Clip Description

The common kingfisher is easily identified by its bright blue and orange feathers. It has a long, dagger-shaped bill that helps it to hunt for fish and small invertebrates like dragonfly nymphs. Its transparent eyelids protect its eyes and allow it to see underwater.

In this fascinating clip, a kingfisher has been filmed in slow motion as it dives into a river to catch small fish. What do you predict the kingfisher’s strike rate will be? Watch the clip to find out. 

Quick Whiteboard Challenge
