BIRDGACHA / FIELD NOTES
Olive Warbler
The Olive Warbler is a small mountain songbird with olive-grey upperparts and pale wing bars. Adult males show an orange-brown head crossed by a dark eye mask, while females have a more yellowish, subdued head pattern. The species in this catalogue is Olive Warbler (Peucedramus taeniatus). It searches foliage and branches for small invertebrates, often high in conifers. Despite its English name and warbler-like behaviour, it belongs to its own family. The combination of head pattern, wing markings and a pine-associated setting is more informative than assuming it shares a lineage with American wood warblers.
How to recognize Olive Warbler
- Bill: a fine pointed bill.
- Outline: a small body with wing bars and contrasting head colours.
- Feeding: searching conifer foliage for small invertebrates.
Where they live
Pine and pine-oak forests from the southwestern United States through Mexico into northern Central America provide the main habitat. Birds often use the canopy, where small prey occurs among needles and branches. Mountain elevation and the distribution of conifers shape local occurrence. Seasonal or altitudinal movements can occur, but the family should not be portrayed as a generic tropical lowland warbler simply because part of its range extends well south of Mexico.
