I thougt the pictures will appear with the name (numbers) I gave them. So you could know wich one is, just follow the order I wrote (ex. first picture is 1.A; second is 2.A, third is 2B, and so on...). Thank you! 

When we are dealing with wild animals it is important to have the adult to confirm identification. Only with egg images it is difficult to say. Concerning coccidian pictures, it's possible to sporulat them, putting the sample in a 2,5% potassium bicromate, mising them to oxigenat every day. With the pattern of sporulation it is possible to discover the genus at least.

As Carolina Chagas commented you, it's very difficult to make a correct identification of coccidia when sporulation has not been made (and therefore no description of the sporozoite) and no oocyst measures (length and width) have been provided. Without this information, an alternative to identify coccidia species would be the use of genetic techniques (as long as this sequences have been previously uploaded in GenBank which it is not very common). In this sense could be use genomics techniques to identify OTUs (operational taxonomic units), but this could get out of the focus of your work besides being more expensive.

With respect to the identification of the oocysts/eggs requesting, I think oocysts found in lesser kestrel (3 A -B) are most likely the genus Caryospora (several potential species could be found in this raptor as e.g. C. neofalconis, C. falconis, C. heryae, C. kutzeri ....or else the recently described in F. tinnunculus as C. peneireiroi). But as I have explained above, it is almost impossible to reach a specific identification without sporulation or genetic.

Kind regards!
