Almost 30,000 pink-footed geese have now made the 500-mile journey from Iceland to Martin Mere Wetland Centre in Lancashire.
Over the next few weeks, the total across the county is expected to swell to an estimated 100,000.
A wildlife census on one day this month showed Martin Mere had 29,400 geese, 18,140 were seen at Morecambe Bay, 4,450 at the Wyre Estuary, 9,287 on the Ribble Estuary, 18,051 at Taylor’s Bank, 3,000 at Simonswood and 100 at Rainford Mosses.
The geese spend the summer in Iceland. They will ultimately spend the winter in the south of England after using the North West as a service station to rest and re-fuel for up to three weeks before continuing on their journey.
Over the last 30 years, there has been a massive increase in the number of geese travelling through Lancashire, which will often get 25 per cent of the Icelandic population of pink-feet.
