Broad-billed rollers like catching flying insects as food.Just aroud sunset , they become active to have their dinner .
The picture is a old picture taken near ten years ago .I used a SRL camera , 200mm f/2.8 len and a flash gun to take it (Because it is so dim for focusing and considering the effective shooting distance of frash gun that I could only use 200 mm large aperture len )The image posted was scanned and enlarged 2x .

Amazing you could get the shot
