Where's Waldo? - Seagull Edition
You may or may not be familiar with the 'Where's Wally?'/'Where's Waldo?' books, which feature illustrations by Martin Handford. The aim of the game is to find Wally/Waldo in the picture, where he is hidden amongst a group of people dressed similarly, but not exactly the same.
Here is the seagull edition - in the photo we see an island filled with Black-Headed Gulls. However, not all of them are the same - amongst them is a Mediterranean Gull.
A Mediterranean Gull has a black head (unlike the Black-Headed Gulls, which have black face masks). The Mediterranean Gull also has a red beak while the Black-Headed Gulls' beaks are black.
Can you spot Waldo the Gull?
