The Northern Beardless-Tyrannulet is the only United States representative of the Elaeniinae, a large subfamily of mostly South American tyrannid flycatchers.

Less than 5% of the population occurs in the United States.
A group of beardless tyrannulets are collectively known as a "shaving" of tyrannulets.
The Northern Beardless-Tyrannulet has a large range, estimated globally at 1,500,000 square kilometers. Native to Costa Rica, Belize, Guatemala, El Salvador, Honduras, Nicaragua, the United States and Mexico, this bird prefers savanna, wetland, desert, forest, and shrubland ecosystems and can also reside in rural and urban areas. The global population of this bird is estimated at 500,000 to 5,000,000 individuals and does not show signs of decline that would necessitate inclusion on the IUCN Red List. For this reason, the current evaluation status of the Northern Beardless Tyrannulet is Least Concern.
