Recently I got back into birding again after a hiatus of several years. The pickup of this hobby is the acquiring of a new lens for my camera. As I am still relatively unfamiliar with the North American birds (I am originally from Europe), I appreciate your help.
The first one I am unsure about is this one which I spotted in the afternoon in the middle of a relatively dense (small) forest in the Quarry Hill nature center in Rochester, MN. I believe this to be a Wren, however, which kind I cannot seem to figure out. There were no other birds that I could see at that moment.
A maybe unrelated question, but does anyone have a suggestion for a good bird determination book that I can buy for North American birds? I like searching for information on the internet, but a book is still more convenient for me.
