The 2026 report, prepared by SEO/BirdLife and using the same methodology as the 2015 census, analyzes an area of 268.64 hectares through 67 effective listening stations.
The results reflect a general downward trend. The estimated density has decreased from 7.32 birds per hectare in 2015 to 5.24 in 2026. However, the evolution shows differences between neighborhoods, and some areas require specific attention. The study identifies a particularly significant increase in San Miguel, where the estimated density rises from 6.61 to 25.04 birds per hectare. Increases are also recorded in Dumboa (from 3.49 to 9.23), Artia/Arbes (from 1.77 to 5.66), and Azken Portu (from 0.58 to 4.29). Conversely, areas such as the Centro (from 4.71 to 0.91), Pinar (from 25.18 to 11.61), and Santiago (from 11.89 to 2.91) show decreases compared to the previous study.
The objective of the study was to identify, quantify, and estimate the density of urban pigeon populations in Irun and assess the degree of nuisance they may cause. Twelve sampling work sessions were conducted between March and June at 67 stations or areas with a 50-meter radius throughout the city, allowing for the estimation of pigeon abundance and density in the municipality.
The department emphasizes the importance of not feeding the birds, as it can alter their natural behaviors and create a dependency on human-provided food. This practice, although often well-intentioned, can lead to negative consequences for the urban environment and the welfare of the animals themselves. Food scraps can attract other species, promote dirt accumulation, and contribute to pest proliferation.
Therefore, a call is made for citizen collaboration to keep public spaces clean and respect the environmental balance, reminding that caring for animals also involves avoiding habits that may harm them or affect coexistence in the city.
This action stems from one of the winning projects of the 2025 Participatory Budgets and is part of the new work being carried out by the Security and Citizen Coexistence department within the framework of the new animal welfare ordinance, joining other campaigns such as the informative one on various aspects of this regulation (prohibition of feeding in the street, unleashed dogs, etc.).
