Happy Birthday Rondeau!

Today marks the 126th birthday of Rondeau Provincial Park. A year ago we had a nice celebration of former and current park staff, as well as numerous visitors. This year, with the park being closed, there is no on-site celebration, and in fact most people won't even be aware of this milestone at all, unless you are reading about it here. So consider yourself one of the knowledgeable few.

All of the parks in the provincial park system, including Rondeau, have been closed since March 19. No one is allowed in at Rondeau, other than cottagers, although I have heard that some folks are ignoring the closed signs and status. They do so at their own risk, since the potential fines can be substantial.

I was last in the park on March 18, the day before it was closed as it turned out, so I can only imagine what might be happening over the last few weeks. With the spring bird migration normally in full swing right now, one can only wonder what might be arriving without being seen. Perhaps there would be some new species for the park checklist, and no one is there to document the event! In the meantime, I will dig into my photo files and provide some idea of what may have occurred.

The first two photos were taken earlier this year, just before the park was closed. The mood even then was sombre, perhaps a foreboding of the future closure, with the foggy light filtering through the still mostly dormant forest.


 Wood Ducks had appeared.
 The leaves of an uncommon orchid, Puttyroot, were still visible late in the winter. They will then dry up and disappear as the flowering spike then develops to be in flower in early June.
But as the spring slowly unfurled, here are a few things that have likely occurred, or arrived. Blue Jays were fairly common this winter. Some will have moved back north.
 American Robins have arrived in numbers outside the park, so one can only expect that there are many of them inside, busily carrying on with their usual routines.
 Eastern Towhees have arrived.
 Spring wildflowers are emerging, such as Bloodroot, one of the earliest.
 Sharp-lobed Hepatica, as defined by the pointed leaf structure, will have undoubtedly almost finished by now.
 Spicebush is an abundant shrub, thriving in the damp soils that are so common at Rondeau. There is often a yellow hue to the forest understorey about now, indicating the abundance of this fragrant shrub.
 Dutchman's Breeches are common on the higher, drier parts of the forested ridges.
 A somewhat rare plant, Wood Violet, should be in flower in the next few days. It only occurs in a few small spots in the more northerly parts of Rondeau. Will anyone be able to enjoy it this year?
 ....or that of the diminutive False Mitrewort, the delicate flowers of which are barely half a centimetre in diameter?
 Red Trillium is not nearly as common as its white, provincial counterpart, but is widespread and as their average first flowering date is about May 4, should be in flower right now.
 Sometimes there are unusual forms of the Red Trillium to be found, such as this next one which I have seen on several occasions along the Spicebush Trail. Will it be there again in 2020, or has it completed its life cycle never to be seen again?
In another couple of weeks, this declining orchid will be in flower. Although its name is Showy Orchid, it is small and anything but showy unless one gets down to its level for a close-up view.
Of course birds are one of the things that many people look forward to at hotspots like Rondeau right about now. Undoubtedly they will arrive as usual, but will they notice the lack of birders with binoculars pointed in their direction? Probably not, I'm thinking. These first two species are some of the almost 40 species of warbler recorded at Rondeau, and are pretty common any year.
Chestnut-sided Warbler

Black-throated Green Warbler
 And then there are the less common ones, that always get a little more attention when they are found, such as Hooded Warbler....
 ....and including, of course, the unofficial bird of Rondeau, the Prothonotary Warbler. Rondeau remains the provincial, indeed the national, stronghold for this dazzling warbler.

 Common Nighthawks aren't so common any more, and to find one cooperatively resting on a visible branch along a trail is always a treat.
 The Red-headed Woodpecker, which used to be fairly common, is now far less often seen anywhere in Ontario, although in any given year there may be one or two pairs of them still nesting at Rondeau.
 The White-winged Dove has been back for a few weeks now so I am told. If its past behaviour is any indication, it will still be easily found by the time the park (hopefully!) opens up again.
As May continues, there will be other highlights, including an array of colourful butterflies flitting along the trails.
Eastern Tiger Swallowtail
 So regardless of the current closure of the fabulous natural areas that we tend to enjoy, and to some extent take for granted in both the Provincial and National park system, it is some consolation to know that nature will likely thrive nonetheless. In fact it is almost certain that there will be far fewer road killed critters adorning the roadways!

The sun will rise again and it is just a matter of time before we can enjoy these special places.
In the meantime, stay safe, and

Happy Birthday Rondeau!

