Help needed. PERPETUATING the great BUTCHERBIRD MYTH
In a reply to JAG, copied below, Philip Veerman
inadvertently assists in perpetuating what I regard as one of the
greatest myths in Australian ornithology.
That Butcherbirds impale their
prey.
At least I have found no evidence of this in
Grey Butcherbird which I have observed in detail over many years. To the
contrary, even when storing food in their 'larder' as it has been called, in
trees with numerous spikes or thorns, they choose not to impale, instead
wedging it between the spikes or in clefts, never securing it on a spike as
do the Lanius Shrikes.
Convinced of the above, the late and great
Graham Pizzey raised the matter with me and we exchanged some
correspondence. I like to think that partly as a consequence of that
exchange, on page 542 of the Pizzey & Knight Field Guide he wrote the
following.
"Larger victims are wedged into a fork (or
an angle in wires of a fence or clothes-hoist) for purchase to tear against.
But prey is seldom if ever impaled on
thorns".

This seems like a typical thing for
a butcherbird. There is nothing new or astounding about it. More to
the point, other things don't do this. That is where the name comes
from, hanging meat on hooks, like a butcher. The shrikes of northern
hemisphere do the same. The thing is, they don't have strong feet
like hawks have, so they need to secure prey on something, while
they tear it up.
