Abstract
Incidental breeding of Robin Erithacus rubecula in Mallorca. First breeding report of the Robin, Erithacus rubecula, in the Balearic Islands. This species is considered a migrant and an abundant winter visitor to these islands. Since 2002 it has been observed during the breeding season at an area known as Son Pax in Palma. In 2004 a maximum of two birds was observed between 30th April and 14th September. On 3rd April 2005 two birds hatched the previous year (EURING code 5) were trapped using mist-nets, one of which was developing an incubation patch (Patch code 1)(PINILLA, 2000). On 16th July a juvenile (EURING code 3) with a brownish head and back, brownish-yellow spots and a red breast was observed at the same place. This confirmed successful breeding of this species in Mallorca and probably for the region
