“…O'Shea et al 2011found that 35% of colonies roosting in buildings were excluded over a period of 4 years, so this conflict may represent a serious conservation issue. Colony displacement can lead to disruption of social groups, increased individual mortality (Aguiar et al, 2012;Neilson and Fenton, 1994) and decrease of reproductive success (Agosta, 2002). Unsustainable alteration of roosts, including building modification or demolition (O'Shea et al 2011) is another major conflict factor.…”

In this article we review the current knowledge of the effects of urban expansion on bats and assess the potential of these mammals as bioindicators of urbanization. The response of bats to this process is highly species-specific: some species tolerate urban habitat or are even favoured by its roosting or foraging opportunities, others are affected by the loss or fragmentation of key natural habitat, or by the physical and chemical pollution associated with urbanization. Species responses generally translate into altered community structures, with few markedly dominating species. We propose different hypothetical models of bat fitness along an urbanization gradient and discuss why bat population density may not be an effective fitness proxy to assess the reactions of these mammals to urban expansion. We also suggest that urban habitat may act as an ecological trap even for apparently synurbic species. Overall, bat sensitivity to urbanization makes these mammals promising candidates to track the effects of this process of land use change on the biota, but more studies, specifically tailored to explore this role, are needed.

“…Existen observaciones de individuos de F. sparverius cazando murciélagos a lo largo del continente americano (James & Hayse 1963, Aguiar et al 2012, Pagnoni 2013, Lenoble et al 2014, Rodríguez-San Pedro & Allendes 2015, Martínez et al 2016) y observaciones en Ecuador (Salazar et al 2012) cazando serpientes (Colubridae), aunque éstos ítems no han sido reportados en egagrópilas; sin embargo, con el desarrollo de futuros estudios en otras localidades, será posible esclarecer los límites y preferencias alimenticias de éste falconiforme.…”

“…El Cernícalo Americano (Falco sparverius) es una rapaz de tamaño pequeño, ampliamente distribuida en el continente americano, extendida desde Alaska hasta Tierra de Fuego en Argentina, contando con 17 subespecies a lo largo de su distribución (White et al 2016). Aspectos alimenticios de F. sparverius han sido estudiados tanto en Norte y Centroamérica (Heintzelman 1964, Jenkins 1970, Cruz 1976, Hiraldo et al 1991, así como en Sudamérica, donde se han desarrollado estudios de historia natural en Venezuela (Balgooyen 1989); mientras análisis de egagrópilas, restos de presas y avistamientos de alimentación han sido efectuados en Chile (Mella 2002, Figueroa & Corales 2002, Figueroa & Corales 2004, Rodríguez-San Pedro & Allendes 2015, Argentina (Sarasola et al 2003, Liébana et al 2009, Santillan et al 2009, Pagnoni 2013) y Brasil (Cabral et al 2006, Zilio 2006, Aguiar et al 2012.…”

Dieta del Cernícalo Americano (Falco sparverius Linnaeus, 1758) en dos hábitats interandinos del norte de Ecuador

<p>El cernícalo americano es una especie de ave rapaz ampliamente distribuida desde Alaska hasta Tierra de Fuego en Argentina. Su dieta generalista está basada principalmente en invertebrados. En Ecuador existe escasa información biológica de ésta especie, desconociéndose aspectos de alimentación. En el presente trabajo se da a conocer la dieta del cernícalo americano, por medio del análisis de egagrópilas colectadas en dos hábitats ubicados en la región interandina en el norte de Ecuador. Los ítems más representativos para Sangolquí y Tababela fueron los coleópteros (48.4 y 39.5%), seguidos por orthópteros (31.3 y 30.7 %) respectivamente. En términos de biomasa, los mamíferos son los más importantes dentro de la dieta del cernícalo americano con el 40.3% para Sangolquí y el 70.8% en Tababela. El índice de Shannon (H´= 1.894) indica una mediana diversidad de presas, y la amplitud de dieta (0.26) indica que ésta especie presenta una dieta especialista, difiriendo de otros hábitats donde presenta dieta generalista.</p>

“…In México, it is found in tropical deciduous forest and trees of the genus Cupresus, around rivers and thorny deciduous riparian forests (Gardner 1963;Jones and Álvarez 1964;Baker and Jones 1972;Wang et al 2003), as well as in tropical vegetation, thorny bushes, cacti, oak, grasslands, and mesquites (Baker et al 1967;Wilson 1985;López-González and García-Mendoza 2006). In Honduras, it was reported in pine-oak forests with pastures converted for livestock (Espinal et al 2016); in Venezuela, in very humid pre-montane forest (Ochoa 1984); in Bolivia, it was reported in spiny trees along the edges of fresh water sources (Ibáñez and Ochoa 1989); in Brazil, it has been recorded in the Cerrado, Caatinga, and Atlantic Forest biomes (Taddei and Garutti 1981;Bredt 2003;Eger 2008;Bianconi et al 2009;Tavares et al 2010;Aguiar et al 2012;Garbino 2016;Oliveira et al 2019); whereas in Perú, N. aurispinosus is distributed in the Dry equatorial forest (characterized by flora of the families Capparaceae, Cassuarinaceae, Fabaceae, and Loranthaceae), Pacific coastal desert, and Subtropical puna (Ortiz de la Puente 1951;Sanborn 1951;Eger 2008;Velazco et al 2013;Pari et al 2015).…”

Nyctinomops aurispinosus is one of four species of the genus Nyctinomops (Molossidae) and is considered monotypic. This insectivorous species has a wide but poorly known neotropical distribution. This study documents the first record of the species for the Sama Valley, Tacna department, Perú. In addition, a current distribution map of the species is presented together with facts concerning its dietary composition. The specimen was collected using mist nets during a local bat study and compared with N. aurispinosus individuals in the scientific collection of the Museo de Historia Natural Javier Prado, Universidad Nacional Mayor de San Marcos. The distribution map was made of published records and the diet of the specimen was analyzed by stereoscopy of the contents of its digestive tract. The collected specimen was identified as an adult male N. aurispinosus in reproductive condition. Analysis of the digestive tract contents showed that its diet was composed of lepidopterans. The current distribution map of the species consisted of a total of 78 published records. This new record for Tacna department expands the distribution of N. aurispinosus ca. 270 km to the south of Camaná, Arequipa department, becoming the southernmost record for the Pacific coast. The lepidopteran remains in the digestive tract show that its diet is similar to those reported for other molossids. This finding extends the known distribution of this species to the southwest of South America and increases to ten the number of bat species known from Tacna department. The proximity of this Peruvian record to Chilean territory and regional habitat continuity suggests the probable presence of N. aurispinosus in that country.
