Maybe "Big" Legendaries Per say only appear once and only have room for one in your inventory, but have set locations on the map, whereas duo/trio/roaming legendaries have a really low find percentage.

By this I mean that pokemon like Groudon or Kyogre have a certain chance of spawning on their set locations on the map, which would be the caves that appear at certain times. Like 1/10 or 1/50 or something and once every certain set time period game wise. But before walking in the player should expect them to be there to be ready to Take them on or catch them, because if they fail they won't be eligable for a second chance. However in the case of the shiny big legendaries perhaps it would count as a completely new sticker on the groudon tab, that along with the already present 1/50 chance of spotting in the first place, another 1/500 or 1/1000 chance of finding a shiny variation, some person who really cares about finding shinies could just walk in and out over and over hoping by some rare chance that they get it. But if they fail to catch this legendary the first time they can attempt again later, but they may only obtain One member of it's species at a time.

Smaller legendaries like the birds, latis, and dogs should be more as in Roaming and very rare. Like in areas you find stickers for other pokemon, a 1/100 chance every game day one appears, maybe more or less. If there is a map gui you could make it so legendaries currently on the map have a star above their heads. And you would head to that area. These you could obtain multiple of, as such that pokemon like the Latis are clued at in the Anime to have more then one of their species.
