Heron Spearfishing



Here we see a Great Blue Heron (Ardea herodias) holding what I think is a Grass Carp (Ctenopharyngodon idella) in a tributary of the Potomac.  Close examination reveals that the heron has not bitten the fish, but rather has apparently speared it.  The heron walked around with the fish like this for a few minutes, presumably waiting for it to die, then dropped it back into the water to eat it.

I have to wonder if there have been any scientific studies of this type of spearfishing by birds.  (I imagine that there have been although I don’t know the scientific literature well enough to say.)  I recall that it was was once proposed, and then dropped, as a potential feeding behavior for certain types of long-jawed pterosaurs (although I can’t find a link for this).

The Absolutely True Story of the Monster in the Wall


Halloween is here again, when I feel that I should post something that suits the tone of the day, even though it is sometimes hard to think of anything.  This year I’ve come up with something that’s a perfect fit for the occasion.

This account is absolutely true, as best I can remember it (and I have a very good memory).  There was documentation for the story, and I have some of the documentation, although I’m not sure where it is at the moment.  The events described did not occur at Halloween, though they do make a good Halloween story.  

For many years I volunteered at a museum.  One service that the museum provided was identifying natural history specimens for the public.  Someone would come across an unusual bone or rock, and bring it in, or otherwise contact us, to get information; the requests were mostly mundane, though sometimes humorous.  

One day the museum received an e-mail from a man in Delaware.  He had grown up in a three hundred year old house.  When he was ten years old, he had found a secret compartment in the wall of his bedroom.  Inside was the body of a tiny monster.  And it was not some toy or model, but the actual carcass of something that had once been alive.

He attached a photograph with his e-mail.  The photograph showed an entity about a foot tall and seemingly bipedal, indeed almost humanoid.  The thing appeared malevolent, even demonic.  And it looked undeniably authentic, even as it corresponded to no animal known on the Earth.  

The man had held onto the monster throughout his life, but he had begun to think that the monster was bringing him bad luck.  Eventually, not knowing what to do, he took it to his bartender. (It is at this point in the story that people tend to laugh.)  Here my memory becomes fuzzy as to what the exact role of the bartender was in these events, but probably he advised the man on how to find out what the monster was, and what to do with it.  

When the e-mail arrived, I had recently been reading about gaffs, hoaxed taxidermy items such as Fiji mermaids and jackalopes.  I suspected that the monster might be some similar fraudulent creation.  I checked the internet, and determined that the monster was a Jenny Haniver, a very specialized hoax item produced when a specimen of the cartilaginous fish known as a ray is extensively altered to appear as some sort of monster.  Jenny Hanivers have been manufactured for hundreds of years; the name is thought to possibly be derived from the ironic French phrase jeune d'Anvers (meaning “youth of Antwerp”, Antwerp being a prominent location where Jenny Hanivers were made and sold). 

This picture from Wikipedia (by M. Violante) is a pretty good approximation of the way that the Jenny Haniver looked, as far as I can remember.



Finding a monster in the walls of a three hundred year old house would make a great premise for a horror story.

Unfortunately, though, I am not a good storyteller.

Some Random Thoughts Involving Music and Biology

The New York state government is battling Giant Hogweed, a conflict of the type chronicled by Genesis in their early Seventies song The Return of the Giant Hogweed.


This news prompted me to do some research and learn that hogweed is a completely different thing than pigweed, which is referenced in a Mark Knopfler song.


The question also came to mind as to why British art rock bands always get biological nomenclature wrong, which is to say that they get it wrong in the two examples of which I am aware. The scientific name of Giant Hogweed is Heracleum mantegazzianum, but Genesis (as I confirmed from the CD booklet) gives it as "HERACLEUM MANTEGAZZIANI". Along similar lines, Yes has a song called The Fish (Schindleria Praematurus), which is apparently named after a real species of fish, whose correct name is actually Schindleria praematura.


The Wikipedia entry informs me that the English name of Schindleria praematura is Schindler's Fish . . . which should not be confused with Schindler's List . . .
