There is a pair of Peregrine Falcons who roost at the top of the Bankside Power Station chimney. For the month of August, the RSPB have a stand under the Foster bridge with telescopes which allow you to see them.
Otherwise if you have very powerful binoculars 50x or so, you may be able to catch a glimpse of them after the end of this month.
>Hmmmm, maybe I am not the type of supporter the RSPB needs.
If not, that is because the RSPB has lost the ability to make logical decisions. If you want Perigrine Falcons, then you lost pigeons.
There are one or two areas in the Scottish Highlands where it is permitted to shoot Golden Eagles - owing to the presence of the Black Grouse. Other than that, the RSPB is not prepared to accept that there is a maximum sustainable population for a particular raptor.
The high level of raptors in some areas is now causing a problem for certain song birds.
