The Thick-billed Vireo has a small range, estimated globally at 14,000 square kilometers. Native to the United States and nearby island territories and nations, this bird prefers subtropical or tropical shrubland or forest ecosystems. The global population of this bird has not been quantified fully but does not show signs of decline or fragmentation that would necessitate inclusion on the IUCN Red List. For this reason, the current evaluation status of the Thick-billed Vireo is Least Concern.
