I never get bored watching the antics of these vibrant golden yellow birds with black eyestripe that resembles the eye makeup of a woman with kohl eye cosmetic and their alluring black bordered wings. They are named as Orioles ..We can see them forage in trees and hear them sing melodiously echoing through the stillness of the woods.
Their territorial face-off and chases enthuse me. Ripe papayas attracts them to the garden. It’s interesting to see how they clamp on to those fruits carving out the sweet flesh and gorge them with their slender pink beaks.
I just couldn’t resist myself from posting these pictures of one of the loveliest marvels of nature. Two of them I clicked with my camera and the other one I painted.
All days are not the same. Sometimes we feel energized to take up any challenges, other times we tend to lose hope, drained and devoid of insight. That’s what I felt one day and I kept procrastinating things. Aimless. Wasn’t able to figure out how to start with and what to??
I saw a tailor bird out amongst the undergrowth chirping and springing from one leaf to another, one twig to another briskly. We share no commonality, I began to ponder, analyse.
She/he did have an objective. May be it was food or nest building or something else but definitely it was preoccupied with the purpose that nobody decreed upon it.
I felt motivated to start my day from somewhere in whatever little way I can, without bothering much about the perfection and without being judgemental about myself.
My painting here is the outcome of my appreciation for you little bird.
One morning, as I was at my desk,
I happened to catch sight of two sunbirds taking turns feeding a larger sized
bird, perched on the branches of a semi evergreen forest outside my window. The
sunbirds looked exhausted feeding insects to the big one. I got intrigued by what I saw, for I had
little knowledge of the mystery that’s unfolding before my eyes. Why would
sunbirds as small as 10 cm in length feed a bird that is heterospecific and
larger about a length of 15-16 cm? I sensed that this moment shall pass away in
no time; I grabbed a white paper and started sketching outline of what I was seeing.
Their interaction as I anticipated didn’t last for long, the trio had translocated.
hell bent on finding the reason behind this subjugation. I went ahead recording
in my nature journal the details such as
date of observation: 10/02/2013
temperature outside: cool at 25 degrees
in Middle Andaman islands
Name of the sunbirds: Olive backed sunbird (Cinnyris
jugularis Andamanicus)(Linnaeus,1766,Syst. Nat.ed), identified with the help of
the book. The underparts of both male and female are bright yellow; the backs are
olive green in colour. The forehead, throat and upper breast of the adult male
is a dark, metallic blue-black. They have slender decurved bills and feeds on nectar
as well as small insects
Name of the larger bird: juvenile of Violet cuckoo
(Chrysococcyx xanthorhyncus,Horsefield,1821), Violet
Cuckoo is distributed throughout south east Asia and Indian subcontinent (Ali
and Ripley 1981; Rasmussen and Anderton2012). The violet cuckoo species are
partially migratory birds.The breeding cuckoo populations in northeast India
(Assam, Meghalaya, Nagaland, Manipur, Mizoram and Andaman and Nicobar Islands),
Bhutan and Bangladesh are migratory and they move southwards for wintering.
Juveniles have barred rufous and greenish bronze feathers on the upper parts of
the body, a bright rufous crown, rufous and mottled green or brown wings, a
barred brown and rufous tail and brown-barred white under parts.( “Chrysococcyx
xanthorhynchus”. BirdForum. Retrieved 4 February 2014.)
When I searched for the details on why is a
sunbird feeding a cuckoo baby? ,there were lots of literature and research done
on cuckoo as harbinger of spring and as “brood parasite”, the behaviour of
relegating incubation and rearing of offspring to other “foster parent” birds
and that Olive backed sunbird is known to be parasitized by cuckoos(Cheke and
In the book The Avian Brood
Parasites: Deception at the nest by Paul A Johngard, the author has referred to
the adaptations of obligate brood parasites like common cuckoo to ensure continuity of their species.In
obligate brood parasitism the female cuckoos regularly deposit eggs in other
species’nests, but do not perform any nest building, incubation or parental
behaviour. Parasite benefits but host suffers from their breeding interactions.
that brood parasitism is more common in the cuckoos because they may have been
able to “let go”their rather weak nest- building tendencies more easily than
passerine groups which have strong nest building instincts and complex nests
such as weavers and icterines.
Some of the publications
elucidate the various tactics and circumstances that make a cuckoo species
successful in parasitizing their host’s nests. I noted down some of them as
Female cuckoos have secretive and fast laying behaviours, but in some cases, males have been shown to lure host adults away from their nests so that the female can lay her egg in the nest.(Davies, N.B.(18 April 2011)”Cuckoo adaptations: trickery and tuning.”Journal of Zoology .284 1-14 (doi:10.1111/j.1469-798.2011.00810)
The parasite’s eggs are somewhat larger and rounded and harder for host species to pick up(Hoy and Ottow,1964)
Incubation period among cuckoos are unusually short compared to other families of bird(Lack, 1968), so the chances of predation of their eggs get reduced.
Cuckoo lays eggs with thick shells that provides resistance to cracking when the eggs are dropped in the host nest.(Antonov, Anton;Stokke,Bard G;Moksnes,Arne;Roeskaft,Eivin(2008)”Does the cuckoo benefit from laying unusually strong egg?”Animal Behaviour.76(6):1893-900. doi:10.1016/j.anbehav.2008.08.016.)
The cuckoo egg hatches earlier than the host’s, and the cuckoo chick grows faster.
