Scimitar-billed Woodcreepers vs. snake

Description:

South American species with a long curved bill with a dark chestnut head and two whitish lines on face, above & below eyes. Breast and belly whitish and heavily streaked. Chestnut tail.

Habitat:

Open woods, savannahs and gardens. Climbs tree trunks probing the bark, vocalizing all of the time. Prefers myriapods and spiders but accepts other arthropods and apparently small snakes.

Notes:

As the pair were fighting with the snake, a Rufous Hornero and a Great Kiskadee tried to get in on their action but were chased away. The pair then pecked the snake into submission with their scimitar-beaks and then flew off with it. Snake species unknown.
