Question

feeding height (m)
these three species of birds use the same species of tree while feeding. based on the information in the graphic, why do these birds not compete?
these bird species are each active at different times of the day.
these birds live in different parts of the world.
the birds use different zones of the tree so they do not overlap.
these birds actually do compete since they use the same tree.

Explanation:

The graphic shows that each bird species feeds in a distinct part of the tree (middle, top - branch tips, lower and middle - branch bases). This indicates they use different zones. There is no information about activity times or global distribution differences. And since they are in different tree zones, they don't compete.

Answer:

The birds use different zones of the tree so they do not overlap.
