This is according to Bird Guides, a website where avid twitchers can report sightings. According to the report, an Osprey has been spotted flying overhead at Frodsham Marsh, a beloved Cheshire beauty spot. The beautiful bird of prey was last seen at around 10 am on August 11, circling over the River Weaver near the Weaver Sluice Gates. Ospreys are considered a rare breeding bird in the UK, and there are suspected to be around 300-400 breeding pairs. The majority are located in Scotland, although there are growing populations in England and Wales.
