The vibrations caused by all the exuberant dancing lures the earthworms to surface resulting in a tasty treat for the birds.
Scientists still aren’t sure why the worms respond to surface vibrations in this way.
One myth is that they are avoiding drowning in the water-logged soil but as worms absorb oxygen through their skin the damper they are the better and can, if necessary, survive several days in water. One theory is that, as worms can travel faster over ground than through, they are coming up to the surface when its wet so they can migrate further without the risk of drying out. A second theory is that the vibrations mimic those made by tunneling moles and the worms are doing their best to move out of the way.
There are 26 species of earthworms in the UK and they are vital in creating a good healthy soil for your plants. Their burrows increase drainage and allow air to circulate and, most importantly, they recycle organic matter back into the soil.
One of the most common species, and the one found in compost bins and sold for use in wormeries, is the Brandling or Tiger worm which has a distinctive stripy pink and red body. They don’t make much impact individually but where you find one worm there will be others and one kilo of worms can eat 500g of dead or decaying material a day.
So next time you’re out dipping around and you spot a worm show it some love and move it to a safe place, it’s your best friend in helping you create that beautiful garden.
