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?
◦ Environment is important in forming behaviors.
◦ Lovebirds can be trained easily.
◦ There is a genetic basis to behavior.
◦ Behavior can be learned from parents.
