I agree with Haytham Senbill's reply. Crucial points for identifcation are out of focus. Furthermore, when trying to identify ticks, start out with keys for your part of the world, and ticks collected on known hosts, not probably from migratory birds. Which continent are you on?
Thank you for your suggestions, I have already identified the ticks their Hyalomma lusitanicum. nymphs... the photo was taken with the cellular since I was in a hurry... The host which they are from is eagle. I'm from Portugal.
