  abstract = {{W}est {N}ile fever epidemiology is complex, and the role of birds in the maintenance, amplification, and dissemination of the {W}est {N}ile virus ({WNV}) remains partially unknown. {I}n 2003, a serological study was performed in {S}enegal, where {W}est {N}ile infection is considered endemic. {T}he goal was to identify potential reservoirs of {WNV} among bird species present in the {F}erlo area (northern {S}enegal) and the {S}enegal {R}iver {V}alley, and to screen the ecological factors possibly related to {W}est {N}ile infection. {S}erological data were analyzed using a generalized linear model. {S}tatistical association between ecological factors and the risk of infection were then modeled to derive a species-specific risk. {A} cross-validation was conducted. {T}he overall observed prevalence rate was 5.5% (n = 422). {T}hirteen bird species were found positive, from which five were migrating: {L}anius senator, {A}nthus trivialis, {H}ippolais opaca, {J}ynx torquilla, and {C}ercotrichas galactotes. {T}he nesting type in resident birds was positively correlated with the risk of infection (odds ratio [{OR}] = 11, p 5 = 0.0003); the gregariousness level of birds appeared as a protective factor ({OR} = 0.3, p = 0.01). {T}he predicted prevalence varied between 1% and 39% for resident species and between 1% and 7% for migrating species. {R}esults of model internal validation were satisfactory at the individual and species level. {H}owever, more field and experimental investigations are needed to confirm these preliminary results and help target the future research and surveillance in {S}enegal.},
