In a forest, different species of warblers (a type of bird) are observed feeding on insects in the same trees. However, each species forages in a specific part of the tree, such as the upper branches, middle branches, or lower trunk. Which ecological concept does this scenario illustrate?

We discussed 3 survivorship curves in class: Type 1, Type 2, and Type 3. Type 3 organisms typically have lots of offspring but few make it old age. Type 1 have few offspring and most make it to old age. Type 2 are somewhere in between. Which organism below would fit into a Type 1 organism based on its likely survivorship curve?
