Small, brownish bird with reddish spot around eyes ![Three pictures of the bird: head, back and in flight]( This bird was seen in the Bourgoyen-Ossemeersen nature park, Ghent (Belgium) on December 3rd 2016. It is about the size of a common chaffinch. We couldn't get a very good picture of it, unfortunately. What is the species of this bird?

It's a Chaffinch (Fringilla coelebs). From the first picture you see the greyish head and orangish chick. From the second picture the typical whitish/greenish wing bars. From the third pic the bricky belly.
