I've been doing this for the last 14 years. It is very difficult to put them into order. But this is something that only you have been doing, so the data you have must be valuable on an international scale. Tufted puffins can be observed around the island. Identifying birds is important.
Identification is the basis for conversation regarding birds.
One of the things that is fun about bird watching is communication with fellow bird watchers. This requires knowing what you have seen. Otherwise it will be difficult to trust what is being said, and the conversation itself will be vague. It is important to be able to state what bird of what species a bird watcher was observing. That is the advice from Kataoka to new bird watchers.
