Once again I used Faber-Castell polychromos pencils. They are my favourites.
We have a lot of Jays in the woods where we walk each day. Now the leaves have dropped we see them much more often. You can always tell them as there is a flash of blue and then white as they fly away. They also have a strange strangled croak so you can still tell when they are around.
They are great hoarders of acorns and it has been a very good (mast) year for acorns here. Their relationship with oak trees is reflected in their scientific name Garrulus glandarius. The second part is derived from the Latin for acorn.
An individual Jay may hoard as many as 3,000 acorns and these will provide the bird with food over the coming months. Jays have an amazing ability to recall the location of their hoarded acorns, although it is known that (during the summer) they can use the presence of a newly germinated sapling to reveal the presence of an acorn at its base.
