In the last year in Sherwood Forest, rangers have ringed the highest number of birds in a year, including 315 blue tits, 70 great tits, 21 coal tits and 41 nuthatches.
At least eight of the 12 bat species recorded across the county were also observed across the site.
During the summer, rangers counted more than 200 bats from one roost, Center Parcs said.
A spokesperson for the wildlife trust, which works with Center Parcs, said the records from this year’s count were “fascinating”.
“Center Parcs Sherwood has long had a healthy bat population, supported by the efforts of the rangers in installing roosting boxes and to have red kites, a species that was once extinct in England, now nesting shows that with effort we can turn the plight of cherished species around,” the spokesperson added.
The charity added that it hoped the creature count would inspire others to record the wildlife they see around them.
