This article explores how intergenerational performance ecology might distinctively contribute to developing an ecological performance practice. It focuses on a practice-led research project, "Wild Life"--a collaboration with professional and nonprofessional child and adult performers. Drawing on critical perspectives in ecology and ecological performance and dance, the article explores the ecological potentials of directing and collaboration in the context of intergenerational performance ecology. Through critically reflecting on examples from the "Wild Life" devising process, an approach is proposed called the agency of practice, which focuses on how human and nonhuman agency can emerge in the creative devising process.
