New and old neighbors of the saltworks

In the present spring of 2020, the breeding community of waterbirds of the Salinas y Arenales de San Pedro del Pinatar Regional Park has increased its diversity. This fantastic news is linked to the installation, for the first time in the saltworks, of a herons breeding colony. In total, 120 pairs of cattle egret (Bubulcus ibis), 7 pairs of little egret (Egretta garzetta) and 3 pairs of black crowned night-heron (Nycticorax nycticorax). The reproductive population of cattle egret and little egret closest to the San Pedro del Pinatar saltworks is Perdiguera Island. On the other hand, since they are nocturnal and isolation nest and small colonies, the black crowned night-heron breeding areas are unknows, generally nesting in trees on the Mar Menor associated wetlands.

However, other specie arouses special interest in this colony, the glossy ibis (Plegadis falcinellus). The four pairs detected in the saltworks represent the first breeding record in Murcia. This species, extinct in Spain at the beginning of the 20th century, resumed its breeding in 1993 in Valencia, since then it has grown progressively in the south and east of the iberian peninsula.

Also is noteworthy the return of the slender-billed gull (Chroicocephalus genei) as a breeder in the Regional Park. Until now, this species had nested in the saltworks during the 2010-2012 period, reaching a maximum of 78 breeding pairs.
