The White-breasted Nuthatch is a regular visitor to my birdfeaders. Mine prefer suet cakes but also devour the seed logs.
White-breasted Nuthatch-Conservation status: Least Concern
I’ve learned to identify their gentle peep, although they can be quite noisy throughout the day. I don’t think I’ve seen any other bird head straight down the trunk of an oak like the nuthatch.
