To spot warblers watch for brief flashes of color or quick, active movements in the leaves of trees and shrubs. Be patient for the quick glimpse to reveal a more complete look at the bird. Since warblers tend to use the same perch or same area of a tree for several minutes at a time, that quick movement that you spotted can help pinpoint a spot that will lead to a good view as the bird hunts insects all around int perch.
Birding by ear is another great way to locate warblers. Many warblers will perch in the open to sing as part of their territorial displays or courtship behaviour, so taking time to learn the warblers unique sounds can help you learn to locate and identify the birds in the area.
Offering mealworms and suet as supplemental food sources can increase your chances of attracting warblers to your backyard. However, be sure to avoid spraying insecticides or pesticides that would remove the birds’ preferred food sources. Even if warblers aren’t interested in the feeders, an active birdbath can attract different species, particularly with moving water such as a dripper or bubbler. Offering nesting material can encourage these birds to nest nearby, ensuring that they take advantage of supplemental food and water all summer long.
