Raptors provide critical ecosystem services, yet there is currently no systematic, global synthesis of their conservation status or threats. We review the International Union for Conservation Nature's Red List to examine status, distributions, threats, and recommendations all 557 raptor species. further assess significance Important Bird Biodiversity Areas (IBAs) conservation. also determine which countries contain most species listed under Memorandum Understanding on Migratory Birds Prey in...
Resumen La naturaleza carismatica y la enigmatica disminucion poblacional de Falco sparverius ha provocado el interes preocupacion tanto cientificos (ciudadanos profesionales) como del publico en general. Aunque se han propuesto diversas razones causas esta disminucion, hay poca o nula evidencia empirica para mayoria las amenazas hipotetizadas consecuentemente no existen recomendaciones gestion apoyadas empirica. Presentamos investigaciones futuras sobre causa F. sparverius. Ademas,...
Species considered raptors are subjects of monitoring programs, textbooks, scientific societies, legislation, and multinational agreements. Yet no standard definition for the synonymous terms "raptor" or "bird prey" exists. Groups, including owls, vultures, corvids, shrikes variably based on morphological, ecological, taxonomic criteria, depending authors. We review various criteria previously used to define we present an updated that incorporates current understanding bird phylogeny. For...
Most raptor populations are declining and nearly a fifth threatened with extinction; thus there is need to increase collaboration ensure efficient effective research, management, conservation. Here, we introduce the Global Raptor Impact Network (GRIN; www.globalraptors.org), tool enhance conservation impact of research community. We provide an overview history current state GRIN, including plans for expansion. Predecessors GRIN include The African DataBank, which was launched in 2012...
There are currently four world bird lists referenced by different stakeholders including governments, academic journals, museums and citizen scientists. Consolidation of these is a conservation research priority. In reconciling lists, care must be taken to ensure agreement in taxonomic concepts—the actual groups individual organisms circumscribed given scientific epithet. Here, we compare species-level concepts for raptors across the highlighting areas disagreement. Of 665 raptor taxa...
Demographic differences between stable and declining populations can lend insight into drivers of population decline. The American Kestrel Falco sparverius is a widespread often‐studied falcon, yet its demography poorly understood, the causes observed declines across much North America remain unknown. Using integrated models sensitivity analysis, we examine how vital rates drive growth in levels Kestrels at four discrete study sites – Florida, Idaho Pennsylvania with nestbox occupancy, New...
Identifying small, isolated populations is a conservation priority, not only because isolation may result in negative fitness consequences, but these also harbor unique genetic diversity. The Greater Sage-Grouse (Centrocercus urophasianus) widespread obligate species of the sagebrush biome western North America that has experienced range-wide contraction over past century. To prevent local extirpation, efforts have been made to identify populations. Here, we analyzed 16 microsatellite loci...
Abstract Identifying population genetic structure is useful for inferring evolutionary process and comparing the resulting with subspecies boundaries can aid in species management. The American Kestrel (Falco sparverius) a widespread highly diverse 17 total subspecies, only 2 of which are found north U.S./Mexico border (F. s. paulus restricted to southeastern United States, while F. sparverius breeds across remainder U.S. Canadian distribution). In many parts their range, Kestrels have been...
Hundreds of zoo-based or wildlife webcams have become available during the past twenty years, mostly with goal educating public. However, there has been virtually no peer-reviewed research that evaluates education, conservation, scientific impact webcams. Here, we provide one few examples a webcam used for citizen science, and only test efficacy crowd-sourced data collection using The Peregrine Fund streamed six seasons American Kestrel (Falco sparverius) nests same nest box from 2012...
Scoping reviews, in which the literature on a given topic is systematically collated and summarized, aid searches highlight knowledge gaps topic, thus hastening scientific progress informing conservation efforts. Because much research targeted at species level, ornithology bird would benefit from scoping reviews of individual species. We present apply framework for three disparate raptor species: California Condor Gymnogyps californianus , Harpy Eagle Harpia harpyja Gyrfalcon Falco...
Falco sparverius es un pequeño halcón cuya población está disminuyendo en América del Norte, pero aún no se han identificado los factores que causan esta disminución. Los conservacionistas abogado por una mayor comprensión de la conectividad migratoria especie para identificar las posibles causas disminución pueden ocurrir durante varias partes su ciclo anual. Para muchas especies aves, forma más común y directa determinar colocando sobre ellas dispositivo seguimiento documente sus...
Forest canopies contribute significantly to global forest biodiversity and ecosystem functioning, yet are declining understudied. One reason for a knowledge gap is that accessing can be difficult dangerous. Thus, lack of relevant canopy access skills may compromise gain personal safety. We assessed skill levels in methods self-perception amongst ecologists worldwide via web-based survey, available four languages. obtained responses from expert arborists as control group. From 191 respondents...
Citizen science programs can be powerful drivers of knowledge and scientific understanding and, in recent decades, they have become increasingly popular. Conducting successful research with the aid citizen scientists often rests on efficacy a program’s outreach strategies. Program evaluation is recognized as critical practice for practitioners to ensure that all efforts, including outreach, contribute overall goals program. The Peregrine Fund’s American Kestrel Partnership (AKP) one such...
American Kestrels (Falco sparverius) are declining across much of North America, yet the initial timing population decrease is unclear. In an attempt to elucidate when kestrel declines began, we examined historical descriptions abundance within northeastern United States. Within The Peregrine Fund's research library, found 54 in states dating from 1839 2013. Our analysis indicates a cubic trend with peak occurring 1951. After that peak, began its current decline, appears have been stable...
Abstract Climate-driven advances in spring can result phenological mismatch between brood rearing and prey availability consequently cause decreased productivity birds. How consequences of vary across species’ ranges, how individual behavior mitigate effects is less studied. We quantified the relationship mismatch, productivity, behavioral adaptations American kestrels ( Falco sparverius ) their breeding range United States southern Canada. obtained phenology data using nest observations...
Despite the American Kestrel (Falco sparverius) being one of most commonly occurring and thoroughly studied raptors in North America, it has only been documented consuming wild carrion time literature. Here, we document at least feeding on carcass a domesticated turkey (Meleagris gallopavo) near Boise, Idaho. Each day for 5 consecutive days January/ February 2018, observed unbanded female kestrel approximately 15 min per visit. Kestrels have diverse diet, but feed primarily small rodents,...
Optimal reproductive performance occurs when birds time reproduction to coincide with peak food availability. Deviation from optimal timing, or mismatch, can affect productivity, though may mediate some mismatch effects by altering their incubation behavior. We studied the consequences of nesting timing (i.e., clutch initiation relative an index spring start) on productivity across breeding range American kestrels (Falco sparverius) in United States and southern Canada, associations between...
Habitat loss is well recognized as an immediate threat to biodiversity. Depending on the dispersal capabilities of species, increased habitat fragmentation often results in reduced functional connectivity and gene flow followed by population decline a higher likelihood eventual extinction. Knowledge degree between populations therefore crucial for better management small changing landscape. A greater sage-grouse (Centrocercus urophasianus) exists northwest Wyoming within Jackson Hole valley,...
