Have now had time to look up the birds that we saw today. Both were grey and black.
The first ones were Gray Jays but we also saw some that sounded like Nutcrackers that are often heard but seldom see in the Alps.
On checking these were also Nutcrackers - Clark's Nutcracker.
Jan and Rob decided to see how tame these birds were by putting sandwich scraps on my hat. The nutcracker was the only one brave enough to swoop in and take the food although the Gray Jays would eat from an outstretched hand.
Don't think European Nutcracker's do this!
