Canada Warblers are similar in appearance to the Magnolia Warbler and have a similar range. However, they are grayish-black on the back, and the black ‘necklace’ in the males, does not extend over the belly, only over the chest. They have yellow chests, bellies, and throats.
Females and immatures are similar but paler on the back and with a less prominent ‘necklace.’

You can find Canada Warblers in rhododendron-filled conifer forests or aspen and poplar forests, foraging for insects and spiders. They are difficult to find as their numbers have been declining.
Canada Warbler Song:
Nests of Canada Warblers are built near the ground in shrubs or ferns and woven into a cup from grass, bark, leaves, and other plant material. They lay up to six eggs, which take about twelve days to hatch and a further eight days for the young to leave the nest.
Canada Warblers are flying machines that travel over 3000 miles each way from their winter to summer grounds.
