|A young eagle - note the white tail and white undersides to its wings|
|A male black grouse at a lek. An easy target???|
I watched for about half an hour and the eagle had no luck. Black grouse are generally only occasional prey for an eagle, but if this one does learn to catch them, then he has breakfast lined up every spring as the birds not only congregate but make a bubbling call as well, alerting the eagle to where they are. However, as eagles are generally lazy hunters it might well be that it's all too much hassle.
