“…We therefore calculated monthly home range size by first estimating h ref with the Home Range Tools for ArcGIS (Rodgers et al 2005 ) and then using Hawth's Analysis Tools for ArcGIS (Beyer 2005 ) to calculate 99% fixed-kernel monthly home ranges with a grid cell size of 100 m. We elected to use an ad hoc parameter ( h adhoc ) to choose the smallest increment of h ref that resulted in a contiguous 99% kernel polygon (i.e. 0.3* h ref = h adhoc ) which can be used previously as an alternative method to h lscv which often fails with clustered GPS location data (Berger andGese 2007 , Cline andHaig 2011 ).…”

Condors and vultures comprise the only group of terrestrial vertebrates in the world that are obligate scavengers, and these species move widely to locate ephemeral, unpredictable, and patchilydistributed food resources. In this study, we used high-resolution GPS location data to quantify monthly home range size of the critically endangered California Condor Gymnogyps californianus throughout the annual cycle in California. We assessed whether individual-level characteristics (age, sex and breeding status) and factors related to endangered species recovery program efforts (rearing method, release site) were linked to variation in monthly home range size. We found that monthly home range size varied across the annual cycle, with the largest monthly home ranges observed during late summer and early fall (July-October), a pattern that may be linked to seasonal changes in thermals that facilitate movement. Monthly home ranges of adults were significantly larger than those of immatures, but males and females used monthly home ranges of similar size throughout the year and breeding adults did not differ from non-breeding adults in their average monthly home range size. Individuals from each of three release sites differed significantly in the size of their monthly home ranges, and no differences in monthly home range size were detected between condors reared under captive conditions relative to those reared in the wild. Our study provides an important foundation for understanding the movement ecology of the California Condor and it highlights the importance of seasonal variation in space use for effective conservation planning for this critically endangered species.

“…In contrast to recent studies that have focused primarily on nesting habitat and site occupancy during the breeding season (Bolenbaugh, Cooper, Brady, Willard, & Krementz, 2012;Darrah & Krementz, 2009;Valente, King, & Wilson, 2011), our study investigated the intra-and interseasonal movements of king rails at one site on the Atlantic coast. Our approach was to examine habitat use of king rails on an annual cycle, as single-season approaches cannot effectively identify an animal's spatial requirements to the extent necessary for developing conservation plans (Cline & Haig, 2011).…”

Seasonal home range dynamics and sex differences in habitat use in a threatened, coastal marsh bird

A comprehensive understanding of spatiotemporal ecology is needed to develop conservation strategies for declining species. The king rail (Rallus elegans) is a secretive marsh bird whose range historically extended across the eastern United States. Inland migratory populations have been greatly reduced with most remaining populations inhabiting the coastal margins. Our objectives were to determine the migratory status of breeding king rails on the mid‐Atlantic coast and to characterize home range size, seasonal patterns of movement, and habitat use. Using radiotelemetry, we tracked individual king rails among seasons, and established that at least a segment of this breeding population is resident. Mean (±SE) home range size was 19.8 ± 5.0 ha (95% kernel density) or 2.5 ± 0.9 (50% kernel density). We detected seasonal variation and sex differences in home range size and habitat use. In the nonbreeding season, resident male home ranges coincided essentially with their breeding territories. Overwintering males were more likely than females to be found in natural emergent marsh with a greater area of open water. Females tended to have larger home ranges than males during the nonbreeding season. We report for the first time the use of wooded natural marsh by overwintering females. Brood‐rearing king rails led their young considerable distances away from their nests (average maximum distance: ~600 ± 200 m) and used both wooded natural and impounded marsh. King rails moved between natural marsh and managed impoundments during all life stages, but the proximity of these habitat types particularly benefitted brood‐rearing parents seeking foraging areas with shallower water in proximity to cover. Our results demonstrate the importance of interspersion of habitat types to support resident breeders. Summer draining of impounded wetlands that are seasonally flooded for wintering waterfowl allows regrowth of vegetation and provides additional habitat at a critical time for wading birds.

“…This difference in behaviour can also explain the sexual differences found in the relative size of the sternum and shape of the wingtip. Other contributing factors to the observed sexual size dimorphism could include diet, habits, habitat use and migration between males and females (Green et al 1990, Green 1991, Devort 1997, McCloskey & Thompson 2000, McCloskey et al 2009, Cline & Haig 2011.…”
