Australasian Gannet Foraging Effort and Movement Data Over Three Breeding Seasons

Australian Marine Parks research tracks the at-sea movements and foraging behavior of Australasian gannets (Morus serrator) over three sequential breeding seasons. GPS and tri-axial accelerometer data loggers were used to compare annual variation during incubation and chick rearing at a small colony. The dataset is provided by Parks Australia and was last updated in July 2026.

Use Cases

• Modeling seabird energy expenditure based on vectorial dynamic body acceleration data mentioned in the description
• Analyzing inter-annual foraging trip patterns during different breeding stages (incubation and chick rearing)
• Studying central place foraging strategy constraints within a restricted range as described
• Investigating the relationship between foraging effort and breeding success in years of differing prey abundance

Strengths

• Data collected over three sequential breeding seasons, allowing for inter-annual comparison
• Includes GPS tracking and tri-axial accelerometer data for movement and energy expenditure analysis
• Compares behavior across two distinct breeding stages: incubation and chick rearing

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to a single small colony study
