RESUMO
The prevalence, intensity and abundance of acuaroid nematodes were determined in the common kestrel (Falco tinnunculus) in Andalusia, Spain. Acuaroid nematodes were present in 26/41 (63.4%) of birds examined. The most common species belonged to the genus Synhimantus subgenus Synhimantus (56%): S. (S.) laticeps (36.5%), S. (S.) robertdollfusi (24.3%) and a single specimen of a third, unknown, Synhimantus (S.) spp., unlike any other described previously (2.4%). Other species identified were Synhimantus (Dispharynx) spp. (2.4%), S. (D.) nasuta (4.8%), Desportesius spinulatus (9.7%) and Skrjabinoclava spp. (2.4%). This is the first record of these three species in F. tinnunculus, but the latter two are considered to be accidental parasites in birds of prey.
