Tether and Torment

Thousands of birds are forced to endure a miserable existence in bird of prey zoos in the UK including owls, eagles, vultures and many more species.  Tied down, manipulated and starved purely for entertainment -  this is no life for a wild bird. 

Our investigation has shone a light on the daily suffering that birds endure in captivity. Read The Guardian coverage here. 

What we uncovered was shocking: 

  • Birds were tied down (tethered) in three quarters of all zoos
  • Over a third of aviaries did not meet the recommended size, allowing three wingspans of a bird. Some birds lived in such cramped conditions they could not even stretch out their wings.
  • A third of all enclosures did not have access to clean drinking water
  • Stress was witnessed in birds including bating (attempting to fly when tied down), chewing at leg straps, body posture changes and beak clapping.
  • In one method of training used across the industry, handlers starved birds of food, sometimes for days at a time, to make them perform desired behaviours.
  • At the displays watched, birds spent on average just 11 minutes, 18 seconds flying
  • Over 40% of zoos did not hold a licence despite meeting the criteria

These are just a few of our key findings. Read the report to find out more:
