The Teal Tale Teale Told

Some ducks make very different sounds than the traditional Mallard quack. On a return trip to the Big Creek conservation trail in Long Point, March 2022, I was quite intrigued to hear squadrons of ducks uttering whistle-type calls as they scooted about on the water or took to the air. These were American Green-winged Teal (Anas carolinensis), the smallest species of dabbling duck in North America, approximately pigeon-sized (Baldassarre 2014).

To hear what these small ducks sound like, here is a link to an audio recording of Green-winged Teals whistling: https://macaulaylibrary.org/asset/86925491.

Apparently, it is the males that whistle while the females produce quacks (Baldassarre 2014). Green-winged Teals breed across the boreal and deciduous forests of North America, preferring wooded wetlands. Their nests are very difficult to find, concealed among tall grasses or shrubs. These ducks migrate early in the Spring to the northern breeding grounds, and it’s likely that the Teals I saw in March were using Long Point marshes as a stopping ground on their way north.

Teals use their bills (and the fine toothlike combs at the edges called lamellae) to filter tiny food items from shallow water such as seeds and invertebrates. Unsurprisingly because of their overall small size, it seems that Green-winged Teals are particularly good at feeding on very small food items, as opposed to Mallards, which are more generalist feeders (Baldassarre 2014).

Two fun stories about the word ‘Teal’ to finish off with. One is that, according to wikipedia teal is a word that originally meant “small dabbling duck” or something like that and was applied to several species of ducks before it was applied to the blue-green colour*, because of the bright “teal” markings on the wings (and heads of the males).

*I can’t find this mentioned in my books about ducks or anywhere well-sourced. I believe it to be true and fascinating but wikipedia is the main source I can find this fact on, so take that how you will.

The colour on their wings and heads really is quite beautiful.

My other anecdote about Teals I would like to share is about one of my favourite nature writers, Edwin Way Teale (it’s also the reason this post has a Dr. Seussian title). In his book, North with the Spring (Teale 1951), he tells of a time when his naturalist ways came under suspicion by the law. He and his friend had been out one winter day, watching ducks at a pond. Across the pond was a building which used to be a military plant, and I guess the fear of foreign spies caused a local to report the pair of men staring in that direction with binoculars.

As Teale himself says: “The dialogue that ensued when the first officer reached us might well have been a skit on a vaudeville stage.

“What are you doing?”

“Looking at ducks.”

“What’s your name?”

“Teale.”

By the light in his eye I could tell he had heard about teal ducks. The light said: A wise guy, eh?

I have friends who are named Crow, Crane, Raven and Rook. Fortunately, they were not along that day.” (Teale 1951, p. 288).

In case you forgot that Green-winged Teals are small… here are some swimming near a Canada Goose for comparison.

Return of the Ravens

Ravens are awesome, beautiful birds.

My parents’ farm property in Norfolk County has been blessed by the construction of a very exciting nest. One day when I arrived at their house and opened my car door I was greeted by the distinctive “croak” of a Common Raven (Corvus corax). The sound startled me, placing me in the woodlands of Algonquin Park, but there was no mistaking that call, and the size of the bird making it. I could see the calling raven, perched atop an unused silo. As exciting as this brief sighting was, the true significance of this bird’s presence was not yet revealed.

Later that same week, my Mom asked about the large crows and mentioned that they were building a nest on top of the silo. She said they went back and forth with sticks in their beaks. Maybe this news wouldn’t be so exciting to some people but for myself the thought of a raven nest that I could regularly observe was exhilarating.

And observe it I have!

On a recent visit, I went back to check out the nest and take some pictures. After only a few moments of watching the silo, I heard the sounds of one of these amazing birds returning and saw it carrying a  large stick in its beak. The raven dropped the stick onto the nest pile without even landing, continuing to soar through the sky on its powerful wings. Apparently, if a dropped stick doesn’t stay in the nest, the ravens won’t pick them up again off the ground (Stokes and Stokes 1989). The sticks are taken from tree branches, broken off by the ravens, not collected from the ground (Stokes and Stokes 1989). In addition to large sticks, the nest could contain dirt and grass clumps as well as an interior lining of gathered hair or bark (Stokes and Stokes 1989).

