I received this e-mail and images this afternoon from our viewer in England, Pam Birley. She took them using the remote camera 5 and writes: “I watched this bird for about an hour today !!!  I think it may be a juvenile Pacific Coast Peregrine Falcon.  According to Sibley they are darker feathered with mustache merging on head to form a dark helmet.
