SNACK-SNAFFLING
SEAGULLS Have you ever had a seagull steal your snack? New research has shown that these clever birds work out which snacks are worth stealing by watching what humans are eating. To test this, one scientist sat on Brighton beach eating a pack of crisps while others filmed seagulls as they pecked at empty crisp packets placed on the beach nearby. Before the researcher tucked into the crisps, the seagulls weren’t very interested in the crisp packets, but once they saw the snacking, half of them hopped over to investigate the empty crisp packets, with 95% pecking at the same colour crisp packet that the researcher was eating from!

After reading this magazine, you’ll know that sea caves are created by water erosion… but did you know that caves can also be shaped by bat poo?! Scientists in Brazil studying iron ore caves underneath the Amazon rainforest found that the caves where bats lived were larger and had more stalactites and stalagmites than those without bats. Bat guano (poo) in the caves mixes with water to make acids that dissolve the iron, sculpting the caves over thousands of years.
