Northern Yellow Warbler

The yellow warbler (Setophaga petechia) was split into two species in October 2025: the migratory northern yellow warbler (S. aestiva) which breeds across North America and the non-migratory mangrove yellow warbler (S. petechia) which is resident in the coastal mangroves in the Caribbean, Central America and South America. I'd previously done a post on the yellow warbler on March 23, 2025 which really only featured the Galapagos yellow warbler. I've subsequently seen more yellow warblers since then and will do this post on the northern and a post tomorrow on the mangrove species. 

My most recent photo of a northern yellow warbler - in Tikal NP in Guatemala. 

This and the next two photos are of the same bird in Big Morongo on May 20, 2023.
