A dozen of more Northern Shovelers were swimming back and forth with their characteristic 'bill in the water'  style as they swam around, their wide bills scooping or filtering small items to gobble down. Again, most of the time they were back lit.
Some of the local Ruddy Ducks were at a distance, but this one was trying to keep a low profile in a build-up of floating vegetation.
It eventually must have realized that it wasn't as well hidden as it thought, so sat up a little more and swam away.

Lesser Yellowlegs were, as usual, the most abundant shorebird.

But the highlight for me on this visit was to get a fairly cooperative Baird's Sandpiper in view, and I was able to get a few shots. The somewhat brownish colour of this 'peep' along with the longer wingtips that extend beyond the tail, are key features for identification. It is not a common species at any time, but typically show up in ones or twos in the autumn migration. The greenish colour in the water is a result of some kind of chemical that is used for the sewage lagoon water treatment process. I do not know what it is, and I hope it is not detrimental to any birds there.
