Summary

Learn about the ways that different bird species compete with each other over food and other resources.

I first talk about the concept of the ecological niche, since this is so important to this episode's topic.

Then, I get into the different forms of competition between bird species and present the possible outcomes of that competition. 

Lastly, I briefly touch on the general approaches that scientists take in studying interspecies competition in birds.

Errors and Clarifications

Error - 23:04 min: I say that the second type of competition between species is "exploitation interference". I meant to say exploitation competition. I make this error repeatedly in this section. My apologies!
