Speaking the Language

I went to bed late last night, it was easily midnight or beyond, and as I lay there on the edge of sleep, I heard an unaccustomed sound. It sounded like…birdsong. I listened closely. It was, indeed, birdsong. And not just little chirps or the otherworldly radar sounds of an owl.

There were two birds, calling to one another, long, complicated tunes that sounded like they were being played on a glass harmonica.

My first thought was: Nightingale.

I thought of those lines from Shakespeare’s Romeo and Juliet:

JULIET
Wilt thou be gone? it is not yet near day:
It was the nightingale, and not the lark,
That pierced the fearful hollow of thine ear;
Nightly she sings on yon pomegranate-tree:
Believe me, love, it was the nightingale.

ROMEO
It was the lark, the herald of the morn,
No nightingale: look, love, what envious streaks
Do lace the severing clouds in yonder east…

Imagine knowing, eyes closed and in a darkened room, what time of day it is just by the type of birdsong on the air.

I thought to myself that I had no real idea what a lark sounded like, nor for that matter, a nightingale.

Rather, it was night time, the birdsong didn’t sound owl-like. It wasn’t the sharp chirps of the ever-present flock of sparrows that live in the vines on our house, and I know nightingales sing at night. Deductive reasoning, not actual familiarity.

The above video shows 3-D digital sound sculptures of nightingale and canary song, created by Australian artist Andy Thomas, who begins his work “by listening to the sound carefully, going for a walk, and concentrating on the sound.”

But do they sing in autumn?

Yes, apparently, because they are on a migratory route to the south for the winter.

Research has shown that songbirds share similar ‘gene products’ for vocalizations that humans use for speech. So what we hear as song might be, for the birds, a rich conversation, good as a book, engaging as a movie. Better, probably, because it’s theirs.

After all, other research has shown that dolphins call each other by name, using a ‘signature whistle’ to identify themselves, and using others’ signatures to call individuals. And let’s not forget the mice who ‘sing’ to each other in ultrasonic melodies, and have vocalization brain patterns that resemble humans – and songbirds.

Think of all the conversations we are missing because we either can’t hear them, or don’t speak the language, or have forgotten how to listen.

Massive anchovy swarms off the coast of California have kept marine mammals and their observers busy for the past couple of months. It’s not so much that there are more anchovy than usual, it’s that there are more anchovy gathered in one place.

According to this article, anchovy movement can be due to a number of factors – plentiful plankton, mild temperatures – and this year, the anchovy stars aligned over Monterey Bay. Their presence, telegraphed far and wide via whale song, has set off a feeding frenzy of seals, whales, dolphins, and the press.

Anchovies and other small fish are known as ‘bait fish’ or ‘forage fish’, and form a key element in the marine food chain for mammals and the larger fish that humans prefer to see on their dinner plates. Some have recommended that humans switch away from the larger fish, which are being hunted by vast fishing fleets, to these smaller forage fish for human consumption.

Currently, we fish bait fish for use as feed to the other animals we prefer to eat – pigs, chickens, salmon. The ratio of forage fish feed to salmon, however, is around 5:1. Not very efficient. But the smaller fish, which tend to be oily, just aren’t popular for human consumption.

Anyway, the whales do exactly what human fishermen when they come across a bounty like this – they keep fishing until they’re full, or the fish are gone.

Here’s a very cool short clip, created by Robert Hodgin for the Auckland Museum, of how a bait ball works (in this case, sardines).
