I don’t think these photographs are near as good as the first Warbler, but still it’s a bird I rarely see.
I might have missed them in the past thinking they were Nuthatch. They travel around the trees using the same crazy upside down methods.
The above might have been a Woodpecker if you spotted one from a distance. This will most likely be the last seen this year. Temperatures have finally dropped so they will be moving on.
