Which of the following is an example of a learned behavior?
birds scattering at the sight of a hawk
birds returning to a backyard bird feeder
birds singing to establish their territory
birds competing for food in the feeder

tl;dr - For gradpoint it's B.

If the bird found a food source in the feeder several times, it has learned that it can survive off of it. Therefore it returns to the feeder.

Hope this helps~
