Range DescriptionColumba bollii occurs on Tenerife (more than 2,000 individuals (Martín and Lorenzo 2001), particularly at Anaga and Teno), La Palma (more than 3,000 birds (Martín and Lorenzo 2001) in a restricted area of the north-east), La Gomera (over 1,000 in Garajonay National Park with some birds outside the park) and El Hierro (where it occupies the whole of Golfo and Sabinosa) in the Canary Islands, Spain. It may formerly have occurred on Gran Canaria, as bones similar to those of a laurel pigeon have been found and there is a possible sight record from the late 19th century. It was common in the past, but disappeared from many areas owing to clearance of laurel forest in the islands. More recently the rate of laurel forest clearance has been slowed or stopped. Population estimates for the species are 1,160-1,315 birds in 1980, 6,000 individuals in 2001, and 5,000-20,000 most recently. Whether these figures reveal genuine population increases is unclear, but the area of occupied territory appears to be expanding and despite several potential threats the population is at least stable, probably increasing.
