Hi   I think I witnessed something quiet unique and was wondering if this has been recorded before. I noticed one of our local kookaburras here in Hobart hitting something on the groung and imgined it to be some small prey however it appeared to be a currawong feather, I shrugged this off and now have noticed the same behaviour some days later, what it appears to me is that the kookaburra is picking up a currawong feather and bashing it into the turf and making a hole which it then pulls out a large worm, I find this truely remarkable and was wondering is this normal
