These look like various breeds of domestic geese and ducks. I'm not 100% sure, however, the ducks look like Rouen drakes and the geese look like Pilgrims and maybe Toulouse, but they could easily be mixed breeds.
Yes, I believe it's a good thing. I have registered too. Sometimes certain species and areas are under-represented. I had recorded a sighting for the Wood Nymph that apparently had not had a registered and confirmed sighting since 1985. It all depends on people getting online to help keep track of which species are seen where. I'm glad you took the time to participate. :)
