Chestnut-sided Warbler (Dendroica pensylvanica), Boyce Thompson Aroboretum, Pinal County

This Chestnut-sided Warbler was found by Steve Ganley and Roy and Jill Jones on 9 November 2008 in the picnic area at the Boyce Thompson Arboretum near Superior.  It was photographed by Brendon Grice on 03 January 2009

Chestnut-sided Warbler is a casual transient and winter visitor to Arizona.

Even when it completely lacks any Chestnut on the sides, nonbreeding Chestnut-sided Warbler is a distinctive bright yellow-green above and unstreaked grayish-white below. It also has wingbars and an eyering. No other warbler has this combination of features.
