“…the null model) received slightly more support than models indicating that survival varied with gender and/or age, and substantially more support than models indicating that survival varied across years (Table 2 ). The estimated annual apparent survival from the top model was 0.57 ± 0.03, similar to the estimate of 0.65 from a previous study [ 44 ]. See Additional file 1 : Table S1 for estimates of annual survival from the simple temporal model.…”

“…We colour-banded, monitored, and resighted birds breeding in the Okanagan valley from Penticton (49º 27′ N, 119º 36′ W) to Osoyoos (49º 1′ N, 119º 26′ W) on the USA border, a distance of 66 km between 2001 and 2015. To ensure that resighted individuals were accurately determined, colour combos were confirmed upon multiple observations and by at least two observers (see McKibbin and Bishop [ 23 , 44 ] for details). Birds were sexed and aged (second-year [SY] or after second-year [ASY]) based on plumage characteristics and molt limits [ 24 ]).…”

BackgroundLong-distance migratory birds in North America have undergone precipitous declines over the past half-century. Although the trend is clear, for many migrating species underpinning the exact causes poses a challenge to conservation due to the numerous stressors that they encounter. Climate conditions during all phases of their annual cycle can have important consequences for their survival. Here, using 15 years of capture-recapture dataset, we determined the effects of various climate factors during the breeding, wintering, and migrating stages on the annual survival of a western yellow-breasted chat (Icteria virens auricollis) population breeding in southwestern Canada.ResultsEl Niño effects over the entire annual cycle had little influence on the annual apparent survival of yellow-breasted chats. However, we found evidence that wind conditions during migration, specifically average westerly wind speed or the frequency of storm events, had significant adverse effects on adult annual apparent survival. In comparison, precipitation levels on wintering ground had little to no influence on adult annual apparent survival, whereas growing degree days on the breeding ground had moderate but positive effects.ConclusionsIn the face of climate change and its predicted impacts on climate processes, understanding the influence of weather conditions on the survival of migrating birds can allow appropriate conservation strategies to be adopted for chats and other declining neotropical migrants.Electronic supplementary materialThe online version of this article (doi:10.1186/s12898-017-0139-7) contains supplementary material, which is available to authorized users.

“…An understanding of population processes, including survival and site fidelity, is crucial for effective management of woodland bird populations (McKibbin and Bishop 2012, Belder et al 2018). Survival is a key indicator of the extent to which restoration plantings and woodland remnants are providing suitable habitat for woodland birds.…”

“…If survival is low, habitat patches may be acting as population sinks or ecological traps (Dias 1996, Battin 2004). Site fidelity also provides insights into the relative importance of individual habitat patches for animal populations (McKibbin and Bishop 2012, Meager et al 2018). If site fidelity is high, managers might allocate resources to maintain or improve habitat quality in targeted areas (Lehnen and Rodewald 2009).…”

Woodland birds are a species assemblage of conservation concern, and their persistence in fragmented agricultural landscapes is dependent on both the preservation of existing woodland remnants and the implementation of restoration plantings. However, little is known about the habitat-use and persistence of birds in fragmented agricultural landscapes. We present a detailed, population-oriented study of woodland birds in temperate eucalypt woodland restoration plantings and remnant woodland patches in the Southwest Slopes bioregion of New South Wales, Australia. First, we undertook a 3-yr mark-recapture project to assess annual survival and site fidelity in restoration plantings and woodland remnants. We supplemented our recapture efforts with resightings of color-banded individuals. Second, we tracked individual birds of two species, Superb Fairywren (Malurus cyaneus) and Willie Wagtail (Rhipidura leucophrys), and documented snapshots of their home ranges and movement patterns during the breeding season. Annual survival in the woodland bird assemblage was lower than expected (51%). Home ranges of the Superb Fairywren were positively correlated with patch size, and were constrained by patch edges in linear sites. Superb Fairywrens and Willie Wagtails were more likely to travel longer distances between substrates while foraging in linear sites. Willie Wagtails engaged in significant gap-crossing (up to 400 m) between adjacent habitat patches. Our findings indicate that (1) patch isolation and certain patch configurations place resident birds at an energetic disadvantage, and (2) in our study area, woodland bird populations are continuing to decline. We recommend landscape-scale habitat restoration programs aim to address ongoing population declines. Studies such as ours conducted over longer time periods would provide a deeper understanding of habitat use and population processes of woodland birds in fragmented agricultural landscapes.

Annual survival and breeding dispersal of a migratory passerine, the Scissor-tailed Flycatcher

et al. 2018

Knowledge of survival rates is critical for advancing our understanding of the dynamics of populations and here we report apparent annual survival and breeding dispersal of Scissor-tailed Flycatchers (Tyrannus forficatus) breeding at two sites in southwest Oklahoma (Ft. Sill and Wichita Mountain Wildlife Refuge [WMWR]). Our Cormack-Jolly-Seber estimate of apparent adult survival for the period from 2008 to 2105 was relatively low (0.514) compared to estimates for 36 other migratory and socially monogamous passerines breeding in North America, and was independent of sex (males: N = 151; females: N = 119), breeding status (territory holder or floater), body mass, site, year, and precipitation during the year prior to breeding. Although apparent survival did not differ between sites, dispersal (N = 66 individuals) was more common and breeding dispersal distance (BDD) was greater for Scissor-tailed Flycatchers at Ft. Sill where anthropogenic disturbance was more frequent. BDD also increased with body mass at Ft. Sill (but not at WMWR) and, after accounting for it, BDD at Ft. Sill tended to be greater for birds that failed to breed successfully in the past year. Older birds and males had the longest BDDs at WMWR, and males exhibited a similar tendency at Ft. Sill. We contend that our estimate of apparent survival is low, not because of inherently low survivorship, but, instead, as a consequence of frequent permanent emigration from our population. We also suggest that the greater BDD of older birds (WMWR) and males (both sites) reflects a history of selection for dispersal in response to frequent habitat disturbance. Frequent habitat disturbance, in addition to the opportunity to prospect for territories both before and after breeding, probably enable the earliest spring arrivals (typically older birds and males) to often relocate between years.
