Site fidelity and territorial behaviour of some migratory passerine species overwintering in the Mediterranean area
… Phoenicurus ochrurus) were studied at five sites in Spain during winters 1981-84 and 1989-1994. Some birds exhibited winter site fidelity. Recoveries occurred mostly within the same winter of ringing. However, some birds were recorded after 5, 3 and 2 yrs, in the three species respectively, …

Home range, site fidelity, reproductive ecology, and den site characteristics of the San Clemente Island fox
… litters, chronology of reproduction, and den site characteristics. I found that San Clemente Island foxes had home ranges (mean = 0.75 km2, SE = 0.9) and core areas (mean = 0.19 km2, SE = 0.03) 36-116% larger than reported in published studies for other island fox subspecies. Home ranges were …

Site Fidelity and Association Patterns of Bottlenose Dolphins (<i>Tursiops truncatus</i> in the Mississippi Sound
<p>The current study examined the site fidelity and association patterns of a community of 678 wild bottlenose dolphins (Tursiops truncatus) in the Mississippi Sound (Sound) over a three-year period (May 2004 - April 2007). Using photoidentification techniques, 74% (n = 498) of the identified …

Seasonal and Diurnal Behavioral Patterns of Bottlenose Dolphins, <i>Tursiops truncatus</i>, That Exhibit High Site and Low Site Fidelity to Mississippi Sound
… bottlenose dolphins (Tursiops truncatus) exhibit site fidelity to the Mississippi Sound and how the seasonal and diurnal behavioral patterns of dolphins that exhibit high site fidelity to the Mississippi Sound differ from those of dolphins with lower site fidelity. Opportunistic surveys conducted …

Habitat Selection by Yellow -Headed Blackbirds
… birds have the ability to select a breeding site from a large number of sites across a large geographic area. Therefore, one might expect that migratory birds would select the site where they would realize the greatest fitness. However, little is known about how and why migratory birds select …

Winter/Spring Population Characteristics of White-Tailed Deer in an Agricultural/Wetland Complex in Northeastern South Dakota
… restricted core area movement (i.e., 22 ha). Site fidelity was evaluated using multi-response permutation procedures (MRPP) and range-overlap estimates. Site fidelity between years (i.e., intraseasonal site fidelity) and between seasons (i.e., interseasonal site fidelity) on SLNWR was …

The Winter Ecology of the Piping Plover (Charadrius melodus) in Coastal Georgia
… on the conservation significance of this site for the endangered Great Lakes population. During 2003-2004 and 2004-2005, LSSI supported up to 100 Piping Plovers during peak migration, and approximately 40 birds wintered at this site. All populations had similar patterns of arrival, …

Intraspecific variation in environmental and geographic space use: insights from individual movement data
… individual specialisation in geographic space (site fidelity) or in environmental space (environmental specialisation). Applying it to two species of albatrosses, I found evidence of site fidelity but weak environmental specialisation. My results have implications for how limited research …

Head-start Juvenile and Adult Resident Eastern Box Turtles (Terrapene carolina carolina): Winter Ecology Including Microhabitat Selection, Temperature Tolerance and Philopatry
… to assist resource managers in choosing suitable sites for relocation studies, more information on the winter ecology of this species is necessary. We examined the temperature tolerance, microhabitat and degree of philopatry to hibernacula for juvenile and adult E. box turtles for two consecutive …

Demography and Behavior of Western Sandpipers (Calidris mauri) Breeding on the Yukon-Kuskokwim River Delta, Alaska
… annual survival (product of true survival and site fidelity) while correcting for the probability of encounter for 237 males and 296 females. Overall return rates (individual returned to the site in a subsequent season) were lower for females (40%) than males (65%), as was apparent annual …

A population biology of breeding redshanks (Tringa totanus L.)
… of approximately 200 pairs in 1.04km? Mate fidelity was very high, with 71% of surviving pairs remaining faithful. Nest site fidelity was extremely strong for faithful pairs and males with new mates, but significantly weaker for females with new mates. A lower nest site fidelity of young …

The ecology of translocated greater sage-grouse in Strawberry Valley, Utah
… from 2 source populations to a release site in Strawberry Valley, Utah during March-April 2003-2005. The resident population of sage-grouse in Strawberry Valley was approximately 150 breeding birds prior to the release. We radiomarked each female and documented survival, movements, …

The genes must flow: using movement ecology to understand connectivity of Mojave desert tortoise (Gopherus agassizii) populations in altered landscapes
… of data from 950 tortoises), I related long-term site fidelity and dispersal in desert tortoises to intrinsic (size and sex) and extrinsic (seasonal precipitation) covariates. Tortoises display high site fidelity, though this fidelity is altered by seasonal precipitation and sex. Dispersal is more …

Lake Sturgeon (Acipenser fulvescens) Population Attributes, Reproductive Structure, and Distribution in Namakan Reservoir, Minnesota and Ontario
… Distance traveled was lowest (mean=5.3 km) and site fidelity was highest (mean=17.8 days) during winter months. Five females were characterized as potentially reproductive and 14 as non-reproductive based on plasma steroid concentrations. Potentially reproductive females had lower site fidelity …
