Abstract Title

Interspecific Interactions Between Passer domesticus and Haemorhous mexicanus

Additional Funding Sources

This project is supported by a 2021-2022 STEM Undergraduate Research Grant from the Higher Education Research Council.

Abstract

We are looking at the interspecific interactions between the two bird species Passer domesticus and Haemorhous mexicanus. Previous research shows that P. domesticus and H. mexicanus are aggressive towards each other in the eastern part of the United States where they are both invasive, with H. mexicanus being the most dominant species. We are looking at the interactions over in the Western United States where P. domesticus is invasive and H. mexicanus is native, to see if their interactions differ from those of the east. This can give us a better insight into how invasive species interact with native species in the environment, and how much of an affect those invasive species can have on the environment as a whole.
