I captured this image last month in Iceland. I had been observing and trying my best to get a decent image of these speeders as they brought fish in for their chicks. This particular pair seemed to be cooperating with each other almost as if the bird on the right is indicating that's a good catch. I followed them capturing a few more frames as the flew off staying close together not fighting for the fish. C&C welcome.
