Many people refer wrongly to any small fish as a minnow. Properly, minnows are small to large freshwater fish of class Actinopterygii, order Cypriniformes, family Cyprinidae.
Hornet is the common name for wasps in the genus Vespa. They are members of the insect family Vespidae in the order Hymenoptera, which also includes other social wasps like yellowjackets and paper wasps. There are 22 species of hornets worldwide, none of which are native to Canada. However, three introduced species have been found here: the European hornet (Vespa crabro) in southern Ontario and Quebec, and the Japanese yellow hornet (Vespa simillima) and Asian giant hornet (Vespa mandarinia) in coastal British Columbia. The bald-faced hornet (Dolichovespula maculata) is native to Canada, but is actually a species of yellowjacket.
Chickadees (genus, Poecile) are small birds, which live in woodlands throughout Canada, often visiting backyard birdfeeders.
Tropical Asian and N Australian pitcher plants of the genus Nepenthes belong to the family Nepenthaceae. The Australian flycatcher (Cephalotus follicularis) of SW Australia is the only species of the family Cephalotaceae.
The complex social organization, the biology and the industrious nature of honeybees (genus Apis) have long fascinated people.
Moths are distinguished from butterflies by having threadlike or feathery antennae. Most are nocturnal. They vary in size from adults of some leaf miners with wings spreading little more than 3 mm to the Asian atlas moth, spreading 20 cm.
Maples are trees and shrubs in the genus Acer, previously classified within the maple family Aceraceae, but now placed by some taxonomists in Sapindaceae (Soapberry family), which also includes horse chestnut (Aesculus hippocastaneum). There are approximately 150 species of maple around the world, most in the temperate zone of the Northern Hemisphere, and the majority native to eastern Asia. Ten maple species are native to Canada, perhaps the best known being sugar maple (Acer saccharum) of eastern Canada and the northeastern United States. The Canadian flag displays a stylized maple leaf, and maple is Canada’s official arboreal emblem. Maples are not only important to Canada symbolically, they are also ecologically and economically significant.

Climate is often defined as average weather, when weather means the current state of the atmosphere. For scientists, climates are the result of exchanges of heat and moisture at the Earth's surface. Because of its size, Canada has many different climates.
Inuit and subarctic Indigenous peoples have traversed the North since time immemorial. Indigenous knowledge and modes of transportation helped early European explorers and traders travel and survive on these expanses. Later settlement depended to an extraordinary degree on the development of transportation systems. Today, the transportation connections of northern communities vary from place to place. While the most remote settlements are often only accessible by air, some have road, rail and marine connections. These are often tied to industrial projects such as mines.
