| predicting west nile virus seroprevalence in wild birds in senegal. | west nile fever epidemiology is complex, and the role of birds in the maintenance, amplification, and dissemination of the west nile virus (wnv) remains partially unknown. in 2003, a serological study was performed in senegal, where west nile infection is considered endemic. the goal was to identify potential reservoirs of wnv among bird species present in the ferlo area (northern senegal) and the senegal river valley, and to screen the ecological factors possibly related to west nile infection. ... | 2009 | 19196131 |

| habitat use and body mass regulation among warblers in the sahel region during the non-breeding season. | migratory birds face significant challenges across their annual cycle, including occupying an appropriate non-breeding home range with sufficient foraging resources. this can affect demographic processes such as over-winter survival, migration mortality and subsequent breeding success. in the sahel region of africa, where millions of migratory songbirds attempt to survive the winter, some species of insectivorous warblers occupy both wetland and dry-scrubland habitats, whereas other species are ... | 2014 | 25426716 |
| evidence for egg discrimination preceding failed rejection attempts in a small cuckoo host. | given the high costs of avian obligate brood parasitism, host individuals are selected to reject parasitic eggs they recognize as foreign. we show that rejection may not necessarily follow egg discrimination when selective removal of the parasitic egg is difficult. we studied egg rejection behaviour in a small host of the common cuckoo cuculus canorus, the eastern olivaceous warbler hippolais pallida, by experimental parasitism with model and real non-mimetic cuckoo eggs and video recordings of ... | 2009 | 19126530 |
