Breeding success of Gentoo penguins at Bird Island, South Georgia, from 1982 to 2020
The breeding success (calculated from nest and chick counts) of Gentoo penguins is monitored annually at Bird Island, South Georgia. The number of incubating nests and chicks reaching fledging stage are counted in several Gentoo penguin colonies. Data exist from 1982 onwards. This work was funded by...

Chicks are counted at all the above colonies 98 days after peak laying (when 75% of monitored nests have laid eggs). Separate counts are made for the Upper and Lower colonies at Natural Arch and Mountain Cwm. Counts are made on the appropriate dates according to the dates used for the breeding counts.
