There are quite a few theories as to how the bright green parakeets that fly across London and other areas in the south of England got here – did they escape a movie set? Were they released by Jimi Hendrix? And how has this non-native, sub-tropical bird survived so well in the UK?  In this episode, my cousin Katie and I discuss the Ring-necked parakeet.
