There is a Dutch Facebook group for determination of plants and animals, people post pictures there and there is always a real expert around who can actually identify your bird feather / tiny spider / insect / fungus / etc often down to the exact species (out of 800 in some group of beetles, say). It's a wonderful group to lurk in.
