[Mystery bird] Pygmy Batis, Batis perkeo, photographed near the Pangani River Camp, Tanzania, Africa. The photographer writes: “I was incredibl[y] lucky to get such a good view of this little fast-moving guy. He actually responded to pishing, and sat there exposed for 10 seconds or so, allowing photographs in the late afternoon sun!” [I will identify this bird for you in 48 hours]
Nikon D300, 600 mm VR lens, ISO 400, 1/250, f/6.3, Exposure Compensation 0.
