Why spring is so important to the natural world
Throughout the last month, we have been watching Canada's spring unfold across the country and you have been sharing your spring with us using #HelloSpringCBC. Here are just some of the things our wildlife has been up to this spring!
This is lekking, and for grouse, it is the only way to find a mate. If you are a sharp-tailed grouse you have to show off by waving that fluffy white tail, flashing those bright purple air sacs whilst shuffle dancing with your wings outstretched!
Lekking takes place on the open grasslands where hundreds of grouse gather, performing the same moves repeatedly. The females watch from the sidelines, picking out a worthy mate. This strategy may seem like a lot of effort, but it is highly effective. The healthier males lek the longest and go on to mate, passing on the healthiest genes to the next generation.
While you might need to go to a specific place to see these displays; another mating ritual is happening right outside your door and you might be noticing it more this year, it is birdsong. Bird songs can be a wonderful sign of spring, but in the bird world, it is serious stuff.
So, what are they doing when they sing? Like the grouse, they are showing off! Whether it is a robin, warbler or a yellow-breasted chat; they are singing for as long as possible to show the females how fit they are, inviting them to their territory and warning rival males to back off!

Travelling home
The climate in Canada means that many species must move south to avoid our long and cold winter. But as spring brings warmer, milder weather, these species return home; sometimes travelling thousands of kilometres to get here!
Warblers are a famous example of migratory birds that you may see near you. This beautiful Cape May warbler has travelled from southern Florida and the Caribbean to breed in Canada's eastern and boreal forests.
Cliff swallows are another amazing migratory species, they can be seen in almost every province and territory, returning to nest in large groups and building intricate mud nests that cling to vertical walls.
Waking up from hibernation
Some of Canada's wildlife spends the winter sound asleep! In spring it is time to wake up and emerge from their hibernation!
Painted turtles are a fantastic example of this! Most adult painted turtles will spend the winter hibernating in mud at the bottom of ponds and lakes. As the temperature warms up and the ice begins to melt, painted turtles leave the mud and start their courtship, you can often see them basking on logs like this one!
Many people across the country have been seeing black bears as they emerge from their dens. Black bears can lose 30 per cent of their body weight during the winter, so spring is an important time to gain weight. Female black bears are also raising their cubs, who were born during the winter months.
Flowering
Canada is home to approximately 4,000 flowering plants; our vast landscapes, diverse regions and ecosystems provide habitat for a huge variety of species. The wide array of flowering plants mean that Canadians can enjoy different species flowering throughout the spring season!
Wild/Prairie crocus is one of the earliest wildflowers to poke up out of the frozen ground. This wonderful photo was taken in Whitehorse, Yukon by Colleen Parker where these crocuses flower as early as April.
Camas is a flowering plant found throughout Vancouver Island and the Gulf Islands in B.C. It grows within one of the endangered ecosystems in Canada, Garry Oak meadow.
Having cute babies
One of the most exciting aspects of spring is all the adorable animal babies! These youngsters have a lot to learn in a small time frame; their spring is packed full of new experiences and adventures, which is not only fascinating to watch but also so much fun!
This baby great horned owl is still looking a little fluffy! Young owls are almost fully feathered and able to manage short flights at around eight weeks old. However, they will remain largely dependent on their parents for food during most of the summer.
