Exploring the characteristics of twigs and buds is a great winter pastime After the dramatic reds, oranges and yellows of fall leaves, it’s easy to think that the seemingly barren trees of winter offer little of interest. Fortunately, for those of us who enjoy winter botanizing, the trees Read more…
The annual Christmas Bird Count reveals the ups and downs of bird populations – and always some surprises. Between mid-December and early January, birders in more than 2,500 localities across North, Central and South America take a break from the holiday festivities to spend a day outside, identifying and counting Read more…
2017 saw dire environmental stories grab centre stage but all was not doom and gloom As we shiver into 2018, I would like to take a moment to look back at 2017 and revisit some of the top environmental and climate change stories. The past 12 months represent a stark Read more…
The winter solstice is a time of wonder and the assurance of spring’s return Today marks the winter solstice and the first official day of winter. It is a time of contemplation and reverence, not only in its spiritual dimensions but also as a reflection of the human capacity for Read more…
Seeds, bee houses and more: Tips for what to put under the Christmas tree If you have someone on your Christmas list who would rather spend time in the garden than head to the mall, who prefers nature books to the latest novel, and who wants to support conservation and Read more…
The holiday season is the perfect time to get to know the conifers With practice, it’s possible to identify many plants and animals by size and shape alone. Any two European starlings will always look plump, have a relatively long, straight bill and sport a short, square tail. In flight, Read more…
Expect a lot of snow and a ‘classic Canadian winter’ In my fall nature almanac, I had the temerity to predict that the sunshine and cool temperatures of early September would lead to extraordinary leaf colour. Well, I sure got that wrong. In fact, this fall’s colour show was one Read more…
The Boundary Bay area is one of Vancouver’s premier wildlife destinations As we walked slowly along log-strewn Blackie Spit, flocks of shorebirds flew low over the waves, their white feathers shimmering in the early morning sun. Ducks and cormorants streamed overhead, while loons and grebes dove in the waters offshore. Read more…
Late fall is a great time to get to know these enigmatic structures I’ve always loved November. Maybe it’s the change of pace and the sense of nature slowing down. Yet, we do notice changes. As deciduous trees shed their leaves, our eyes are drawn to the conifers like at Read more…
Much remains to be explained about these familiar birds When a species is as common as the blue jay, we tend to take it for granted. We are often dulled into thinking that there’s little new to be discovered about its behaviour. Well, think again. From their aggressive mobbing behaviour Read more…
Bird numbers and diversity at feeders at feeders depends on wild seed abundance If you’ve been paying attention to coniferous trees this fall, you’ve probably noticed the abundance of cones on many species. Cedars and spruce, for example, have produced an especially heavy crop. The quantity of seed on sugar Read more…
Everything from climate change to invasive species are threatening our lakes, rivers and fish populations Slowly but steadily, the lakes and rivers of the Kawarthas are changing. The abundance and variety of fish populations are undergoing a transformation that could make them unrecognizable in a few short decades. This week, Read more…
Threats loom but fish populations in the Kawarthas are still doing well One of my most formative nature experiences as a boy was fishing with my grandfather at the family cottage on Clear Lake. The excitement of hooking into a large bass or walleye was unforgettable. Even at that time, Read more…
Myriad threats and declines evident in the Kawarthas, too Living in a country as big and relatively unpopulated as Canada, it might come as a surprise that much of our wildlife is in serious decline. This was made abundantly clear last week when World Wildlife Fund Canada (WWF) released its Read more…
For anyone paying attention, the biggest story of the past summer has been the fury unleashed by planet Earth as a result of climate change. As Clive Hunter, an Australian public intellectual, said on CBC Radio’s Ideas recently, “What we’re now confronted with is a wakened, angry, raging beast.” The Read more…
First, a disclaimer. I am far from being an expert on the edible wild. That being said, this is an area I want to explore in coming years, partly because it has great potential in getting more people interested in nature. This is especially true right now, given the popularity Read more…
In case you might be looking for some new reading material this summer, I would like to suggest some of my favourite books from the past few years. If there is one theme they have in common, it’s that science, nature history, intellectual satisfaction and wonder are all part of Read more…
As a tide of green leaves transforms the landscape each spring, a near limitless smorgasbord of food is offered up to leaf munchers of all kinds. Among the most noticeable of these are tent caterpillars. Eastern tent caterpillars – the ones that make an actual tent – were especially abundant Read more…
Now that summer has officially arrived, I would like to look ahead at some of the events in nature that we can expect over the next three months. The actual timing of events is directly affected by temperature, rainfall, and day length. While these environmental factors obviously change throughout the Read more…
Every culture has its own origin story. They may be short anecdotes or elaborate narratives that help explain the mysteries of our existence. “Big History” is an origin story unlike any other. Instead of being rooted in a specific culture or geography, it presents a science-based perspective and is therefore Read more…
When it comes to seeing new species of plants and animals, a certain amount of effort is usually required. This might mean traveling to new locations and walking considerable distances. There is, however, a way to enjoy nature’s diversity that can appeal to even the most sedentary among us. Welcome Read more…
It was the Kirtland’s warbler that made our morning. In the red cedar ten metres off the trail, the small grey and yellow bird was all but invisible. Only when it flitted from one branch to another was there any chance of seeing it – and it didn’t flit often. Read more…
My passion for nature began with turtles. Catching these wary reptiles was one of my favourite pastimes as a child. I was especially proud whenever I managed to bring home a snapping turtle, keep it for a day or two and show it off to my friends and family. I Read more…
One of my greatest pleasures in May is the welcome sight and sound of songbirds returning right on cue from their southern wintering grounds. I was therefore delighted to hear a northern waterthrush belting out its emphatic double-note song at the start of the de Pencier Trail at the Trent Read more…
Take a moment to envision the most meaningful place of your childhood. There’s a good chance that it was somewhere outdoors. Ours, however, may be the last generation to remember what it’s like to deeply connect with nature. Why? Because children around the world today spend as much as 90% Read more…
One of the greatest gifts you can give a child is a sense of wonder in the natural world and how everything in nature can be explained by science and critical thinking. And nowhere is there a better example of the power of critical thinking than when it comes to Read more…
Kids make great amateur scientists. They love to ask “why” questions. “Why is the monarch butterfly so colourful? Why does it start life as a caterpillar? Why does it migrate? Thanks to Charles Darwin, we now understand that questions such as these are entitled to an evidence-based answer – and Read more…
When I used to hear the words ‘brook trout’, the image that came to mind was a pristine lake in Algonquin Park. Well, that image has changed. What I now see is a tiny stream running along Rye Street in this busy commercial and industrial sector of southwest Peterborough. As Read more…
As we turn the corner into spring, let’s pause a moment to reflect back on the winter that’s been. For many people, the temperate weather was a blessing, with only moderate snowfall and temperatures well above average. Yes, the abnormally mild winter did make life easier for most of us. Read more…
Stretching from Georgian Bay to Kingston, along the interface of the St. Lawrence Lowlands and the Canadian Shield, is a unique ecoregion, now known as The Land Between. It is home to loons, bears, moose, deer and more hummingbirds, at risk reptiles and habitat types than anywhere in the province. At Read more…
