Now, to the point:
1) It works, but it's more like looking at a picture.
2) 5 birds is a lot for anyone. And again, you're connecting two pieces of evidence into one. You could just as easily break down your own argument into details. ;)
3) Oh yes. It's the most obvious thing you could come up with.))
At least you could have suggested it to Neirtz, since Drake = Dragon, and it's also an animal. And here, in the very first night, there's such an obvious clue... well, well, as they say.)))

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
