The other day I looked out on the pond and there were two ducks sitting on a log beside a drake mallard. They had a lot of white on them and at first I thought they might be domestic mallards from a nearby farm. But they weren’t.
I had to run upstairs to get a bird book as I didn’t recognize the birds, having never seen this particular species before in full breeding plumage. So another new species recorded on our pond! They were, by the way, northern shovelers, a duck that’s apparently abundant during the breeding season in the prairies, the Yukon and Alaska.
Although Kenora is only a couple of hundred kilometers for the eastern edge of the prairie ecosystem, we don’t see a lot of what is in that biome, or only rarely.So It was great to see the shovelers, even though they didn’t hang around for too long. My bird guide indicates they migrate through and breed in the area, but I haven’t met anyone who has ever run across a nest or a young brood of shovelers here. I’ve met people who have seen theme here on occassion, mostly in the spring.
They do resemble a mallard, except for a bit more white and the extended, black bill that sort of looks like it was squashed in an early stage of development with a hammer.
Given its large, spatula shaped bill – some refer to them as ‘spoonbills’ – it didn’t surprise me when I read that it “has the most unusual feeding habits of any duck.” If has a fondness for phytoplankton as well as zooplankton, sometimes feeding on the surface in deep water in lakes devoid of aquatic vegetation. To strain for plankton, water is ingested at the tip of the bill then jetted out at the base. Given it likes plankton, it’s no wonder they are known to gather in large numbers on sewage lagoons. Maybe that’s one of the reasons they aren’t exactly held in high esteem as table fare . . .
There’s not a lot of plankton in our pond, especially at this time of year, but there is a lot of insect life, the likes of which makes up about a quarter of the shovelers diet. As animal life is high in protein, it makes sense this species might stop in at our pond for a quick, nutritious meal before moving on. Seeing these birds were on our pond in late May, it’s likely they were drakes that had abandoned their mates; drake shovelers leave their mates as early as the first day she begins to incubate, although some stick it out until the eggs are hatched. In nearby Manitoba, shovelers usually commence nesting in early May.
By the way, the sora rails have also returned to the pond. Hopefully the summer and fall will bring some other species I haven’t yet seen from the deck. I’ll keep you posted.
