Zoologists have often given our fauna scientific names which are interesting, strange, amusing or even downright rude.

This blog will , over time, systematically dissect the literal meanings behind some of our British animals' scientific names.
I'll start with birds and move onto insects and other animals.

This blog began life on November 16th 2012. I will add to it regularly.

Brent goose

Brent goose 
Branta bernicla 
[Linnaeus, 1758]

The brent goose is another member of the Anatidae family (swans, ducks and geese) and like the alien Canada goose, a "black goose" like the barnacle goose also - one of the Branta genus of geese as opposed to the grey Anser genus.

I've included the brent goose in my list of zoological nomenclature explanations here as its scientific name might confuse the unsuspecting...

Whilst dissecting the generic name of the Canada goose here, I've explained the stem of Branta (old Norse brand meaning singed black) but what can bernicla mean then?

Rather like the geese we call barnacle geese (similar-looking but unrelated geese, see below) medieval folklore would have it that the brent goose appeared from nowhere in the late autumn - born as goose barnacles (the barnacle was actually named after the goose, not the other way around).
This is because no-one tended to see barnacle or brent geese breeding or young - this all happened in the arctic.
It seems strange to us now that this was believed, but if you look at a goose barnacle, with its feathery feeding appendage extended, you could almost see what those medieval folk meant and understand why they thought goose barnacles were the young geese.

So bernicla literally means "barnacle" in Latin and the scientific name for the brent goose (NOT the barnacle goose), literally means:
the "singed goose that comes from a barnacle".

But what about the bird that we refer to as a "barnacle goose" - it can't have the same scientific name as the brent goose can it?
No... it doesn't. What we call the barnacle goose is referred to scientifically as Branta leucopsis - which literally means the "singed goose with a light white face". Far more sensible than the "singed goose that comes from a barnacle" don't you agree...?

Canada goose

Canada goose
Branta canadensis
[Linnaeus, 1758]

The Canada goose, even though being an alien invader to the UK (first introduced to St.James' Park as a North American addition to Charles II's waterfowl collection in 1665) at least gives me an opportunity to briefly start to discuss the "black geese" scientific names.

The so-called "black geese" all have solid areas of very (very) dark grey or black in their colouration - mainly their bill and feet/legs (but also often in their plumage) and all the "black geese" belong to the Branta genus of geese, as opposed to the Anser genus (grey geese), which have orange or pink feet and bills.

Branta geese as far as us Brits are concerned consist of the Canada goose, the barnacle goose and the brent goose.

Branta (and indeed "brent") has a stem in old Norse - brandgas meaning "burned goose" (singed black goose)
Canadensis is new Latin for "from Canada".

Therefore, the Canada goose has a scientific name composed from old Norse and Latin stems which literally means:
"singed (or burned or branded) goose from Canada".
