A few nights ago, around midnight, we heard
something that reminded me of one of the Random Acts of Culture. Maybe you saw
the YouTube film of Macy’s department store in Philadelphia, suddenly
transformed by anonymous singers who were performing the Messiah. This was a
little like that: suddenly, through the cold, silent night, we heard singers,
two bright voices, harmonizing in an exquisite and nerve-wracking duet. Their
song was eerie and haunting, lunar in its cold loveliness. The night was
transformed.
Coyotes, of course. Cornwall has an active
resident population. My cousin Fred Scoville told me that a pack of them took eleven
of Thalia’s geese in one night. Which sounds like a good-sized pack, though it
was probably only one pair of parents and their pups. Connecticut coyotes hunt
in packs only until the pups are grown, and then disperse. Coyotes are monogamous, and the main social
unit is the mating pair.
The coyote (canis
latrans) is a medium-sized member of the Canidae family. Originally from
the western plains, they’ve moved east, breeding with big Canadian wolves, so our
Connecticut coyotes are slightly larger than their western cousins. They’re beautiful
animals, with luxurious bushy coats, slender pointed noses and long prick ears.
They’ll breed with dogs, though coy-dogs
are rare. (Mixed offspring rarely survive, since pups need both parents for
support. Also, like mules, coydogs are often infertile.) Coyotes are
opportunistic, and will eat almost anything, which is why they’re so successful
as a species. They’ll eat garbage, insects, mice, rabbits, small deer - even small
pets, I’m sorry to report.
And they’re singers: they have at least ten
different variants of vocal sounds, including growls, woofs, barks, howls and
yelps. Woofs and growls are short-distance threats, barks and bark-howls are
used in greeting, lone and group howls provide location information during
separation, and a group yip-howl occurs after a reunion.
The song we heard the other night was clear, passionate
and very potent. At first I thought they were hunting. I’ve heard them
sometimes in full cry, voice after voice declaring itself, yodeling up to the
top of the scale, then drifting into strange, four-part harmony. But this was
different: discrete, full of sudden energy, rising at once to full pitch, and
then, just as suddenly, stopping.
Coyotes breed once a year. In Connecticut, this
happens between January and March. The
female is only in estrus for 4 to 15 days, so there’s a small window of
opportunity. According to my book, there’s one other occasion on which coyotes vocalise:
before copulation, the pair may sing a duet.
I don’t want to start rumors, but I think last
week our local coyotes had a date night.
