Least Tern (Sternula antillarum) Science Article 5
Predation is difficult to observe and quantification of impacts have consequentlybeen difficult, especially for predators active at night. Using night-capable camerasplaced throughout a California least tern (Sternula antillarum browni) colony I examinedrates of predation by a complex of potential predators. I identified and quantified directand indirect effects for each potential predator observed in the colony at night. Smallmammals, European starlings (Sturna vulgaris), great horned owls (Bubo virginianus),opossum (Didelphis virginiana), and coyotes (Canis latrans) were observed in thecolony.
