When building a nest, a female fisher's lovebird cuts long strips of vegetation and carries them to the nest site one at a time in her beak. the female peach-faced lovebird cuts short strips and carries them to the nest tucked under her back feathers. hybrid female offspring cut intermediate-sized strips and attempt to tuck them under back feathers before carrying them in their beak. what does this demonstrate about behavior?

The observation clearly shows that certain behaviors are genetically controlled

Explanation:

From the observation, the Fishers bird uses long strip while the Peach-faced uses short strips and there offspring uses intermediate. It is an indication that the behavior of the length of strips cut by the bird is under genetic control and it can also be concluded that both the Fisher bird or Peach-face bird does not have complete dominance over length of strips cut for nest making.
