Visual Tracking Data for Four Tern Species in Anglesey, 2009-2010

2009 and 2010 breeding season data for Arctic, common, roseate, and Sandwich terns from the Anglesey Terns Special Protection Area. The data were collected to quantify marine environment usage by these species around their UK breeding colonies. This resource was produced by the Joint Nature Conservation Committee as part of a marine SPA identification programme.

Use Cases

• Modeling tern foraging ranges based on visual tracking data from the breeding colony.
• Analyzing seasonal habitat usage patterns during incubation and chick-rearing periods.
• Informing marine Special Protection Area (SPA) management based on quantified environmental usage.
• Comparing interspecies behavior among Arctic, common, roseate, and Sandwich terns.

Strengths

• Data covers two full breeding seasons (2009 and 2010), including incubation and chick-rearing periods.
• Includes tracking data for four distinct tern species (Arctic, common, roseate, and Sandwich).
• Associated with a formal JNCC report (Report 500) providing analysis context.

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 the single UK Special Protection Area studied.
