Seabird Counts at Pound Nets with Looming-Eye Buoy Experiment, 2021

Bird count data from a 46-day field experiment testing the effect of looming-eye buoys on seabird depredation at two pound net sites. The dataset includes 80 observations of four piscivorous bird species, collected between April and June 2021. Supplementary material for the study was authored by Gildas Glemarec and is shared under a CC-BY-4.0 license.

Use Cases

• Modeling the temporal effect of a deterrent device based on repeated daily counts.
• Comparing bird depredation rates between a treatment and control site.
• Analyzing species-specific responses to a visual deterrent for large piscivorous birds.

Strengths

• Experimental design includes a control site spaced 1200 meters from the test site.
• Data collection was structured over 46 days with 80 total observations.
• Statistical analysis is detailed, using Generalized Additive Models (GAM) for three different bird groupings.

Limitations

• Row and column counts are unknown, limiting suitability assessment.
• Observer effects could not be estimated as each net was observed by only one person per day.
• The dataset is small at 646.5 KB, indicating limited scope.
