Did extreme nest predation favor the evolution of obligate brood parasitism in a duck? [PDF]
Ecol Evol, 2022 We used an experimental nest predation study to test the idea that high nest predation rates coupled with high success by laying in aggressive host nests played a role in the evolution of brood parasitism in the enigmatic black‐headed duck. Experimental duck eggs in untended nests suffered massive rapid predation, while eggs in tended nests of the ...
