Kurzfassung:
The hypothesis that conflicts between escape, aggressive, and brooding drives proximately govern distraction displays (e.g. “injury feigning”) in nesting shorebirds, is examined. The hypothesis predicts that a bird's direction of departure from the nest while displaying should be along the line predator‐nest, if the predator's search path is directed straight towards the nest at the moment the bird starts to act. Upon intrusions by the observer at 22 nests of American golden plovers Pluvialis dominica the birds departed from the nest, and displayed, more or less perpendicularly to the intruder's direction. As the intruder remained stationary near nests, some of the birds approached, and then departed in distraction display which increased in intensity in spite of increased distance from the stimulus. The study does not support the proximate motivational conflict hypothesis.
