Abstract:

A thorough review of the records of Little Crakes in Spain (Peninsular Spain, Balearic Islands and Canary Islands) shows that, contrary to previous assumptions, there are no firm data supporting the regular breeding or wintering of this species in Spain. Although there is a confirmed breeding record, as well as sporadic records of birds during both winter and summer, the species is mainly seen during migration and very rarely. Only along the north-eastern coast of the Iberian Peninsula (Catalonia and Valencia regions) is it recorded on a regular basis annually, although in very low numbers. In the rest of the Peninsula and on the Islands, it seems to be rare or very rare. Spring migration extends from the end of February until May, with peak movements in March-April. The autumn migration is much less apparent and appears to take place between August and December, with maximum intensity in October-November. Spring migration dates appear quite early when compared with those published for France and central Europe, while those for autumn migration are delayed. These differences suggest migratory movements with long resting periods. Because of the scarcity of the species and the comparative difficulties of a correct identification, which raise doubts about several published records, it may be recommended that future records should be examined by the Spanish Rare Birds Committee.
