Détails de l'observation
Strange behaviour - This bird circled Roca Partida all day. Occasionally landing on the rock, but mostly chasing and harassing masked and brown boobies. See photos. When the pursued booby landed (on the rock or sea surface), the shearwater also landed next to it and continued to harass the much larger bird. This behaviour was repeatedly observed a handful of times throughout the day. I could not decide if the shearwater was trying to court the boobies or harass them for another purpose. I have plenty more images of this bird if they are of interest.
