Over the last few years, I have noticed that Gulls mainly Herring Gulls sometimes Black-headed Gulls do what I call a “worm dance”.They stand on grassland often on the side of the road or in the centre of a roundabout either alone or in small groups and tap their feet. This tapping seems to encourage the worms to the surface, making a good meal. I have been watching bird behaviour all my life and this “worm dance” is relatively new. The birds must pass this trick on to each other as it is widespread here in the UK. I wonder if Gulls in other countries do this?

A nearby park has hundreds of mole holes. They have a front door and a back door. Birds will disturb the front hole and then swoop to the escape hole where they often catch the critter trying to escape. Birds are pretty smart!

I don’t recall seeing this behaviour before Andy but I wasn’t looking for it. I’ll let you know If I see this and I’ll ask my bird expert friend.
