Brahminy Kite: Nesting observations

aaa32.jpg

In March 2007, Mark Chua came across a nesting pair of Brahminy Kites (Haliastur indus) (above) raising two large chicks in a nest lodged high up in the fork of a tall casuarina tree (Casuarina equisetifolia). He managed to document the chicks in the nest, their fledging as well as many dramatic flight shots.

Like most other raptors, the nest is a large, untidy pile of sticks (left). According to Naoroji (2006), the nest is usually lined with common discarded items like rags, strings, pieces of plastic, etc. However, this cannot be confirmed here as the images failed to show other than twigs. It is also reported that the birds build a new nest each season, sometimes recycling the old nest materials, at times even reusing the old nest after some repairs.

Wells (1999) states that the inner cup of the 60-90 cm diameter and 15-30 cm deep nest is lined with a pan of dried mud, 10-15 cm across.

Two or even three eggs are normally laid and both sexes share in the incubation duties. In this instance two chicks were raised (left bottom).

As reported by Wells (1999), food is often eaten directly while soaring.

This large kite has a striking plumage of rufous-brown and white as an adult. The head, neck to mantle, and throat to upper belly and flanks are all white. In the nominate subspecies, indus, that is seen in the Indomalayan region, the white has finely darkish streaks (top).

From below in flight, the white head, neck and breast contrast sharply with the chestnut lower belly, deep chestnut underwing-coverts with pale chestnut-buff under flight feathers with contrasting blackish primary fingers.

The juvenile is mostly brown, and this has been reported to vary with the season. From below the white-tipped underwing-coverts and large white wing panels are prominent.

Tanimbar Corella: A wasteful eater?

aaa23.jpg

On the evening of the 23rd July 2007, at about 6.00 pm, I heard a sharp cry of the Tanimbar Corella (Cacatua goffini) coming from the starfruit tree (Averrhoa carambola). The bird is usually shy and will fly off as soon as it sees me. But this time I was behind the glass window of my bathroom about slightly more than a metre away and could observe at close hand. It did eye me on and off but by not moving my head it was not bothered by my presence. It continued picking on the fruits.

The lone bird was perching on the branch. It reached out to a young, green fruit with its bill and expertly plucked it from the short stalk (above left). Then, with the right foot gripping the branch, its left foot moved up to take hold of the fruit. With its sharp pointed bill, it bit off bits and pieces of the fruit along the flange and dropped them below. Then it dipped its bill into the core of the fruit and extracted the seeds inside (above right).

One by one it plucked the green fruits from its perch, ate the seeds and dropped the remaining fruit below (right). When it finished with the fruits around, it walked along the branch to another spot and did the same. All the time it was eating, it gave out a harsh, monosyllable sound.

For some time now, I have been under the impression that the bird is a wasteful eater, eating pieces and then dumping the rest of the fruit. Obviously I was wrong.

Sleeping Chestnut-naped Forktail

Since the posting of Sleeping Birds earlier on, a few people have written expressing concern about disturbing these birds in their sleep, especially when flash is used to photograph them.

chestnut-napedforktail-for.jpg

Forest Ang is one such concerned person. He was at Maliau Basin, Sabah when he came across a sleeping bird when out frogging along a small stream one night (left). The sleeping bird had its head buried under its wing.

“I took this sleeping Chestnut-naped Forktail (Enicurus ruficapillus) on a branch over a running stream. It was curled into a ball. I saw several mosquitoes on its toes. I think it got a fright when it suddenly woke up to see a shining torchlight. It flew aimlessly like a drunken bird.

“I really felt sorry for the intrusion. Perhaps we photographers should restrain ourselves from getting too near. It could hit a tree and injure itself in the darkness.

“I had a few previous encounters with sleeping birds but all of them were not bothered with my presence.

“After the Chestnut-naped Forktail, I have been restraining myself from the urge to take pictures of sleeping birds…should we? What is your comment?”

See Forest Ang’s video here!

