A new female for Aberfoyle ospreys?

As reported last week, since the return of our "trouble maker" bird from last season, neither yellow OU nor green DX have been spotted on the nest. Instead, the metal-ringed male osprey was seen on his own waiting for the return of last year's female, Red 6A. She still hasn't returned but the male's attention now seems to have been diverted to a new younger model in the shape of a 4 year old female, ringed white HA, who arrived on the nest on Friday. All we know about this new female is that she was hatched in the Tweed Valley, Scottish Borders in 2007. It is not especially unusual for female ospreys to venture slightly further afield from their birthplace in the hunt for a suitable nesting location. Hopefully white HA and metal ring are going to be our resident couple for the season as we have already had 4 different ospreys on the nest in the last 10 days! As many of you know there is also live viewing of Ospreys in the Tweed Valley.
