What would be interesting would be to have the option to list birds that do not appear in the main list of species seen, for example I would like to include heard only, but I would not want this to be added to my main species seen list. Similarly I might want record untickable views, White-bellied and Philippine Kingfisher spring to mind, both birds I have seen as fast moving blurs of colour, which I would not add to my life list, but would be interested in recording. The nearest that Bird Base, which I use, has, is an uncertain sightings button, which can be included or excluded from lists.
