It’s hard to believe that just a few weeks ago, March arrived liked a lion in a flurry of snow. There is no sign of snow now, and the first day of Spring was one for the record books. While the normal average temperature for this time of year is 4 degrees C, yesterday it soared to 25 degrees C (77F). Unheard of! But what a beautiful, perfect day.


We were just celebrating the arrival of the first Red-winged Blackbird a couple of weeks ago, but the birds have been showing up in a rush, Woodcocks and Song Sparrows, Chipping Sparrows, even a Turkey Vulture, compressing the usual spring arrival season into days instead of weeks.


The pussy willows are out and the first frog chorus has filled the evening air.


Here’s a little Johnny Jump-Up, or Viola, the first flower blooming in my garden.


The torrent of spring runoff has already slackened and the little river is flowing tranquilly along its course.


On the radio, the announcer was warning people that it was still a bit early to plant seeds! The traditional planting date here is May 24th. It’s a little unsettling, to be having May weather in March. But perhaps Mousie had the right idea. After months of wearing a winter blanket, she settled right into sunbathing and soaking up the heat. It was a wonderful gift of a day, from sunrise to peaceful sunset.

Northern Cardinal

This beautiful cardinal can be heard every morning now, singing out his song from a treetop perch. He’s been here all winter, but he has just started giving full voice to his chorus of “Birdie, Birdie, Birdie! Whit, whit, whit!” in the last week or so. What female could resist him?

It’s hard to believe that it was only last weekend that I spotted the first Red-winged Blackbird. Now they are everywhere, chucking and oak-a-leeing in the branches and foraging beneath the bird feeders. Over the course of the week, other migrants have joined them. There are quite a number of Common Grackles joining their numbers. Look at the beautiful iridescent colours on this fellow, helping himself to a seed at the feeder.


Common Grackle

As I was walking past a pine tree, I noticed a Brown-headed Cowbird keeping a cautious eye on me. There have been a few American Robins around for a few weeks, but now they are back in plentiful numbers. And this morning, I spotted a pair of Hooded Mergansers on the river. They skillfully avoided my attempts to capture them with my camera, taking off for a site farther upstream.

The birds are early, ready to put The Winter That Wasn’t behind them and move on to spring. This winter was the 3rd warmest on record here. Three of the warmest winters ever have been recorded in the last six years. What was additionally notable about this winter was the lack of precipitation. It was also the second driest winter on record.

How are these shifts in winter weather patterns affecting migrating birds?


Brown-headed Cowbird

A special report titled The Winter that Wasn’t: Bird Migration aired on CBC’s morning show The Current on March 7th. Biologist Allen Hurlbert from the University of North Carolina, B.C. biologist Dick Cannings and eBird editor Mike Burrell from Bancroft all addressed this question.

They note that the timing of migration is vitally important to the success of the upcoming breeding season. If a bird arrives back too early, he may encounter the bad weather and lack of food he flew south to avoid. If he arrives back too late, he may fail to find a good breeding territory and prospective mate.

One of the most important elements about timing is hitting the height of the insect season just right. Birds need a big supply of bugs to feed their demanding young. Without them, chicks may starve. If a warm spell disrupts normal insect patterns, causing bug populations to peak earlier, parent birds may not be able to adequately supply their young with food if they have started nesting according to their normal schedule.

We often have a poor appreciation of just how interconnected the natural world is. Failure or changes to one sector can have a ripple effect right through an ecosystem. Some bird species, such as Red-eyed Vireos seem to be adapting to changing weather patterns. Other species, such as Barn Swallows have been devastated. While Barn Swallows were once common birds, their numbers have plummeted by 75% over the last few decades.
