Rhodora
Right now, wildflowers are doing an amazing job of brightening up PEI’s spring landscape. Even bogs – habitats that go unnoticed most of the year – are putting on glorious displays of colourful Rhodora (Rhododendron canadense). Islanders are lucky enough to live in one of the few places in the world where we can enjoy Rhodora’s amazing spring show. While many of PEI’s native plants are also common in central and western Canada, or extend down the Atlantic coast of the US, R

Edible Cat-tail vs. Toxic Iris
PEI has so many wild foods on offer in May: fiddleheads and nettle greens, burdock and primrose roots, morel mushrooms and pheasant’s backs, and so much more! Cat-tails (Typha latifolia) are versatile and easy to use, but it’s good to know how to tell them from a toxic plant of the same wet habitats: Blue-flag Iris (Iris versicolor). Cat-tails and Iris aren’t hard to tell apart in summer and fall, but it can be easy to confuse them where they grow side-by-side in spring (ma

Geese and Mussels
The sound of Canada Geese is one of my favourite signs of spring – “goose music”, as Aldo Leopold called it. Their northerly migration is also marked by the return of feeding signs in PEI’s bays and estuaries, and some related behaviour that may surprise you! You may think of Canada Geese as herbivores that feed on aquatic vegetation and grasses in spring and summer, and the remnants of agricultural crops in fall. But, like many herbivores, Canada Geese are not strict veget

Marsh Marigold
As a botanist, I confess to teasing birders from time to time: groups of people flocking to the same spot to see an unusual species – really? But then spring rolls around and I eat my words as I make my annual pilgrimage to Miscouche to see Marsh Marigolds (Caltha palustris). Marsh Marigolds are neither unusual nor rare on PEI (and they aren’t Marigolds). This member of the Buttercup Family (Ranunculaceae) is found in wet, mucky soil, and so is more common in Prince and Kin

Duck Feet
PEI’s bird tracks come in five different forms. So far this winter we’ve looked at two: game bird (featuring Ruffed Grouse and Ring-necked Pheasant) and classic (aka ‘anisodactyl’, illustrated by a Bald Eagle). Today we look at the third type: webbed (aka ‘palmate’), with ducks as our example. The basic structure of webbed tracks resembles that of game birds, with three long toes pointing forward and one short toe pointing back. However, in this case, the three front toes a

Bald Eagle Tracks
Pop quiz: what’s the largest winter wildlife track you’ll find on PEI? Coyote is our largest animal, so that would be a reasonable – but wrong – guess. Snowshoe Hare’s hind feet are pretty big, but not the largest. The honour goes to an animal you may not have thought of: the Bald Eagle. When identifying bird tracks, toe arrangement is a helpful starting clue. Here we see three long toes pointing forward and one long toe pointing back, in what’s called the classic (aka ani

Woolly Alder Aphids
Welcome back to Ask a Naturalist, your own personal Google for information on all things natural on PEI. Today we have an insect that people often mistake for a fungus. Meet Woolly Alder Aphids ( Prociphilus tessellatus ). From a distance, Woolly Aphids do look like some sort of fluffy, fungal mould on the branch of a tree. But take a closer look and you’ll see that those fuzzy clusters are actually dozens – sometimes hundreds – of individual insects crowded together. The

Bog Birch
This fall, we’ve been exploring some of PEI’s least-common trees, including Balsam Poplar, Ironwood, and Jack Pine. Today it’s one many people haven’t even heard of: Bog Birch ( Betula pumila ). We often think of Birch as among the majestic trees of PEI’s early forests. Nineteenth century writers told of Yellow Birch ( Betula alleghaniensis ) three to four feet in diameter, and it was said that Mi’kmaq people were able to make a six-person canoe from the bark of a single Wh
