One of my challenges has been to get good high speed video of Welcome Swallows in flight. I have spent a couple of hours at West Belconnen Pond recently trying different techniques. While I am yet to find the perfect technique, I have captured video of them feeding on insects from the water. According to HANZAB, this feeding technique is rarely used.

 

The attached crops of successive video frames show a bird taking an insect (dot above the red arrow in the first picture) from the surface of the water. The birds at WBP have been using this technique frequently over the last couple of days. As the video was taken at 120 frames per second, the five frames shown cover 0.0417 seconds
