We investigated the reliability of buccal swabs for molecular sex determination in very young nestlings (0–14 days old) and adults of the Common Swift (Apus apus) compared to the results from blood samples of the same individuals. Sex determination based on buccal swabs matched the result of sex determination based on blood samples in 46 out of 47 nestlings(More)
The effects of predation on Common Redshanks Tringa totanus incubation patterns and behaviour was investigated in 2006 and 2007 at three mainland study sites at the Jadebusen and at one study site on the island Wangerooge, Wadden Sea National Park Lower Saxony (Germany), using temperature data loggers. At these sites, breeding Redshanks were naturally(More)
The use of haematophagous bugs (Triatominae) for minimally-invasive blood sampling has increasingly gained interest. We developed a small bug-containing dummy egg (size: 25 × 19 [mm]) for stress-free blood sampling during incubation in Common Swifts (Apus apus) and potentially even smaller bird species. Our design expands on an application of a method(More)
