     When we left home it was a crisp minus fourteen degrees but the forecast was for a pleasant day with the temperature climbing to around zero before the day was out. We met at our normal spot, car-pooled to the extent possible and set off for a fine day of birding.  Old friends and new arrived, club stalwarts and welcome guests, all with the goal of enjoying a fine day with many birds to keep us company.

     As has become customary on this outing, our first point of call was at the DesJardins Canal in Dundas, where the signature bird at this time of the year is Hooded Merganser (Lophodytes cucullatus). We were not disappointed.

     For some this was a lifer and they were exceptionally happy to see this handsome duck.

     A couple of Redheads (Aythya americana) were also seen swimming among the ubiquitous Mallards (Anas platyrhynchos).

     There was also a good number of Canada Geese (Branta canadensis) on the canal, open water of course being a major draw for waterfowl in winter.

     In fact, given the succession of cold nights we have experienced recently, I was afraid that finding open water might be a problem, but the flow in the canal is obviously sufficient to prevent ice from forming.

     This was not to be the case at LaSalle Park and Marina and we were greeted by ice across Burlington Bay, with barely a single patch of open water.

     Obviously this had an effect on the number of species present.

    Trumpeter Swans (Cygnus buccinator) had no hesitation about venturing out onto the ice, but certainly there was nowhere for them to feed, and supplements of corn are provided under such dire conditions.

     Ring-billed Gulls (Larus delawarensis), resourceful as ever, find ways to make a living, and are resplendent, beautiful and unappreciated by many.

     In a tiny ribbon of water at the very edge of the lake, ducks and geese congregated together, with a few diving ducks mixed in with the dabbling ducks, including this female Common Goldeneye (Bucephala clangula).

     One of the greatest pleasures for a naturalist, young or old, is to feed a wild creature, whose confidence in you is rewarded with a zen moment of interconnectedness with other life forms on this wonderful planet we are slowly destroying. So it was for Logan.

     This youngster already has a firm connection to nature and I commend both him and his father, Sal, who spares no effort to nurture and encourage his interest.
     I am not quite sure which person is at the other end of this outstretched hand, but it was a matter of little concern for the Black-capped Chickadee (Poecile atricapillus) coming in for food. Human and bird in harmony - now there is an image for the ages.

     Downy Woodpecker (Dryobates pubescens) is a resident species and is familiar to all.

     Ice and snow are no deterrent to a hardy woodpecker, nor to swans, ducks and geese it seems.

     The contrast between the native Trumpeter Swan and the introduced Mute Swan (Cygnus olor) is shown in the following two images.
     

     Actually the Trumpeter Swans seemed to be engaged in a ritualized display, possibly portending courtship, for there was no aggression at all, and several birds took part in the ceremony.

     No doubt this handsome male Greater Scaup (Aythya marila) had affairs of the heart on his mind too.

     Common Goldeneyes were well charged up with hormonal urges and both males and females were engaged in courtship displays.

     This fine male would no doubt have great genes to pass on to the next generation.

     We left LaSalle and moved onto to Paletta Park where warm, clean washrooms awaited the ladies, who especially appreciate such comforts in winter. After a quick lunch eaten mainly in our vehicles we strolled down to the water.

     Ring-billed Gulls were resting on the ice, a behaviour which nearly always elicits a question from someone about how they stay warm.

     Mallard was far and away the most common species, ever handsome, ever hardy, ever resilient and pleasure-giving, but seldom appreciated due to its familiarity.

     At Paletta Park we saw a couple of Hairy Woodpeckers (Dryobates villosus), the only location where we encountered this species.

     Our final stop for the day was at Bronte Harbour in Oakville and this proved to be the jewel in an already lustrous crown. Ice covered most of the harbour, save for a few very small areas of open water in the corners against the walls, and ducks were concentrated there, so close one could almost have reached over and touched them.

     Fraser Gibson, an eminence grise of Waterloo Region Nature to be sure, remarked that he had previously seen Long-tailed Ducks (Clangula hyemalis) only at a distance and was captivated to see them so close; one could actually see them swimming under water and emerging from under the ice.

     Greater Scaup was very common.

     Again it was possible to see both males and females at very close quarters and reinforce one's identification skills. The birds came to the surface after a dive, with mussels in their bill enabling everyone to see how they process their food.
    Bufflehead (Bucephala albeola) was not quite as numerous as other species, at least not close in, but some could be seen off in the distance riding the not insignificant swell of Lake Ontario.

     There were little flotillas of Common Mergansers (Mergus merganser) sometimes as many as twenty birds together swimming in a straight line one behind the other.

     Several White-winged Scoters (Melanitta deglandi) were seen but we were able to photograph the female only.

     In addition to occupying the sparse patches of open water in the harbour many ducks were on the lake side of the breakwater riding the roiling waves of a windy day on Lake Ontario. The picture below gives the impression of calm water but the swell was actually quite pronounced.

     It was with great pleasure that we saw many Redheads.

     This female Common Merganser was resting on an ice floe.

     On the way back along the breakwater we saw Red-breasted Merganser (Mergus serrator) surprisingly enough the only one on the day as I recall.

     Many people lingered for a while to observe the ducks at close range and really get the chance to appreciate their various behaviours and survival skills. It was really quite remarkable.
     We parted company having very much enjoyed each other's company and knowing that an enriching day had been had by all. Same time next year folks!
