Our Magpie Neighbours

 

Magpie

With a loud voice, a long tail, and distinctive black and white markings, black-billed magpies are easy to spot. They are large birds (1.5-2 ft) living year-round in northwestern Canada and the United States. You won't find them along the west coast, but you will find them in the interior of British Columbia, Washington, Oregon, and California. 

Western Canada’s black-billed magpies are one of 17 different species of magpies around the world. They are almost identical to Eurasian magpies. However, magpies found in South and East Asia have vivid blue and green feathers. 
“In ancient Rome, the magpie was associated with magic and fortune telling, while in Scandinavia some witches rode magpies or turned into them. In Germany, the bird was considered a bird of the underworld and in Scotland it was said that magpies had a drop of the devil’s blood on their tongues. 

"Outside of Europe, the magpie has a much more positive image. In Native American legends, the magpie was considered a friend of hunter-gatherer tribes. In Korea, the magpie is thought to bring good news and in China it is a symbol of happiness, foretelling and good fortune.” [Horniman Museum & Gardens
Magpies are omnivorous, eating everything from insects, grains, and berries to small rodents, other birds’ eggs, and even young chicks (although eggs and chicks make up only a very small portion of their diet). They’ve adapted well to urban living, helping themselves to leftover food scraps. In rural areas, they pick the ticks from the backs of large mammals such as moose and deer. The ticks they don’t eat immediately are tucked away for future meals. “Most of the ticks, however, are cached alive and unharmed, and may live to reproduce later.” 

Magpies belong to the corvid family along with crows, ravens, and jays and are some of the most intelligent birds in the world. Magpies “can use tools, play games, work in teams, and even mimic human speech.” 
“One of the most notable Black-billed Magpie behaviors is the so-called ‘funeral’—when one magpie discovers a dead magpie, it begins calling loudly to attract other magpies. The gathering of raucously calling magpies (up to 40 birds have been observed) may last for 10 to 15 minutes before the birds disperse and fly off silently.” [All About Birds
Unlike other crows, magpies have a very long tail. In fact, it’s the same length as their body. Scientists aren’t sure why they have such a long tail, “but it may provide magpies with the ability to make swift turns while in the air. This would allow the birds to evade larger predators and make up for rather average flying abilities.” 


Magpies spend up to 40 days constructing large, solid domed nests roughly 30 inches high and 20 inches wide. They are so well constructed they can last for many years. “The male gathers sticks for the exterior. The female tends to the interior, forming a mud cup and lining it with grass.” 
Photographer Ron Dudley has been photographing one nest for over 7 years and shares some of his photographs. [Feathered Photography
Magpies are vocal, social birds. You’ll often find them sitting in groups calling loudly. A group of magpies is known as a parliament, possibly because they often gather in large groups to converse among themselves. They will also band together to chase away a raptor. In the spring, you may hear large groups of birds cawing loudly as younger birds try to chase away and take over the territory of more established pairs. 
“Magpies are very curious, just like their relatives, the jays and crows. They may sometimes pick up shiny things, but they don’t show any preference for shiny over dull. A magpie’s more likely to grab your sandwich than your silver.” [Audubon
Magpies often perch on poles or the tops of trees to provide a visual display of their territory. The males establish dominance over other males by stretching their neck and flashing their white eyelids. Magpies mate for life. The females initiate the mating display by begging for food from the male. They lay one brood of 1-9 eggs each year. The fledglings learn to fly when they are about a month old but may stay with their parents for a year before flying away to find a mate. Magpies are non-migratory and normally stay within a 10 km radius of where they were born.

Local News 
William Hale has opened a used electric vehicle dealership in Saskatoon. William says he’s driven an electric vehicle (EV), winter and summer, for 3 years and loves it. “The electrification of transportation is one of the principal pathways to a low carbon economy and I want to help with this transition in Saskatchewan,” he explains. The dealership offers a lower-priced entry into the EV market and an opportunity to ask questions and test drive the vehicles. They also sell and install EV chargers for home use. 

Green Shift Automotive in Regina sells a range of electric vehicles from bikes, scooters, and skateboards to hybrid and electric cars. 

Alberta Lake Management Society is offering a fall webinar series with applicability across Canada.

“Rebugging is looking at the ways, small and large, to nurture complex communities of these tiny, vital players in almost all the natural and not-so-natural places on earth. It means conserving them where they are managing to hang on, and restoring them where they are needed as part of a rewilding movement. And it means putting bugs back into our everyday lives, our homes and where we play and work.” [The Revelator, an excerpt from Rebugging the Planet: The Remarkable Things that Insects (and Other Invertebrates) Do – And Why We Need to Love Them More by Vicki Hird)

“Air conditioning is the most obvious immediate response to the dangerous warming of the planet. It’s also making it worse. … People are going to keep buying air conditioners … so we need to offer them better, safer, cleaner devices … We’re doing a disservice to our citizenry when we let them buy something that is so expensive to operate, and so polluting that cooling is actually adding to the warming of the planet.” [The Guardian
