A medium-sized songbird found in North American tallgrass prairie, other open meadows and hay fields, male Bobolinks are black with a white back and yellow collar during their summer breeding season. (Some have described their striking look as wearing a tuxedo backwards.)

Bobolink molt twice a year, completely changing all their feathers on both the breeding and wintering grounds. When the male grows new feathers on the wintering grounds they all have yellowish tips, so he still looks like a non-breeding bird. Eventually the pale tips wear off to reveal his striking black-and-white breeding colors.

By late summer, male bobolink will lose much of this breeding plumage and more closely resemble the female’s tan colour with black stripes.

Bobolinks are related to blackbirds, which are often polygynous, meaning that males may have several mates per breeding season. Bobolinks are polygynous, too—but they’re also often polyandrous: each clutch of eggs laid by a single female may have multiple fathers.

Because Bobolinks spend much of their time out of sight on the ground feeding on insects and seeds, they may seem to appear out of nowhere, spotted flying in the sky or over the tops of vegetation singing a bubbling musical song.

The Bobolink breeds across North America. Here, in Ontario, it is widely distributed throughout most of the province south of the boreal forest, although it may be found in the north where suitable habitat exists. The Bobolink is considered a “wide ranging species” and in fact, the Bobolink is one of the world’s most impressive songbird migrants, travelling approximately 20,000 km to and from South America. Throughout its lifetime, it may travel the equivalent of 4 or 5 times around the circumference of the earth.

Bobolinks often build their small nests on the ground in dense grasses. Both parents usually tend to their young, sometimes with a third Bobolink helping. The species name of the Bobolink, oryzivorus means “rice eating” and refers to this bird’s appetite for rice and other grains, especially during migration and in winter.

March 20, 2014 has been designated World Frog Day (also known as Save the Frogs Day) to coincide with the first day of spring. (The release, a day later, of Muppets Most Wanted, starring perhaps the world’s most famous frog, Kermit, is just a happy coincidence.)

First celebrated in 2009, World Frog Day has become the world’s largest day of amphibian education and conservation action. Many are using this designated day to focus on the worldwide decline in the amphibian population in locations across the globe. Today, one-third of the world’s amphibian species are threatened with extinction. Since 1979, 200 frog species have disappeared completely. This decline in population has been attributed to disease, habitat destruction and modification, climate change, pollution and pesticide use.

In 2013, over 270 events were held as part of Save the Frogs Day in 30 countries around the world.

There is evidence that the frog has been around for 200 million years. Today, there are approximately 5,000 species of frogs in the world from the Wood Frog that freezes and then thaws every winter to the Australian Rocket Frog who can leap over 50 times its own body length.  Frogs of one species or another can be found on every continent, with the exception of Antarctica.

How the Frog Helps You

• Tadpoles keep waterways clean by feeding on algae.
• Adult frogs eat large quantities of insects, including those such as mosquitoes that can transmit fatal illnesses to humans.
• Frogs produce a wide array of skin secretions, many of which have the potential to improve human health through their use as pharmaceuticals. (Approximately 10% of Nobel Prizes is Physiology and Medicines have resulted from investigations that used frogs.)

This Week’s Endangered Species is the Barn Swallow (Hirundo Rustico). Although of African Origin, the Barn Swallow has the largest range of any swallow, found in Europe, Asia and Africa as well as the Americas. 

The Barn Swallow is distinguished from other swallows by having a wider breast band and less white in their tails. They also fly much lower than most other swallows.

They associate closely with humans, nesting in buildings and other structures.

Residing in mature deciduous forests and streamsides, the Acadian Flycatcher has an olive-green crown, back and tail with a pale whitish throat and breast. The Acadian’s most prominent feature of this bird is the bold white ring around the eye, and two whitish horizontal bars on the wing. The beak is short but wide-based, allowing a big opening for snatching insects out of the air.

Above and beyond its physical features, the Acadian Flycatcher is best distinguished from other Flycatchers by its explosive song often interpreted as “peet-sah”, with a strong emphasis on the first syllable.

Did You Know?

March 17-23, 2014 is Canada Water Week, a celebration of water from coast-to-coast. Canada Water Week is held annually in the third week of March so as to coincide with World Water Day, which takes place on March 22.

This year’s campaign is Watersheds 101. A watershed is defined by Canadian Geographic as “an area of land where all the surface water drains into the same place, whether is it a creek, a stream, a river or an ocean.”

Canada has five main watersheds: the Atlantic, the Hudson Bay, the Arctic, the Pacific and the Gulf of Mexico. There are, however, hundreds of smaller sub-watersheds throughout Canada.

Our area is located in the Thames River watershed, which flows downstream into Lake St. Clair. Nestled in the agricultural heartland of Southwestern Ontario in close proximity to Lakes Huron, St. Clair and Erie.  The second largest watershed in southwestern Ontario, the Thames River is 273 km long and drains 5,825 square kilometres of land. The Thames is accessible to a half million people residing in its watershed.
