Haematological values for captive harpy eagle (Harpia harpyja)

Decreasing of harpy eagle (Harpia harpyja) populations in natural environments, mainly in non-preserved areas, makes captive population management an important contribution to genetic diversity conservation. The aim of this study is to evaluate hematological parameters for captive harpy eagles maintained at the wild animals breeding center of Itaipu Binacional, Paraná State, Brazil. Fourteen blood samples from nine harpy eagles were collected from animals of both sexes, of different ages and with no clinical signs of disease. Significant variations were found in haematological values of hematocrit, hemoglobin, mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), leukocyte, a relative number of heterophils, absolute and relative number of lymphocytes, monocytes, eosinophils, basophils and plasma protein between groups of young (less than six months old) and adult birds. Comparing males and females there was variation in the values of erythrocytes, hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) on heterophils, absolute and relative number of lymphocytes, eosinophils and basophils. There was also variation in the values of red blood cells, hematocrit, hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), leukocyte count, absolute number of lymphocytes, eosinophils and basophils among birds that study compared to another reference birds. Due to the limited information available on harpy eagle hematology, this study will be useful to the clinical assessment of birds maintained in captivity.

Sloths in the diet of a Harpy Eagle nestling in eastern Amazon

-Prey remains of a nestling Harpy Eagle (Harpia harpyja) over 15 months in eastern Amazon, Brazil included 11 two-toed sloths (Choloepus didactylus), 9 three-toed sloths (Bradypus variegatus), and 1 gray four-eyed opossum (Philander opossum). We found no evidence of predation on primates despite their abundance in the area and their importance to Harpy Eagles studied elsewhere. We observed no sloths in 605 km of line transects, a finding that suggests the inadequacy of transect data to estimate prey density for Harpy Eagles.

New tick records in Rondônia, Western Brazilian Amazon

In the present study, we provide new tick records from Vilhena Municipality, in the Southeast of the State of Rondônia, Northern Brazil. Ticks collected from a capybara, Hydrochoerus hydrochaeris (Linnaeus), were identified as Amblyomma romitii Tonelli-Rondelli (1 female), and Amblyomma sp. (1 larva). Ticks collected from a harpy eagle, Harpia harpyja (Linnaeus), were identified as Amblyomma cajennense (Fabricius) (16 nymphs) and Haemaphysalis juxtakochi Cooley (1 nymph). Ticks collected from a yellow-footed tortoise, Chelonoidis denticulada (Linnaeus), were identified as Amblyomma rotundatum Koch (10 females, 2 nymphs), and Amblyomma sp. (2 larvae). The present record of A. romitii is the first in the State of Rondônia, and represents the southernmost record for this tick species, indicating that its distribution area is much larger than currently recognized. Although both A. cajennense and H. juxtakochi have been reported parasitizing various bird species, we provide the first tick records on a harpy eagle. A. rotundatum is widespread in the State of Rondônia, and has been previously reported on the yellow-footed tortoise. The present records increase the tick fauna of Rondônia to 26 species.

Primeiro registro de Harpia harpyja para o bioma Pantanal, com dados sobre atividade reprodutiva

The first reliable encounter of the Harpy Eagle Harpia harpyja in the Pantanal floodplains is reported, with information on its breeding activity in the region, as well as some prey. A nest was found in August 2009, located in Barão de Melgaço County, northern portion of the Pantanal, with a 60-90-day-old eaglet. After a windy storm on August 30, the nest fell, causing the death of the nestling. In March 2010 another nest was located about 2.6 km distant from the first. We emphasize the importance of this record, and the need for a monitoring program to evaluate the true status of the Harpy Eagle in the northern portion of the Pantanal and nearby areas.

Sistema embarcado para monitoramento de harpia (Harpia harpyja)

Esta dissertação consiste no projeto e implementação parcial de um sistema integrado de monitoramento da ave Harpia (Harpia harpyja), espécie encontrada na Amazônia, Cerrado e Mata Atlântica. O sistema de monitoramento é estruturado em três etapas: coleta, armazenamento e transmissão de dados. A primeira etapa consiste na coleta de dados a partir de sensores, podendo detectar a presença de pássaros no ninho, também o sistema conta com o auxílio de uma câmera responsável pela captura de vídeo e áudio. A segunda etapa destina-se ao pré-processamento e armazenamento de todas as informações coletadas. A terceira etapa é responsável pela transmissão dos dados através de satélite, utilizando o Sistema Brasileiro de Coleta de Dados Ambientais (SBCDA). Além disso, foi realizado o desenvolvimento de um protótipo utilizado para o monitoramento. Técnicas de sistemas embarcados são expostas para o leitor e o processo de detecção desta espécie é avaliado.

Alongamento do processo estilóide (síndrome de Eagle): relato de dois casos

O alongamento do processo estilóide, ou síndrome de Eagle, representa uma afecção multifatorial com características inespecíficas na análise do quadro clínico e no estudo por imagem. A utilização dos métodos de imagem, em associação aos sinais e sintomas, é de grande utilidade na confirmação diagnóstica, mostrando a extensão do complexo estilóide, os músculos e ligamentos que o compõem e as estruturas adjacentes. O diagnóstico é firmado quando se tem a associação das informações clínicas com os exames de imagem. Os autores descrevem dois casos de alongamento do processo estilóide e seus aspectos de imagem, principalmente por meio da tomografia computadorizada.

Brook Trout Removal as a Conservation Tool to Restore Eagle Lake Rainbow Trout

Nonnative brook trout Salvelinus fontinalis are abundant in Pine Creek and its main tributary, Bogard Spring Creek, California. These creeks historically provided the most spawning and rearing habitat for endemic Eagle Lake rainbow trout Oncorhynchus mykiss aquilarum. Three-pass electrofishing removal was conducted in 2007–2009 over the entire 2.8-km length of Bogard Spring Creek to determine whether brook trout removal was a feasible restoration tool and to document the life history characteristics of brook trout in a California meadow stream. After the first 2 years of removal, brook trout density and biomass were severely reduced from 15,803 to 1,192 fish/ha and from 277 to 31 kg/ha, respectively. Average removal efficiency was 92–97%, and most of the remaining fish were removed in the third year. The lack of a decrease in age-0 brook trout abundance between 2007 and 2008 after the removal of more than 4,000 adults in 2007 suggests compensatory reproduction of mature fish that survived and higher survival of age-0 fish. However, recruitment was greatly reduced after 2 years of removal and is likely to be even more depressed after the third year of removal assuming that immigration of fish from outside the creek continues to be minimal. Brook trout condition, growth, and fecundity indicated a stunted population at the start of the study, but all three features increased significantly every year, demonstrating compensatory effects. Although highly labor intensive, the use of electrofishing to eradicate brook trout may be feasible in Bogard Spring Creek and similar small streams if removal and monitoring are continued annually and if other control measures (e.g., construction of barriers) are implemented. Our evidence shows that if brook trout control measures continue and if only Eagle Lake rainbow trout are allowed access to the creek, then a self-sustaining population ofEagle Lake rainbow trout can become reestablished
