Chestnut-sided Warblers were not the only ones working close to the boardwalk at Magee Marsh Wildlife Area on the last days of the Biggest Week in American Birding. Magnolia Warblers were so close that my friend Rich got an excellent shot with his cell phone when they were too close for me to focus at 600mm. This shot is at 600mm. Sony RX10iv. Program mode. 1/500th @ f4 @ ISO 500. Processed in Polarr.
