Black Terns (
Chlidonias niger/Zwarte Stern) return from end April into May. In The Netherlands they breed colonially in well-vegetated lowland lakes, e.g. cut-off branches of the big rivers. They have a light jaunty flight, hunting insects over the water surface like a big leisurely Swallow. The AF of my Canon EOS 40D camera had a hard time to capture this foraging behaviour. First of all shutter time must be 1/800s of faster to avoid motion blur (with a 500
mm tele). The best strategy is to use the central AF point, set the camera in servo high-speed mode, dismount any converters and try to keep the bird in the middle of the viewfinder. The composition can be made later on in Photoshop by cropping. During postprocessing I also flipped this image horizontally, so that the birds flies to the right. This makes the picture easier ‘to read’. The blurry circles in the background are flowering Yellow Waterlily (
Nuphar lutea/Gele Plomp).
