Vampire finches of the Galápagos
by David Catchpoole
Finches are renowned as seed-eaters, able to use their beaks to crack even olive
and cherry seeds. But can finches survive when seed is in short supply?

That’s the situation faced by the sharp-beaked ground finch on tiny Wolf Island,
about 200 km (120 miles) north of the main islands of the Galápagos Archipelago.
For most of the year, this wave-pounded island of steep cliffs and tens of thousands
of seabirds is tinder dry. Any seeds produced in the brief periods of rain are soon
eaten by the finches—leaving them, you might think, facing starvation.
However, film-makers have now documented how the finches turn for sustenance to
the island’s nesting seabirds, in order to survive the extended dry periods.1
For example, opportunistically raiding the seabirds’ eggs. But it seems their
primary source of food during drought is … blood!
some must surely wonder how a God of Love could have possibly made such a bloodthirsty
creature
Despite the seabirds (masked boobies) being much larger, the finches are apparently
able to extract their grisly nourishment from the booby birds with impunity. First,
a finch lands on the tail of a booby. Using its sharp beak, the finch pecks at the
base of the booby’s wing feathers until the skin breaks and the blood begins
to ooze out. Then, every few seconds, it sips the blood. Meanwhile, other finches
wait patiently to partake of this gruesome ‘feeding station’, as the
film-makers observed:
‘Other finches line up behind the booby like a queue at a blood bank and as
soon as one leaves its blood-sucking perch another takes its place.’1
Did God make the ‘vampire finch’?

When many people think of God’s Creation, they think of ‘All things
bright and beautiful … The Lord God made them all.’ But on learning
of the existence of the ‘vampire finch’, and seeing these grisly photographs
(above and left), some must surely wonder how a God of Love could have possibly
made such a bloodthirsty creature.2
The answer, of course, is that God did not make the finches to live in such a manner—originally, all animals/birds were vegetarian (Genesis 1:30). But after Adam sinned, death and bloodshed
entered the world. The Galápagos finches give us an insight into how some
instances of carnivory may have arisen after the Fall, and also after the Flood.3
The first finches4 to arrive in the Galápagos Archipelago5 (probably from
the Americas, as Charles Darwin surmised) were likely to have still been seed-eaters.
But on islands where there was a shortage of seeds, some finches learned to use
their beaks for other purposes, e.g. probing under bark for grubs.6 And on Wolf
Island, the sharp-beaked ground finch discovered its sharp beak was useful for procuring
itself a nutritious though gruesome ‘liquid lunch’.

- God did not create the various finch species in the Galápagos
Islands during Creation Week, as some people (mainly long-age compromisers) have
erroneously suggested in the past. (a) The world’s pre-Flood geography would
have been radically different from today’s post-Flood topography. (b) Today’s
‘species’ (an artificial human construct) are descended from the original
biblical ‘kinds’. The speciation evident in the finches and other creatures
that have migrated to the Galápagos since the Flood is not evidence
of evolution—see Wieland, C., Darwin’s Eden, Creation 27(3):10–15,
