It has a black forehead and nape, and its upper wing is a pale grey. The Tundra Swan Cygnus columbianus, formerly known as the Whistling Swan, is a large bird with white plumage and black legs, feet, and beak. Maternity colonies do not occur in caves or mines because pregnant females need warmer temperatures to raise their young. The Little Brown Bat can be found almost everywhere in the United States and southern Canada.There are three main purposes for the Little Brown Bat to roost: daytime roosting, nighttime roosting, and hibernation roosting. If you live in the Midwest regions of Iowa, South Dakota, North Dakota, or Minnesota, we can provide safe and humane bat removal and inspections for your home. As spring approaches and the ground becomes bare, Snowy Owls move to sit on patches of snow or ice. They are one of several species that use echolocation. The Atlantic Cod (Gadus morhua) is a medium to large saltwater fish: generally averaging two to three kilograms in weight and about 65 to 100 centimetres in length, the largest cod on record weighed about 100 kg and was more than 180 cm long! 1998, Rambaldini 2003, Rasheed & Holroyd 1995, Sarell & Luoma 1994; Vonhof & Barclay 1997. In Indigenous languages, like Mi’kmaq, it is known as k’at or g’at, the Algonquins call it pimzi or pimizi, in Ojibwe bimizi, in Cree Kinebikoinkosew and the Seneca call it goda:noh. The Atlantic Cod may live as long as 25 years. Bats are the most significant predators of night-flying insects. Geomyces destructans causes a disease called White Nose Syndrome (WNS). As its name implies, it is pale tan to reddish or dark brown with a slightly paler belly, and ears and wings that are dark brown to black. The species has been observed in a great variety of habitats, including all forest types, the southern edge of the Arctic tundra and urbanized areas, but it prefers areas close to wetlands, lakes or streams in the summer because of greater food availability. The little brown bat is found in abundance throughout the northern United States into Canada. Adult females are darker, their white feathers barred with dark brown. It can weigh up to 63,500 kilograms and measure up to 16 metres. One non-native species, the Mute Swan, is found in North America,. Unlike most other large whales, it has no dorsal fin. The North Atlantic Right Whale (Eubalæna glacialis) is one of the rarest of the large whales. The Little Brown Bat looks identical to the Big Brown Bat except for the difference in size. Instead, it has both guard hairs and a warm undercoat that trap bubbles of air to help insulate it. Hibernacula are generally in caves or abandoned mines, and are chosen for their high humidity and stable, above-freezing temperatures. At close range, an observer should look for a salmon-red line on the lower bill. In 2006, a major threat for Little Brown Bats appeared in North America. They sleep. Bats also tend to look for places that allow them to adhere to their nocturnal instincts since they sleep in the day, and do most of their traveling and scavenging at night. The tusk grows all throughout a male’s lifespan but slows down with age. This camouflage helps protect the grouse from their predators. These seven gill pores are located one after another behind the eye. Eastern Red Bat (Lasiurus borealis) Since conditions are ideal for the fungus in most Canadian bat hibernacula – caves and mines share similar cool and humid conditions –, WNS is spreading fast. Females that are not reproducing  and males roost in other, typically cooler, locations, in smaller groups. The Tundra Swan’s former name “whistling swan” referred to the sound made by the slow, powerful beating of the wings in flight, and not to the voice of the bird.
