I would like to compare egg pattern between cuckoo and host eggs to measure pattern mimicry. In the past I have used a tool developed by Troscianko and Stevens (2015) to do this, but I was curious to know if there were any other tools out there that could be used to compare similarity in egg pattern between different bird species? Also, if anyone has suggestions about a good way to measure egg shape, I would be happy to know that too!
