Birds @IIHMR University 4: Ruminations on gliding equilibrium of House Swifts

In the housing block of IIHMR University, Jaipur the gliding flock of House Swifts hovering over terraces is sure to catch anyone’s eye if one has a predilection for sky gazing in daytime. The House Swift is a tiny bird (around 15 cm). They are stocky shaped with comparatively short wings and are gregarious creatures, like to playfully hover around in flocks.

Flapping their wings and gliding, allowing to be guided by the flow of wind, they form different configurations that conjures up images of a harmonious dance ensemble like that of the swirling Betkashi Sufis who passed this trance inducing dance to the more well- known Mevlevi order of Maulana Rumi, the great sufi saint of Konya, Turkey. Being bewitched by their entrancing movements, rushing to the terrace for catching their glimpse in morning and evenings became a pleasingly compulsive attraction. Courtesy the play of sunlight, each of these times of the day revealed different shades and silhouettes of these deft and agile movers. The white patch at the bottom of their face or lower rump of their body or their slightly forked tail would shine and be visible for a split second in the bright and sunny summer mornings. They were conspicuously absent in afternoons. Maybe the bright sunlight and heat was a deterrent.   Although the fading light of evenings was not illumining enough yet the outlines of fast moving Swifts created dynamic patterns that were alluring enough to keep you spellbound for some time. On breezy days this orchestration becomes a vivacious display animating the sky above you. Their movement assumes a resplendent motion wherein they come and go away from your sight horizon with a rapidity that is free flowing yet under supreme control. On these windy days their elation knows no bounds and you could actually hear their sweet chirping resounding in sky they traverse. In contrast to this, days when there is no wind their gliding continues for that is their natural motion but is perceptibly sluggish only sustained with the help of almost continuous flapping of their small wings.

Some days of this patient gazing at their sharp movements revealed the utter limitations of human eye in catching heir swift movements fully and as a result their full body remained an elusive mystery. Indeed it has been carefully observed by ornithologists and bird enthusiasts that Swifts are capable of sleeping while flying. They spend their life almost entirely on the wing and can mate, as well as eat and feed in flight. Such is the speed and supreme balance these avian beings have been gifted with[1].

Closer observation, that was only possible using binoculars, of this rapidly moving retinue of tiny winged beings makes you discern a distinct pattern- usually two Swifts would be forming a pair and many such pairs would animate a circumscribed area in sky where they would circulate freely. The movements usually consisted of synchronic gliding in pairs and then individual Swifts darting off with rapid speed into lower heights and again rising high coming together in pairs to repeat the cyclical round of the circumscribed territory. Interestingly each time the movement would be different from the loop each of the pairs had accomplished earlier. And this playful synchronic movement of gliding equilibrium would continue with vim and vigor.  

The effortless floating of these Swift pairs together making a collective of more than twenty thirty is compelling enough to invite ruminations about humans and nature. Their myriad configurations could be understood as heterarchies. Heterarchy may be defined as the relation of elements to one another when they are unranked or when they possess the potential for being ranked in a number of different ways[2]. These formations where each element possesses the ability to be ranked in a number of different ways are suggestive of the phenomenon of ‘continual re ranking’.  They provide a refreshing contrast to bland and rather reductionist notions of hierarchies that have “….disproportionately influenced understanding of complex behavior in social, ecological and scientific contexts...”.Indeed this understanding of heterarchies lies at the core of understanding ‘talking of neurons’ and in unlocking the mysteries of ‘tell- tale brain’ and has contributed significantly to advances in Artificial Intelligence. 

The gliding equilibrium of the not so easily visible flock of Swifts and their strange loops of numerous  configurations innocently remind you of tangled hierarchies, wherein each one has the potential and ability to be on the top. It is a soulful reminder of the deeper metaphysical truth that being on top itself is impermanent, toppled as it is by another pair that glides above the erstwhile topper and so on and so forth.
