WRN Outing to the North Shore of Lake Ontario

Birds suddenly became a daily excitement for me, a passion, and contact with birds in one way or another, became as necessary to me as food.

Participants: Miriam Bauman, Jim Bowman, Martin Clemens, Dave Collins, Mary Collins, Lisa Den Besten, Heather DeYoe, Nas DeYoe, Helen Fowler, Victoria Ho, Sonja Klisch, Christina Koenig, Kuldip Malhotra, John Markvart, Melinda Metzger, Pam Sadler, Selwyn Tomkun, Marcus Wu.

     It was a foggy morning and visibility was a challenge when we set off.

     Fortunately, as the sun came up the fog burned off and by the time we gathered for a group picture we had great visibility.

     

DesJardins Canal, Dundas, ON

     Dave and Mary had arrived early and Dave had already done yeoman work with his camera, capturing the following excellent shots of Black-crowned Night Heron (Nycticorax nycticorax), both adult and juvenile.

     It was fortuitous that Dave had been able to get a shot of the juvenile. As we rounded the corner at the canal I spotted both birds on a snag, but by the time we had corralled everyone from the parking area and made our way back, the juvenile was nowhere to be seen.

     Melinda got a couple good shots of the adults, too.

     A Great Blue Heron (Ardea herodias) was also in the vicinity, working the intake of the culvert and hoping for breakfast.

     A couple of female Hooded Mergansers (Lophodytes cucullatus) disported and preened, dove and surfaced, nibbled on a small fish or two and generally seemed to be enjoying life.

     Ring-billed Gull (Larus delawarensis) is our most common gull. They seem to know how splendid they are and never seem reluctant to pose for a picture.

     The weather is still exceptionally warm in southern Ontario (by mid afternoon it reached 26 degrees) and Double-crested Cormorants (Nannopterum auritus) were present.

     As long as there is open water a few even remain through the winter.

     Hairy White Oldfield Aster (Symphotrichum pilosum) enlivens dull areas of waste ground at this time of year.

     Here I am pointing out something of interest; I can't remember what.

     This site was formerly a disused and much abused industrial wasteland and it has been converted into a wonderful little nature preserve.

     The chimney was left standing for Chimney Swifts (Chaetura pelagica) and has been occupied by these endangered birds for at least the past couple of years.

     Many nest boxes have been installed and it is not surprising that House Sparrows (Passer domesticus) have moved in to claim their share.

     Heather is always keen to score the heron trifecta so, having already seen Great Blue and Black-crowned she was very happy when Victoria spotted a Green Heron (Butorides virescens).

     The observation deck is a fine, robust structure - a great addition and a significant vantage point for wildlife viewing.

     Floating islands provide resting spaces for many species, including this pair of Mallards (Anas platyrynchos).

     Eastern Phoebe (Sayornis phoebe) is the hardiest of all flycatchers, arriving early and leaving late.

    Brown-lipped Snails (Cepaea nemoratis) were everywhere one looked; at times it was difficult to avoid stepping on them.

     Hickory Tussock Moth (Lephocampa caryae) caterpillars were ubiquitous.

     They will pass the winter as a pupa in a loose cocoon spun in leaf litter. The settae are actually woven into the cocoon. 

     We were all overjoyed to see a Pied-billed Grebe (Podilymbus podiceps) still inhabiting the canal.

     The Urquhart Butterfly Garden is at the end of the canal, and while there is not an abundance of butteflies in late September, it is a beautiful spot, and always worth checking.

     A Virginia Creeper (Parthenocissus quinquefolia) seems anxious to establish a close relationship with a nearby tree.

     The floral display, even beyond the effulgence of summer, still evokes great pleasure.

     Dust off a rock and sit a while.

     American Goldfinches (Spinus tristis) have already moulted into drab winter garb.

     As we made our way back to our cars we noted a Dekay's Brownsnake (Storeria dekayi) who had paid a high price for straying onto the road.

Grindstone Creek, Hamilton, ON

     Amur Honeysuckle (Lonicera maackii) is yet another example of our folly in introducing alien species into our native flora.

     It is native to temperate Asia and has escaped from cultivation to become a significant invasive species.

     The water level in Grindstone Marsh was quite low and several Lesser Yellowlegs (Tringa flavipes) were seen feeding on the mud and in shallow water.

     We also encountered our first Trumpeter Swans (Cygnus buccinator) here.

     As though in homage to its name a lone Solitary Sandpiper (Tringa solitaria) probed for tasty morsels.

     I wondered if the people going by on the train were longing to be out enjoying nature like us.

     Many Killdeer (Charadrius vociferus) were present.

     A female Green-winged Teal (Anas crecca) sifted for food, behind a Ring-billed Gull.

     I find this description of Green-winged Teal by F.H. Kortright exceptionally charming, "A wealth of delicate loveliness is blended on the tiny person of this, the smallest of our wild fowl."
     An American Herring Gull (Larus smithsonianus) was determined to find a way to eat this fish.

