Mr & Mrs GSW

When I put up this type of feeder last winter more than 99% of the visiting great spotted woodpeckers were males (for reasons I can't explain).  I put this one up at the weekend and the first bird to visit was a male (there is a slight variation in colours as the sun was going in and coming out)

but minutes later there was a female..

Since then it has been all males again.  The only difference this winter is that the feeder is a complete trunk going down to the ground rather than a short section sitting on the bird table.  It will be interesting to watch what happens over the next few weeks.
