Progress Code: completed Purpose This data was collected to analyse the drivers of Adelie penguin reproductive success in the Windmill Islands, East Antarctica, using Cox Proportional Hazards survival models. We assessed reproductive success for the Adelie penguin colonies breeding on the Windmill Islands (Whitney Point, Odbert Island, Shirley Island, Blakeney Point 66°15' S, 110°33' E) from the 2011/12 – 2020/21 breeding seasons. We modelled nest survival against a range of potential environmental and behavioural drivers assessed over the same time period which are described below. Sites: We used four different sites with five camera locations for this study: Odbert Island = Odbt1, Shirley Island = Shrl1, Blakeney Point = Blak1, Whitney Point camera site 1 = Whit1, Whitney Point camera site 2 = Whit2. Individual nest identifier: For each nest, we developed a unique nest identifier (Year_Site_Nest). This includes the breeding season and camera site the nest was observed in, and also the number of the nest (1-10) observed. Reproductive success data: We used two metrics of reproductive success, breeding success and nest survival to creche. Breeding success was recorded as 0, 1, or 2 for each nest (0 = no chicks, 1 = one chick, 2 = two chicks). Nest survival was measured as binomial data and collected as 0,1 where 0 = nest failure and 1 = at least one chick survived to creche (Success.Fail). Nest failure occurred when either the parents abandoned the nest, both eggs failed to hatch, or chicks died. Failure and creche dates were recorded and the number of days since October 1 were calculated (Nest_Fail_date and Creche_Date). The breeding phase when failure occurred was noted for failed nests (Fail_Period). See BehaviouralData.csv. Environmental covariates: Southern Oscillation Index (SOI) and Southern Annular Mode (SAM) SOI and SAM values were averaged for the October – January (SOI_OctJan and SAM_OctJan) and the April to October (SOI_JulyJune, SAM_JulyJune) periods to correlate with the Adelie penguin ...
