I managed to get quite close to this micro-dynamo of a bird, possibly within 3 meters. The RX10 IV's superb continuous AF, close focusing ability and the 24 fps RAW bursts made it quite easy to capture the decisive moments, as the bird was actively feeding on some Kerson fruit (locally called mansanitas or alatires). Total length of the bird from tip of tail to tip of bill is about 4 inches.
