Adding the Dowitcher – a comparison of memory aids

A small wading bird landed in a lake and started a twitch unlike any before in Australia. Social media went into overdrive, as bird watchers scrambled to travel for hours in the hope of a glimpse of the one long-billed dowitcher among the sharp-tailed sandpipers at Lake Tutchewop, between Swan Hill and Kerang in northern Victoria.

Why all the excitement? This is the first record ever of a long-billed dowitcher in Australia. A new tick, a lifer, for every twitcher who managed to see it. They turned up in droves.

Readers of this blog will know that one of the memory challenges I have undertaken is to memorise the 407 birds in Victoria using a memory board. The list in my head is in taxonomic order with family names in Latin. So what happens when a new bird inserts itself in the middle of one of my existing families?

If I’d used one of the standard mnemonic methods, such as creating a rhyme for all the birds, I would have real trouble adding in a newcomer. What would happen if they found a new king between Richard I and John and needed to add him into the famous mnemonic for the monarchs of England:

Willie, Willie, Harry, Stee,
Harry, Dick, John, Harry three;
One, two, three Neds, Richard two;
Harrys four, five, six… then who? …

More complex memory methods, such as using an acronym or a linked sequence of items (the Link Method)  would also let me down here. It is very difficult to add in a new comer into the chain.  By using the complex of indigenous methods as I do, adding the dowitcher was a breeze.

My memory board – a perfect size to hold in one hand.

I describe the way I memorise the birds in the post Memorising Birds. Each bead on the memory board (based on the African lukasa) represents a family. I traverse the beads in a set order. I can sing the 82 family names: Dromaiidae, Anatidae, Megapodiidae, Phasianidae, Podicipedidae … 82 of them. As I sing them, I can see the memory board in my mind, I know it so well. Mythological stories associated with each bead tell me how many species there are in the family. If there are more than 4, I use a journey, the method of loci, to memorise all the members of the family, again in taxonomic order. I had difficulty believing this would work when I first read about the lukasa. I now know that it is amazingly effective.

I had to add a new bird, the dowitcher. It is Scolopacidae, along with the 25 sandpipers, stints, godwits and the like in the family. The house along my sandpiper songline with the godwits and sharp-tailed sandpiper (the birds most like the dowitcher) has two small palms in front which I have linked to the two godwits. I needed something new, and soon noticed a third small palm, mostly hidden by other bushes. That palm was, within a minute, linked to the dowitcher. Hear the word ‘dowitcher’ now and my brain instantly sees that palm which allows me to locate the bird in the taxonomy. Into the ‘mythology’ I have already created around that location, I encode everything I learn about the dowitcher.

Using a range of mnemonic technologies system reflects the way non-literate cultures encode such a vast store of information about animals, plants, laws, navigation, astronomy, timekeeping and all the other practical knowledge I talk about in Indigenous mnemonics. It seems as if it would be confusing, but it isn’t. It seems as if it is more work than just memorising by constant repetition, but it is far far easier and far more robust.

I love this stuff!
