“…While we are unable to disentangle the effects of animal handling from the effects related solely to GPS collars themselves, we illustrate that significant effects in behavior, activity, and FGMs dissipate quickly after animals are fitted with a GPS collar. We encourage further investigation into the long-term effects of these revolutionary devices to the field of movement ecology, but concur with similar studies ([14–17,37,78]) that find no evidence that should preclude their use.…”

“…Accelerometry data showed that headshaking declined in magnitude by half every 4 hours after GPS collar fitting, pinpointing the time it takes for collaring effects to subside. In addition to the valuable information provided to wildlife researchers, these data should also assist in the ongoing discussion with the general public, providing quantitative information on the time it takes for animals to adjust to being fitted with tracking devices (see also [13–17,37]). Although our sample sizes are small, our results were consistent across individuals monitored and are the first to quantify the time it takes for headshaking to return to normal levels after GPS collaring fitting.…”

“…Since the inception of animal tracking, scientists have recognized the ethical concerns of fitting animals with tracking devices, providing general guidelines (e.g., devices should weigh <5% of total animal body weight) and in most cases, requiring tracking studies to undergo a thorough review from animal care and use committees before being initiated [11]. While various studies investigating potential adverse effects resulting from animals wearing telemetry devices exist (for a review, see [12]), most mammalian studies (∼85% reported in [12]) have focused on small-to medium-sized animals (< 15 kg), which are easier (and less expensive) to monitor and manipulate in laboratory settings than studies on large animals (although see [13–17]). Prevailing results of these studies illustrate that the effects of fitting tracking devices on animals are generally minimal, although severe and study-specific impacts have been reported [12, 18].…”

28GPS collars have revolutionized the field of animal ecology, providing detailed information on 29 animal movement and the habitats necessary for species survival. GPS collars also have the 30 potential to cause adverse effects ranging from mild irritation to severe tissue damage, reduced 31 fitness, and death. The impact of GPS collars on the behavior, stress, or activity, however, have 32 rarely been tested on study species prior to release. The objective of our study was to provide a 33 comprehensive assessment of the short-term effects of GPS collars fitted on scimitar-horned oryx 34 (Oryx dammah), an extinct-in-the-wild antelope once widely distributed across Sahelian 35 grasslands in North Africa. We conducted behavioral observations, assessed fecal glucocorticoid 36 metabolites (FGM), and evaluated high-resolution data from tri-axial accelerometers. Using a 37 series of non-standard regression models, we illustrate clear but short-term effects to animals 38 fitted with GPS collars. Behavioral observations highlighted a significant increase in the amount 39 of headshaking from pre-treatment levels, returning below baseline levels during the post-40 treatment period (>3 days post-collaring). Similarly, FGM concentrations (i.e., stress hormones) 41 increased after GPS collars were fitted on animals but returned to pre-collaring levels within 5 42 days of collaring. Lastly, tri-axial accelerometers, collecting data at eight positions per second, 43 indicated a > 480 percent increase in the amount of hourly headshaking immediately after 44 collaring. This post-collaring increase in headshaking was estimated to decline in magnitude 45 within 4 hours after GPS collar fitting. These effects constitute a handling and/or habituation 46 response (model dependent), with animals showing short-term responses in activity, behavior, 47 and stress that dissipated within several hours to several days of being fitted with GPS collars. 48Importantly, none of our analyses indicated any long-term effects that would have more pressing 49 animal welfare concerns. 3 | Stabach et al. 3 50 51 52 Global Positioning System (GPS) devices have revolutionized the field of animal ecology [1-3], 53 providing detailed information about how animals move and utilize space across diverse and 54 often rapidly changing landscapes [e.g., 4-7]. A variety of taxa can now be monitored, ranging 55 in size from pint-sized ovenbirds (Seiurus aurocapilla; [8]) to multi-ton elephants (Loxodonta 56 africana; e.g., [9]). In some instances, animals are now being monitored over their entire 57 lifespans [10], a result of technological innovations (e.g., solar rechargeable batteries) or re-58 tagging efforts, and at temporal resolutions (minutes to seconds) that would have been 59 unimaginable just a few decades ago. 60Since the inception of animal tracking, scientists have recognized the ethical concerns of 61 fitting animals with tracking devices, providing general guidelines (e.g., devices should weigh 62 <5% of total animal body weight) and in most ca...

We conducted behavioral observations, assessed fecal glucocorticoid metabolites (FGM), and evaluated high-resolution data from tri-axial accelerometers. Using a series of datasets and methodologies, we illustrate clear but short-term effects to animals fitted with GPS collars from two separate manufacturers (Advanced Telemetry Systems-G2110E; Vectronic Aerospace-Vertex Plus). Behavioral observations highlighted a significant increase in the amount of headshaking from pretreatment levels, returning below baseline levels during the post-treatment period (>3 days post-collaring). Similarly, FGM concentrations increased after GPS collars were fitted on animals but returned to pre-collaring levels within 5 days of collaring. Lastly, tri-axial accelerometers, collecting data at eight positions per second, indicated a > 480 percent increase in the amount of hourly headshaking immediately after collaring.

Importantly, none of our analyses indicated any long-term effects that would have more pressing animal welfare concerns.

Resting is a crucial daily requirement for all animals. It serves various purposes such as energy conservation (Glass et al., 2021;Riede et al., 2017), thermoregulation (Lutermann et al., 2010, and predator avoidance (Lima et al., 2005). Additionally, rest encompasses sleep, which is essential for neuro-physiological homeostasis (Freiberg, 2020;Schmidt, 2014). To meet physiological requirements and integrate ecological constraints, such as predation risk, animals allocate a significant proportion-often more than half-of their daily time budget to resting, which takes place at specific resting
