transitions

Contains raw data on sunset and sunrise times (so called 'transitions') used to estimate longitude, movement and stationary periods. The file shows data of 27 solar geolocator-loggers deployed on pied flycatchers, Ficedula hypoleuca, in Drenthe The Netherlands (Longitude: 6.378, Latitude: 52.820) in 2013, using Intigeo-W50 made by Migrate Technology Ltd logger. Data was processed using the program BASTrack

return_in_2014

Observed local return in 2014 of pied flycatchers with and without geolocator devices in 2013, based on field observations and catches. This file is used to study potential effects of geolocator deployment and harness types on the survival of pied flycatchers, compared to birds without these devices

timing_in 2013-2014

Timing of breeding arrival dates (in males and females) and first egg laying dates (females) in 2013 and 2014 in Drenthe (The Netherlands), as shown for pied flycatchers deployed with geolocator devices in 2013 or without such devices. Arrival and egg laying are based on field observations. This file is used to study potential effects of geolocator deployment and harness types on the timing of arrival and egg laying of pied flycatchers, compared to birds without these devices. Timing is expressed as days relative to the sex-specific annual mean of the population

Effect of translocation on the interval between female arrival and laying date in pied flycatchers.

<p>Interval between arrival date of females in the original breeding area and first egg date was used. Translocated nests: open circles and dashed regression lines. Control nests: filled circles and solid regression lines.</p

Effect of translocation on the correlation between laying date and clutch size in pied flycatchers.

<p>First egg date was used as laying date. For graphical reasons only, original data points were shifted 0.05 lower (control) or 0.05 higher (translocated) along the y-axis. Regression lines were calculated from original data.</p
