I have made few trips to photograph Avocets recently. I had some specific shots in mind that I wanted, the first being of the young feeding, which worked out quite well. The other was some nice portrait shots of an adult with a reflection, this didn't go quite to plan, as is usually the case, typically when the chance came to get something near, the only cloud in the sky went in front of the sun!
It amuses me that the adults attack any other birds that come near, no matter how large they are, such as Geese and Herons, I have even seen them chase a Hen Harrier away. It seems that they become so obsessed with this defensive behaviour that they actually forget about their independent but vulnerable chicks which have wandered off to feed, sometimes up to 20 or 30m away from the parents.
