What's flying near you?

We have 2 different (I think) male greater spotted woodpeckers visiting the birdtable, one who announces himself arriving and departing with a 'chack' and one who doesn't. The sparrows don't quite know what to make of them. The table is for the small birds and has a 1½" plastic mesh to keep black birds and pigeons out, you know the plastic stuff used for climbing plants, woody thinks nothing of squeezing through this.
