| Lineage | All birds were caught at the nest site when a partner was present to reduce any risk of leaving the nestlings unguarded. Birds were caught around the ankles with a noose on a telescopic pole. Measurements for weight, bill length and wing length (maximum flattened chord) were taken. GPS (igotU) units weighing ~18 g and measuring 40 x 25 x 9 mm were attached with Tesa tape on the lower back feathers for Imperial Shags and to tail feathers for Rock Shags, knowing (Fijn et al.,2012) that units on the backs of Rock Shags were being removed by the birds. Birds were released in the vicinity of the nest and re-caught 1 ??" 5 days later to recover the GPS device. Dive loggers (CEFAS Technology G5) weighing 2.7 g were placed in conjunction with GPS devices on some individuals by taping to the lower back. In-situ time-lapse cameras (Reconyx HC500) were set up at the colony to monitor the behaviour of handled birds with trackers against neighbouring nests where birds were not handled. Opportunistic regurgitated stomach contents were collected during the handling process when birds voluntarily produced them. Samples were processed in a lab at Stanley on return. Results of the study have been published: S Croft, M Reeves, A Stanworth, N. Ratcliffe, 2014, Tracking Imperial and Rock Shags at two islands (Middle Island and Steeple Jason) at the Falkland Islands. A Summary Report - September 2014, Falklands Conservation. |
