Corvids are opportunistic omnivores and facultative scavengers, but there no direct records of Cyanocorax species scavenging on carrion. We documented feeding behavior the White-throated Magpie-Jay (Cyanocorax formosus) a road-killed Common Pauraque (Nyctidromus albicollis) in northwestern Costa Rica. On 25 August 2023, we observed three Magpie-Jays carcass Pauraque, likely killed by collision with vehicle, along gravel road near Taboga Forestry Reserve. This provides de first evidence...
El pizote, Nasua narica, se distribuye desde Arizona, EE. UU., hasta Colombia, el nivel del mar 2,879 m. Presenta comportamientos terrestres y arbóreos, con actividades reproductivas en árboles. Durante la reproducción, bandas machos adultos solitarios construyen nidos Las hembras preñadas separan grupo para dar a luz criar sus crías arbóreos aislados. Entre 2016 2018, realizamos censos de mamíferos Parque Nacional Palo Verde, noroeste Costa Rica, una visita cada semestre durante 3 días....
The jaguar Panthera onca is threatened throughout its range and categorized as Near Threatened on the IUCN Red List. To inform conservation of population in Corcovado National Park, Costa Rica, size was estimated using data from a 3-month camera trap study. Individuals were identified their coat patterns. resulting density estimate 6.98 ± SD 2.36 individuals per 100 km 2 lower than expected. sex ratio 1.33 males female, minimum home ranges two 25.64 6.57 . Hunting pressure white-lipped...
Growth of yeast species during the fermentation a grape juice inoculated with <i>Kluyveromyces thermotolerans</i> and two others strains <i>Saccharomyces cerevisiae</i> were studied. Although dominance <i>K. over four to five days was observed in must this yeast, <i>S. became predominant before completed. The growth pattern for considered somewhat different. In strain I (<i>S. chevalien</i>), prevailed throughout fermentation, while II (Fermichamp), overtaken by <i>Candida stellata</i> early...

Aunque no se han cuantificado de manera sistemática en varias especies y poblaciones, los trastornos cromáticos las aves son presumiblemente raros y, a menudo, difíciles o incluso imposibles identificar correctamente. La anormalidad pigmentaria con mayor prevalencia entre es el Encanecimiento Progresivo, aunque la mayoría formas heredables directa. Además, Progresivo confunde menudo Leucismo Albinismo. tangara azuleja, conocida como viudita Costa Rica, Thraupis episcopus, distribuye desde...
El leucismo, una mutación que se clasifica dentro de la categoría más amplia manchas blancas, provoca plumas o plumajes blancosen lasaves. Aunque es frecuente entre aves domésticas y cautivas, su ocurrencia en naturaleza relativamente rara. Esta interrumpe el desarrollo normal las células producen melanina. Las leucísticas pueden presentar plumaje completamente blanco parches blancos parciales extensión del permanece consistente a lo largo vida. En casos parciales, leucismo manifiesta manera...
Although there are 935 species of birds in Costa Rica, scientific reports pigmentation abnormalities this group limited. Nevertheless, several cases have been recently documented, including Leucism, Ino mutation, Progressive Graying, Dilution, and two unusual color aberrations a toucan motmot. Here we describe seven observed over period five years native Rica. An Eastern Wood-Pewee Contopus virens White-collared Manakin manacus candei were Brown. A Scintillant Hummingbird Selasphorus...
Abstract A taxonomic framework for South American cottontail rabbits (Lagomorpha: Leporidae: Sylvilagus) was recently published by Diersing and Wilson (2017). Although we agree with some of its conclusions (e.g., species status S. apollinaris fulvescens), disagree others. We provide herein evidence supporting andinus as a valid based on morphological characters novel molecular data. also details the fulvescens that support separating these from brasiliensis. adduce data suggestive to effect...
The effects of grape juice clarification on the initial population and growth wild yeasts were studied. Two musts clarified using different treatments. One them was treated with pectolytic enzyme, then a single cold treatment at 3°C to 5°C performed. other must submitted an additional settling combined bentonite, gelatine, coloidal silica. Despite occurrences yeast species in musts, treatments similar. almost all decreased during clarification, yet end levels reached similar those existing...
Although Costa Rica occupies a mere 0.03% of the Earths land area, it nevertheless has recorded within its borders approximately 5% global diversity mammals, thus making one worlds megadiverse countries. Over past ten years, 22 species have been added to countrys inventory, bringing total number known as here documented 271; Chiroptera account for these, having grown 124 from 114; rodents increased by eight species, 47 55, with caveat that we include three invasive Muridae gone feral. In...
La diversidad de murciélagos Honduras, aunque es muy rica y variada, recibió relativamente poca atención hasta recientemente. Nuevas actividades desarrollo económico nuevas necesidades conocimiento, junto con una nueva generación biólogos campo, están impulsando la investigación los del país. Debido a esto, se elaboraró clave campo para identificación Honduras. El documento contiene: separación e las ocho familias subfamilias Phyllostomidae, siete claves individuales separar especies dentro...
El cormorán neotropical (Phalacrocorax brasilianus) es un ave acuática de color negro brilloso y amplia distribución geográfica. A pesar que las aberraciones no son comunes en los animales silvestres, existen variaciones cromáticas se deben mayoritariamente a alteraciones genéticas. Aquí reportamos la presencia individuo adulto del con leucismo total. lo observamos árbol mangle botón (Conocarpus erectus) el 14 agosto 2013 0920h. Este era miembro una colonia mixta anidamiento ubicada canal...
