This close-up of the little guy getting one last nibble in is cropped from one of Scott Taylor's photos.
Two of you got it right - genevra, who knew I was going to a birding thing, and kafilipi, who actually saw the Nuthatch bite me! By far the most common guess from you lot was Hellbob! LOL!
Yesterday morning I went out to Ritter Farm Park down in Lakeville because they were having a birding event. The raptor center was out there, there were stations to build your own birdhouse, and the really cool thing I went down for was Mark and Roger (aka Minnesota Birdnerd) had set up a banding station. The nets were already down when I got there but there were plenty of birds still waiting to be banded. I had met Mark & Roger several times before at Birdchick's Birds 'n Beers gatherings, and Scott Taylor who I had also met at Birds 'n Beers was there taking pictures. I also saw kafilipi out there. Here's another of the photos Scott took of me releasing the Nuthatch. He caught the bird right in mid wing flap, looking pretty darn cool!
