Avian Conservation and Ecology

Research Paper INTRODUCTION The Black Rail (Laterallus jamaicensis) is a secretive marsh bird and the smallest member of Family Rallidae in North America (Eddleman et al. 2020). It inhabits high marsh habitat with moist soil and scattered pools but does not tolerate standing water of depths of more than ~5 cm (Hand et al. 2019).

Research Paper ABSTRACT The establishment of the Quebrada del Condorito National Park (QCNP) in 1996 (Córdoba, Argentina) led to a significant reduction in livestock numbers. Conversely, at the adjacent Pampa de Achala Provincial Water Reserve (PAPWR), livestock loads have been maintained to date.

Research Paper ABSTRACT Understanding population dynamics and developing effective conservation strategies for migratory birds requires information on geographic and temporal linkages of populations across the full annual cycle.

Research Paper INTRODUCTION King Rails (Rallus elegans) are secretive marshbirds that have split migration strategies, with year-round resident (hereafter “resident”) populations in coastal wetlands along the southeastern United States, and migratory individuals distributed during the breeding season across the northern part of their range (primarily the U.S. Great Lakes states and eastern Great Plains; the U.S. Atlantic coast, north through to Connecticut; and as far as southern Ontario,...

Research Paper ABSTRACT Central to understanding species population dynamics is accurate estimation of vital rates, including mortality and fecundity. Human activities can create novel habitats that attract individuals but ultimately provide suboptimal conditions, potentially reducing survival and creating ecological traps. The Bank Swallow (Riparia riparia), a species in decline in Canada, typically nests in cavities along eroding lakeshores and riverbanks.

Research Paper ABSTRACT Migratory songbird populations are declining across North America, and collisions with glass-fronted buildings have become one of their leading causes of mortality. Finding practical ways to curb these collisions is a key conservation priority, but large-scale solutions remain elusive because retrofitting glass façades and enforcing lights-out policies are often prohibitively costly and logistically difficult.

Research Paper ABSTRACT The Connecticut Warbler (Oporornis agilis) is undergoing significant population declines, particularly near the southern limit of its breeding range. To effectively respond to these declines, it is critical to refine population trend estimates and gather comprehensive information about this understudied species throughout its annual cycle.

Research Paper, part of a special feature on A Synthesis of Data, Tools, and Resources for Avian Research and Conservation Planning in Canada INTRODUCTION Long-term population monitoring is a key element of species conservation: it allows us to understand the spatial distribution of species, track changes in populations over time, identify potential drivers of change, and evaluate the effects of conservation or management actions (Lindenmayer et al. 2022).

Research Paper, part of a special feature on Partners in Flight International Science Committee: Migratory Bird Conservation Tools and Applications INTRODUCTION Over 50% of forest-dependent birds in the West are in decline, one of the broadest set of avian declines of any habitat (Rosenberg et al. 2019).

Research Paper ABSTRACT Piping Plover (Charadrius melodus) was among the first species recognized as being at risk in Canada in 1978. Extensive efforts to recover the coastal population breeding in eastern Canada (C. m. melodus) at the northeastern edge of the species’ range have been accompanied by intensive demographic monitoring.
