Daylight Robbery I/II
The original show was filmed in an English back
yard on how squirrels defeated 'squirrel proof' bird feeders.
If you can get the whole
video Daylight Robbery I/II about squirrels defeating obstacle courses and
'squirrel proof' it great. Squirrels exhibit cooperative problem solving,
situational awareness, and risk analysis.
The long tube the
squirrel dashes across is actually a roller, they will fail an obstacle and try
again until they get thru to the food.
