All kinds of things can trigger deep thoughts in me, many of
these thoughts are often nonsensical and sometimes not suitable for broadcast
but quite often a chance observation will lead me down a rabbit hole into areas
I never considered before, one such event occurred this past week.

He seemed incredibly proud of his feather. He stood boldly
on the fence waving it around and repositioning it in his beak to gain maximum
purchase in the light breeze. He was pleased to have found himself such a premium
piece of nesting material, I was surprised then when his behaviour suddenly
changed. As he looked around him, no doubt looking to display his find to
receptive females and brag to the other males his gaze alighted on the bird
feeder. Instantly his demeanour changed, he dropped the feather and fluttered
down to one of the perches. He stuck his head in and took a few beak fulls of
seed before flying off. He did not look for his lost feather or even show any
awareness that he had even had one in the first place. It was if seeing the
food overrode his previous behaviour and excised it from his awareness.
So, what then was going through the sparrow’s mind. It led
to me to think about the depth of intelligence such an animal might have. Was
the sparrow just a flesh and blood automaton operating purely on an innate system
of stimulus and response pathways, on the larger scale is that all that we
humans are? Had I seen evidence of two competing innate systems going head-to-head
in a priority led battle for survival?
The sparrow, I reasoned, had received the signals of day length
and temperature, and responded biologically with hormonal changes to begin the
mating sequence. Mating is a strong imperative in all species and particularly
in humans can lead to levels of extreme stupidity. The sparrow had started nest
collecting behaviour, the collection of the feather was evidence of this, and
he had done well. The feather was A grade nesting material, with excellent thermal
properties and incredibly soft, Mrs Sparrow would be impressed. However, had
the sight of food initiated a different neural pathway that prioritised
survival over reproduction, you cannot after all, reproduce if you have starved
to death!

During my undergraduate dissertation I studied optimal
foraging theory in woodland birds and whilst the outcome of my studies were embarrassingly
naive it did leave me with some insight into the complex cost benefit analysis
birds undertook to balance energy gain and energy use on a daily, even on a minute-to-minute
basis. What then of choice and intelligence? Was a measure or mark of intelligence
the ability to choose to override an innate response. Was this what humans did?
Was this ability, this flexibility, a competitive advantage that allowed other organisms
to survive in new and exciting ways?
Ironically, the New Scientist has just run an article on
animal intelligence, I had just finished reading Peter Godfrey-Smith’s excellent
book, Other minds: The Octopus and the Evolution of Intelligent Life and Chris
Packham’s BBC series on Animal Einstein’s had just finished airing, something
that perhaps helped channel my thoughts and highlighted the difficulty of
assessing intelligence even in human species let alone between those of different
genera, families, or classes.
Alongside raw problem solving these is a question of culture
and continual mental block humans place on research, always placing ourselves
at the top of the tree or at the centre of any level of supremacy. We are the benchmark
upon which all else is measured but given the breadth of life is this true? We
count ourselves at the pinnacle and yet our species is very new and short lived
one in geological speaking. Bacteria have been surviving relatively unchanged for
hundreds of millennia, they are more diverse than mammals and able to survive
over a broader range of environments. It is our own perceptions that can
blinker is to what the sparrow is thinking. Are the sparrows through processes
nothing more than a sequence of NOT, AND, and OR gates and if so, are our own
thought processes any different all be it more complex and confounded by self-identity
and self-absorption.
One only needs to lock eyes with an animal to experience a
kinship, some level of understanding, something that changes as we move through
the species. I have never ‘had a moment’ when staring into a Bees eyes. A mammal’s
core experiences are not that dissimilar to ours after all once you distil it
down. Birds however are a step removed, their 3D awareness from flight and different
perceptual mechanisms perhaps removes them more from our frame of reference.
After all, when caring for injured birds I have had such moments of connections
although this could just have been projection on my part.
At the end of the day, we cannot be sure what our nearest and
dearest are thinking so why expect to be able to do so for another taxon. Is
this pursuit of understanding futile? Maybe, but it is a fascinating journey,
nevertheless.
