Experts say there are now 11,061 breeding pairs of Gannets in the breeding colony at Bempton Cliffs. This means a 40% increase since the last survey in 2009.
When the research first began in 1969, there were only 22 breeding pairs at the site.
The researchers also counted 798 non-breeding birds, which, when they are old enough to find mates, will add to the numbers.
