No longer fledglings but struggling to fly: peer support workers' experiences of forming an occupational identity within an urban NHS trust: an interpretative phenomenological analysis
Background: Mental health policy promoting the notion of self-management and the patient as the expert welcomed the advent of peer support (Watson, 2017; Gillard, 2019), which is now regarded as the fastest growing profession within mental health services (Rebeiro Gruhl et al., 2016). Research has …

Post-fledging ecology of an endangered species: The golden-cheeked warbler
… Golden-cheeked Warbler (Setophaga chrysoparia) fledglings in Texas. I monitored nests until fledging and tracked fledglings for at least four weeks after leaving the nest. I estimated survival rates for fledglings during the first four weeks out of the nest, analyzed how habitat and behavioral …

Pre- to post-fledging carryover effects and the post-fledging ecology of the Dickcissel (Spiza americana)
… mortality (predation and exposure) of fledglings? (3)What is the relative influence of body condition and wing development on cause-specific mortality of fledglings compared to other potential factors? (4) What post-fledging micro-habitat characteristics do fledglings prefer to use? (5) …

Investigation of the impact of fur seals on the conversation status of seabirds at islands off South Africa and the the Prince Edward Islands
… killed some 6 000 Cape gannet Morus capensis fledglings around Malgas Island in the 2000/01 breeding season, 11 000 in 2003/04 and 10 000 in 2005/06. This amounted to an estimated 29%, 83% and 57% of the overall production of fledglings at the island in these breeding seasons respectively. …

Niche segregation among three sympatric species of swallows in southern Ontario
… diet. To determine post-fledging movements, fledglings were tracked using automated telemetry.Cliff Swallow fledglings differed from the other two species in their post-fledging residency time at the natal site. This information may help to identify potential factors contributing to …

Premigratory movements of a long-distance migratory species: the Wood Thrush (Hylocichla mustelina)
… Base, Quantico, Virginia (38 30' N, 77 25' W). Fledglings became independent 0 0from their parents at 28-36 days post hatching and dispersed 307-5300 m from their natalsites to join flocks of conspecifics. About half (46%) of the young birds stayed in onedispersal site until migrating, but the …

Breeding Behavior and Reproductive Success of Chipping Sparrows in Northwestern Minnesota
… Males assumed nearly all care of first brood fledglings, freeing the female to build a second nest. This strategy of parental care may improve the chances of a pair having a second brood.</p><p>Pair relationships were typically monogamous. One of 32 males was polygynous. Increased male singing …

Female Dispersal and Inbreeding in the Red-cockaded Woodpecker
… as well as lower survival and recruitment of fledglings than unrelated pairs. Moderately related pairs (kinship coefficient between 0 and 0.1) and moderately inbred individuals had increased hatching success, but did not produce more young. Despite documented costs of close inbreeding and a …

Factors affecting loggerhead shrike mortality in Virginia
… soil areas and medium grass. I radio-harnessed fledglings at a mean age of 56 days to document dispersal, fall home-range areas, and survival rates. During the postfledging dispersal period, survival rates were 100% fledglings dispersed at a minimum of 78 days of age, and fall home-ranges …

The role of fruit colour in avian fruit selection: an objective approach
… are cues for food recognition in migrants or fledglings. 2. Fruit colours correlate with chemical compounds. 3. Fruit colours serve as advertisement for ripe fruits. Reflectance spectra are the most objective colour assessment currently possible. Birds show no colour preference, naive …

Ecology and conservation of the Såli (Micronesian Starling, Aplonis opaca) in the presence of the invasive Brown Treesnake (Boiga irregularis) in Guam, Mariana Islands
… Såli adults appear to have high survival, their fledglings are highly vulnerable to predators. My research focused on refining our understanding of how BTS are impacting Såli ecology and survival, and how BTS management can benefit Såli conservation. In my first chapter, I conducted the first …

Population demography of lark buntings: post-fledging survival, fecundity, and breeding decisions
… using radio-telemetry and color bands to track fledglings. For 2001-2002 data, I employed the joint model in program MARK to examine the effects of drought condition, time in season, age, nestling condition (rank, condition index, or brood size), mark type (radio-marked versus band-only), and …

Investigating the causes of the decline of the urban house sparrow Passer domesticus population in Britain
… first 10 days after fledging (57% for suburban fledglings, compared to 70% for rural fledglings). The combined effects of lower annual productivity and lower predicted post-fledging survival in suburban localities were large enough to result in rapid predicted population decline, given plausible …

Reproductive success of a generalist brood parasite predicts the rate of parasitism in the subsequent year
… cowbird eggs, and the number of host and cowbird fledglings for 3848 warbler nests from 1994-2010 in southern Illinois. Data were analyzed using a generalized linear mixed model (GLMM) with binomial distribution. We accounted for variation in site, nest box, identity of female warbler, and year in …

The ecology of the Manx shearwater Puffinus Puffinus on Rhum, West Scotland
… in provisioning chicks late in the season. Heavy fledglings are apparently more likely to survive than light ones so that there is selective advantage in breeding as early as possible. The ultimate and proximate control of timing of laying is discussed. There was evidence of year to year variation …
