Dear Azkha
Thanks for your logo entries. In particular, the bird ones are excellent. I would not spend more time on the snake G ones. While they are subtle and well thought through, I think they would struggle to be a distinctive enough image for the site.
The bird-based logos are excellent. Birders will be a large part of the user base, especially as the site builds momentum. Also, birds are globally recognisable and this bird image would resonate with people wherever they live.
Among the bird logos, I really like the leaf/crest on the bird. I also like the two tone version of the bird. and the fine white line breaking the face tones up in entry #22.
I do worry a bit about how entry #22 would translate to a black background but perhaps that is easy to address by using various colours and tones for the logo, depending on the backgorund.
Regards
