Resumen de A pair of Serins (Serinus serinus) attacking a Magpie (Pica pica) close to their nest
Juan Carlos Senar, D. Boné, L.A. Boné
Ctive parental antipredator stratigies in ehich either of the parents attacks a potential predator to defend the nest have been rarely described for cardueline finches. Here we describe how, on 10 August 1996, a parie of Serins dive-attacked a Magpie for at least 40 m. We found a Serin nest with one fledgling was 20 cm from the nest and was observed to start. The fledgling was 20 cm from the nest and was fully growna and the almost non-existent renesting potential of the pair (observation in mid-August) could have enhanced the reproductive value of the fledgling, making such defence beneficial to both parents and offspring.
