Sunday offered amazing viewing of several thousand Tundra Swans along Greenway Road just North of The Lambton Heritage Museum! There was also good viewing along many of the side roads in the area – we randomly took roads around the area and in every flooded field there were hundreds of Swans. These striking beauties migrate from the south to the Arctic to breed each year. They breed on lakes and ponds in Alaska and Canada, preferring wetlands and lakes with long shorelines where they feed on plant matter (and some mollusks and arthropods).
During migration we are lucky enough to have upwards of 15,000 birds stop-over in Lambton County for anywhere from 15 to 30 days. They began arriving on March 1 so there should be good viewing for at least one more week. Normally the swans will start to dwindle in number as early as March 8 with most gone by the end of March.
If you have the time it is well worth seeing these magnificent birds resting before their long flight north!
It has been an amazing couple of weeks with the return of Red-winged Blackbirds, Killdeer, Turkey Vultures, Common Grackles, Eastern Bluebirds, Eastern Meadowlarks, and Sandhill Cranes. We have been lucky enough to see all of these returnees and it makes us think of spring!
We saw our first Killdeers, Red-winged Blackbirds, Common Grackles, and Turkey Vultures in mid-February. On February 26 we were lucky enough to see three male Eastern Bluebirds looking to scout out the best habitat.
On March 1 we saw a pair of Eastern Meadowlarks – in full breeding colours – and they stayed around for three days! Their beautiful flute-like songs certainly made it seem like spring had arrived even though they were singing in the snow!
Also migrating through are the Tundra Swans and the Sandhill Cranes on their way to their summer breeding grounds.
Enjoy the sights and sounds of the returning birds – spring is just around the corner!
On a warm sunny winter day, if you venture outside, you may notice what looks like pepper sprinkled on the snow. Look more closely and you will notice that the pepper is moving! Indeed it’s jumping great distances for its size. Its common name is very apt as they can catapult themselves up to 100 times their own body length using an abdominal appendage called a furcular. This structure is what gives the group its name – Springtails. The furcular folds beneath the body and is held under tension until needed, once tension is reached the end slips out of a receptacle and snaps against the snow which throws the Springtail into the air.
Springtails play an important role in natural decomposition, feeding on decaying organic matter in the soil and thereby recycling nutrients for plants. They are able to withstand the bitter temperatures of winter thanks to a “glycine-rich antifreeze protein,” which binds to ice crystals as they start to form, preventing the crystals from growing larger.
Springtails belong to the subphylum called Hexopoda – six-legged arthropods. They are commonly called Snow Fleas but they are not related to fleas in any way! There are many species of Hexapoda in Canada and all are quite small, about one millimeter in length. They live in the soil where they are seldom encountered, however they can be extremely numerous with populations reaching 250,000,000 per acre.
So if you are out walking in the winter look in depressions in the snow where Springtails like to congregate. A foot print or other depression offers a microhabitat that is just a little warmer, is protected from the wind, and the snow is saturated with liquid water. And say thank you to these important little environmentalist for their help in recycling plant nutrients!
We enjoy canoeing on the Sydenham River in the spring and summer, but probably our favourite season for paddling this river is autumn. This year the month of October had warmer than normal weather and we took advantage of a forecasted picture perfect day with no wind and sunny skies for our last paddle of the season. Heading upstream (north) from near Wilkesport, the north branch of the Sydenham River begins where Black Creek and Bear Creek merge. Either of these tributaries is interesting so we paddled both. Trees on the riverbank were showing their fall colours and leaves floated on the river going neither north nor south as there is very little current this time of year. Temperatures were comfortable and the bright sun sparkled on the water’s surface.
Coming around the first bend in Bear Creek, we spotted a group of Wood Ducks in the water under an overhanging tree. They didn’t notice us and we were able to glide closer and see what we believe were first fall males along with adult males and females. It was a great juxtaposition between the young and mature males: the juveniles are colorful, but their feathers look scruffier. The adult male however is a gentleman of distinction; beautiful colors and smooth overall. Before we got any closer than 60 meters the group took off and headed upstream. We saw them again from a distance, but then they were wary of us and we never got close again.
