In winter you can discover the strange feeding habits of the Southern Grey Shrike (Lanius meridionalis) or learn a few "soloist" birdsongs (Mistle Thrush, Robin), before the mega-chorus of spring with the arrival of so many migrants.
Here in the Tierra de Pedraza you can admire the Spotless Starling (Sturnus unicolor), typical of the Iberian Peninsula and resident all year round.