The cuckoo’s chick evicts the eggs or young of the host.It has been suggested that ejection behaviour probably occurs in Asian and African emerald cuckoos and violet cuckoo, but observations are lacking(Friedmann, 1968). Disposal of potential competitors in the nest via nest ejection by common cuckoo was first described by Edward Jenner(1788). The chick has no time to learn this behaviour, so it must be an instinct passed on genetically. The chick encourages the host to keep pace with its high growth rate with its rapid begging call.(Adams, Stephen(2009-01-04). “Cuckoo chicks dupe foster parents from the moment they hatch”.(The Daily Telegraph, London. Retrieved 2010-04-30.”Cuckoo chicks start to mimic the cries that their foster parents’ young make from the moment they hatch, a scientist has proved.” The chick’s open mouth which serves as a sign stimulus.(Biology(4th edition)NA Campbell, ‘Fixed Action Patterns’(Benjamin Cummings NY, 1996) ISBNO-8053-1957-3
Wyllie(1981) described ejection as follows “From about 8-36 hours after hatching, the young cuckoo wriggles about in the bottom of the nest until it manoeuvres one of the host’s eggs against the side of the nest. Its back has a slight hollow between the scapulars which traps an egg against the nest wall. The cuckoo’s head is held down, almost touching its belly. Then with its feet apart and with muscular thighs the youngster slowly works the egg up the side of the nest, holding its tiny wings backward to prevent the eggs from rolling off. When it nears the nest rim the wings clasp the top as the legs push up from the side of the nest. Balancing the egg on its back to the top of the nest, the young cuckoo quivers and jerks for a few seconds and hangs there feeling with its wings to make sure the egg has gone over. Then it drops back into the nest cup. “This process is repeated until the nest is empty of other eggs or chicks.
It was disturbing to see this video but it says it all:-
After examining the above reliable sources dual feelings crept
into my mind as to whether I must feel happy seeing the parenting instincts of
olive backed sunbirds towards caring for a much larger bird, or to empathize
with the couple who were forced to grow up a species who may have been
responsible for making them loose their own progeny.
What might have happened to their actual offspring?
They may have met with the same fate as in the above video. I had begun to understand the reason why those sunbirds were compelled to feed the cuckoo offspring. That was disheartening to know that the two smaller birds were deceived and victimized, having said that , I think they have enabled us to gain knowledge of a kind of co evolutionary interaction named brood parasitism and made us ponder about the cost of parental care among birds.

poster colours and set aside as one of my treasured encounters with bird

OLIVE-BACKED SUNBIRD CINNYRIS JUGULARIS NESTING
FROM ELECTRIC WIRES IN GREAT NICOBAR ISLAND, S Pande, N Sant – indianbirds.in
I cherish the memories watching from my balcony a flock of elegant brown backed needle tail birds hovering over grassy vegetation backdropped by Panchwati Hills, Middle Andaman. The weather had been cool from November to February and that’s when these birds are sighted the most. They are brown backed except for the white under tail seen flying swiftly and constantly for hours with their sickle shaped wings and spiny tail ends . I have not seen them settle down anywhere within my field of vision , they would have probably got back to their nests by dusk.
I miss the alluring beauty of nature and the tranquility of the moment that embodied them. Fortunately I captured them in my illustration using poster colors.
I was woken up in the morning by the whistles and chuckles of birds that were not visible to me in the first instance. On scrutiny of my backyard forest, I got a glimpse of a flock of brown backed birds with black ‘necklaces’. They were scurrying through the thick undergrowth. Though I maintained my gaze into the sparsely lighted forest with leaves of different shades of green crisscrossed with trunks and offshoots of varying thickness I couldn’t identify them. Before I could do so they took wings afar and vanished.
By late morning I happened to spot one of them alighted for a siesta on a branch . With more details of the bird, such as white supercilium above the eyes, black eye ring …. coming into light, I was able to recognize the bird then and take snaps. My reference book for birds suggested the name Lesser Necklaced laughing thrush. ‘Laughing’? In retrospect, I recalled the cacophony of chuckling sounds I heard previously. Subsequently, I drew the bird on a paper with oil pastel.
I saw the cover page picture of the book Birds of the Indian Subcontinent by Richard Grimmet, Carol Inskipp, Tim Inskipp and got impressed by the art work by John Cox. I tried doing a pencil sketch of Coppersmith Barbet a frugivorous bird found in wooded areas. I know that the quality of the picture is nowhere near that of the original picture or the magnificient beauty of the bird in real.
I took to color pencil drawing as I noticed its de- stressing powers and as an ideal way to break the monotony of my routine works.
We can see rock pigeons in villages and towns comfortable with human presence, feeding on insects and grains. Their grey body with black bars across wings, green and pink iridescence on neck are alluring. They feed usually in flocks and roost on roof tops or window shades. It’s entertaining to watch them bobbing heads, preening feathers and gathering twigs during nesting season. Their deep cutrr-coo calls and sounds of their flapping wings are one amid varied sounds that urban dwellers hear all day except that birds sounds are calming to our senses.
An Alexandrine parakeet perched on the highest point of a deciduous tree after it foraged on wild fruits a short while ago. The enchanting beauty of the parakeet enticed me to try emulating it on a paper.
It’s comparatively large with red beaks, red patch on wings, green feathers,pink collar,black chin stripe,long green tail with blue in the middle and yellow tips against the backdrop of a vast blue sky.
