White-fronted Chats

Observations of the White-fronted Manakin (Pipra Serena) in Suriname

The White-fronted Manakin (Pipra serena) is found in the highlands of the Guianas, southeastern Venezuela, and adjacent northern Brazil (Haverschmidt 1968, Meyer de Schauensee and Phelps 1978). Pipra serena is a small manakin (7-8 g) of the P. coronata species-group (Snow 1979). Males are distinguished by their velvety black plumage with patches of white on the forecrown, light blue on the rump...

Current Status and Management Challenges For Tule White-Fronted Geese

Lesser White-fronted (Anser erythropus) and Greater White-fronted (A. albifrons) Geese wintering in Greek wetlands are not threatened by Pb through shot ingestion.

Fecal lead (Pb) levels were investigated in the threatened European population of the Lesser White-fronted Goose (LWfG, Anser erythropus) and of the non-threatened Greater White-fronted Goose (GWfG, Anser albifrons) wintering in two wetland areas in northern Greece in order to assess the potential risk from Pb exposure. Fecal, soil and food plant samples were analyzed. Levels of Pb were normali...

Chats for all: A user survey to improve chats' interaction

The use of chats is being increased; however, they cannot be used by everybody because they present accessibility barriers. Previous research works have solved some of these problems, but accessibility problems related to the user interaction have not been solved yet. This work is part of a research which main goals are to provide a model-based accessible chat and a development process strategy...

Avian cholera exposure and carriers in greater white-fronted geese breeding in Alaska, USA.

We conducted a 3-yr study (2001-03) on greater white-fronted geese (Anser albifrons frontalis) breeding in Alaska, USA, to determine the exposure of this population to Pasteurella multocida and the potential role of these birds as disease carriers. We tested sera from nearly 600 adult geese for antibodies to P. multocida serotype 1. We found a low prevalence (<5%) of positive antibodies in adul...
