About 4 pellets contained marsefrial long bones or pelvises or basoccipitals with no teeth. Usually young individuals. Apparently the owls avoid eating the heads? The Eurecorup forms a good pellet by itself and much grass-looking grass seed, maybe sternal contents? This owl roosts within 2 km. of all of our Corrallo traptites. Do rarities associated in the same pellet?
