Close enough for eggs, anyway. Compatibility wise. Don't think there is enough crossover for all that many unique or interesting egg moves though. At least I haven't heard of that many birds picking up sound moves from a -bat parent. Might depend on how strong actually.
[ a couple things get stuff like Supersonic, maybe, it's even learned naturally for some,
but it's what, just the Swellow line, and he thinks maybe Chatot or Toucannon that gets Boomburst via Noivern...? Scrappy Boomburst is a thing some trainers like to bring to the battle lines, and Chatot would just make sense given how well they can mimic sounds and cries. ]