The raven didn’t even land, just dropped the stick from the air onto its nest.

A few minutes later, a turkey vulture (Cathartes aura) came drifting towards the silo. The large bird seemed to be planning to perch atop the silo, something I have seen vultures do previously. Swooping onto the scene with deep throaty “croaks” the raven pair chased the vulture off into the distance, something that was reminiscent of the classic behaviour of corvids mobbing raptors or owls.

As I said at the beginning of this post, the call and sight of ravens makes me think of Algonquin Park, and that’s for good reason. Until now, it was the only location I had seen these birds. Ravens used to be common across all of Ontario but mainly due to habitat destruction and human persecution, they have been mostly absent from far southern Ontario for about a century (Cadman et. al. 1987). Ravens were even rare in Algonquin Park until the 1960s because of the poisoned baits left out for wolves (Tozer 2012). The most recent field guide I have (Bezener 2016) still has the raven range map cut off before reaching most of Southern Ontario.

I’ve tried unsuccessfully to find a good source for the current breeding range of ravens in Ontario, but I suppose I’ll have to wait for the next edition of the Breeding Bird Atlas, which is collecting data right now (2021-2025) for its creation. It’s an amazing project, and if you have the time to contribute go for it! Suffice to say, this nest of ravens is a fairly new thing in my area and is very exciting. I hope that they have a successful nesting season, and I have a feeling I will have more posts about this nest in the future! At the time these observations were made (March 29, 2022) the ravens have possibly already laid eggs in the nest, as Tozer (2012) gives a range for Alqonquin raven egg-laying as March 20 – April 19. Stay tuned!

3. Canada Jay (Perisoreus canadensis)

Subject: Canada Jay (Perisoreus canadensis).

Location: Algonquin Provincial Park.

Date: March 2017.

For an Introduction to this series (my Top 20 Nature Photos of 2013-2020) go here.

The Story Behind the Shot: I’ve only visited Algonquin Park in the Winter twice. On this occasion, in March 2017, I was actually searching for this particular bird (one of the rare times that I have a target species in mind, I’ll be recounting another one for my next photo). The Canada Jay had only recently been rebranded as such, the common name used to be the Gray Jay and some people still refer to it as such (after all, common names can sort of be whatever you want them to be). Part of the name-change or name-shift was to do with a campaign by the Canadian Geographic Society to name the Canada Jay (Perisoreus canadensis) as Canada’s National Bird. For more information about this story, see the Canadian Geographic article here: https://www.canadiangeographic.ca/article/meet-our-national-bird-gray-jay. Having read up on this story I wanted to encounter this emblem of our country and was able to catch a glimpse of it in the parking lot of the Spruce Bog trail in Algonquin Park.

The Story Behind the Species: The Canada Jay is a permanent resident of cold northern forests across North America (Cadman et. al. 1987). Algonquin Park is at the southern edge of their range in Ontario (Tozer 2012). Canada Jays are able to live and breed in their northern habitats because of their food-storing abilities. They are highly adaptable birds, feeding on a wide variety of food, obtained in a wide variety of ways. The Cornell All About Birds website sums it up like this: they will “snap up flying insects in the air, wade in shallow water to capture invertebrates and amphibians, kill small mammals, raid the nests of other birds” (https://www.allaboutbirds.org/guide/Canada_Jay/lifehistory). The food they gather in the summer is cached throughout their territories in preparation for the long winter. This food store allows them to start nesting as early as the end of February in Algonquin Park (Tozer 2012). They prefer to nest in spruce forests, and there is some evidence to suggest that the antibacterial properties of some conifers actually work to preserve the food the jays store in them (Tozer 2012).

Amazingly adaptable, clever and curious birds. I certainly support its status as unofficial National Bird of Canada.
