List of potential hotspots of AIV infection detected in our study.

<p>These sites correspond to sampling occasions (top) at which the number of AIV-positive birds was above the threshold number of birds for which the hypothesis that prevalence is lower than 10% could not be rejected (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0046049#pone-0046049-g002" target="_blank">Figure 2</a>). Sampling conducted in different years at the same sites during the same months and on the same species (below) detected a low number of AIV-positive birds.</p>a<p>. African jacana <i>Actophilornis africana</i>, Kittlitz's plover <i>Charadrius pecuarius</i>, Little stint <i>Calidris minuta</i>, Blacksmith lapwing <i>Vanellus armatus</i>, Slender-billed gull <i>Chroicocephalus genei</i>, Curlew sandpiper Calidris ferruginea, Wood sandpiper <i>Tringa glareola</i>.