Natural Areas of Chatham-Kent, Part 10 (Blenheim Sewage Lagoons)

Okay so the idea of a sewage lagoon maybe doesn't sound like much of a natural area. But wildlife have a different perspective, and therefore a complex of sewage lagoons is very much a magnet for wildlife.

If anyone has been out in the prairie pothole region of North America, you may realize that potholes filled with water are common place. Certain types of wildlife in particular are attracted to these potholes. So to wildlife passing through Chatham-Kent, and other areas where sewage lagoons are present, this concentration of 'potholes' filled with water are ideal places to visit, and in some cases nest at. As a result, some species historically found much farther west, have expanded their range to include sewage lagoons in southern Ontario.

These lagoons are easy to find for humans, as well. This particular set is located just west of Blenheim and north of Hwy 3/Talbot Trail on, appropriately named, Lagoon Road.

There is a condition for visiting, however, and that is an annual permit which is required to ensure not just anyone goes in and to protect the municipality from liability. The permit system has been in place for these lagoons since the mid 1980s, and is available from the municipal centre in Blenheim, located next to the post office.
To date there have been ~235 species of birds recorded here. What is so attractive to wildlife? I'm glad you asked.

Water birds, especially ducks, need places where they can rest safely from terrestrial predators.



Ducks, herons and shorebirds can feed on the abundant aquatic life, including invertebrates, fish, frogs, etc.
Shorebirds of various types are abundant especially during the spring and fall, including the Spotted Sandpiper shown above and Lesser Yellowlegs shown below.
Sometimes shorebirds can be extremely abundant.
Others are regular, but less common.
Short-billed Dowitcher
Long-billed Dowitcher
Wilson's Phalarope
 Wilson's Phalarope is really a species of the prairie pothole region, which has nested at these sewage lagoons on occasion. In the photo of them below, in their breeding plumage, it is the female that is the more brightly coloured, as it is the male that does most of the incubating.
Still other shorebird species are unusual, and if they occur immediately attract interest from other keen birders.
American Avocet
Buff-breasted Sandpiper
Marbled Godwit
Species of ducks that are more typical of the mid-western regions are more common place now, and include the following two species, both of which have attempted to breed here:
Northern Shoveler

Ruddy Duck

The next species, Greater White-fronted Goose, does not breed, but is sometimes seen on migration.
 It is sometimes called speckle-belly, due to the pattern of its belly shown here.
The waters of a sewage lagoon are nutrient rich, as one might expect, and this means aquatic insects are abundant. Land birds such as swallows benefit immensely from insect hatches. This is most evident during periods of cool weather when insects might not be available over the land, but with the warmer water retaining heat and with multitudes of insects hatching and becoming air borne, swallows can feed over these ponds to sustain themselves at a critical time. If one wants to see this, visit the lagoons during a cold spell. For example during a cold spell in mid-May of 2017 when the temperatures dropped close to freezing, there were thousands of swallows swooping over the water feeding, or resting on the berms separating the ponds.
 Tree Swallows were the most abundant, but Cliff Swallows and others were present in larger than usual numbers.

The shrubs surrounding the lagoon complex can be a great spot for land birds, especially on migration.
Rusty Blackbird

With such concentrations of birds, raptors that feed on birds such as Peregrine Falcon, are periodically attracted to the site.

Other species of wildlife are found, as well, with some being rare.....
Cattle Egret
 ...some uncommon....
Short-eared Owl
....and some not so rare.
Groundhog
The very openness of the lagoon complex and with it being so accessible to birders due to the berms surrounding the ponds, make it a great spot for birders. Having said that, since it is easy for humans to see wildlife, keep in mind that wildlife, which have great vision and survival instincts, can see humans even better and may be difficult to approach. Binoculars are a must, and a scope is highly recommended.
With all of the openness, there are lots of wildflowers present around the edges, making it a great spot for butterflies as well. It is a regular stopping point for us in our annual Butterfly Count in mid July, but it is sometimes better in the late summer when plants such as New England Aster, which is a favourite nectaring plant for butterflies, are abundant. The first three species are common here, as are others.
Clouded Sulphur
Common Ringlet
Orange Sulphur
 The next two species are rare and irregularly found here in spite of their names.
Common Buckeye
Common Checkered-skipper

All in all, sewage lagoons are a great place to find wildlife......you may be surprised!
