I was observing rooks from my balcony this spring and made a sketch of this rook in march but finished only in may. There where hundreds and thousands migrating everyday in 2 weeks period. I wanted to show only the head, because of the tremendous beautiful bill the bird has. 

If you would like to ask me any questions about my bird illustrating skills or would like to work with me, please contact me directly the_tourist@mail.ru.

Thank you and enjoy!
