Great Blue Herons populate in both freshwater and seawater (salt water) habitats, and also scrounge around in grasslands and cultivating fields, where they pursue frogs and mammals. Most reproducing colonies are situated within two to four miles of feeding expanse, frequently in secluded swamps or archipelago, and close by inland sea and ponds surrounded by forests!
Great Blue Herons eat practically anything whatsoever within evident remoteness, as well as fish, caecilians, cold-blooded vertebrates, small mammals, insects, and additionally other aves. They seize and devour smaller prey in their powerful mandibles or use their bayonet-like bills to spear through larger fish, often shaking them to break or modify the piercing vertebral column before swallowing them down!

She weaves a platform and a ellipsoid-shaped nest cup, lining it with pine needles, moss, reeds, dry grass, mangrove leaves, or small twigs!
Nest building can take from three days up to two weeks; the finished nest can span from a uncomplicated platform measuring twenty inches across to more intricate structures used over numerous years, extending four feet across and nearly three and a half feet deep. Ground-nesting herons use foliage such as salt grass to form the nest!

Great Blue Herons can be sighted throughout the year encompassing North America, though most populations in Canada are present only during the breeding season, and most populations in Mexico are only present during the winter times! 🌨🐦
