Question

identify local names for each bird species.

determine what foods each bird species eats.

identify each bird species by using a dichotomous key.

determine each bird species migration pattern.

Explanation:

To study bird interactions, the first step is to identify the species. A dichotomous key is a tool for species identification. Local names (not scientific), food, or migration patterns come after identifying the species. So using a dichotomous key to identify each bird species is the logical first step.

Answer:

C. Identify each bird species by using a dichotomous key.
