Warbler - Chestnut-sided

Fledgling Chestnut-sided Warbler - June 28, 2012

If I had not seen the adult Chestnut-sided Warblers feeding their newly fledged chicks, I would not have been able to identify this bird. Given the very fluffy feathers and almost no color, he must have just left the nest. His constant cheeping - begging to be fed - got my attention.
