“…The weight percentage (W%) was estimated as the total weight of each prey taxon divided by the combined estimated total weight of all prey taxa, multiplied by 100. The index of relative importance was calculated as: IRI = (N% + W%) FO%, where N% = numerical percentage, W% = weight percentage, and FO% = percentage of frequency of occurrence ( Martin, Twigg & Robinson, 1996 ; Hart, Calver & Dickman, 2002 ; Marti, Bechard & Jaksic, 2007 ; Santana et al, 2019 ; Muñoz-Pedreros & Rau, 2020 ; Rocha, Branco & Barnilli, 2021 ). The IRI was divided by the total IRI, then multiplied by 100 to obtain the percent IRI (IRI%).…”

“…(Carrete & Tella, 2017). Así mismo, utiliza para nidificar, en todo su rango de distribución, áreas abiertas sin árboles cercanos, típicamente zonas donde existen herbívoros que mantienen el pasto corto y mamíferos excavadores que, además de pastar, construyen madrigueras que luego las lechuzas utilizan para ellas (Borsellino, 2017;Rocha et al, 2021).…”
