July / August 2018
It’s summer! The summer solstice (our longest hours of daylight) was in June, so that means the days are get- ting shorter. But don’t panic, there is still lots of warm, summer weather ahead. You may have already noticed that it is getting darker earlier each day. Perfect timing to take in the Perseids meteorite shower without having to stay up late into the night. The Perseids is one of my favourite meteorite showers. We actually get 10 to 12 good annual meteorite showers each year. The Perseids in August and the Geminids in December are some of the best. I like the Perseids because the weather is usually perfect for spreading out a blanket and lying on your back in the dark. This year the Perseids will take place from August 11 to 13.
Meteorite showers get their names from the constellation from which they appear to be coming. But the shoot- ing stars or meteorites do not originate in those constellations. The Perseids meteors originate from the Comet Swift-Tuttle which orbits our Sun every 130 years or so. (Earthlings will get a chance to see it again when it passes 23 million kilometers from Earth in 2126). Each year the Earth’s orbit passes through the dust trail of the comet. Most of the dust particles are only about the size of a grain of sand, but they are spectacular when they enter Earth’s atmosphere. If you rub your hands together quickly you create friction, and your hands feel the heat caused by the friction. According to meteor experts, the dust particles of Comet Swift-Tuttle are moving at 59 km per second. At that speed the friction caused when the dust particles rub up against our atmosphere is incredible. It causes the dust particles (and the air around them) to become very, very hot, creating a brilliant streak of light that we call a shooting star or meteorite.
To best place to observe a meteorite shower is someplace dark. Get away from the lights of the city if you can. Places like Cranberry Flats or the Northeast Swale are good places as you have a wide open view of the night sky. (Cypress Hills Provincial Park and Grasslands National Park in southern Saskatchewan are designated Dark Sky Preserves, so those places will be ideal). This year should be an especially good one for the Perseids meteor shower as the moon will just be a small crescent, making the sky much darker than a full moon. Find a comfortable place to sit or lay down and watch the night sky. It will actually take your eyes a while (15 minutes or longer) to become adjusted to the night sky. But once you’re comfortable, sit or lay back and enjoy the show. The meteor experts say the Earth will pass through Comet Swift-Tuttle’s dust trail from August 11 to 13, with the Earth passing through the dustiest part of the comet trail on August 12. I sure hope it is cloudless night on August 12. (Graphic from www.skyandtelescope.com)
Butterflies at the Northeast Swale
The Young Naturalists is about getting kids interested in nature. It’s not that hard: kids love nature. In July we are looking at butterflies (and other insects) and the Northeast Swale. Here is a quick beginners’ look at some of the more common butterflies we might expect to encounter.
Butterflies and moths belong to the group of insects called the lepidopterans. It is a special word used by scientists that means ‘scaly wings’. Both butterflies and moths have scales on their wings. (A butterfly is actually a type of moth.
You can tell the difference by shape of their antennae). The scales are quite delicate and loosely attached, which is why we need to know how handle
butterflies without damaging their scales. You can check out the scales for yourself. Carefully look for dead butterflies or moths on the front grill of parked cars or around an unplugged ‘bug zapper’.
If you rub their wings the scales will come off on your fingers in the form of a dust.
Butterfly wings are covered in thousands of these dusty scales. The scales help the butterfly warm up its body by catching heat from the sun. The scales are also what gives the butterfly its beautiful colours. Take a close look at the scales. Some are colourful, some are transparent, and some are iridescent giving off shiny colours when the light hits them.
If you are walking at the Northeast Swale or other natural area around Saskatoon you will see butterflies fluttering by. Here is quick looks at some of the more common ones.
Common Wood Nymphs are probably the most common brown coloured butterfly at the Northeast Swale in July. These are brownish-coloured butterflies with large eye spots on their wings. You can tell the boys from the girls because the girls are bigger and have bigger eye spots. If we do catch a male, be sure to check out its upperwing for a purple iridescence. (Photo from www.bugguide.net)
Yellow Butterflies will most likely belong to the group of butterflies known as ‘Sulphurs’. The most common Sulphur at the Northeast Swale is the Clouded Sulphur. The upper- wing will give you a clue as to who is a boy and who is a girl. The beautiful yellow upper- wing has a thin black border. On the males the black border is solid, on the females there will be yellow spots on the border. (Photo from www.butterfliesandmoths.org)
The White Butterflies we encounter will most likely be Cabbage Butterfly (or Cabbage White). These are a European species that was accidentally introduced into North America over 150 years ago. Today, they can be almost everywhere. Gardeners don’t like them as their caterpillars can damage garden plants. Up close, these are beautiful little butterflies with a greenish tinge to the underwing. (Photo from www.butterfliesandmoths.org)
The small blue butterflies will belong to the group of butterflies appropriately known as ‘Blues’ and they have great names like Spring Azure, Silvery Blue, Greenish Blue, Arctic Blue, and Melissa Blue. The Spring Azure is the most common Blue on the Northeast Swale, as they are fond of Saskatoon and Chokecherry blooms. (Photo from www.butterfliesandmoths.org)
There are always surprises when looking for butterflies. We will be keeping our eyes open for the butterfly with the cool sounding name: Great Spangled Fritillary. Their underwings are fairly dull, but when flying they are a beautiful orange and black. (Photo from www.butterfliesandmoths.org)
There are a lot more butterflies to be found. Butterflies love the nectar from flowers. It makes them important pollinators for the wildflowers growing in our natural areas. As you notice the butterflies, take note of which flowers each type seems to prefer.
Young Naturalists Report
Once June rolls around the Young Naturalists take on their premier environmental education project: the Bluebird Trail. Saskatoon’s Bluebird Trail was started in 1969 by the Young Naturalists (called the Junior Naturalists back then) led by Mary Houston. At the time, bluebirds were a species in decline. This was mainly to due habitat destruction and competition for nesting sites by introduced species like the European House Sparrow and the European Starling. Bluebirds are cavity nesters, which means they nest inside cavities in old trees. Usually an old woodpecker’s nest. One of the solutions to help bluebirds across North America was to create artificial tree cavities; better known as a birdhouse. (Although Bluebird Trail people prefer the term ‘nestbox’).

There are Bluebird Trails all over North America. Ours is part of a trail running from Edmonton to Winnipeg. (Our section of the trail runs from Langham to Hanely). Each year volunteers check the nestboxes and record the species of bird and the number of eggs or young bird in the box. Mary Houston was interested in more than just the productivity of the birds (how many eggs and babies), she wanted to know things like where bluebirds went for the winter, how long do they live, and do they return to the same nest each year? To understand this you need to track the bird with a numbered leg band. Mary obtained a scientific permit from Environment Canada’s Bird Banding Office to band birds. This made Saskatoon’s Bluebird Trail something special, as the Young Naturalists not only monitored the productivity of the birds, we
also studied their survivorship and other factors with leg bands. Forty nine years later and the Young Naturalists are still banding birds on our bluebird trail.
This was very busy June checking all the nest boxes on the bluebird trail. Most were occupied by Tree Swallows and quite a few had House Wrens (and one chickadee family!). But the exciting news was the Mountain Bluebirds. We knew it was going to be a good year when the first nestbox we checked had bluebirds! This year we are happy to report we managed to band 36 juvenile Mountain Bluebirds – up from 20 last year. We wish all our birds a safe journey south and we hope to see many of them return to their nestboxes again next year for our 50th year of banding on the bluebird trail.
