About the pronunciation of pileated: long and short i sound are BOTH accepted, correct pronunciations. Just to keep everyone happpy, I use a long i before noon and a short i after noon. Same rule applies to Missouri/Missoura options.
There are other pitfalls, for example:
Ibis sounds like eye-bis, not eeebis
Yes, egret can work more than one way, but the more common is with accent on first syllable.
Northern (or Tropical) Parula is often pronounced Pa RU la (accent on second syllable), but PAR oo la (accent on first) is preferred by many and is closer to the root word.
Bird names honoring people can be a real bugaboo. Examples:
Sabine's Gull. Not pronounced like the river in TX/LA, but as the man pronounced it, it rhymes with satin.
Bachman's (as in sparrow and presumably extinct warbler) has the same a sound as in satin, not the soft a of caw.
As for any bird, any way you say it, it's the observing that is fun.
Phalarope
