Hello,
HAZY was telling me that woodpeckers and corvids like to eat nuthatch eggs/chicks, and I was wondering if anyone else had any recorded cases or examples of this happening?

Morning Kizzy, the corvids and GSW's will predate any egg or nestling not just Nuthatches ! With regard to suitable nuthatch nest-box, we bought 4 woodstone ones like THIS and had two pairs of Nuthatches using them. The hole needs to be 32mm but they will narrow that entrance hole themselves with mud front door !
