“…Recent netting studies within clearcuts in eastern deciduous forest have expanded the list of forest-breeding species that appear to use second-growth vegetation in late summer, but these studies did not show if such habitats were required by these species (Marshall et al 2003, King et al 2006, Vitz and Rodewald 2006; J. Faaborg, P. A. Porneluzi, R. Brito-Aguilar, and R. L. Clawson, unpublished manuscript). These post-breeding habitats may be critical to both the juvenile and adult survival components of breeding-season fitness, but they have not been studied in depth (Ahlering andFaaborg 2006, Whittaker andMarzluff 2009).…”

Abstract. Our understanding of migratory birds' year-round ecology and evolution remains patchy despite recent fundamental advances. Periodic reviews focus future research and inform conservation and management; here, we take advantage of our combined experiences working on Western Hemisphere avian migration systems to highlight recent lessons and critical gaps in knowledge. Among topics discussed are: (1) The pipeline from pure to applied researchers leaves room for improvement. (2) Population limitation and regulation includes both seasonal and between-season interactions. (3) The study of movements of small-bodied species remains a major research frontier. (4) We must increase our understanding of population connectivity. (5) With few exceptions, population regulation has barely been investigated. (6) We have increasingly integrated landscape configuration of habitats, large-scale habitat disturbances, and habitat quality impacts into models of seasonal and overall demographic success. (7) The post-breeding season (late summer for latitudinal migrants) is increasingly appreciated for its impacts on demography. (8) We recognize the diverse ways that avian brood parasites, nest predators, and food availability affect demography. (9) Source-sink and meta-population models help us understand migratory avian distributions among fragmented habitats. (10) Advances in modeling have improved estimates of annual survival and fecundity, but for few species. (11) Populations can be limited by ecological conditions in winter, but habitat needs are poorly known for most species at this time. (12) Migration tends to occupy broad spatial fronts that may change seasonally or when migrants cross major barriers. En route conditions can limit migrant populations; linking migration habitat quality indicators to fitness or population consequences presents a major challenge. (14) A variety of intra-tropical Neotropical migration patterns are recognizable, but almost nothing is known about these systems beyond descriptions of a few typical species' movements. (15) Global climate change scenarios predict range and phenology shifts of Neotropical migrant bird populations that must be considered in conservation plans. Future studies will depend on new technologies and the integration of modeling with sophisticated, large-spatial-scale measurement and parameter estimation; whether the pace of research and management involving migratory birds can match the growth of environmental threats remains to be seen.

“…Intermediate levels of forest cover (and greatest levels of fragmentation), characteristic of low density residential development and rural fringes, provide sufficient habitat for native forest species along with edge habitats and resource supplements favorable to early successional and synanthropic species Marzluff 2004, 2006;Blewett and Marzluff 2005;Marzluff 2005;Withey and Marzluff 2009). Overall declines in biodiversity occur at high levels of urbanization and forest loss Marzluff 2004, 2006;Hepinstall et al 2008Hepinstall et al , 2009Whittaker and Marzluff 2009). It is important to note in this system, as in many ecological systems, diversity is increased by fragmentation of uniform land covers so that many distinct types of habitats are found in close proximity.…”

“…To date, most studies have focused on nest success along an urban gradient using artificial nest studies (e.g., Gering and Blair 1999;Jokimäki and Huhta 2000;Thorington and Bowman 2003;Blair 2004), or less commonly, real nests (Blair 2004), although some have measured bird productivity in undeveloped fragments within urban environments (e.g., Leston and Rodewald 2006;Marzluff et al 2007;Reidy et al 2008). Only two studies have quantified nesting (Ryder et al 2010) or post-fledging survival (Whittaker and Marzluff 2009) for birds within the urban/suburban matrix.…”

Population demography of Gray Catbirds in the suburban matrix: sources, sinks and domestic cats

Understanding factors that limit the productivity and survival of birds in rapidly changing human-dominated landscapes are key to managing future population persistence. To date, few studies have quantified both nest success and post-fledging survival for birds breeding within the suburban matrix. Here, we estimated nest success and juvenile post-fledging survival for Gray Catbirds (Dumatella carolinensis) and used those site-specific parameters to model source-sink dynamics at three sites in suburban Washington DC (USA). Cumulative nest success probability varied substantially among suburban sites and indicated that in some cases suburban habitats may provide suitable breeding sites for passerine birds. In addition, we documented the effects of sex and brood size on postfledging survival rates and determined the role of predation on dispersing fledglings. Like nest success, estimates of post-fledging juvenile survival also varied among sites and highlight the importance of site-specific demographic estimates in urban habitats. Predation accounted for 79% of all mortalities, with 47% of known predation events attributable to domestic cats (Felis catus). Our models of source-sink dynamics underscore the importance of seasonal recruitment parameters for calculating population growth rate and subsequent persistence. This study provides parameter estimates for two critical life history stages in the avian annual cycle in the suburban matrix and posits that predation drives differential nest and postfledging survival within human-dominated environments.Keywords Cats Á Nest survival Á Post-fledging survival Á Urbanization Á Source-sink dynamics
