Compliance with ethical standards
:
: All applicable international, national and/or institutional guidelines for the care and use of animals were followed. Our study was in accordance with ethical approval from the Spanish ethics committee since eggs were removed before the incubation and the corresponding embryonic development began (RD 53/2013). Capture and manipulation of birds were authorized by the Consejería de Medio Ambiente (Comunidad de Madrid, Spain) under licence from the Spanish institutional authorities (Consejería de Medio Ambiente and Centro de Migración de Aves de SEO/BirdLife). Permission to work in the area was granted by both the Parque Regional de la Cuenca Alta del Manzanares and the Ayuntamiento de Soto del Real, Spain.