Great Blue Herons were abundant on both creeks; we observed at least five individuals, all immatures. These birds typically enjoy having long sections of the river to themselves and in some cases they clearly didn’t appreciate the proximity of other Herons, vocally scolding the heron who encroached into their range. We were lucky enough to watch a Great Blue Heron catch a fish; close enough (40 meters) for decent photos but far enough not to disturb the bird. The herons stand motionless, and then lunge into the water with startling speed to snatch an unsuspecting fish.
The Herons also put on quite a show in flight, with their plumage reflecting the bright blue sky and fall colored leaves in the background. It’s amazing to see the way individual flight feathers are used when the bird is landing.
Great Blue Herons have specialized feathers on their chest that continually grow and fray. The herons comb this “powder down” with a fringed claw on their middle toes, using the down like a washcloth to remove fish slime and other oils from their feathers as they preen. Applying the powder to their underparts protects their feathers against the slime and oils of swamps.
Great Blue Herons are excellent fishers. They exhibit great patience, standing very still in shallow water or on the shore, waiting for a fish or frog to stray too near. Sometimes the Herons stand on one leg, which doesn’t appear to affect their ability to remain motionless.
For the most part, despite the near silence of a canoe, it’s hard to approach ducks much closer than 75 meters and the Mallards we saw were no exception. At the first glimpse of the boat they would burst into the air in a flurry of water drops and wingbeats.
Along the riverbanks we observed numerous small birds, Ruby-crowned and Golden-crowned Kinglets, Yellow-rumped Warblers, Robins, a few different species of Sparrows, American Goldfinch, Belted Kingfisher, Northern Flicker, Red-bellied Woodpecker, Red-tailed Hawks, Turkey Vultures, Eastern Phoebe, Northern Cardinals, Blue Jays.
After five hours of paddling up and downstream, we were back to where we put in, a Red-tailed Hawk soared overhead in a cloudless sky making his trademark shriek. Another awesome fall canoe trip was over. We highly recommend canoeing the Sydenham; it’s truly a hidden gem of Lambton County. For more information on this river and how to locate the boat launch site, please refer to our post from last year: http://lambtonwildlife.com/blog/natural-areas/paddle-the-sydenham-river/
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).
Ontario Nature organized a wonderful day to thank both Lambton Wildlife and the Sydenham Field Naturalists for their generous donations that helped make the purchase of 193 acres along the Sydenham River possible. On September 17th members of both clubs were invited to visit the site and enjoy a hike to the largest Sycamore tree in south-western Ontario, tour the south side of the property to look at the great variety of flora and fauna (led by Larry Cornelis, a member of both Nature Groups and driving force behind the acquisition of the property), and to hear from experts about the many species of fresh-water mussels that are found in the Sydenham River.
This property is now known as the Sydenham River Nature Reserve and is an incredibly important land acquisition that will forever protect the many endangered species that are found in and around the Sydenham River.
Justin Nicol, co-president of Lambton Wildlife and a member of the Sydenham Field Naturalists thanked Ontario Nature at the end of the day for the opportunity to hike the property and for providing a wonderful lunch in a beautiful setting.
Below is an excerpt from the Ontario Nature Website:
Thanks to you, the Sydenham River Nature Reserve is a reality. Ontario Nature has purchased a spectacular 193-acre property – forever protecting one of Ontario’s most biodiverse waterways. Located in the Carolinian Life Zone, this new reserve brings Ontario Nature’s province-wide nature reserve system to 25 properties and more than 7,000 acres.
The new reserve saves a ribbon of extraordinary diversity of plants and animals in a region that is under intense pressure from development driven by hosting 25 percent of the Canadian population.
