Warblers of Southern Arizona: Lucy's Warbler

Continuing my series on Warblers of Southern Arizona, in alphabetical order, next up:

Lucy's Warbler

Distinctive Identification Marks: smallest warbler; tiny bill, gray above and pale gray below; chestnut rump; chestnut crown patch (usually not visible); plain face with pale eyeing and lores; dark eye;

Frequency: Uncommon

Season: March through August

Range: Southern Arizona

Lower Tree and Brush in riparian woodland and mesquite bosques; likes dry habitats

Nests in cavities of trees or cactus; nests of finely woven twigs, weeds, straw, mesquite leaf stems; then lined with fine bark, plant fibers, animal hair, and feathers

Feeding Behavior:
Gleaning: perched bird takes prey from branch

General Behavior:
Very active; constant movement

Where to Find: Sabino Canyon, Empire Gulch, Catalina State Park, Patagonia Sonoita Creek, Miller Canyon, Madera Canyon

Chance of Finding: Lucy's is the same size and coloration as the Ruby Crowned Kinglet. Without a clear view could even be confused with the Blue Gray Gnatcatcher. The best identifying mark is the chestnut rump. However it is not often showing. The result, 25% in preferred habitat. Someone who can identify it by song will have a better chance.
