Winter. Although we have said it is a cold zone is no less true that there are many anticyclonic days, splendid sun after morning frost, where there are species of interest that can make pretty interesting visit. Here are not as rare species Brambling, the Yellow hammer, the Hawfinch, Eurasian siskin, thrushs... that combine heterogeneous environment. In recent years they have also shown up here Spanish sparrow. In winter they make erratic movements and can be found roosting around Laguna de la Sima, with over one hundred copies.
If the winter was rainy, the existence of the wetland in Conquezuela is a guarantee for the presence of anatidae, especially Common teal, Northern pintail and Mallards which can be seen from the first row time, as the weeks go on January and February, from Grey heron, storks, some waders first step as Green sandpiper and sides of Northern lapwing. Common crane and Greylag goose also they cited here, although to a lesser extent than in other county wetlands Barahona.
March April. Waterfowl are still the protagonists. Shorebirds are the most abundant as add plovers, redshanks, sandpiper and follow the Northern lapwing until the wetland is emptied of the whole, at the beginning of the month May. Attention is then focused on the breakwater birds in small cut sandstone near: Egyptian vulture, Common kestrel, Crag martin, Rock sparrow, Black redstart, Common raven, Red-billed chough, and the Rufous-tailed rock thrush and Blue rock thrush.
Laguna de la Sima is not yet dry in this period and host a small population of Mallards, Little grebe, Eurasian coot, Water rail, Common moorthen and Great reed warbler.
May June. Oak forest nearby are slow to take leaf. Sometimes it is not until late May when this event occurs. Forests are regenerating, not many mature specimens, but they harbor a species interesting with certain dyes "northerners". In recent years can be seen here species like Tree pipit, the Song thrush, the Eurasian nuthatch and the Red-backed shrike.
It is very curious that, next to this northern expansion, There are some species that arrive from the south as the Sardinian warbler and the Spanish sparrow. If we extend the visit any of the nearby moorland areas, with Thekla lark, Greater short-toed lark, Tawny pipit, Spectacled warbler and Black-eared wheatear, the list of species present is more than considerable.
