Hungerford’s crawling water beetle is only found in three rivers in Ontario’s Bruce County and five rivers in northern Michigan. Small changes to their aquatic homes could have big impacts on this globally rare insect.

Habitat loss and fragmentation, and nest predation by raccoons and skunks, are the most significant threats to Blanding’s turtle populations. Other threats include motor vehicle collisions and illegal collection for the pet trade.

Although eastern foxsnakes have proven to be adaptable when it comes to humans encroaching on their territory — for example, using sheds and other structures for shelter — increased development is putting this unique species at risk.

In southern Alberta, one of the province's most endangered animals is gradually, inexorably dwindling away due to habitat fragmentation. It is not a direct relative of the invasive brown rat and doesn’t spread disease or harm crops.

A medium-sized songbird, the loggerhead shrike is named for its disproportionately large head. They use their hooked bills to catch small prey such as mice, frogs, grasshoppers and beetles. Of the twelve subspecies of loggerhead shrikes across North American, two are found in Canada.

This group of aerial insectivores has experienced greater declines than any other group of birds in North America. In Canada, the trend is most severe in the Maritimes. Understanding the reasons for decline is a key first step in recovery.

Now on the brink of extirpation from Canada, this frog is found only in British Columbia's lower Fraser Valley, where it is believed that only 300 breeding individuals remain in small, widely scattered remnant populations.

The roseate tern is a graceful creature whose white, forked tail looks like long streamers when in flight. This endangered seabird experienced sharp declines during the 1970s. Today, there are fewer than 250 adults in Canada.
