Canada’s Golden Eagle And The Acela-1 Express Train

Leave a comment

The Golden Eagle is one of the best known and largest birds of prey in North America. The adult birds are dark brown in colour with golden-brown feathers on the back of their head, neck and upper wings.

 

Golden Eagles use their strength, agility and powerful talons to snatch up prey including mice, rabbits, squirrels and even fox and young deer.

They are very swift and can reach speeds over 240 km per hour while diving in on their target. <240 km/h is about 150 mp/h- the top cruising speed of the American Commuter Acela- 1 express train. Watch the following video clip and note at the 1m 8s mark as  the Acela passes the station at about the same speed that the Golden Eagle achieves in a dive. Wow!

Golden eagles usually mate for life.

They build huge nests in high places including cliffs, trees, or even telephone poles and may return to this same nest for several breeding years.

The Golden Eagle is listed under Ontario’s Endangered Species Act, 2007, which protects it from being killed, harmed, possessed, collected or sold, and protects the habitat from damage or destruction. For the Silo, Dixie Greenwood.

Largest Moth In North America

Leave a comment

Emerging soon- the Cecropia caterpillar takes two months to develop before forming their cocoon which has to last an entire winter.

The Cecropia Moth is North America’s largest native moth and is a member of the giant silk moth family. It can be found in all Canadian provinces except BC and Newfoundland. The wings are reddish brown, and crossed in the middle with a white band. In the middle of each wing there is a crescent-shaped white spot bordered with red. The moths can have a wingspan up to 160 mm (6 inches!)

Females have a large abdomen for egg production, and males have hugely feathered antennae to detect the pheromones that the female emits. The male is capable of smelling the female from over a kilometer away.

Once mated, the female will lay her eggs near host trees. Typically they choose maple trees for their host, but they can also be found on other trees like Birch, Alder, Apples and Willow. The eggs will hatch in about 2 weeks and the newly born caterpillar will eat its eggshell.

The Cecropia larva (caterpillar) has two rows of blue tubercles along each side, two rows of yellow tubercles down its back, and two pairs of large red tubercles on the thorax. It takes the caterpillar approximately 2 months to reach full size at which time they will find a dark secluded place to attach themselves to a branch or stick and form their cocoon. This cocoon will overwinter and the adults will emerge the following spring.

Adult Cecropia moths do not have mouth parts and thus are unable to eat. As a result, the lifespan for an adult is generally only about 7-10 days.  For the Silo, Dixie Greenwood.

Crickets And Grasshoppers Relaxing Sounds For Your Mind

Leave a comment

If you didn’t know already, crickets and grasshoppers are not the same insect- though they do share a distant common ancestor from somewhere back in time.

How can you tell them apart?

For one thing, grasshoppers have short antennae whereas crickets have long antennae. Considering that crickets are active at night, in the dark- it makes sense for them to have “supercharged” antennae.

Oh but the sound.

It’s amazing to know that together and in unison, thousands upon thousands of orthopterans (the common order that is shared by crickets and katydids,  grasshoppers and locusts) can create a huge amount of sound from nothing more than, in the case of grasshoppers: rubbing their hind legs against their forelimbs or in the case of crickets: rubbing their fore wings together.  Judging by the number of nature recordings ready for streaming,  many of us are enjoying these sounds as a soothing treatment to help us unwind, relax and fall asleep.  For the Silo, Jarrod Barker.

From the nature recordist NeCubFlyer:

“I’ve been recording high quality nature sounds for over 26 years for my own personal use. When I first started, nature recordings didn’t exist and when these types of recordings finally hit the market, they were so overly compressed & attenuated it didn’t even remotely sound natural!

Throughout some recordings you may find sounds that are man made.

All of my recordings are captured in nature as it happens. None of my recordings have been “Computer Generated” or are short segments looped together. I have traveled to some of the most remote areas of the US to capture my nature sounds only to find jets flying overhead or a train off in the distance blowing its horn. It is virtually impossible to capture a clean recording without the “Hand of Man” being heard. To remove these sounds would take some serious computer manipulation and destroy the integrally of the recording! Being a purest… what you hear is what you get… just like the real world.

If you enjoy these soothing sounds, please   visit my site  and help show your support…I hope you enjoy this beautiful recording as much as I have!!!”

The Canada Goose

Leave a comment

CANADA GOOSE aka Branta canadensis

The Giant Canada Goose is one of the most common and widespread species of goose in North America. It is most easily identified by its brownish-grey body, long black neck with a black head, and white patches on the face.

Canada Geese live around ponds, rivers and lake shores, and have become quite a common sight in parks. It’s hard to believe that they were nearly extinct in the 1960’s!

Geese feed mostly on land and frequently spend 12 hours a day or more feeding. Their diet consists of a variety of grasses, aquatic vegetation, and various grains.

Canada geese find mates during their second year and once paired, the geese remain together for life. Females usually return to the same nesting area each year.

Although an increasing number of Canada Geese are choosing to winter in Canada, especially in urban areas, the majority fly south to the United States and even Mexico

The spectacle of Canada Geese migrating in long, honking, irregular “V” formations across spring or autumn skies is one of the most dramatic indications of the change of seasons in Canada. For the Silo, Dixie Greenwood.

Places To Pick Provincial White Trillium In Ontario

Leave a comment

Trillium photo: D. Greenwood

The white trillium is a spring wildflower with 3 distinct leaves and petals.  It has been the provincial flower of Ontario since 1937 and is also the logo of the Ontario Government.  It’s white flower is seen as a symbol of peace and hope.

While it is a popular belief that it’s illegal to pick the White Trillium in Ontario, in reality they are only protected in provincial parks and land owned by conservation authorities.  However, if the leaves as well as the flower are picked, the plant could die as it no longer has any means to produce the energy it needs to take it through the winter into another spring.

Sometimes mutant plants with green striped petals are found in White Trilliums.  These plants are diseased — infected with parasitic mycoplasmas that cause the greening. Over time, the mycoplasmas will cause deformity in the petals and eventually the death of the plant. For the Silo, Dixie Greenwood.

Bird Eats Fruit To Get Drunk

Leave a comment

The waxwing-

Cedar Waxwings are sleek, masked birds found year round in our area with unusual red, waxy deposits at the tips of their secondary feathers. They are cinnamon-colored, with grayish wings and tails and yellow terminal tail-bands. They have distinctive crested heads, black throats, and black masks lined with white.
The Cedar Waxwing is one of the few North American birds that specialize in eating fruit. It can survive on fruit alone for several months. They also eat flying insects and can often by seen fly-catching, particularly over Haldimand and Norfolk County streams.

Cedar waxwings are very sociable, non-aggressive birds that often travel in flocks, though they may pair off during breeding season. It is very rare to find solitary waxwings. Because they frequently feast on overripe fruit, these birds can become “drunk” on the fermented juices. For the Silo, Dixie Greenwood.
