Atlas in VN 3060

Just as the year last, the census realised for the Atlas of wintering birds of Spain in the square VN 3060, has given very low results of records of birds.

To compare, the SACRE of winter in the VN 4040, with eight routes of 15 min. 29 different species of birds have been observed, and in the 22 routes of the Atlas of wintering birds with 15 min. each, I have been observed 22 different species.

The great difference is in the different types from habitat.
This square has an average of 900 m., and is cold.
The vegetation in this high zone is very not varied, and great part of her is occupied by gorse and pasture.

I do not know the causes of the absence of birds, but it is a zone in which there are not many shrubs with berries, and this without a doubt avoids the presence of birds like Thrushes, Hawfinch or Bullfinch.
Arable lands do not exist either, in which they are accustomed to see finches mainly.
This year the detected species have been very few, here you have the list of birds for this year:

Griffon Vulture, Common Buzzard, Red Kite, Eurasian Sparrowhawk,
Meadow Pipit, Blue Tit, Great Tit, Crested Tit, Coal Tit, Long-tailed Tit, Mistle Thrush, Blackbird, European Robin, Wren, Common Chaffinch, European Nuthatch, Short-toed Treecreeper, Spotless Starling, Carrion Crow, Jay, Magpie, Southern Grey Shrike.
