In this essay, I review and discuss the subject of capture, care, and legal sale of live birds within the framework of green criminology and present some elements and problems this trade faces based on research consisting of 75 interviews with aviaries and public officials as well as an ethnographic immersion in 22 locations in eight states in Mexico. The traditional use of birds, allowed through a system of subsistence permits, guarantees the human rights of the people who participate in this activity. However, as with other issues related to the use of wildlife, the use of birds continues to be a controversial issue. It is essential to promote a fair debate to ensure a constructive understanding between all the actors involved.

In the context of this phenomenon, there are pilgrimages with tourism potential that represent an opportunity for economic development. Therefore, the objective of this manuscript was to analyze the pilgrimages of people who inherited a pre-Hispanic profession in Mexico as a potential resource for cultural and religious tourism. The pilgrimages of the families that traditionally dedicate to bird trade, which consists to catch birds in an artisanal way and sell trained song birds. We identified pilgrimages with song birds in San Luis Potosi, State of Mexico, Jalisco, Queretaro, Hidalgo and Mexico City where pajareros carry cages stacked vertically in the back with song birds such as mockingbirds and solitaires to the church to celebrate a mass. Song birds are an offering to give thanks to the Virgin ...

El dzibabán es un mímido tropical endémico de la península de Yucatán muy poco estudiado. El estudio lo realizamos en la costa norte de la Reserva de la Biosfera de Sian Ka’an, México, entre febrero y agosto de 2008. Presentamos medidas de culmen, tarso y masa corporal. Proponemos un método de sexado válido durante la temporada no reproductiva, ya que los machos presentaron longitud de cuerda alar mayor que las hembras. La coloración del ojo puede ser un criterio suplementario para determinar la edad, puesto que los individuos de segundo año presentaron frecuentemente coloración ocular marrón, similar a los individuos de primer año. La temporada reproductiva inicia en abril y termina a mediados de agosto. El ciclo del nido es de 27 y 32 días y el tamaño de nidada es de dos a tres huevos. El macho construye la mayor part...

El objetivo de este trabajo es identificar los impactos de esta actividad en los Parques Nacionales Sierra de San Pedro Mártir y Constitución de 1857. Para ello, se realizó observación directa y 18 entrevistas semiestructuradas a funcionarios y habitantes de las áreas de estudio. Entre los resultados más sobresalientes se identificaron los impactos al medio natural y la interacción entre funcionarios, habitantes locales y turistas, así como las diferencias y similitudes de los impactos entre ambos parques. Para las dos áreas de estudio se sugiere prestar atención en los impactos ecológicos, dado que los programas de desarrollo estatal promueven aumentar el número de visitantes en los parques sin considerar los daños que esto puede representar en sus ecosistemas. Hay escasos estudios a nivel nacional que abarquen aspectos sociales y económicos del turismo en áreas naturales, por ello se recomie...

It has survived through bird traders, called pajareros, which is a local name given to the trade (derived from pájaro, the Spanish word for bird). However, the trade of birds has not been sufficiently described; therefore, the goal of this paper is to analyze the bird trade in Mexico using the components of an ethnoecology scheme known as kosmos-corpus-praxis complex. Qualitative research techniques were used, including ethnographic immersion, participative research, and interviews of 79 pajareros in 22 localities in nine Mexican states. The activity of the pajareros occurs within their households, with each member having distinct roles. The roles involved in bird trading are capturing, acclimation, maintenance, and sale. Their assignment depends on gender, age, and residential location (rural or urban). Beyond their households, the pajareros are well organized in trade unions and are represe...

The results indicate that the state of conservation in general of the PNA is good. However, of all activities tourism represents the sector providing the greatest pressure on the archipelago complex, because it is a growing activity. Although tourism being carried is ecotourism and adventure tourism, this activity still nevertheless produces pollution, disturbance of flora and fauna, introduction of exotic species, and problems with the fishing sector by the use of common areas.

Hay una pequeña colonia de lobos marinos Zalophus californianus (Lesson, 1828) en una zona denominada “Roca Tortuga (RT)” incluida en un área natural protegida, a 2 km de la costa, que se considera una atracción turística. Los barcos recreativos realizan los encuentros de los visitantes, y entran en contacto con los lobos marinos. Sin embargo, no existe un control directo sobre las visitas turísticas a la colonia en temporada alta. El objetivo de esta investigación fue evaluar la experiencia de los turistas a esta colonia de lobos marinos. Se emplearon encuestas para analizar su percepción hacia la conservación de los lobos marinos y se elaboraron observaciones directas (interacciones turista-lobo marino) para validar los resultados. Menos del 15% de las personas recibió algún tipo de información sobre la biología o conservació...

En el presente artículo se evalúa si el turismo rural es una alternativa de desarrollo territorial en Llachón, donde se desarrolló de manera autogestiva. En el estudio se utilizó una metodología mixta que permitió obtener información de carácter cuantitativo y cualitativo, para lo cual se aplicaron encuestas y entrevistas semiestructuradas a una muestra de las familias que trabajan con turismo y con quienes no lo hacen, para poder hacer una comparación de los dos grupos. De los resultados obtenidos, se concluye que la actividad del turismo rural en la comunidad de Llachón, contribuye al desarrollo territorial, ya que las familias de los entrevistados que se dedican al turismo rural mejoraron ...

