As I was waiting for the sun to appear (for this picture and this picture), a flock of migrant geese flew low over Galway Bay near the diving board in Salthill.
Picture taken with a Canon 40D fitted with a 100-400mm Canon zoom set to 365mm (according to the image file) which gives an effective focal length of 584mm. ISO was 400, aperture was f11 and the shutter speed was 1/400th of a second.
