I posted this on the LG Osprey thread but don't thnink this is appropriate and can't find another so sorry, haved started a new thread................
Question: Why did we see, particularly in the 1990's, different reactions from the resident pair of Ospreys to intruding Ospreys:1, Alarm call and defending of the nest to chasing the intruder away.2, No alarm call but an adult circling peacefully with the intruder until both disappeared.A possible explanation is that in 2 the intruder was recognised as a chick from the nest frpm a previous year (probably male as they tend to return much closer to their natal nests to prevent in-breeding, rather than females than tend to disperse longer distances) BUT,,,,,,,,,,,,,,,,, when they fledged from the nest they were in juvenile plumage............. having returned at least 2 years later they would look - TO US ............. much more different!Explanations for this beaviour VERY welcome!
Some people think Ospreys are a matter of life and death. I don't like that attitude. I can assure them it is much more serious than that.

Osprey Chat CRINGER - which has fallen onto page 2, otherwise you'd'a seen it.
I don't know whether you could then delete this thread, in the cause of not having too many in the LG Osprey forums (which irritates other RSPB Community users no end).
