Those little birds are sometimes hard to see, but they sure sound happy. At times I would just catch a glimpse or see more then one bird, but we could hear them on most of the lakes.

Just before loading the canoe one morning to leave our campsite, I tried imatating the sparrows call.  Three or four birds came over from across the small bay and I actually ducked (lol), at least one landed on the branch right above my head, and one bird looked different then the others. They stayed for a minute and soon left. I tried for the rest of the week to get them to come closer again, but couldn't get a repeat.
