We report on the intra-Amazonian migration of a pair of Orinoco Geese (Neochen jubata) from Manú National Park, Peru. The species is Critically Endangered in Peru, so a major aim of the study was to aid conservation planning by learning the wet season location of the country's last known breeding population. We captured a breeding pair on October 27, 2010, and fitted the birds with Microwave Telemetry, Inc. GPS/Argos satellite PTT's. The pair migrated ∼655 km from Manú National Park to the Llanos de Moxos, Bolivia (Dept. of Bení) in a predominantly longitudinal migration, reaching their final destination on December 23, 2010. Major movements (>5 km per time period) were almost exclusively at night and were undertaken with and without moonlight. Foraging areas used at stopovers in the Llanos de Moxos were remarkably limited, suggesting the importance of grazing lawns maintained by the geese and other herbivores, possibly including cattle. Orinoco Geese are resident in the Llanos de Moxos year-round, so the Manú geese represent a partial migration from the Bení region. We hypothesize that cavity nest limitation explains the partial migration of Orinoco Geese from the Llanos de Moxos.

El objetivo del estudio fue determinar los valores hematológicos y bioquímica sérica del caimán blanco (Caiman crocodilus) de vida libre en Madre de Dios, Perú. Se capturaron 30 individuos (26 machos y 4 hembras) en las márgenes del río Madre de Dios. Las muestras sanguíneas se obtuvieron por punción en la rama dorsal de la vena craneal. Los valores hallados fueron: eritrocitos 1.45±0.97 x 106/μl, hematocrito 22.63±4.16%, hemoglobina 7.86±2.10 g/dl, VCM 190.6±76.9 fl, HCM 63.49±20.96 pg, CMCH 34.96±7.80 g/dl, leucocitos 13.18±5.85 x 103/μl, eosinófilos 1.54±1.21 x 103/μl, basófilos 1.31±1.20 x 103/μl, linfocitos 5.77±4.03 x 103/μl, monocitos 0.17±0.38 x 103/μl, heterófilos 2.16±2.59 x 103/μl, ALT 48.59±14.34 U/L, AST 114.0±28.5 UI/L, GGT 1.8±1.6 UI/L, creatinina 0.51±0.35 UI/L, colesterol 101.8±42.3 UI/L, glucosa 98.1±30.7 mg/dL, proteínas totales 5.01±1.00 g/dl, albúmina 1.65±0.29 g/dL, globulinas 3.13±1.08 g/dL, calcio 10.11±1.63 mg/dL y fósforo 6.44±1.09 mg/dl. Se encontraron diferencias significativas según el sexo para los valores de VCM y CMCH.

El objetivo del estudio fue determinar los valores hematológicos de la taricaya (Podocnemis unifilis) en dos estaciones del año en un parque zoológico de Iquitos, Perú. El zoológico presenta una población de 80 taricayas. En el estudio se trabajó con 30 tortugas (18 machos, 12 hembras). Las muestras de sangre fueron tomadas en invierno (febrero) y verano (julio) y se analizaron utilizando la cámara de Neubauer y el dilutor Natt & Herrick. La estación del año influyó los valores hemáticos, aumentando el número de eritrocitos y azurófilos en verano, y de linfocitos y trombocitos en invierno.

The rock dove Columba livia is an exotic and feral bird that has been described as carrying various agents potentially pathogenic to man and other birds, including bacteria such as Salmonella spp. and E. coli, however, there are few studies regarding infectious disease agents carried by the species in our country. The objective of the study was to determine the enterobacterias present in this free-living bird resident in the City of Lima. During the months of June and July of 2014, 27 adult individuals of C. livia were captured in two zoos located in the districts of Chorrillos and San Juan de Miraflores. A cloacal swab was made to each bird and transported in the Cary Blair transport medium at 4 °C to a private laboratory. In the laboratory, samples were plated on McConkey agar and SS agar, and then proceeded to the identification using biochemical tests (TSI, LIA, Indol, SIM, Citrate, Methyl Red and Voges Proskauer). A total of 35 bacterial colonies were isolated 85.19 % (23/27) from the samples: 62.96 % (17/27) Escherichia coli, 11.11 % (3/27) Enterobacter aerogenes, 11.11 % (3/27) Klebsiella sp., 11.11 % (3/27) Proteus vulgaris, 7.41 % (2/27) Salmonella pullorum, 14.29 % (14/27) Shiguella sp., 11.11 % (3 / 27) Staphylococcus aureus and 3.70 % (1/27) Staphylococcus sp. Here, we report a high frequency of enterobacteria of interest in public health, evidencing the importance of considering rock dove as a reservoir for zoonotic bacteria.
