In an environment as estepario and, apparently empty for bird watching, the valley of the río Blanco with the presence of water, small woods, grassland and crops, increases the presence of various species.
May It would be the ideal month to make a list of birds more than considerable. If we choose the path of Layna grassland of Urex we have a succession of birds in agricultural environments, forest and moorland for, it is not unusual for example be walking down the road and hear the Dupont's lark they are singing in the upper moor, as long as we start early in the morning.
On clear precisely slopes that fall moor see Spectacled warbler and Dartford warbler, Northern wheatear and Black-eared wheatear and the singing of the Ortolan bunting. Alongside these species, poplar groves and pastures of the river are home to a varied catalog of birds including species such as northern root Song thrush and the Red-backed shrike. Density Yellow wagtail it is notable, next to Cetti's warbler and the Zitting cisticola. In the pasture we can see Water rail, Mallard, Western marsh harrier and the Montagu's harrier. Corn bunting, Common stonechat -and Whinchat in steps- goldfinches, linnets and Woodchat shrike completed our list of observations. The oaks of Urex, the common Chaffinch and the Bonelli's warbler are the dominant species sharing space with European turtledoves and Subalpine warbler and Western orphean warbler which also appear in a number.
The high altitude of the area makes June and early July months are also very suitable for observation. In July there will be nourished family groups almost all species. Around Layna they are particularly bustling with swifts, swallows, House sparrows and Rock sparrow, Common magpies, Collared dove, Spotless starling, Crested lark and Thekla lark. The Western marsh harrier already have chickens fledglings, and the cenizos, Booted eagle, Common buzzard, Common kestrel and Short-toed eagle, will be the most common raptor.
In August September the valley and surrounding areas are good places to see migrating birds, especially raptors: large flocks of Black kite and European Honey buzzard, especially, but also groups European bee-eaters and other species.
And autumn-winter, you will have a moment of relative calm, especially in the surrounding moor, where many species will disappear. In the transition zones between moorland and forest areas, they will arrive Redwing and Fieldfare, remaining good sides of Rock sparrow and Common chaffinch. On the slopes also if you have been good year of rearing Red-legged partridge, we can see good sides. It will not be strange to see Hen harrier and the Yellow hammer, who come to the valley to also spend the winter.
