The Fischer’s lovebird builds its nests with long strips of vegetation that it cuts with its beak. A closely related species,

the peach-faced lovebird, cuts shorter strips for its nests. When these two species are interbred, the hybrid offspring cut strips

of intermediate length for their nests. These observations suggest that this aspect of nest building is

1. an innate behavior.

2. the product of insight learning.

3. influenced by imprinting.

If a young song sparrow is raised in isolation in a soundproof chamber, it will sing a nearly normal song when it is mature. However, it will be able to sing more variations of the song if

it is allowed to hear other birds sing as it grows. These findings indicate that

1. the ability of song sparrows to sing is a learned behavior.

2. song sparrows use classical conditioning to teach themselves to sing.

3. sounds produced by other birds cause young song sparrows to sing.

4. song development in this species involves both innate behavior and learning.

Geese that are exposed to a moving box during the first two days after hatching will imprint on the box. Geese that are totally isolated from any moving objects during the same

period will never imprint on anything. These results show that

1. young geese must see some type of box to imprint correctly.

2. the first two days after hatching are a critical period for imprinting in geese.

3. geese have an instinctive tendency to avoid moving, box-shaped objects.

4. geese must be exposed to their mother more than two days after hatching to imprint on her.
