Spanish Sparrow Passer hispaniolensis

Having arrived on the island of Olib (UTM VK81) on 29 May 2007, we saw the first Spanish Sparrow Passer hispaniolensis no later than on 31 May. At around 7.00 hrs, a male was spotted on a rooftop, about 100 m from the harbour, and a little while later another specimen was seen, 300 m from the location of the first occurrence. Between 1-3 Jun, we stayed on the nearby island of Silba. There, only House Sparrows Passer domesticus were seen breeding (10-15 pairs), and no Spanish Sparrows were observed, despite repeated search. On 4 Jun, we returned to the island of Olib, where we succeeded again in observing male Spanish Sparrow at two different localities: on houses near the harbour and on the building of the school. On 4 and 5 Jun we attempted to make a census on the Olib sparrows, and found that the number of nesting pairs was possibly 1-2 pairs of Spanish Sparrows and about 25-30 pairs of House Sparrows
