Abstract


Background. Studying the bird community in urban, semi-urban or agroecosystem anthropic spaces allows us to identify the effects of human disturbance on biodiversity and, thus, design conservation strategies. Objective. To analyzed the structure of the bird community in an anthropized stratum in the center of the state of Veracruz, Mexico, during the spring-summer 2016 season. Methodology. The sampling method was carried out in two strata by plot mapping: the garden plot and the plot agricultural fields were sampled by two observers, between 7:00 and 12:00 h, every 8.6 days on average. Wealth, abundance, seasonality and conservation status of birds were determined. Results. 98 species belonging to 28 families and 14 orders were observed, with the Parulidae family showing the greatest wealth. 54 species were recorded in the gardens and 87 in the agricultural fields, but the indicators predicted up to 70 and 115, respectively, representing 76% of sampling completeness. The Shannon index did not differ significantly between the birds of each stratum, but the rarefaction analysis indicated a wealth of birds significantly higher in the fields than in the gardens. Conclusion. This anthropized landscape it serves as a refuge for seven species at risk.
