“…This may have occurred particularly along coastlines with a year‐round temperate climate as is the case for the two remaining Moroccan populations or the release population in Andalusia (Serra et al ., ; Lopez & Quevedo, ). A similar situation has been recorded in other migratory species, such as White stork (Shephard et al ., ). The remaining Northern bald ibis colonies at the Atlantic coast in Morocco are sedentary and, therefore, none of the individuals in the wild migrate.…”

From the perspective of zoological institutions reintroduction projects offer many possibilities to link conservation and research programmes. An example of the multi‐layered and diverse contributions that zoological institutions in general and, specifically, Vienna Zoo, Austria, can make is the reintroduction of the Northern bald ibis Geronticus eremita in central Europe. The involvement of zoological institutions ranges from the provision of eggs or birds for release trials, to financial and advocacy support, including with government agencies and non‐governmental organizations. Through involvement at a steering level at the coordinative association ‘Förderverein Waldrappteam’ and as a partner in the EU LIFE+ reintroduction project, Vienna Zoo directly contributes to the shape of the reintroduction project for this Critically Endangered species, and provides much more than technical and infrastructural support. The reintroduction of the Northern bald ibis is broadly in line with the reintroduction guidelines of the International Union for Conservation of Nature. This project provides added benefits not only through its work to prevent the illegal hunting of migratory birds but also the production and dissemination of scientific research.

“…Many species exhibit distinct movement patterns for different behavioral states in response to fluctuating resource availability, sociality, mating and breeding requirements, and altered environments [9,[47][48][49]. Some white ibis in Florida clearly exhibited such movement patterns in response to variability in the timing and location of resources and their innate behavioral plasticity, leading to nomadic movements similar to other species [4,50,51].…”

“…Without direct knowledge of an animal's behavior, seasons for a given species are typically defined based on calendar date or relationships with biotic (e.g., vegetation phenology) or abiotic (e.g., wet-dry cycles) factors derived from observational data. However, spatial, temporal, and individual variation can all reduce the accuracy of seasons derived from climatic factors and historical records alone [2,3,8,9]. For example, many environmental cues, such as spring greenup and wetland water depths, vary across latitudinal gradients and also temporally; this can result in some populations of the same species transitioning between different behavioral states at different times [6,10].…”

Additionally, due to fluctuations in resource availability amongst land-use types (i.e., human-altered versus unaltered), individuals living in urban areas can vary in their seasonality and exhibit different behaviors from those living in unaltered areas such as: reduced site fidelity, reduced range size, abandoned migratory movements, or year-round breeding [3,5,9,[11][12][13][14].…”

The movements of a recently urbanized wading bird reveal changes in season timing and length related to resource use

et al. 2020

The American White Ibis (Eudocimus albus) is a nomadic wading bird that is increasing the amount of time spent foraging in urban areas, relying on artificial wetlands and other anthropogenic resources year-round. In this study, we explore whether and how American White Ibis association with urban environments is predictive of variation in the timing and length of behavioral seasons. Other urbanized species exhibit altered annual cycles such as loss of migratory behavior and year-round breeding related to consistent resource abundance, often related to intentional and unintentional provisioning. To determine if these same patterns of behavior were also present in White Ibis, we used behavioral change point analysis to segment the tracks of 41 ibis equipped with GPS backpacks to identify the initiation and duration of four behavioral seasons (non-breeding, pre-breeding, breeding, post-breeding) the degree of urban association. We found that intraspecific variation in urban habitat use had strong carryover effects on the timing and duration of behavioral seasons. This study revealed ibis with higher use of urban habitats in non-breeding seasons had longer nonbreeding seasons and shorter breeding seasons that began earlier in the year compared to ibis that primarily use wetland habitats. The timing and duration of seasons also varied with ibis age, such that ibis spent more time engaged in breeding-related seasons as they aged. Juvenile and subadult ibis, though considered to be reproductively immature, also exhibit behavioral shifts in relation to breeding seasons. The behavioral patterns found in this study provide evidence that ibis are adapting their annual cycles and seasonal behaviors to exploit urban resources. Future research is needed to identify the effect of interactions between ibis urban association and age on behavioral season expression.Murray MH, Adams HC, Ellison TJ, Yabsley MJ, Hernandez SM (2020) Data from: The movements of a recently urbanized wading bird reveal changes in season timing and length related to resource use.

“…Given the cost and difficulty of tagging and the benefits of monitoring individuals throughout their annual cycle (Marra et al 2015), the use of backpack-mounted solar-powered GPS platform transmitter terminals (PTTs) is popular, due to device longevity (Mueller et al 2013;Shephard et al 2015;Mahood et al 2016) and the long retention of backpack harnesses (Steenhof et al 2006). Impacts of backpacks may arise from increased energy expenditure through the additional weight (Barron et al 2010), loss of aerodynamics (Vandenabeele et al 2014) or clinical issues related to the harness, such as soft tissue injuries and subsequent infections (Peniche et al 2011;Michael et al 2013).…”

Backpack-mounted satellite transmitters do not affect reproductive performance in a migratory bustard

Backpack-mounted satellite transmitters (PTTs) are used extensively in the study of avian habitat use and of the movements and demography of medium-to large-bodied species, but can affect individuals' performance and fitness. Transparent assessment of potential transmitter effects is important for both ethical accountability and confidence in, or adjustment to, life history parameter estimates. We assessed the influence of transmitters on seven reproductive parameters in Asian houbara Chlamydotis macqueenii, comparing 114 nests of 38 females carrying PTTs to 184 nests of untagged birds (non-PTT) over seven breeding seasons (2012)(2013)(2014)(2015)(2016)(2017)(2018) in Uzbekistan. There was no evidence of any influence of PTTs on: lay date (non-PTT x ̅ = 91.7 Julian day ± 12.3 SD; PTT x ̅ = 95.1 Julian day ± 15.7 SD); clutch size (non-PTT x ̅ = 3.30 ± 0.68 SD; PTT x ̅ = 3.25 ± 0.65 SD); mean egg weight at laying (non-PTT x ̅ = 66.1 g ± 5.4 SD; PTT x ̅ = 66.4 g ± 5.4 SD); nest success (non-PTT x ̅ = 57.08% ± 4.3 SE; PTT x ̅ = 58.24% ± 4.5 SE for nests started 2 April); egg hatchability (non-PTT x ̅ = 88.3% ± 2.2 SE; PTT x ̅ = 88.3% ± 2.6 SE); or chick survival to fledging from broods that had at least one surviving chick (non-PTT x ̅ = 63.4% ± 4.2 SE; PTT x ̅ = 64.4% ± 4.7 SE). High nesting propensity (97.3% year −1 ± 1.9% SE) of tagged birds indicated minimal PTT effect on breeding probability. These findings show that harness-mounted transmitters can give unbiased measures of demographic parameters of this species, and are relevant to other large-bodied, cursorial, ground-nesting birds of open habitats, particularly other bustards.
