Hermit Warbler, 5/28/13 (above)
and another one 6/18/17 (below) at Ecola Forest Preserve - difficult to get very close, but managed to record this one singing
Sony RX10 IV with fixed f2.4-4, 24-600mm (25x optical) zoom lens. This superzoom camera has a 1-inch, 20.1-megapixel sensor. The viewfinder is great, making it easy to find the bird. Zoom and auto-focus are very fast, making it more likely to get the photo before the bird is gone.
