Fall is a spectacular time to paddle! We were fortunate to have a picture perfect day to canoe through the Sydenham River Nature Reserve.
The water levels were very low (see below) which meant getting out of our canoe often but both the weather and the water were very warm. In the spring the water level is high and there are rapids and a swift current to contend with so this would not be the time of year for novice canoeist to paddle through the Reserve.
Picturesque scenery was the word of the day and we enjoyed an interesting array of flora and fauna as we paddled.
The Sydenham River Nature Reserve is home to an incredible 34 species of mussel, 11 of which are listed as at-risk; making it the freshwater mussel capital of Canada! Freshwater mussels are the longest-lived invertebrates. They are living water filters moving as much as eight gallons of water per day in through their siphon and over their gills to get oxygen and food. This makes mussels exceptionally vulnerable to water pollution so the importance of keeping the Sydenham River and its ecosystem protected is of paramount importance.
Mussels move by extending their foot out of their shell and into the river bottom, then they retract the foot and pull themselves along. In the photo below you can see the furrow that this mussel has made as it moved to a new location.
One of the highlights of the paddle was visiting the huge Sycamore tree that is in the reserve. Ontario’s largest recorded Sycamore tree, near Alvinston, measures 263 cm at breast height.
The biodiversity found in the Sydenham River is impressive and we were thrilled to see so many butterflies, dragonflies, damselflies (including the American Rubyspot pictured below), waterfowl (a pair of American Widgeons are pictured below), and many other birds (the Bald Eagle pictured below flew past us several times and landed along the river to watch our progress).
If you plant it, they will come…
LWI members were privileged to be invited to visit the Enbridge Solar Farm, in Sarnia, on June 21st to observe how the restored tall grass prairie habitat has attracted rare bird species. Resident expert Larry Cornelis led this 3-hour outing. 28 members, including Larry, participated. The group included novice through to very experienced birders. Weather was ideal: clear, sunny but not too hot.
The Enbridge Solar farm is the largest in Canada and has a total of 257 hectares covered with 1,300,000 solar panels, enough to power 12,000 homes on a sunny day. Due to electrical grid limitations there will be no more panels installed on this site. The remaining 188 hectares of the Enbridge property have been designated for conversion to tall grass prairie and these areas were the subject of our visit. The very secure property is normally inaccessible to visitors so this was a unique opportunity to see these large grassland areas close-up.
The highlights of the outing were multiple sightings of Grasshopper and Clay-colored Sparrows. Both rare species were observed in the tallgrass prairie rehabilitated areas and these birds are evidence that restoring habitat does have the positive outcomes expected. Other bird species observed were: Killdeer, Brown-headed Cow Bird, Willow Flycatcher, Song Sparrow, Red-winged Blackbird, Savannah Sparrow, Tree Sparrow, American Goldfinch, Eastern Kingbird, Turkey Vulture, Cedar Waxwing, Meadowlark, American Crow, Yellow Warbler, Field Sparrow, Hairy Woodpecker, Great Blue Heron, Grasshopper Sparrow (3), Clay-coloured Sparrow (7), Mourning Dove, Common Yellowthroat, Starling, Common Grackle, Northern Flicker, Catbird, Indigo Bunting, Red-tailed Hawk, Robin, Yellow-billed Cuckoo.
Kudos to Larry for organizing and leading this activity, it really was an awesome day! A special thank you to Enbridge for allowing us to visit the property and for planting this habitat. Indeed it is encouraging for all naturalists to see the relatively short term effects of planting tall grass prairie. Imagine what might be possible when other land areas are restored in this manner.
There are some wonderful nature trails near Port Franks that are worth a visit. The trails wind through the large Lambton Heritage Forest and there are a couple of ways of accessing them. The first trail we explored starts out from Outer Drive. There is a 911 address sign for the trail, number 7101, and the trail access is located on the north side of the road just before the road curves sharply to the right. At the time of year that we walked this trail (early June), there were plenty of mosquitoes, so apply repellent generously before heading out. Consider using one which also helps to protect against ticks. The trail is easy to moderate, with a few slopes, and forms a loop that’s perhaps 1.5 kilometers long. Most of the wildlife we sighted was on the first half of the loop, the section to the left. There is a nice bench to sit and relax on at the midpoint. The trail also connects to another trail that we didn’t fully explore. (more…)
After seeing multiple e-Bird alerts for the Dickcissel, we headed out in the morning on Friday for a short drive south to try and find this rare bird. We found the birds on McCallum Line just a bit west of Brigden Road. (more…)
A large flock estimated at 500 of Lapland Longspurs was observed on Moore Line in Lambton County on April 26. The birds were foraging in the stubble of agricultural land. The number of birds is more evident when they fly up together. These birds should be well on their way to the far north by now.
One of the things that the LWI blog posts can be used for is to share Lambton County wildlife sightings with other LWI members. The LWI community is always yearning to know as much as possible about nature in Lambton County, and when you see something interesting it might be nice to write a brief post. Of course providing information on the exact location of nests or vulnerable things should be avoided.
Here is an example short post based on a sighting that we experienced back in September:
Yesterday, while on our way to Hawk Cliff, we spotted two fox kits sunning themselves in the grass along the side of highway 80 near Alvinston. We stopped the car and turned around and were able to snap some photos, before one of the pair trotted off, while the other paid little notice to us. Their behavior suggested that they may have been orphaned or separated from their mother.
Looking at their coats they weren’t as luxurious as we would have expected an adult fox to be and they look a bit skinny, but perhaps this is consistent with being adolescents and the season. Maybe some other LWI members will spot this pair too. If you are in the area of highway 79 and highway 80 intersection, keep a look out!
