DannyMilksI just noticed this discussion...to answer your question about birdwatching...from the standpoint of a person who has watched and identified birds over the years(binoculars and bird book only),perhaps a true avid birdwatcher would be interested in recordings,books or calls. As a separate category ....there is a lot of overlap...
