Rocky the (one-legged!) Rock Pipit. Rock Pipits like to stand on one leg! This individual certainly did, and was amazingly adept at moving one leg up under its feathers and imperceptibly shifting its weight onto the other leg. At first I thought it only had one leg! It did this so quickly!
I am a retired entomologist with a background in quarantine pests and invasive invertebrates. I studied zoology at Imperial College (University of London) and did a PhD on the population dynamics of a cereal aphid (Metopolophium dirhodum) in the UK. I spent 5 years with the British Antarctic Survey studing cold hardiness of Antarctic invertebates and 17 years with the Food and Environment Research Agency. My main interests now are natural history, photography, painting and bird watching.