Th e California sea lion, according to recent studies, inhabits the coasts of northwestern Mexico during the months from November to May (6 months). In this period, around 35,531 tourists visited this aquatic animal in its natural habitat, just 2 km from the coast. Th is economic activity generated an annual income for tourism services of $11,425,120.00 M.N ($626,517.24 USD) that off er ecotourism of the sea lion as a profi table attraction in the bay known as the Pearl of the Mexican Pacifi c. In the Bay of Mazatlan, this marine mammal enjoys a privileged place on the boardwalk, where there is a monument highlighting its importance in the port. Th is animal is the only pinniped species resident in the Gulf of California, with an approximate registry of 40 colonies. Also, there is a temporary´houseíntemporary´houseín a rock formation called Roca Tortuga (RT) at the geographic coordinates of 23 ° 11'13.15 "N and 106 ° 26'45.68" in the winter and spring months. Recent studies conducted 245 surveys of sea lions at Roca Tortuga during the winter of 2006 and the spring of 2013 by a local ecotourism company. Sea lions were observed at the study site from September to May-June, but with interannual variations in their abundance. In the winter seasons of 2011-2012 and 2012-2013 anomalies were recorded in their abundance, with minimal visitation during 2012. Th e most important environmental factors were determined: the water temperature shows seasonal variations, with maximum values from July to September (30ºC) and minimums in December (19ºC). Th e feeding of this mammal is based on sardines Sardinops sagax caeruleus (Girard, 1854), Pacifi c mackerel Scomber japonicus Houttuyn, 1782 and hake Merluccius sp Rafi nesque, 1810.

El dzibabán es un mímido tropical endémico de la península de Yucatán muy poco estudiado. El estudio lo realizamos en la costa norte de la Reserva de la Biosfera de Sian Ka'an, México, entre febrero y agosto de 2008. Presentamos medidas de culmen, tarso y masa corporal. Proponemos un método de sexado válido durante la temporada no re-productiva, ya que los machos presentaron longitud de cuerda alar mayor que las hembras. La coloración del ojo puede ser un criterio suplementario para determinar la edad, puesto que los individuos de segundo año presentaron frecuentemente coloración ocular marrón, similar a los individuos de primer año. La temporada reproductiva inicia en abril y termina a mediados de agosto. El ciclo del nido es de 27 y 32 días y el tamaño de nidada es de dos a tres huevos. El macho construye la mayor parte del nido y la hembra incuba los huevos. La mayoría de los nidos se construyó en la palma Thrinax radiata y el arbusto Pithecellobium ke yense. En conclusión, el dzibabán comparte características similares con Dumetella carolinensis y las principales diferencias son debidas a su distribución tropical. Palabras clave: Mimidae, península de Yucatán, dimorfismo sexual, historia natural. Abstract In the present study, we report morphometric and reproductive characteristics of the Black Catbird, Melanoptila glabrirostris, some of them shown here for the first time. The Black Catbird is a tropical mimid endemic to the Yucatán Peninsula that is not well studied. Fieldwork was conducted in the North coast of the Sian Ka'an Biosphere Reserve, México, from February to August 2008. We present measurements of bill, tarsus, and body mass. We propose a method for sexing outside the breeding season because males had longer wing chords than females. We demonstrate that eye color can be an extra criterion for age determination because second-year birds more frequently had brown eyes, similar to the eye color of hatch-year birds. Breeding season lasted from April until at least the middle of August. The nest cycle was 27 to 32 days long, and clutch size was from two to three eggs. Mostly males built nests and females incubated the eggs. Most of the nests were built on Thrinax radiata palm and Pithecellobium keyense bush. In conclusion, the Black Catbird shares characteristics with Gray Catbird, and the main differences are due to its tropical distribution.

A group of people called pajareros are required by law to apply for permits for harvesting and selling birds, which are authorized by Mexican environmental and wildlife government officers mostly for subsistence use. While environmental manager officers interact with stakeholders as part of their work, how they actually interrelate with pajareros and make final decisions remains unclear. Therefore, we describe regulation of bird use in Mexico, analyze criteria applied, and provide the opinions of the four key officers involved in natural resource management obtained in open interviews held during 2012. Officers have a stereotyped view about pajareros and a close, sometimes conflicting relation with them, express good knowledge of socialenvironmental conflict related with songbirds, and decide songbird harvest rates based on the three pillars of sustainability, but prioritizing environmental laws over social needs.

“hecho social” como una “cosa”, reduciéndolo a algo que permitiera a
ciertos científicos, estudiosos de la sociedad y las personas, llamar “física social” a la ciencia que ejercían. Si estrellas, piedras, plantas y animales podían ser medidos en nombre de una precisión siempre imprecisa, pero al menos convincente por algún tiempo, y si ratones y monos eran encerrados en jaulas, con sus pequeños cuerpos conectados a cables en cuyo extremo opuesto encontrábamos exactos “instrumentos científicos de investigación”, ¿por qué no hacerlo también con las personas?
