Discover nature this week along Missouri streams and bottomland woods, and listen for the low, harsh vocalizations of great blue herons.
Herons nest in colonies – or rookeries – near water. These rookeries can contain hundreds of bulky stick nests which may be used over multiple years.
Herons are mostly monogamous during a season, and each pair incubates 3-to-6 eggs. In mid-July, fledgling herons begin to leave the nest, learning to fly and feed themselves.