The reserve represents some of the provinces best remaining examples of imperiled and vulnerable habitats. An almost two-kilometer stretch of the Sydenham River winds through the middle of the property. Representing Ontario Nature’s first riverine reserve, the property is teaming with life:
- 23 species at risk including birds, plants, reptiles, fish and, of course, freshwater mussels;
- 34 species of mussel, 11 of which are listed as at-risk provincially or nationally making the property the freshwater mussel capital of Canada;
- Two-thirds of Canada’s non-marine reptiles including the at-risk eastern spiny softshell turtle; and
- Half of Ontario’s bird species breed in or pass through the area during migration.
In 2014, two member groups – Lambton Wildlife and the Sydenham Field Naturalists – alerted Ontario Nature about a special property on the mussel-rich Sydenham River that was up for sale. After some initial discussions and exploring the property, in February 2016 Ontario Nature signed an agreement to purchase, pending raising $860,000.
The new Sydenham Nature Reserve was announced on December 19, 2016 after those funds were successfully raised. Many individuals, foundations and organizations gave generously in support of this effort. Lambton Wildlife and the Sydenham Field Naturalists were instrumental in the fundraising, and now share the responsibility to steward the property with Ontario Nature.
This riverside property is a largely-wooded biodiversity oasis in a landscape dominated by cash crops such as corn and soybeans. It forms part of the Carolinian Canada Sydenham River Signature Site, so designated because it was identified as a critical natural area. There are major challenges conservation organizations face in sustaining the ecological connections and biodiversity along the river corridor.
The reserve is open to visitors and Ontario Nature is already planning to create new trails so that the public can explore this extraordinary landscape without damaging sensitive flora and fauna. The best way to explore the property is by canoe. If you have any questions, please contact Ontario Nature at firstname.lastname@example.org or 416-444-8419.
Point Pelee National Park is a spectacular park to visit in any season, especially known for its spring and fall migration and its incredible biodiversity. Seven Lambton Wildlife members were fortunate enough to camp there from September 6th to the 9th.
Where to begin …. The best place to begin is to say a big THANK YOU to Paul Carter who did an outstanding job organizing the camping trip. His expertise, along with the expertise of Larry Cornelis, was truly appreciated by everyone. Each time we have the opportunity to hike with Paul and Larry we learn so much!
You will notice that in the photo Paul and Larry are sitting in red Adirondack chairs. The Red Chair Experience began three years ago in Gros Morne National Park, and it is a way of connecting Canadians with nature in our country’s most unique and treasured places.
During our stay we were lucky to see many of the species of flora and fauna that Point Pelee has to offer.
We saw numerous monarch butterflies, which was encouraging because we all know that these butterflies are struggling as a species (keep planting those milkweed!).
We were treated to many other butterfly species including Common Buckeye, Giant Swallowtail (caterpillar photos below), Red-spotted Purple, Painted Lady, and Crescent.
A highlight of the trip was seeing numerous five-lined skinks! These beautiful animals are Ontario’s only lizard species. They have scaly skin like all lizards and are fast, agile and prefer warm, dry habitats.
Dragonflies and Damselflies
There are a great number of species of dragonflies and damselflies in Point Pelee National Park. Two notable ones that Paul pointed out were the Carolina Saddlebags and the Lance-tipped Darner – both lifers for us! Some of the more common ones included orange bluets (?), twelve-spotted skimmer, and Common Green Darner.
We were surprised to see a Melanistic Garter Snake just outside the canoe rental shop at the Boardwalk trail. The melanistic color morph is a relatively common color morph that occurs naturally in the wild. Another great find was a Northern Water Snake – if you look closely at the photos you will see that it had recently enjoyed a meal.
We were treated to a number of wonderful bird sightings that included both migratory and resident bird species. It is hard to beat seeing fledgling birds. The first photo is of a fledgling cedar waxwing that one of the campers spotted at the Cemetery entrance. Other birds included immature and adult Bald Eagles, Osprey, Magnolia Warbler, Black and White Warbler, Hooded Warbler, Blue-grey Gnatcatcher, and Wild Turkey.
There is so much to enjoy at Point Pelee National Park – we hope that seeing some of the beauty of the park will inspire you to visit it soon!
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…)
