Yesterday I added 30+ 2CY fuscus, pictures by Hannu Koskinen from Finland. Birds in June and July of which many typical birds but also quite a few slow moulting birds. Also added the article about accepting unringed 2CY birds when they meet certain criteria far beyond what we have scored in western taxa.
