I've had a window bird feeder on my office window for years. I love it! I once had a little list going on my desk of the various birds that had stopped by. My list included cardinals, blue jays, tufted titmouse, and others. It's great! I can be sitting and working and look up and see a bird stop by to eat. I know other people who have picked them up to put on other windows in their home, giving their kids and adults alike something fun to check out. This morning I had both a male and female cardinal stop by at the same time for a bite to eat. Awesome! We have a lot of birds in Florida and we are lucky enough to get birds that stop by all year long.
