Species at risk in Halton region

Amphibians

Jefferson Salamander
Jefferson Salamander (Ambystoma jeffersonianum)
threatened
Unlike most small animals, Jefferson salamanders can live a very long time – up to 30 years.

Birds

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.
Henslow’s Sparrow
Henslow’s Sparrow (Ammodramus henslowii)
endangered
The Henslow’s Sparrow is a short-distance migrant, travelling only as far as the southern United States, primarily from Texas to Georgia.
Hooded Warbler
Hooded Warbler (Wilsonia citrina)
special concern
Although these warblers appear to form monogamous pairs, recent DNA studies found that only about two thirds of females produce offspring that are fathered by their social mate.
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.
Louisiana Waterthrush
Louisiana Waterthrush (Parkesia motacilla)
special concern
The Louisiana Waterthrush is among the earliest long-distance migrating birds to arrive back to Canada in the spring, typically arriving by mid-April.
Peregrine Falcon
Peregrine Falcon (Falco peregrinus)
special concern
The peregrine falcon is one of the world’s fastest animals, and has been clocked diving for prey at speeds of 160 km an hour.
Prothonotary Warbler
Prothonotary Warbler (Protonotaria citrea)
endangered
The Prothonotary Warbler was named after legal clerks in the Roman Catholic Church, known as prothonotaries, who sometimes wear a golden hood and a blue cape.

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.
Redside Dace
Redside Dace (Clinostomus elongatus)
endangered
Redside dace are the only fish in Canada with the ability to jump out of the water to eat.
Silver Shiner
Silver Shiner (Notropis photogenis)
special concern
Silver Shiners are easily confused with Emerald Shiners and Rosyface Shiners, which may have contributed to the fact that they were only confirmed in Canada in 1973, but may have always been present.

Insects

Rusty-patched Bumble Bee
Rusty-patched Bumble Bee (Bombus affinis)
endangered
The Rusty-patched Bumble Bee gets nectar from flowers by biting a hole in the outside of it and sucking up the nectar with its tongue. This behaviour, called “nectar-robbing”, leaves marks on the flower than can help researchers detect the bees’ presence in an area.

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.

Mammals

Woodland Vole
Woodland Vole (Microtus pinetorum)
special concern
Woodland Voles are monogamous, and both males and females participate in caring for the young.

Plants

American Chestnut
American Chestnut (Castanea dentata)
endangered
People used the American Chestnut for treating numerous ailments (from coughs and dermatitis to heart trouble), as a staple food and beverage, to build shelters, for firewood and as a source of dye. Early settlers soon realized the many important uses of this tree.
American Columbo
American Columbo (Frasera caroliniensis)
endangered
American Columbo may live for many years but it flowers only once and then dies.
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.
Broad Beech Fern
Broad Beech Fern (Phegopteris hexagonoptera)
special concern
Broad Beech Fern reproduces through spores. The spores are contained in a case-like structure called a sporangium. The sporangia burst upon maturity at the end of summer and the spores are scattered through the air.
Dense Blazing Star
Dense Blazing Star (Liatris spicata)
threatened
Dense Blazing Star is able to grow in soil that is contaminated with cadmium by turning this toxic heavy metal into a non-toxic form in its tissues.
Eastern Flowering Dogwood
Eastern Flowering Dogwood (Cornus florida)
endangered
The bright red fruit of this tree is poisonous to humans but can be eaten by over 50 species of birds and small mammals. These animals help distribute Eastern Flowering Dogwood seeds throughout forests.
Hart's-tongue Fern (Asplenium scolopendrium americanum)
special concern
Hart’s-tongue Fern has very specific habitat requirements, making transplantation and artificial propagation difficult.
Hoary Mountain-mint
Hoary Mountain-mint (Pycnanthemum incanum)
endangered
Hoary Mountain-mint is a very fragrant plant that is attractive to bees and known to produce high quality honey.
Red Mulberry
Red Mulberry (Morus rubra)
endangered
Unlike most fruit trees that are pollinated by insects, the flowers of this plant are pollinated by the wind.

Snakes

Eastern Ribbonsnake
Eastern Ribbonsnake (Thamnophis sauritus)
special concern
Many species of snakes lay eggs, but Eastern Ribbonsnakes give birth to live young.
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.
Spiny Softshell
Spiny Softshell (Apalone spinifera)
threatened
The Spiny Softshell turtle captures crayfish and molluscs by partially burying itself underwater in the sand or mud and snatching unsuspecting prey. Its snorkel-like snout allows it to take a breath of air while submerged.
Wood Turtle
Wood Turtle (Glyptemys insculpta)
endangered
Wood turtles do not begin reproducing until they are at least 17 years old.
