The Rockface pigeons under discussion, have happily shed the tag of “living in pigeonholes” and the centuries old word 'pigeonhole’. The high-rise buildings offering rent free spaces, why would they settle for less? With them focused on a mission in life to survive and proliferate, it becomes next to impossible to evict these two-legged squatters.
Reluctant to go outdoors, I decided to study the roosting pigeons by adopting
this observation-questions -published information technique - a Q&A with
self-study. I chose three all-weather observation posts, with guaranteed
visibility, that are within a few steps of each other for this purpose. The
O.P1 is on the sunshade, below an outdoor ac unit of the opposite apartment, with
a view from my bedroom window. The O.P2 is on a similar sunshade of the same apartment,
just in front of my standing room only balcony, though sighting is
through defensive nylon net backed by a grill work intended to keep away
pigeons. The O.P 3 is on a sunshade of a neighbour’s apartment, with an anytime
view from the common corridor.
The male pigeon struts around
and waddles on the sunshade moving its body from left to right, bobbing its
head back and forth as if practicing its own brand of ramp walk. On the other
hand, the female, smaller in size, appears calm, unhurried and cautiously moves
around. Sometimes, for the fun of it, both keep tracing imaginary circles, without
their bodies touching each other like the spools rotating in a tape deck. To impress the female, the male flutters its
wings and puts up an impressive airshow with take offs and landings.
Physical attraction having been established,
the pigeons start working on the body chemistry and then move on to biology
classes. Intuitively knowing the purpose of their life, the pair selects a location to build a nest with
slender reeds, sticks from broom, fibrous material or simply use any depression
on the surface of a sunshade. Their objective is to have a nest with protection
from the elements and a safety net for the eggs from rolling off the ledge. The
roosting pair has to remain alert to danger from the cheeky squirrels. These
fury-tailed villains think that the unguarded eggs, or squabs are fair game,
for fun or pizza.
I gave up identifying one pair
of pigeon from one another as it was like saying this and particle is different
from that sand particle. The pairs of pigeons come home to roost at the same location,
driven by the motto - Familiarity
breeds squabs.
The twin mysteries, why they choose to rest - perched precariously on
drainpipes, edges of sunshades, and other uncomfortable niches and in this position
how do they manage to sleep without falling over? The pigeons must have gone scientific by adopting
a unihemispheric sleeping technique, where one-half of the brain is
resting the other half stays awake & alert to threats and falling off from
the perches.
To be on the safer side, I confirmed with the published materials that
my observations cum conclusions on gender identification, distinguishing pairs and
their courting rituals are more or less correct.
The story from O.P 1:
A pair of pigeons made several flybys to select the sunshade under the outdoor ac unit. Their logic must have been to make use of some of the machine generated heat for use in hatching the eggs. Since this Observation Post was not under my constant surveillance during courtship and the delivery of eggs remained like an unread chapter to me. Returning home after a few days of absence, I noticed a solitary egg, carefully set amidst some trash material. One of the pigeons was maintaining the line of sight while the other kept the egg warm.
Given little more time, I would have
understood that the pair shared the duties in the nest. The single egg was a pointer
towards two possibilities. The female is yet to fully mature and build up
stamina or has past its prime with depleted strength. Due to my inexperience, I
had missed the important physiological indicators like colour of feathers or
other physical characteristics.
Left to its own devices, when the parents were away from time to time,
the egg had started to change position every day till the shell started
developing hairline cracks. Finally, when the shell broke into two halves, I was
able to view the dark lump of a squab. An ominous development occurred when a
squirrel emitting squeaks had decided to investigate the site for its own nest,
on the wall mounting bracket behind the outdoor unit.
By this time, the pigeons thinking that they have done all they could
do, started to keep irregular visiting hours. Unaware of this lurking danger,
the squab in the eggshell continued to shift around. The squab residing in the
broken shell must have presented a tempting opportunity. Emboldened, the
squirrel seized control of the situation. Belting out loud ‘squeaks’, it
scurried down on to the sunshade a few times, to assess and plan its move but
tactfully withdrew sensing my presence.
Next morning, alerted by the unusual noise, I hurried to the window. The
agitated pigeons were flying over the spot where the squab should have been. The loss of the squab must have formed an
emotional storm and waves of distress in their tiny brains. They could do
nothing but aimlessly walk on the sunshade and emit repetitive moans, which
sounded tragic & forlorn. The grief-stricken pigeons were trying to
understand what had gone wrong, probably thinking that their agitated pacing
would bring back the squab well and alive.
Oddly, the metallic sounding squeaks and the squirrel have gone silent. I
could only guess that either the squirrel has pushed out the squab in the
broken shell, to prevent the pigeons from disturbing its nest or might have
feasted on a free meal. A heart
wrenching sight for any human observer. I watched them for some time lost in
thoughts as to what could I do to console them.
The story from O.P 2:
The neighbours did not pay heed to my concern about the health issues
attributed to these squatters. Unable to sleep under the unrelenting heat wave,
I migrated to my stamp sized balcony to appeal to the clouds to stop debating
and start raining. Undisturbed by my presence, pairs of pigeons clung to drainpipes, wall mounted brackets, exhaust fan frames, windowsills and sunshades as
their sleeping quarters.
