The Nesting Great Blues
I’m lucky to have close access to the Green Cay and Wakodahatchee Wetlands (Seminole for “created waters”), and when we’re not able to hike the Everglades or some of the other far-reaching natural area, a stroll around these boardwalks will soothe my spirits. It’s full-on nesting and baby season, and while I’ve posted some pics of the anhingas and others (the baby gators I’ve yet to post), I’ve saved the biggest for last: the ever-so-graceful Great Blue Herons. Their displays at the rookery fuel the attentions of every amateur and professional photographer and birdwatcher for miles, and the meek (*me*) have no place if it’s crowded…which is fine, because while the herons are divine, there’s plenty of other loveliness to be found when no one’s looking.
The Great Blue parents share the responsibilities of feeding their young at the nest, by hunting on a full-time schedule and regurgitating the food. The battle for food is brutal among the chicks; the first to hatch is more experienced in food handling, and consequently grows more quickly than the others. Such aggression in the interaction with the sibling chicks (as well as the discrepancy in size) can be seen at the Wakodahatchee rookeries, where the humans root for the younger, weaker chicks that consistently lose after fierce battles for food. This particular nest had two young herons — there initially may have been more eggs however, because we spied an iguana lurking in the depths of the rookery, obviously looking for eggs to steal.
