The Warbling Vireo has a large range covering much of the Americas and the nearby island nations and territories to which it is native. This bird prefers boreal, temperate, subtropical, or tropical forest ecosystems as well as inland wetlands such as rivers, streams, creeks, and waterfalls. The global population of this bird has not been fully quantified but does not show signs of decline that would necessitate inclusion on the IUCN Red List. For this reason, the current evaluation status of the Warbling Vireo is Least Concern.
