Question: how tall are blue heron?
Answer: Great blue herons' size (3.2 to 4.5 feet) and wide wingspan (5.5 to 6.6 feet) make them a joy to see in flight. They can cruise at some 20 to 30 miles an hour. Though great blue herons hunt alone, they typically nest in colonies. They prefer tall trees, but sometimes nest in low shrubs.
