i've been toying with the idea that the reason why a lot of the new names in stormclan's folly seem strange or out of place is because the ancient clans are still transitioning from old tribe-era naming systems to the more modern naming systems that we know of today.
thrush's call → thrushcall → thrushsong
raven's cry → ravencry → ravensong
hunting heart → huntheart → ____pounce or ____leap?
floating weed → floatweed → floatstem, floatbranch, etc
either way, i really hope that as the main series continues, we see suffixes like -call and -cry make a comeback to diversify bird names. i feel like we have an abundance of -wings, -flights, and -feathers. i also like the idea of -screech being introduced (ex: owlscreeh, crowscreech)
i also have a headcanon as to why cats like crowflight, alderbranch, and icefoot seem to have strange names in this era for their pelt descriptions. with the deforestation in skyclan's territory, the species of crows (brown in coloration) were driven out. i also like to think that alder trees with very dark bark existed in parts of all the clans' territory, but were predominantly based in skyclan's territory. also, i think that icefoot has white paws or some kind of prominent lower-body white coloration. i myself have an OC named frostfoot (a black tuxedo she-cat with ice-blue eyes)
→ as a side note, i am very excited that names i've used for OCs in the past (crowflight and mudsplash) have made their way into the main warriors series. i've been dying to see mudsplash in particular being used as a name since forever
Those are very good theories! And I also share your hopes about diversifying the names and those suffixes coming back.
I’m glad you got some OC names in there! Mudsplash is a particularly cute name so it is great to see that in canon
