Nocturnal Activity of Insect Fauna in Osprey Nests: Insights from Video-cameras

Still frames from video recordings showing (a) a female Osprey incubating at night and partially covered by dermestid larvae, and (b) details of the nest surface as well as the tail feathers of a nestling covered by the larvae; ectoparasite larvae are identified by white circles. (c) Lateral and ventral images of a dermestid larva collected in one of the nests (examination of the larvae was accomplished using an Optika SZM-2 stereo-binocular microscope; photos were made using a Canon 760D digital camera equipped with a Canon MPE-65 lens and mounted on Manfrotto micro-slider movement system; images were then processed with Zerene Stacker software). (d) Young Osprey nestling affected by dermestid larvae and (e) enlargement of the nestling's abdominal lesion.
