Where to see them: Yellow warblers are found across the Archipelago, from the coast up to the highlands.

When to see them: They can be seen at any time of year.

The main threat to yellow warblers comes from invasive species. The avian vampire fly Philornis downsi affects chick survival, the smooth-billed ani robs eggs from warbler nests and an invasive mosquito has introduced avian malaria which now infects the birds. There is also a worry that the yellow warbler may be affected by increasing urbanisation, with pesticides potentially reducing prey availability. 

Whilst there are currently no specific plans in place to protect yellow warblers in Galapagos, continual work goes into controlling invasive species and researching the effects of urbanisation, which could threaten their population. Yellow warblers are also protected by the Galapagos National Park.
