On the 15th of June, the first chicken of a captive pair on Fuerteventura was born at the Biological Station of the Oliva (Cabildo of Fuerteventura). The parents consist of two irrecoverable birds that are at the biological station since 2009. This year the couple produced two clutches (one egg in both cases), one on March 24 that failed at an early embryonic stage, and a second clutch, on May 2, that hatched successfully after 45 days of artificial incubation.
There are currently two pairs held in captivity, one in Fuerteventura, the other in Gran Canaria. Both pairs laid regularly eggs in the past, but very rarely these eggs ultimately resulted in fledglings. This happened once in Gran Canaria (2013: ‘Tamaran’, 3NP), and the bird was released and fitted with a GPS tag. 3NP seems perfectly integrated in the currently population and behaves seemingly normal.
