I don't know if it's the same one that hooted loudly to wake us all up on Monday morning, stand on a rock outside my bedroom window, but I got this picture yesterday at the wildlife preserve at Sepulveda Dam. There were three or four grey herons standing in a field, quietly. Astonishing, really.
In shamanism, a heron signifies: The ability to maintain balance. Has a secure inner foundation but not fixed. Clarity of understanding.
