432 is the number of pairs of Audouin’s Gull (Larus audouinii) that have breed in 2019 in San Pedro del Pinatar Saltpans. This are good news considering that last year the colony only raised 180 pairs although it’s still far from the 836 pairs of 2014. Since 2014, Audouins’s Gull population has been decreasing gradually in San Pedro but in 2019 there has been an increasing, being the third year with the highest number of pairs since this species began to breed at San Pedro del Pinatar in 2007.
The colony has been established in two of the embankments near the San Quintín mill in two sub colonies (in different embankments). May 13th was the day on which the largest number of nests was recorded, when 326 and 106 nests were counted in each of the sub colonies. Some asynchrony has been detected between both sub colonies, while the first one was already fully formed on May 2nd, in the second one, 44 new nests were found between May 2nd and 13th, probably because at this colony, birds are younger and no so experienced than the ones of the other sub colony.
