ABSTRACT Studying the movement ecology of smaller birds generally implies the use of archival devices, which require retrieval in order to download tracking data. When recapturing fails, archival devices are usually lost and birds carry the devices for longer than necessary. We present a cheap, safe and simple method to detach archival devices from animals in a semi-controlled manner. We used Eco Balloon Ribbon, a water-soluble ribbon, to attach GPS loggers to European Nightjars Caprimulgus europaeus via tail mounts. The ribbon was used as a weak link that dissolved within two minutes after heavy rain. The deployment duration could be estimated by following weather forecasts and the GPS loggers retrieved using a GPS-enabled radio tag. During the course of one breeding season, we deployed 44 GPS loggers and successfully retrieved 39. Here, we share our experience with Eco Balloon Ribbon, describe how to deploy a GPS logger using the tail-mount technique and provide useful tips to increase the success of drop-offs. Our methods can improve the efficacy of tracking studies, reduce the impact on the study species, and facilitate licensing and obtaining fieldwork permissions. Furthermore, we believe that Eco Balloon Ribbon has great potential to serve also in the long-term tracking of wildlife, through its integration as a weak point in collars or harnesses.

ABSTRACT Although colour-ringing is generally considered safe, a small proportion of avian species experience significant ring-related injuries. We report the first description of ring-related injuries in a rhipidurid flycatcher, the Rufous Fantail, and show that, in a population on Rota in the Northern Mariana Islands, switching from plastic to metal rings reduced but did not eliminate ring-related injuries. Over 30% of Rufous Fantails experienced severe injuries (tarsal swelling and leg loss) while wearing plastic rings and 11.7% experienced injuries while wearing metal rings. Injuries were not caused by improper fit of the rings and the use of metal rings in a separate population in Iluka, Australia, did not appear to cause any injuries. We suggest that injuries are caused by the accumulation of spider silk around the tarsus. Rufous Fantails may be more susceptible to injuries on Rota than in Iluka due to the frequency with which they encounter spider webs. We recommend avoiding the use of plastic rings on rhipidurids and related species and, more specifically, developing alternative marking schemes for the potential reintroduction of Rufous Fantails to Guam, where spider webs are abnormally abundant.

ABSTRACT Knowledge of the routes and habitat use of Siberian songbird species during migration is very limited. The goal of our study was to describe the autumnal habitat use of seven Siberian warbler species in the genera Phylloscopus, Acrocephalus, Iduna and Locustella in Far Eastern Russia. A total of 2283 individuals were trapped in mist nets placed within different habitat types between 2012 and 2014 as part of the Amur Bird Project at Muraviovka Park in Far Eastern Russia. We studied the effect of habitat type and vegetation height on the occurrence of each species, and compared our results to published information on habitat use on the breeding grounds. Our results demonstrate that most species exhibit species-specific preferences for habitat type, and that these stopover habitats were similar to habitats used on the breeding grounds.

ABSTRACT The Gannet Morus bassanus is one of the seabirds considered most at risk from collision mortality at offshore wind farms in UK waters, so a better understanding of migration routes informs assessments of risk for different populations. Deployment of geolocators on breeding adults at the Bass Rock, Scotland, and Skrúður, Iceland, showed that the timing of migrations differed between populations, birds from Bass Rock passing south through UK waters mostly in October and back in February while birds from Skrúður passed south through UK waters mostly later, in November, but returned north earlier, in January. Many birds from both colonies made a clockwise loop migration around Britain and Ireland. Only a minority of birds from the Bass Rock returned northwards to the colony through the southern North Sea. A counter-intuitive consequence is that many Gannets moving northwards through waters to the west of Britain and Ireland in spring may be birds from North Sea colonies. Although Gannets normally remain over the sea, one tracked bird appears to have made a short overland passage in spring from the west of Scotland through central Scotland to the Bass Rock, whereas most returned around the north of Scotland.

ABSTRACT Proper ageing of the young birds is crucial in all studies examining age-related characteristics of nestlings and parental effort at the nestling stage. When nests are found after hatching, the age of nestlings cannot be calculated as a time interval from the hatching day: a species-specific guide is needed, but such guides are rarely published. This study describes the post-embryonal development of Reed Warbler nestlings and presents a guide to ageing nestlings of this species. The guide is based on measurements and observations of 354 nestlings of Reed Warblers from 107 nests found during two breeding seasons. We provide a description of developmental events by day, together with nestling drawings, photos and further tables of summarised data. All the traits showed huge variation among the nestlings of the same age, and day-to-day differences in trait values varied throughout the nestling period. We suggest using several traits while ageing this species’ young, especially those that show the most rapid growth at a given stage of development. We also present a simple key to ageing this species’ nestlings.

ABSTRACT Movement-activated camera traps were used at an important moulting site of Canada Goose Branta canadensis and British Greylag Goose Anser anser to test whether a greater number of colour-marked individuals would be identified using camera traps than when only traditional methods were used. Four camera traps were in operation during a 100-day period; in total, 1176 colour-mark sightings were generated representing 159 individually colour-marked geese. The field team made 216 resightings of colour-marked birds during the duration of study, including just five individuals that were not identified using camera traps. During the trial, the camera traps generated more resightings and identified more individual geese than had been found in any previous year of the study. The results highlight the potential for using camera traps as a means to increase resighting rates of colour-marked birds.

ABSTRACT The migratory behaviour of European Song Thrush (Turdus philomelos) populations ranges from resident in the south and west to partly or totally migratory in northern, central and eastern Europe. This varied migratory behaviour could be reflected in morphological adaptations, with migrants having a proportionally longer wing, lower tail:wing ratio, and, if foraging more on fruits, deeper and wider bills. We used data from Song Thrushes captured during the breeding season and in winter in northern Iberia to test for morphological variations between these two periods. In three consecutive years (2014–16), Song Thrushes were captured with mist nests in a region of southern Navarra (Spain) during the breeding season (from May to July) or in the winter period (October to February), during a period of four hours starting at dawn per sampling day. We consider the winter population to be composed of a high proportion of visitors. Breeding Song Thrushes showed proportionally longer tails for given wing lengths, even though wing length did not vary between the two periods. Moreover, winter visitors showed narrower and less deep bills than breeding Song Thrushes. Potential explanations for these results are discussed.
