El cernícalo primilla es una especie que nidifíca en densas colonias en construcciones humanas. En esta especie es conocida la conducta aloparental cuando los pollos de cierta edad pueden moverse hasta otros nidos donde se camnuflan entre los pollos del mismo y son alimentados por adultos no emparentados genéticamente con ellos. Aqul describimos una conducta diferente de cuidado aloparental, de una hembra de primer año alimentando pollos en dos nidos, uno propio y otro ajeno. Los analisis de DNA multilocus fingerprinting revelan que no existe parentesco genético entre dicha hembra y los pollos o los adultos del nido ajeno. Se revisan las distintas hipótesis que pueden explicar este caso de cuidado aloparental. Se sugire que bajo ciertas circunstancias, los pollos pueden manipular el cuidado aloparental incluso desde sus propios nidos.
The study was carried out while J. Aparicio and P Cordero were ascribed to Direccion General Investigacion Cientifica y Tecnica (DGICYT) (PB94-0070). This project financed the stay of P. Cordero at Nottingham where the analyses of DNA multilocus fingerprinting were done. Also, later ascriptions were DGICYT (PB97-1249) to P. Cordero and DGICYT (PB97-1233) to J. Aparacio.
