Data from: African departure rather than migration speed determines variation in spring arrival in pied flycatchers

Dataset

Description

The data package contains three datasets:
- 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.

- 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.
