Adders caught performing rare 'dance' in spring sunshine

Twisting and writhing in the spring sunshine - these two males adders are captured performing a rare 'dance' to establish which one is the boss. The striking reptiles, sporting their distinctive stripey livery, are seen chasing one another across grassland in the Scottish Highlands. The tussle among the dried bracken and moss lasted just a few minutes before one of the snakes slithered away to fight another day. This video was filmed on the April 22nd 2021.
