Red Maple Flowers
It’s that time of year when many people are anticipating the first flowers of spring, without realizing that some are already here! We’ve looked at two of my favorite precocious plants – Willow and Beaked Hazelnut – but I also have a soft spot for Red Maple ( Acer rubrum ), flowering now. When we think of flowering trees, it’s often Apples, Cherries, and Serviceberries that come to mind. These showy species follow the usual order of things: leaf out first, then flower. But

Hazelnut Flowers
Some of PEI’s early spring wildflowers are showy, in-your-face sorts. Others are tiny, delicate, and go unnoticed to all except to those specifically looking for them. Today’s plant is in the latter category, and one of my favourites: Beaked Hazelnut ( Corylus cornuta ), flowering now. Hazelnut is a common, native understorey shrub found in mixed forests and along streams and trails across the Island. It stands out in the landscape this time of year, with finger-like male c

Black Knot Fungus
This is a great time of year to spot a PEI fungust that's best known as a disease of Cherry trees: Black Knot ( Apiosporina morbosa ). Black Knot fungus forms distinctive, black galls on stems and branches of our native Pin Cherry and Chokecherry, as well as ornamental Cherries and Plums. While it’s unattractive, reduces fruit production, and may kill the infected branch, Black Knot doesn’t usually kill the entire tree unless the infection is very severe. Within those black

Pussy Willows
One of PEI’s first botanical signs of spring are Pussy Willows ( Salix spp.). We have more than a dozen different Willows on the Island, but only one – Salix discolor – officially has the common name ‘Pussy Willow’. Willows are notoriously difficult to tell apart, but don’t worry: all our species are commonly called Pussy Willows this time of year so, right now, you can’t go wrong! Those soft, fuzzy balls are the male flower buds, called catkins. (Female catkins are sim

Flying Squirrels
One of my favourite PEI animals is seldom seen despite being fairly common: the Northern Flying Squirrel ( Glaucomys sabrinus ), shown here in a photo by Ron Serres (used with permission). Flying Squirrels are beautiful, large-eyed, soft-furred animals, with a flap of skin (called a ‘patagium’) running from wrists to ankles on each side. That flap allows them to glide 50 metres or more between trees in the forest and has been copied by the wingsuits used by some BASE jumpe

Lung Lichen
You may think there’s no old growth forest or wilderness on PEI, but that’s not true. We have amazing ancient and wild spaces if you know where to look and can recognize the signs. Lung Lichen ( Lobaria pulmonaria ) is one of those signs. A lichen is a unique creature: usually, it’s a combination of a fungus and an alga or cyanobacterium functioning as one organism. But Lung Lichen is one PEI’s few tripartite lichens: it includes a fungus, a green alga, and a cyanobacter

Pileated Woodpeckers
Some PEI wildlife signs are subtle, while others are hard to miss! These are the unmistakable holes of a Pileated Woodpecker. Pileated Woodpeckers are roughly crow-sized birds, with black bodies, white stripes down their necks, white patches on their wings (visible in flight), and a dramatic red crest on their heads. If you can imagine Woody Woodpecker, you’ll be in the ballpark: the Pileated Woodpecker is said to have been the inspiration for that cartoon character. Th

Cavity Trees
We’ve looked at needle-leaved and broadleaved trees this winter but standing and fallen dead trees make enormous contributions to PEI’s forests, too! Trees die naturally from a variety of causes: old age, disease, insects, fire, weather damage, or environmental stress, among others. The death of a tree is part of the life of a forest and is necessary for the survival of everything from plants, lichens, and fungi to insects, birds, and mammals. Insects such as Bark Beet

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

Stoneflies
If you think the best thing about a PEI winter is the absence of insects, I have bad news for you: this is peak season for some of our invertebrates! Carla McKie recently sent me this photo of one the creepie-crawlies on the snow in Rock Barra, wondering what they might be. They are Winter Stoneflies, also known as Willowflies ( Taeniopterygidae Family). At first glance, you might think this is an Earwig out for a mid-winter stroll. Like Earwigs, Winter Stoneflies have six

