Canada Warbler (Cardellina canadensis) - Special Concern

The Canada Warbler is a small, brightly- coloured songbird. Males are more brightly coloured than females, with bluish-grey upperparts and tail and bright yellow under parts. The head is bluish with a black forehead and “sideburns,” which join to form a distinctive necklace of black stripes across its chest.  In the spring, males can be heard singing a distinctive song of clear, liquid notes ending emphatically. The Canada Warbler breeds in a range of deciduous and coniferous, usually wet forest types, all with a well- developed, dense shrub layer. Dense shrub and understory vegetation help conceal Canada Warbler nests that are usually located on or near the ground on mossy logs or roots, along stream banks or on hummocks.

Canadian Population: 2.7 million

Threats to this Species: A reduction in forests with a well-developed shrub-layer has likely impacted Canada Warblers throughout their breeding range. Canada Warblers likely face extensive pressure on their wintering grounds in South America, where deforestation is a widespread problem.

Fun Fact: A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers
