The ecology of ectoparasitic species Carnus hemapterus on nestlings of common kestrel (Falco tinnunculus) in Bratislava

The time course and abundance of Carnus hemapterus on common kestrel's nestlings depends on their age and the type of nest. Ectoparasites were found in 97% of nests and the majority of nestlings (83%) were observed to be infested between their 10th and 15th day of life. The highest infestation rate of Carnus hemapterus was recorded on 5- to 10-day old nestlings. We have confirmed that the Carnus hemapterus species feeds on blood; however no negative impact on nestlings and the breeding success of common kestrel was confirmed.