Eyeshine
Tracks and scat may be the most common signs of PEI wildlife, but they are not the only ones. Other examples include dens, nests, cavities, caches, browse, and this very cool adaptation: eyeshine. Not all animals have eyeshine, but those that do have a special membrane called the tapetum lucidum (Latin for bright tapestry) behind the retina – the light-sensitive part of the eye. Light passes through the retina and is reflected off the tapetum lucidum back to the light sourc

Larch Adaptations
Last month, I posted about the advantages and disadvantages of multi-year needles versus annual broad leaves on trees (You can read about that here: https://www.pei-untamed.com/post/conifer-adaptations ). Some of you asked about Eastern Larch, a tree with a foot in each world. Let’s take a look! Keeping needles all winter does have a price: it allows snow to build up on the tree, placing tremendous weight on its branches. This can cause branches to break, or entire trees to

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

Blue Tree Resin
Welcome back to Ask a Naturalist, your own personal Google for information on all things natural on PEI. Jeff Matheson sent me this wonderful photo of blue resin on the side of a spruce tree and was curious about the unusual colour. Let’s take a look! First, it’s useful to know the difference between sap and resin (sometimes called pitch). All trees have sap, and it’s analogous to blood in animals: it carries water, sugar, nutrients, minerals, and hormones throughout the tr

Grouse vs. Pheasant Tracks
Birds may not be the first animals that come to mind when you think winter wildlife tracks, but some of our avian neighbours spend more time walking than flying. Two good examples are Ruffed Grouse and Ring-necked Pheasant. When identifying bird tracks, toe arrangement is a helpful place to start. Here we see three long toes pointing forward and one short toe pointing back in what’s called the Game Bird arrangement. Only four PEI bird species sport feet like these, and so r

Conifer Adaptations
Snow on spruce trees is a hallmark of the Canadian winter. While most PEI plants lose their leaves or disappear altogether as temperatures drop, you may not have thought about how and why conifers take a different approach. Today, we take a look! Broad-leaved trees like Maple, Beech, and Birch produce big leaves with huge surface areas that are very efficient at catching sunlight and turning it into food for the tree. Even if those leaves didn’t freeze, they lose water an

Feline Track Refresher
Whether it’s the potential for Bobcats here on PEI or reports of Eastern Cougar on the mainland, wild cats have a mystique that makes many of us want a track to be Feline. This, coupled with how feline some canine tracks look, means Dog tracks are sometimes mistaken for Cat even by experienced trackers. Let’s look at the differences. As we saw earlier this month, canine tracks have an X-shaped negative space – that area between the pads of the foot; I’ve included my earlie

Hoar Frost vs. Rime Ice
Few PEI scenes are more beautiful than frosty winter mornings like the one we had last week. Under certain conditions, ice crystals coat trees, twigs, and fence lines, turning the landscape into something magical. We call this ‘hoar frost’, but there are actually two very different types of ice that cause this phenomenon. Let’s take a look! ‘Hoar’ is an old word for feathery white, like a beard. It’s an apt description for the delicate, feathery ice crystals that form true

Snowshoe Hare Tracks & Scat
So far this winter, I’ve had more questions about this type of track than all others combined. It seems everyone is curious about Snowshoe Hares! I get it: Snowshoe Hare tracks look like they were made by Muppets and they’re everywhere . It’s been like this for the past couple of years, and I do think 2022’s Hurricane Fiona played a role. Leaning or downed hardwoods put tasty branches and buds within reach, and fallen conifers provide useful cover from predators. The dis

Sunburst Lichen
The Island’s winter landscape is mostly monochrome, making the occasional burst of colour all that more beautiful. One of my favourite bright spots is the aptly-named Maritime Sunburst Lichen ( Xanthoria parietina ). Lichens are interesting in many ways, including how they survive our coldest months. Most living things go to great lengths to protect themselves from drying out or freezing: two major (and usually lethal) side effects of winter. That’s why PEI’s trees, plants, f
