Crested Lark reacting to threat - Dhahran Hills

Whilst birding at the spray fields I saw this Crested Lark fly in very close to me acting in a very agitated maner. First it stood upright and looked around nervoulsy and then it saw something that it did not like and crouched down low to avoid what I suspected was a treat to the bird. When looking around to see what was the issue I saw a Western Opsrey flying over heading towards the percolation pond and its favoutie perch of the dead tree nearby. This was a great example of how many species of bird react to treats to them to lessen the cance of being predated.
