Commentaires
Eggs were hatching during recording. One chick had hatched when I arrived. The other three were out within 45 minutes. While photographing with remote release, I saw one parent removed shells and drop them in the nearby Rogue River. All shells were promptly removed. Display was the usual broken-wing pattern, plus both birds were lying on the ground, elevating their rumps and wagging their tails. Other Behaviors: Perform Visual Display. Habitat: River. Elevation: 280 m.