Next day morning, I noticed a pair of pigeons busily engaged in spreading sticks of a broom, on the sunshade opposite to my apartment. Correcting my earlier mistake, I easily identified the male pigeon by its body build, strutting, loud coos and puffed out neck and chest feathers. To actively court the partner, he attempted to dazzle the female with bright iridescent feathers on his neck.
The
sleek female pigeon, with not so iridescent neck feathers, participated
enthusiastically. At times she refused to play along by crouching down flat on
the sunshade to discourage further entreaties. After some more cooing and
ring-a- ring-a- roses dancing, the female pigeon playfully attempted to adhere
to the wall.
Piqued by this act, I stood
rooted to my spot, recollecting the published facts that being monogamous
and in their prime, the pigeons continue with the courtship which triggered
the ovulation cycle in the female pigeon, signaling her readiness to start a
family.
After a few reruns of this episode, the pigeon playfully attempted to adhere
to the wall, delivered an egg after a few days and by pure chance I happened to
witness the egg being delivered, in real time. Then, using her beak and legs she
started to nudge the egg around to keep it safe behind the barricade of
arranged broom sticks.
I geared myself to clock the arrival of the second egg and chronicle the
hatching event. Unaware of this developing situation, a squirrel was sprinting
up and down, along a vertical drainpipe with whatever mission it had in its
mind. I called it a day after verifying that the second egg has not been laid
yet.
The next morning, the vacant space told me the sad story. The egg and the sticks of the broom have been swept off the sunshade. The clueless pigeons, vainly searched for the missing egg and the sticks of the broom. Tragedy notwithstanding, the female pigeon was on a clock to lay the second egg within 48 hours, before it gets air dropped. Their plan to hatch a male and female squab at that place going terribly wrong, the heartbroken parents might have departed in search of another location.
Who stole
the egg and removed the sticks of the broom? Whether the second egg was laid in
time, in another place? Mysteries fit to be solved by Sherlock Holmes! Needless
to say, I closed my observations with a heavy heart.
The story from O.P 3:
This neighbour had refused to clear the debris and fill the shallow pit
on his sunshade. I had even pointed out the pair of pigeons eyeing the shallow
depression and debris for a possible hatching site. For good measure I reminded
him that that a pair of pigeon or the bulbuls chose the same place again,
perhaps for sentimental reasons after having completed a successful batch. I
drew his attention to the bird droppings already on the sunshade to drive home
my point.
After a few days, my apprehension became a certainty. The female pigeon
was calmly doing sentry duty guarding two eggs. The debris, the depression and pigeon
droppings had become home for the eggs.
Whether the pigeons counted the days or not, I did. In the interim, I
learnt that a mature female pigeon is a fast breeder reactor, brooking no delay
or disruption in her egg laying cycles. She can initiate her ovulation cycle at
will. Typically, she delay-starts the hatching process by 2 days, to match with
the arrival of the second egg.
Within 4-6 weeks and at times even when the hatched squabs are
still in the nest, she is ready to lay the next clutch of eggs. I
started to wonder whether the pigeons are targeting to achieve the maximum
number of hatchings like the possible number of New Moons or Full moons in a
calendar year!
With such energy consuming activities ahead, the parents share the workload
in nest keeping duties. The female stays with the eggs/squabs from late
afternoon till about mid-morning and the male takes over for the midmorning to
the late afternoon shift. This shift rotation allows the female pigeon to
recuperate and refresh.
On the fag end of the 3rd week, the broken shells announced
the increase in the population of pigeons, with at least one female squab. A
squab of Rock face pigeon starts as an indistinguishable lump, with pale yellow or yellowish gray coloured
feather, at birth. As it matures the colour gradually changes to gray.
The squabs must be feeling lucky as both the parents take turn to feed
them with specially secreted crop milk. As the squabs age, the frequency of
parental visits becomes sporadic as the squabs have been fed with enough
nourishment. The parents have done their
best. The infrequent visits and hunger make the squabs to leave the nest early.
The absence of the marauding squirrel remained a puzzle, but it had helped the
eggs to survive, avoiding a heartache to the parents.
After building up sufficient strength to survive on their own, the
fledglings fly away, probably vacating the space for their parents to start the
next batch, though I am yet to confirm this. In the world of pigeons everything
has to run like the parts of a Swiss clock.
The squabs mature in about eight months. But within 4-7 months,
the yet to fully mature female pigeon might start laying one egg per clutch
signaling the arrival of another fast breeder reactor. Older or under
nourished female pigeons adopt this one egg per clutch rule to ensure survival
of the hatched squab.
No doubt, the pigeons proliferate and use our premises as their
washroom facilities. The stink arising from their droppings and fallen feathers
ranks alongside the foul smell that assails travellers as the train approaches the
outskirts of a typical metropolitan city.
Setting aside my deep-rooted
pathological aversion to the pigeons to take a
closer look at their life cycle was
immensely rewarding. It forced me to learn
published materials, become a Zoolinguist and an avianliguist to
understand their feelings on my way to become an indoor ornithologist!
