Species at risk in Lanark region

Birds

Black Tern
Black Tern (Chlidonias niger)
special concern
The Black Tern is very social. It breeds in loose colonies and usually forages, roosts and migrates in flocks of a few to more than 100 birds, occasionally up to tens of thousands.
Bobolink
Bobolink (Dolichonyx oryzivorus)
threatened
These birds migrate from Ontario to Argentina - one of the longest migrations of any North American songbird.
Cerulean Warbler
Cerulean Warbler (Cardellina canadensis)
threatened
Since this warbler is a bird of the tree tops, it is often best identified from below. Birdwatchers will recognize adult males by the thin dark band that crosses the upper part of the predominantly white breast.
Eastern Whip-poor-will
Eastern Whip-poor-will (Caprimulgus vociferus)
threatened
Chicks seem to hatch near full moons, giving parents more light for foraging so they can supply the extra energy demands of their rapidly-growing brood.
Golden-winged Warbler
Golden-winged Warbler (Vermivora chrysoptera)
special concern
Golden-winged Warblers tend to nest in loose groups or "colonies" that contain up to ten pairs of breeding birds.
Least Bittern
Least Bittern (Ixobrychus exilis)
threatened
The Least Bittern is more likely to be heard than seen in its dense marsh habitat. The typical call given by males is a hollow, quiet “coo-coo-coo”. When alarmed, they can give a harsh “kek-kek-kek” call. They are most vocal in early morning and evening, but could potentially call anytime during the day or night.
Loggerhead Shrike
Loggerhead Shrike (Lanius ludovicianus)
endangered
Shrikes are sometimes called "butcher bird" because they impale their prey on thorns, barbed wire or sharp twigs.
Short-eared Owl
Short-eared Owl (Asio flammeus)
special concern
Short-eared Owls are nomadic, meaning that individuals wander over large distances, usually settling in areas where prey densities are high.

Fish

Lake Sturgeon
Lake Sturgeon (Acipenser fulvescens)
special concern (Southern Hudson Bay/James Bay population), threatened (Northwestern Ontario and Great Lakes-Upper St. Lawrence River populations)
The oldest known specimen of this fish, from Lake Huron, is 155 years old.
River Redhorse
River Redhorse (Moxostoma carinatum)
special concern
The maximum age reported for River Redhorse in Canada is 28 years.

Insects

Bogbean Buckmoth
Bogbean Buckmoth (Hemileuca sp.)
endangered
Unlike most buckmoths, which live in drier habitats, the Bogbean Buckmoth depends primarily on wetlands that support the bogbean, its preferred food source.
Rapids Clubtail
Rapids Clubtail (Gomphus quadricolor)
endangered
Larvae bury themselves under a fine layer of sediment and “breathe” through the exposed tips of their abdomens.

Lichens

Flooded Jellyskin
Flooded Jellyskin (Leptogium rivulare)
threatened
Flooded Jellyskin is considered rare wherever it occurs worldwide.
Pale-bellied Frost Lichen
Pale-bellied Frost Lichen (Physconia subpallida)
endangered
This lichen grows on the surface of other plants, rocks, or structures and derives nutrients from the air and rain.

Lizards

Common Five-lined Skink
Common Five-lined Skink (Plestiodon fasciatus)
endangered (Carolinian population), special concern (Great Lakes/St. Lawrence population)
When attacked by a potential predator, a skink's tail can "autotomize": spontaneously break off and thrash for several minutes, distracting the predator so the lizard can escape. The tail is able to grow back at a rate of about six millimetres a week.

Plants

American Ginseng
American Ginseng (Panax quinquefolius)
endangered
Aboriginal people have used American Ginseng for a wide range of medicinal purposes including treatment of headaches, earaches, rheumatism, convulsions, bleeding, fevers, vomiting, tuberculosis, gonorrhea and as a cure-all when other treatments failed.
Ogden's Pondweed
Ogden's Pondweed (Potamogeton ogdenii)
endangered
Pondweeds provide habitat for aquatic invertebrates, food for mammals and waterfowl, and hiding places for amphibians and fish.

Snakes

Eastern Ribbonsnake
Eastern Ribbonsnake (Thamnophis sauritus)
special concern
Many species of snakes lay eggs, but Eastern Ribbonsnakes give birth to live young.
Gray Ratsnake
Gray Ratsnake (Pantherophis spiloides)
Endangered (Carolinian population), Threatened (Frontenac Axis population)
This snake is an excellent climber and may be seen up a tree or bush sunning, preparing to shed its skin or hunting for prey.
Milksnake
Milksnake (Lampropeltis triangulum)
special concern
The Milksnake got its name from the false belief that it takes milk from cows in barns, which it often inhabits. Milksnakes cannot drink milk, and are attracted to barns by the abundance of mice.

Turtles

Blanding's Turtle
Blanding's Turtle (Emydoidea blandingii)
threatened
These turtles can survive in the wild for more than 75 years.
Eastern Musk Turtle
Eastern Musk Turtle (Stinkpot) (Sternotherus odoratus)
threatened
Unlike other turtles, the Eastern Musk Turtle rarely leaves the water except when females lay eggs. It spends most of the day resting on the soft lake bottom, foraging for food or basking in the sun under floating aquatic vegetation in shallow water.
Northern Map Turtle
Northern Map Turtle (Graptemys geographica)
special concern
The Northern Map Turtle is extremely wary and will dive into the water at the slightest provocation.
Snapping Turtle
Snapping Turtle (Chelydra serpentina)
special concern
These turtles spend so much time underwater that algae grow on their shells. This helps them blend in with their surroundings.
Spotted Turtle
Spotted Turtle (Clemmys guttata)
endangered
Most female and male turtles look a little bit different. In the case of Spotted Turtles, females have bright orange eyes and chins whereas males’ are dark brown or black.
Wood Turtle
Wood Turtle (Glyptemys insculpta)
endangered
Wood turtles do not begin reproducing until they are at least 17 years old.
