Avicide. When is a new word appropriate?

["Philip Veerman" <>]

Yes Bob,

 

My comment came about because Bill's message was dual purpose (yes, ambiguous) but mainly about parent birds killing their own young for the purpose of eating them. I took the eating bit as the main question - or was it just killing them. So I wondered why swans were included. After I sent the message I thought this response from you would arise from someone. Yes I was aware that sometimes adult swans harm cygnets and had assumed it was always the young of other pairs (as your story goes), so the reason is territorial and even then I never thought the motive was to eat them.

 

So I stick by my comment in the context it was given but I agree your comments are also true, but that is another issue.

 

Philip

Hi Philip

Regarding Black Swans harming chicks, I have personally witnessed this at Kellies Swamp some years ago.  A new pair of Black Swans attacked the resident pair and evicting them.  At one point I thought they would drown one of them as they sat on the residents back and repeatedly pushing its head under the water,after 5 mins of this mauling the unfortunate swan escaped and flew off  where bye the new pair then chased off the remaining adult.  They then systematically went around the swamp actively seeking the 4 hiding chicks and then thrashing them as a terrier would do a rat. 

I reported this on chat line and one member who had a lot of experience with BS's said "this was more common than one would think"

Hi Bill,

 

I'm a little curious about where it is said that: The male Musk Duck (Biziura lobata) is said to predate its own young. (That is I assume the pun to be using the word "predate" as in eat, rather than occur before, which of course it does............). At a quick look in HANZAB I couldn't find a mention of it in "food", but then where else would they put a bit of text about that? HANZAB does say that fathers are not involved with chicks, they are territorial but do tolerate females with young. Also that the species is odd among ducks that the chicks are closely bonded to mother. So it seems unlikely.

 

Yes Musk Ducks are reported to eat ducklings or young of other species of waterbirds. That is just predation. Male bears will eat young bears that could possibly be their kids but it isn't so common in birds. But could happen, no doubt sometimes does. What is more common in birds that lay too many eggs for all to survive is that the smallest or youngest chick does not get fed or gets bullied by the others and I suspect more often just abandoned or dies and is eaten by or fed to the older chicks (rather than eaten by parents).

 

Why ask the question about Black Swans. It would seem anatomically impossible to me. They don't have a ripping beak and surely would not be able to swallow something that large........ Why would they do that, they aren't even a carnivore?

 

The word Avicide is just "killing of birds" and hardly suits use for the situation of a father eating his kids.

The male Musk Duck (Biziura lobata) is said to predate its own young. What does HANZAB say? What other nestlings / immatures is it known to predate? Fratricide has been used to describe Kookaburra nestlings killing siblings, so when an adult bird kills and eats its own young is that avicide? How common is avicide, e.g. among Australian Magpies and Black Swans? What word best descibes this situation? What other waterbirds may predate the young of all members of the Rallidae?
