摘要：
Three Great Blue Herons were seen feeding on fish 15 km from the shoreline of Lake Erie, in the vicinity of a fishing vessel hauling its nets. These birds swooped down and picked up fish from near the water surface, in the manner described previously for some heron species as ''dipping''. Our observations constitute the first published account for the species of this foraging method and of foraging in association with a fishing vessel in open water.
