SACRE in Winter

This it is the first year that I realise the route for the new program for the follow-up of birds of SEO BirdLife, the follow-up of common birds in winter. (More here)
The squares it’s the same that I realise in spring, VN 4040.
The route is simple, and I have chosen to realise it by two zones easy to walk and very pretty, the pastures of the Valley of Zamanzas and the footpath GR 99 throughout the river Ebro.
In this zone the river Ebro has very well conserved banks, where the alders abound, ashs, poplars…
A good number of birds and species, 29, but certainly throughout the years this will change.

Here you have the relation of species seen in two hours:

Mallard, Grey Heron, Griffon Vulture, Common Buzzard, Common Kestrel, Blue Tit, Great Tit, Long-tailed Tit, Fieldfare, Song Thrush, Mistle Thrush, Blackbird, European Robin, Wren, European Serin, Eurasian Bullfinch, Hawfinch, Common Chaffinch, Eurasian Siskin , Green Woodpecker, Blackcap, White Wagtail, Dipper, Spotless Starling, Red-billed Chough, Carrion Crow, Jay, Eurasian Nuthatch, Wood Pigeon.
