Figure
4: Puffin tracks and associated moult periods. Each plot represents one
individual and their mean moult locations, with a track derived from
each logger. Geolocator positioning accuracy is reduced around the
equinoxes, negatively affecting the latitudinal accuracy of moult
locations, which were all inferred to occur around the equinoxes. The
red dot corresponds to the colony location, Skomer, Wales. Note that
portions of the track apparently crossing land are products of the
inaccuracy of geolocator location estimates around the equinoxes, and
associated smoothing.
Table 2: Metrics for each dual-equipped bird relating to migratory
effort and moult periods. Residencies were described using Lavielle
segmentation of net-sqaured displacement from the colony. Number of
inferred moult periods and time spent in inferred moult altogether are
also shown.
