Abstract

We describe a non-invasive technique to obtain blood samples from incubating birds without trapping and handling. A larval instar of the blood-sucking bug Dipetalogaster maximus (Heteroptera) was put in a hollowed artificial egg which was placed in a common tern (Sterna hirundo) nest. A gauze-covered hole in the egg allowed the bug to draw blood from the brood patch of breeding adults. We successfully collected 68 blood samples of sufficient amount (median=187 μl). The daily success rate was highest during the early breeding season and averaged 34% for all trials. We could not detect any visible response by the incubating bird to the sting of the bug. This technique allows for non-invasive blood collection from bird species of various sizes without disturbance.
