Jennifer Clary-Lemon's book "Nestwork: New Material Rhetorics for Precarious Species" explores the relationship between endangered bird species and conservation efforts in Canada. The book introduces the concept of "nestwork" as a methodology for responsible world-making based on embodied knowledge in ecological care ethics. By focusing on specific endangered bird species, such as barn swallows, chimney swifts, and bobolinks, Clary-Lemon offers insights into human-bird entanglements, temporal sovereignty, and ecological care. The book advocates for listening to nonhuman sensibilities and attending to ethical existence during species loss, providing a valuable framework for scholars in various fields interested in multispecies ethnographic research.
