Yes I know. There are many pairs of these birds on the lake along side my home. Wonderful capture. I have tried, without success, so far, to capture these fast moving birds, however, I do have some lovely photos of them with their young. They are very devoted parents....))
Actually I hate to say but as the chicks get older they start to kill younger ones off by pecking them to death ;-( some say it is to keep the pike from eating the older ones!
I haven't noticed any of this behaviour amongst the pairs with chicks here. Although alot of chasing goes on the chicks from this years breeding season all seem to get on well together within a tolerable distance. Don't mind coming close for any morsel of food I might have. Don't have large birds of prey here ....))
