Curious behaviour by Rooks

I'm no expert M but-I reckon they're Rooks, Rooks are gregarious, Crows tend to be in 2's max(Spring nesting time) the moss thing I reckon is for worms/bugs. Moss grows in damp/shadowy cool areas so there could be food under it.

Might it be this?.

You'll probably notice that whilst they do this they tend to go around in a big circle eventually. It's simply looking for food and if they're returning then it means you have a healthy lawn, or did until they made a mess of it. Just hope they don't tell their mates.

Talking of Rooks & Crows, have a look at my story re Scottish Vandals in the Stories section!

Have just checked and discovered that as the story has been up for a little while it has now gone into the less obvious file so will need looking for.

But basically it is a warning to those members visiting the West highland Coast Nr Bunree and Fort William, to either fold in or cover their door mirrors at night because the Hooded Crows up there have a nasty habit of attacking their own image in the door mirrors and as a result quite frequently break them!  Its happened to me and as mine were heated etc were not cheap to replace!

I walked past a fantastic Rookery (congregation of Rooks!) the other week, near Birling Gap in Sussex. Did you know that Rooks are one of the most intelligent birds? Scientific studies have shown they rival Chimpanzees when it comes to tool use.

Rooks only build nests from materials plucked from trees e.g. live twigs; and don't tend to use material found on the ground. 

They're part of the Corvid family, along with your typical Carrion Crow & Jackdaw. I reckon JCB4X4 could have the answer - very possible indeed!

Did you know that Crows are one of the only birds whose young show signs of playing? 

OH has reared quite a few crows, rooks and jackdaws. The last one went on to join fellow rescuees at the rspca wild life centre at West Hatch, it had originally been taken from a nest by a predator. They are all very intelligent birds and lovely to watch but I'm glad I don't live under a rookery...they are early risers and very noisy!
