As every year I have finalized program SACRE of this season, two squares that I made a route detecting the present birds, to determine throughout the time the variations of the populations.

In square VN4040, with data from 1999, I have located to this season a total of 64 different species.
Altogether, during the 9 years that I take making this grid, I have located a total of 91 species.

Species that have been detected, this year, for the first time, in VN4040.

Great reed Warbler (Acrocephalus arundinaceus)
In square VN3040, I take to only two years making the census, have located to this season 62 species.
