I address the pronunciation here, not the etymology
of the root words in the names:
Pronunciation in English of scientific names do
have certain broad rules. Most people do not know them, or if they do they
choose to ignore them and pronounce the words in a way that makes sense to them.
That's OK of course. Too often we also do this with English or non-English place
names, so people end up pronouncing a word like the locals do or not. Whatever
works for each person is used.
But, I am like you. I'd like to know the
pronunciation that is a standard under the generalized prevailing rules. I
understand that Latin scholars disagree on how Roman Latin was pronounced by
speakers during the Roman Empire heyday. There seems to be two schools of
thought; so even the scholars disagree on how Latin was once spoken as a
living language. Yet I, like many others, took a couple years of Latin in a
Maine high school eons ago, and consequently, am sensitive to issues of
pronunciation.
The broad rules that seem to apply in prounouncing
scientific words as the old ornithologists used to (keeping in mind that people
like Coues, Ridgway, Zimmer, and others, used scientific names much the way we
do English names of birds) are as follows:
(1) All syllables get pronounced, including ones
that sometimes are silent in English pronunciation. For example, for the name of
a Yellow Warbler subspecies, "parkesi" (a word that memorializes Ken Parkes, who
was a professional ornithologist at the Carnegie Museum, Pittsburgh PA) is
pronounced "par-KEES-eye," not "PARKS-eye," not PARKS-ee" (although these last
are NOT "wrong"). In anglicized pronunciations as used here in the US at
least, "i" as an ending is pronounced "eye" not "ee."
(2) Some standard endings such as "-idae" for
family names, e.g., Parulidae, Emberizidae, etc, are pronounced in US English at
least as "-ah-dee," not "-ah-dye," which is the way I learned the diphthong "ae"
("eye") in my Latin class. The ending "-oidea" contains another diphthong "oi"
get the sound "oy" in English.
Accents are always a problem: The old
ornithologists followed an accent placement rule, which varied a little bit, but
generally is: for two syllable words, accent on first syllable; for three
syllable words, accent goes on the middle syllable (sometimes on first, but
whatever sounds best and flows most easily is fine); in words with four or more
syllables, accent usually goes on the second or third syllable from
last, depending on what seem to flow most easily as a sound. The old AOU
Check-list 5th edition (not more recent ones) shows the accepted placement of
accents. For example, in the name for the Brown
Thrasher, Toxostoma rufum, the 5th edition has the
name with a diacritical (in this case "accent" mark) mark over
the 2nd "o" to indicate accent on the third syllable, as
follows: "tox-OS-tomah." Yet a variant pronunciation that one may hear is
"toxo-STOME-ah." The early ornithologists would use the former
(they spoke Latin and used it as a scientific language and standardized the
pronunciations to aid communication), while the 2nd is NOT "wrong," only
different. The trivial or specific epithet (keeping in mind that the "species
name" is a binominal [not binomial] phrase - both words together) was
indicated in the check-list with an accent mark over the "u" in "rufum,"
signifying that the first syllable gets the accent, as in "ROOF-um." So to
summarize, the thrasher's scientific name would properly come out "Tox-OS-tomah
ROOF-um." The formal pronunciations as used by the old Latin-focused
ornitholgists also are shown as early as Eliot Coues' Key to North American
Birds (5th edition, 1903).
Now to the new parulid name that you bring up,
"Oreothlypis peregrina:" Analyze each word separately and count the
syllables: 5 in the genus word and 4 in the trivial epithet or word.
Generally the accent would go on the 2nd or 3rd syllable in both
cases. So the first word is "Or-ee-oh-THLEYE-pus" and the 2nd is
"pear-ah-GREYE-nah." Sometimes people may pronounce this last word as
"pear-ah-GREE-na" as well - either is fine, but usually an "i" is pronounced as
an "eye" and not an "ee." AOU-5th edition confirms the trivial word with an
accent mark over the "i" to indicate emphasis on the "'gri" syllable.
The original generic classification for the
Tennessee Warbler, Vermivora (4 syll) get the accent on the third
syllable "miv," i.e. "ver-MIV-or-ah"
I guess my general recommendation
would be to break the word up into syllables and try the word out to yourself to
find a syllable flow that seems to come naturally and smoothly, making sure to
pronounce ALL the syllables. In longer words, try accents on 2nd or 3rd syllable
from last and see what sounds best to you. GO WITH
THAT.
Good luck and best wishes.