     A bevy of Ring-billed Gulls seemed content to not do much of anything.

     A Wood Duck (Aix sponsa) is truly a remarkable bird. One can only wonder at the selective pressures of female choice in developing this extravagant plumage.

     For those cognoscenti of beautiful ducks, here is a book to set your heart aflutter.

     A Downy Woodpecker (Dryobates pubescens) entertained us all.

     Many Ospreys (Pandion haliaetus) have already left, perhaps most, but a few still remain along the watercourses of southern Ontario.

     Not so many years ago, Great Egret (Ardea alba) was quite a rarity in our wetlands, but in recent times it has multiplied and prospered and is no longer an uncommon sight.

     A Great Blue Heron was patiently waiting for suitable prey to come within striking distance.

     I have seen You Tube videos where a heron will capture and swallow a duck so those teal and wood ducks had better not stray too close!

     A Western Honey Bee (Apis mellifera) with full pollen baskets, here on New England Aster (Symphyotrichum novae-angliae), had obviously enjoyed a productive morning and soon will be returning to the hive.

     Looks like the authorities are getting serious about not feeding wildfowl - better let all the grandmothers know!

LaSalle Park and Marina, Burlington, ON

     Sonja was determined to make friends with a Trumpeter Swan, and given their association with humans at this location there is a good chance of doing so.

     Waterbirds have a tendency to gather together in quiet sheltered coves and in the following picture, if you look carefully you will see Mallard, Ring-billed Gull, American Coot (Fulica americana), a male Hooded Merganser and a female Common Merganser.

     Miriam and Victoria were enjoying each other's company on a pleasant walk through the woodland, with many birds.

     As might be expected, Black-capped Chickadee (Poecile atricapillus) was very common, soliciting food from friendly humans.

     White-breasted Nuthatch (Sitta carolinensis) was almost as common and equally persistent.

     A Brown Creeper (Certhia americana) was partially hidden most of the time, revealing tantalizing glimpses, only to disappear around the trunk as cameras were raised.

     Melinda obtained this very acceptable shot.

     She also did well with a Northern Parula (Setophaga americana). 

     This male Northern Cardinal (Cardinalis cardinalis) was drying off after a feather-cleaning bath.

     Dave also captured this young male, no doubt admiring the plumage he will one day acquire. 

     Canvasbacks (Aytha valsineria) have already occupied Lake Ontario, fresh from their breeding haunts in the north.

Photo: Dave Collins

     There were many Common Mergansers (Mergus merganser) present, most basking in the sun.

     This individual was searching for food, no doubt.

     A Mute Swan (Cygnus olor) is a beautiful sight. In the water.....

     ..... or in the air.

     LaSalle Park is generally a reliable location for American Coot.

      A male Hooded Merganser is proof that male waterfowl are, in general, stunning birds, blessed with charm and charisma.

     Pam was eager to get some practice using a telescope.

     A Downy Woodpecker rapped on a tree behind her and obligingly moved into position for a portrait.

Photo: Dave Collins

     Wooly Bear caterpillars, the larvae of Isabella Tiger Moth (Pyrrharctia isabella) are searching for secluded, well-protected locations to pass the winter.

     Lisa could not resist one last chance to interact with a Trumpeter Swan - and who can blame her?

Paletta Park, Burlington, ON

     It was a hot day and Miriam decided to take a break at this location, so I am grateful to Dave and Melinda for pictures.

     There were little pockets of warblers moving through, but frustratingly difficult to see well, let alone photograph.

     Dave did manage this shot of a Myrtle Warbler (Setophaga coronata).

     Melinda meanwhile trained her camera on a Yellow-bellied Sapsucker (Sphyrapicus varius) working assiduously on the bark of a tree.

     We came across a fine specimen of Lepiota acutaesquamosa and Dave obligingly photographed it for me.

Bronte Harbour, Oakville, ON

     We had not known that there was a community festival being held at Bronte Harbour, with all manner of booths, vendors and festivities, music and throngs of people. We had to drive round and round even to find a parking spot, and some gave up and headed for home.

     As you might imagine, the birding activity was minimal, but we did manage a few shots.

     A Pied-billed Grebe seemed unconcerned by the  frenetic activity and spent its time in the inner harbour.

     It was joined by a Canada Goose (Branta canadensis).

     This macaw was indifferent to the clamour going on around it.

     The salmon are running at this time of year, and it appeared that someone had been using roe as bait and left it to spoil in the sun.

     It is quite clear that this cormorant had been happy to see us and was waving goodbye with a vigorous clap of its wings.

     It was a great day with a splendid group of people. Many thanks to Dave and Melinda for contributing their pictures and consenting to their use on my blog. All other pictures were taken by Miriam, of course.

     À la prochaine, mes amis.
