Came across these while looking up something else:
A video from the Humane Society of the United States on ways to deter animals from eating young, tender plants.
And the Web site of Project Squirrel, which recruits citizens to help keep track of squirrel populations in the Chicago area, with informative explanatory video including many cute squirrels (if you don't have enough at your bird feeder).
A big shout-out to the Peggy Notebaert Nature Museum and the University of Illinois at Chicago, which jointly sponsor Project Squirrel, for captioning the squirrel video! I am hard of hearing and, though I can watch TV because it has captions, all the uncaptioned video on the internet is lost on me. So thanks, guys!
