Little is known about the population densities and effects of predation and brood parasitism on the Gray Vireo in New Mexico. The Gray Vireo is a Species of Conservation Concern (USFWS 2002), listed as Threatened in the State of New Mexico (New Mexico Game and Fish 2008), and their nests are frequently parasitized by the Brown-Headed Cowbird and predated by several other species. The students will study cowbird parasitism and predation at gray vireo nests, using cameras and observation in conjunction with a larger study on gray vireo ecology. (Mentor: Kathy Granillo)
