outside Ardea hide, in tree near the grass which also had a deceased small rabbit on that the Brown Falcon was guarding. Took photos then went on our way to leave it in peace. Over 2 1/2 hours later when coming back the Brown Falcon was still there. Unfortunately it chose a bad spot as the tree was near the pathway so had many interruptions but amazingly had stayed for so long. Was still there when we left mid afternoon.
