“…En la actualidad, gracias al desarrollo de la tecnología, han aumentado en número las investigaciones en rapaces en torno a la telemetría satelital y la selección de hábitat (Sandgren et al, 2014;Domenech et al, 2015;Tikkanen et al, 2018;Hixson et al, 2022), y con ello se han hecho recomendaciones para el manejo del águila real y el hábitat asociado (Singh et al, 2016), que apoyan su conservación. Sin embargo, a pesar de las acciones como el monitoreo constante de las poblaciones reproductoras a largo plazo, conteos aéreos de nidos, paros controlados de la generación de electricidad con turbinas eólicas o ubicaciones apropiadas de los campos, prohibición de uso de pesticidas y leyes que protegen específicamente a esta rapaz, la mortalidad de esta especie es alta y requiere de más trabajo, como tener encuestas de sitios de anidación a largo plazo en toda el área de distribución del águila, así como el conocimiento de las tendencias poblacionales de forma local, el registro satelital de la distribución de individuos residentes y la asignación de fondos de todos los niveles para investigación e implementación de estas acciones (Kochert & Steenhof, 2002;Katzner et al, 2012).…”

El conocimiento sobre la selección de sitios de anidación en aves rapaces es uno de los factores críticos para realizar cualquier manejo de una población para su conservación. El águila real generalmente elige paredes de roca para anidar, y esta selección está influenciada por las características naturales y antrópicas del paisaje. En México el estudio del águila real es importante debido a que tiene un valor cultural por ser un símbolo patrio y biológico por regular las poblaciones de sus presas, además, se encuentra listada en la Norma Oficial Mexicana 059-SEMARNAT-2010 en la categoría de amenazada y existe escasa información científica publicada sobre su ecología y biología en nuestro país. Por ello, se elaboró un estudio que determinó las variables de hábitat que influyen en los patrones de selección de sitios de anidación del águila real en Janos, Chihuahua. Se buscaron sitios de anidación de águila real y sitios semejantes sin presencia de la especie para tomar los datos de dichas variables; con esta información se analizaron los datos a través de modelos lineales generalizados, tomando como variable de respuesta la presencia y ausencia de nidos y las características del hábitat de los sitios como variables predictoras. Se localizaron 15 sitios de anidación y 16 sitios sin nidos; de 15 variables medidas solo existió diferencia estadística significativa en la altura de las paredes de roca (W = 44.5, p = 0.003001). El modelo con mejor ajuste tuvo un valor de AICc de 20.6, explicando el 68% de la variabilidad de los datos e incluye las variables de altura de las paredes de roca y la rugosidad del terreno, siendo esta última estadísticamente significativa (p =0.0279). La rugosidad del terreno y la altura de la pared de la roca que se presentaron en el mejor modelo reflejando la importancia de la topografía para la selección de sitios de anidación que puede proporcionar aislamiento de perturbaciones para las águilas.

“…This could have prompted a sense of responsibility and duty for the courts to prosecute the cases involving this species. Additionally, the Bald eagle is not only protected under the Migratory Bird Treaty Act, but also under the Bald and Golden Eagle Protection Act (BGEPA) designed for the added protection of the species (Katzner et al, 2012). One approach to the aiding of the growth of the environmental conscience could potentially be the emphasis of the values and the shifting of our attitudes toward animals, because "understanding and managing wildlife is also about understanding and managing societies" (Herrmann et al, 2013, pg.…”

Wildlife crime threatens national and global security. Much of the impact of wildlife crime is felt overseas, often in developing countries, where it threatens to catalyze conflicts, hinders economic development, undermines the rule of law, and threatens peace, amongst having other negative socio-economic and security impacts. But the impact of wildlife crime also is felt in United States, both directly by undercutting state and local conservation efforts, and indirectly, by injecting illegal wildlife and wildlife products into United States markets. While some work has delved into the sentencing dynamics of broader environmental crime in the United States, little research has explored the sentencing of wildlife crime, which is recognized as being distinct in nature by both governmental bodies and academics alike. The current study explores the federal prosecutions of wildlife crimes, focusing on profiling the wildlife crime cases charged by the US Department of Justice (DOJ). By profiling cases, we aim to explore (1) the application of charges associated with wildlife crime cases via their judgment documents; (2) the wildlife species involved in prosecuted cases; (3) the distribution of cases across US federal districts; and (4) and the sentencing patterns of wildlife crimes. Further statistical analyses explore the relationships between a variety of the variables extracted. Policy recommendations are set forth accordingly.

“…In addition to habitat loss and degradation, a broad suite of direct threats to GOAE exist in North America (Katzner, Smith et al 2012;, and many of these threats are highly relevant in Sonora and elsewhere in northern Mexico. Carcasses laced with poisons targeting https://doi.org/10.…”

“…Such poisons are known to kill GOEA in the western USA , constitute major threats to GOEA in Sonora, and must be controlled and regulated before the benefits of habitat conservation and restoration can be fully realized. Similarly, incidental captures in leghold traps and snares set for mammals can be a significant source of mortality, as can lead poisoning from ingestion of ammunition in carrion in regions where hunting is common (Katzner, Smith et al, 2012;Kramer & Redig, 1997). Electrocution from power poles is a major cause of raptor mortality in the western USA, especially for large species such as GOEA, which are more likely to make contact with energized wires and components (Harness & Wilson, 2001;.…”

Distribution and habitat of the Golden Eagle (Aquila chrysaetos) in Sonora, Mexico, 1892-2019

The Golden Eagle (Aquila chrysaetos) is listed as threatened in Mexico but there is little information on populations in the state of Sonora. We amalgamated 121 records of the Golden Eagle in Sonora between 1892 and 2019, including 49 observations by the authors between 1997 and 2016. Observations were from all months of the year, peaked during the breeding season and again in December with 53.7% representing likely breeding individuals. Most observations were from the Sky Islands region and Sonoran Desert of northern Sonora, with fewer from coastal west-central and especially southern Sonora. Most observations were from grasslands (34.3%), Madrean evergreen woodland (31.3%), and desert-scrub (30.3%), and very few were from subtropical forest and thorn-scrub (≤ 2.0%) suggesting preference for open vegetation communities that foster hunting. We found evidence of recent occupation of all general portions of Sonora that were occupied historically, except in central Sonora due possibly to changes in land use and land cover. Although our results suggest broad-scale distribution has been largely stable, more focused monitoring is needed to understand population trends. Large-scale urban and agricultural development, loss of grasslands and other open environments, electrocution, and poisoning pose major threats to Golden Eagles in Sonora.
