1 - an adult arrived from the NW at 7:18am. Drifted over the main lagoon and then dropped down and landed on the southern shore of the main lagoon. The crane remained at the eastern end of the main lagon - both north and south shores, before taking flight and soaring up high to the east up Rodeo Vallay at 8:25am. Seen in the air for 15 minutes before returning and appearing to drop back down to the lagoon, but our vision was obscured by willow trees at that time. Looked for 5 minutes later when we emerged from the willows along Lagoon Trail and the crane could not be relocated. My second record for the Lagoon and the first to actually land at the Lagoon. Amazing sight!
