Clip Description

The natural world is full of fascinating partnerships, whereby two very different species depend on each other for their survival.

In this fascinating clip, red-billed oxpeckers can be seen clinging to the body of a giraffe with their sharp claws. These small birds spend most of their life on the world’s tallest mammal. This is because a giraffe’s body provides an oxpecker tasty morsels of food in the form of ticks. The giraffe benefits from this relationship because ticks are blood-sucking parasites that carry diseases, so it is important to have them removed. Why might an oxpecker pluck hair from a giraffe’s mane? Watch the clip to find out. 

Quick Whiteboard Challenge

One morning, an oxpecker ate some ticks that were hidden within the coat of a giraffe:

  • The number was greater than 10 but less than 30.
  • If you divide the number by 5, there is a remainder of 4.
  • If you divide the number by 4, there is a remainder of 1.

How many ticks did the oxpecker eat?
