“…According to previous studies (Caccamise and Hedin 1985;Calvo and Furness 1992;Wilson and Culik 1992), the mass of the fixed device should not exceed 5% of the bird body mass, while Kenward (1987) suggests that even devices constituting 3% might have a negative impact on birds' flight agility. According to Paredes et al (2005) and Harding et al (2009a), data loggers weighing approximately 3.0-3.3% of the bird body mass negatively affected the diving depth and duration, provisioning rates and frequency of foraging trips.…”

We studied the effects of loggers attached to chick-rearing little auks (Alle alle) on their daily time budget (proportion of time spent in the colony and at sea), foraging activity (duration and proportion of long and short foraging flights), chick provisioning rate and their growth and development on Spitsbergen. We found that experimental parent birds performed shorter but more frequent long foraging flights and reduced the frequency of short foraging flights. They spent more time at the colony and reduced chick provisioning rate compared to control birds. Nestlings reared by experimental parents weighed significantly less at their middle, peak and fledging age and departed colony later than chicks of control parents. Little auks depend on energy-rich copepods associated with cold Arctic waters and are expected to face the climate-induced worsening of the foraging conditions, which may have negative impact on their time/energy budget and survival. The study may help to determine the level of extra effort little auks need to invest to breed successfully.

“…The use of bird-borne devices requires an evaluation of possible negative bird reactions and consequent disturbance of marked bird behaviour (Wilson et al, 1986;Wanless et al, 1988;Calvo and Furness, 1992). Severe experimental manipulations may alter the normal sequence of events related to nest attendance and foraging behaviour.…”

SUMMARY: A data logger devised and manufactured by our research team in order to study the homing routes of carrier pigeons was subsequently modified to study the homing behaviour and foraging strategies of breeding marine birds. Recent versions of the data logger, equipped with a flight sensor and depth meter or saltwater switch, were used in a study of the foraging strategies of chick-rearing Balearic shearwaters (Puffinus mauretanicus) in the framework of the project LIFEPuffinus financed by the Balearic Government and the EU. Due to low recapture rates (only 3 out of 6 tagged birds were recovered), only preliminary data from a small sample are available. Data loggers have recorded data on the pattern of nest attendance (including departure time to foraging trips and return time) and the diurnal pattern of flight and dive activity (including depth and duration of dives). Despite the small sample size, the results show that our data loggers can successfully be applied to the study of the breeding biology and foraging ecology-including the diving pattern-of Balearic shearwaters and similar species.Key words: foraging, diving behaviour, breeding biology, Balearic shearwater, Puffinus mauretanicus, data logger. RESUMEN: RESULTADOS PRELIMINARES SOBRE LA ECOLOGÍA TRÓFICA DE LA PARDELA BALEAR PUFFINUS MAURETANICUS A PAR-TIR DE AVES MARCADAS CON DATA-LOGGERS. -Un dispositivo electrónico diseñado y producido por nuestro equipo de investigación con la finalidad de estudiar las rutas de vuelo de palomas mensajeras ha sido adaptado al uso en investigación de la conducta de nidificación y estrategias de alimentación en aves marinas. Versiones mejoradas del aparato, equipado con un sensor de vuelo, y un profundímetro (o bien un sensor de agua marina) se han utilizado para el estudio de las estrategias de alimentación de individuos reproductores de la pardela balear (Puffinus mauretanicus), en el marco del proyecto LIFEPuffinus financiado por el Govern de les Illes Balears y la UE. Disponemos únicamente de datos preliminares, debido al pequeño tamaño de la muestra, ya que sólo se recuperaron tres de los seis aparatos colocados sobre las aves. Los data-loggers han proporcionado información sobre el modelo de permanencia en el nido (incluyendo los horarios de salidas y entradas ), la distribución diaria de las actividades de vuelo y buceo, así como la profundidad y duración de las zambullidas. A pesar del pequeño tamaño de la muestra, nuestros resultados sugieren que este tipo de data loggers puede utilizarse en estudios de conducta de nidificación y alimentación de aves de la talla de la pardela balear, incluyendo el estudio del modelo de buceo.Palabras clave: forrajeo, comportamiento de buceo, biología reproductora, pardela balear, Puffinus mauretanicus, data logger.

“…A growing number of publications show that tracking may come with a cost for the animal, which becomes especially problematic when it affects the measured behaviour (reviewed in [4,13,55,84]). Among the negative effects identified in these reviews are increased mortality, disturbed (migratory) behaviour and reduced reproductive success, eventually resulting in lower fitness.…”

Reduction in adverse effects of tracking devices on waterfowl requires better measuring and reporting

Since the first studies in the mid-twentieth century, lightweight electronic tracking devices have been increasingly used to study waterfowl movements. With half a century of experience and growing sample sizes, it has become clear that the attachment of a tracking device can affect a bird's behaviour and fitness. This becomes problematic when it introduces uncertainty about whether the recorded data represent natural behaviour. Waterfowl may be particularly prone to tag effects, since many species are migratory and tracking devices can disrupt their waterproof plumage. The primary aim of this paper is to identify how tracking devices may affect waterfowl survival, migration and reproduction, and how better measuring and reporting of such effects can improve our understanding of the risks, providing a first step towards reducing their impact in future studies. We reviewed literature on electronic tracking of waterfowl to create an overview of currently recognized effects of harness-attached backpacks, implants, subcutaneous attachments and neck collars. Additionally, we analysed developments in the use of attachment methods, the weight of tracking devices relative to bird body mass, and the reporting rate of effects of tracking devices in 202 original tracking studies. We found that although the number of waterfowl tracking studies described in peer-reviewed literature has steeply increased over the past decades, reporting rates of potential effects have decreased from 65.0 to 26.5%. Meanwhile, the mean weight of the tracking devices relative to the bird's body mass remained stable around 2.0%. Major negative effects were reported in 17% of all studies and were found for all attachment methods. Overall, large differences exist in the occurrence and type of negative effects between species and studies, even if the same tracking methods were used. Inconsistent reporting of effects, lack of control groups to measure effects and incomplete descriptions of the methodology hamper the identification of factors contributing to these effects. To accomplish a reduction in adverse effects of tracking, it is necessary to improve the measuring and reporting of effects. We propose a framework for standardized reporting of methods in primary tracking studies and standardized protocols to measure effects of tracking devices on waterfowl.
