The Killdeer (Scientific Name - Charadrius vociferous) is very vocal shorebird found in many parts of North America and can be found in all Canadian provinces.
They are distinguished by the two black bands around their necks and the red ring around their eyes. The call of "deer-deer-deer" is quite distinct.
When nesting, the male will often become vocal to draw predators away from the nest or sometime use a broken wing display to do so.
