Confusingly, like Laguna de Medina, these lagunas aren’t that close to the settlements after which they are named, Lebrija. Perhaps they’re ignored too because they’re just over the border from Cadiz in Seville Province and thus well away from all the well known sites in the latter province. In fact, they’re just a few km further along the track from northern exit from the Lagunas de Espera where it crosses the Gibalbin-Cabezas road.
Despite the tamarisk and reed clogged margins, with care you can get a reasonable view over the pool. Here I’ve had decent views of White-headed Duck, Red-crested Pochard and Black-necked Grebe, Whiskered Tern and Purple Heron. The presence of numerous Coots suggest that Crested Coot may well be present too – it’s certainly worth the price of a short detour. However, arguably, it’s those tamarisks that should hold your attention. They often have a large flock of Spanish Sparrow which, if no longer as uncommon in the area as once they once seemed, remain a good bird to find. More interestingly, they also host a healthy population of Olivaceous Warblers. Most trip reports mention this species only in the context of a visit to Laguna de la Mejorada (aka - "Lago de Diego Puerta") which is near Los Palacios y Villafranca in Seville Province. To a point this is understandable as it is handy for Brazo de Este and has the bonus of also being a site for Rufous Bush Chat. However, this ‘blinkered’ approach has meant many other sites go unvisited and undervalued. In Seville Province and, to only a slightly lesser degree, I’ve found Olivaceous Warbler to be not uncommon in larger clumps of riverine or lacustrine tamarisks. It’s a matter of knowing where to look. Still more interestingly the recent Spanish Atlas suggests that there is a concentration of Rufous Bush Chat along the Seville-Cadiz border just around these lagoons.
So instead of following the crowd and going to Laguna de la Mejorada, why not try a little exploration and give the Lagunas de Lebrija a try? Better still do a little exploration before you leave home via GoogleEarth and find an entirely new site yourself!
