The Crying Seagull
The crying seagull, Larus
fleo, has been considered an
incarnation of the gods by the people of the Kalahari desert since
ancient times. With a wingspan of up to one meter (~3.28 feet), the
crying seagull is one of the larger members of the Laridae family,
and flocks of the pure white birds are an impressive sight to behold.
The birds always preceded the rare rainfalls in the Kalahari, which
is why the natives gave them their name.
The
exact reason why the birds would precede the rain, and not follow it,
has so far eluded scientists. This peculiar behavior means that the
crying seagulls arrive in the Kalahari when it is at its driest, and
food and water are scarce. Early hypotheses about the behavior
thought the gulls might feed on the animals that had succumbed to the
harsh conditions, but observations on the field have yet to record a
single instance of this behavior.
John
de Galle, of the Paris Institute for the Study of Creatures With
Feathers (PISCWF), who has recently been nominated for the French
Award for Having Studied Stuff (FAHSS) for his paper on the
behavioral patterns of the Paris fashion week, has stipulated that
the birds use the strong winds that precede the clouds to migrate
over the African continent, a journey which, according to Dr. de Galle, they could not undertake
under normal conditions.
Recent
observations of the climatic changes that are starting to affect the
Kalahari desert have shown that the population of crying seagulls is
directly dependent on the amount of rainfall in the desert. The
fluctuations of both the gull population and annual rainfall are in
perfect harmony. Although most scientists agree that it is the
fluctuating climate that influences the birds' population, some have another explanation.
“Normally,
when a population declines in reaction to a change in the
environment, there is a lag period between the environmental change
and the population change. This is not the case here, since the rise
and fall happen at exactly the same time. The only explanation is
that the two changes share the same cause”, said Thomas Fifi, of
the African Institute for the Study of Dry Places (AISDP).