Yes, flashing sleeping birds may disturb them. As I earlier posted in reply to Serene, some birds may actually be disturbed, waking up for a moment, to go back to sleep. Others may be oblivious to the flashes and continue sleeping…

Personally, I think there is nothing wrong with taking photographs of sleeping birds, as long as we do not overdo it. It is the same with photographing nesting birds. How else do we add to our knowledge of bird behaviour? We do need such documentation. Taking photographs is a lesser “evil” than taking specimens of animals for study.

As long as we do things in moderation, we would not be disturbing the birds too much. It is only when a few photographers descend on the scene, each releasing a dozen or so flashes at the sleeping or even a nesting bird, that we are causing problems.

Golden-bellied Gerygone and Little Bronze Cuckoo chick

1115-11-35-49.jpg

A pair of adult Golden-bellied Gerygone (Gerygone sulphurea) were spotted frantically feeding the chick of the Little Bronze Cuckoo (Chrysococcyx minutillus) in fig tree in a park in early August 2007. The adult gerygone is a smallish bird about 10 cm long while the cuckoo is 16 cm long. Or that is what the guidebooks say. However, the images captured of the feeding pair show the cuckoo chick to be nearly twice as large as the gerygone adult (left and below left).

The gerygone, being small, can only catch small insects. The chick, being large, was not easily satisfied by the number of small insects fed to it. The result? The foster parents had to work frantically like feeding machines to appease the hungry and noisy chick. And this went on for days on end.

And there was an adult cuckoo in the vicinity. Was it keeping an eye on its chick? To ensure that the foster parents were taking good care of its biological chick? Food for thought eh?

There was only one cuckoo chick (above right). I suppose the small nest of the gerygone cannot handle more than one large chick. And to be left with two large cuckoo chicks to feed will be too much for the adopted parents.

The Little Bronze Cuckoo is a brood parasite, laying its egg in the nest of the Golden-bellied Gerygone. Once the cuckoo’s egg hatches, the chick will eject the eggs of the host.

Go, going, gone - My habitat

The founding of Penang Island in the late 18th Century by Sir Francis Light marked the beginning of 171 years of British rule in Malaya.

Province Wellesley on the mainland, named after Lord Wellesley, has always been made to feel and treated somewhat like a step-sister to the island state.

Geographically, it is something like Kowloon and Hong Kong Island. Except that in Province Wellesley, there aren’t any nine hills to boast of any good Feng Shui - Chinese art of divine intervention to stimulate an economic boom initiated by a race nicknamed, ‘the Yellow Peril’ by British colonists.

Nor were there any Californian gold deposits that saw Chinese junks sailed to port to name the province, ‘San Francisco of the East’ also known as Kum Sun or Gold Hill in the Cantonese dialect.

aaa9.jpg

Neither has Province Wellesley the amour and romantic provincial ambience of Provence in Northern Italy. There, sows are bred to sniff out musky truffles in Mediterranean woodlands. Valued like gold, truffles are shredded paper-thin and sparingly sprinkled over homemade, delicious pastas and spaghettis for the ‘oomph’ and much enjoyed by Italian families on special occasions.

The opposite holds true for Province Wellesley. While it held such a romantic, countryside name, it was renamed, Seberang Perai after the 1970’s.

My government then was in a passionate mood to erase all things colonial and opted for a local flavour. Pathetically, it sounds bad like a mouthful of verbal diarrhoea or a victim down with salmonella poisoning in latrine agony. Anyway, it is a phrase of a place I am not too proud to coo too sweetly.

The original topographic area of the province was mainly low lying, agricultural and forested land, with a couple of low, inland hills with patches scrub and wetlands. Naturally, it was left last to be developed in the tropical heat of a mosquito infested region.

bbb2.jpg

Fortunately, remoteness and late development gave longer tenure to bird habitats. It also allowed me a window period to checklist bird areas and put on historical record - prior to mid-2007, images of migratory and water birds seen at Bandar Perda wetlands area, Bukit Mertajam (above: top, migratory egrets; bottom, Chinese Pond Heron; right: near right Purple Heron; far right, Little Egret).

There were uncommon sightings of Greater Painted-snipes (Rostratula benghalensis), Red-necked Phalaropes (Phalaropus lobatus), Oriental Practincoles (Glareola maldivarum) and Brown-winged Kingfisher (Halcyon amauroptera), a family of Barred Buttonquails (Turnix suscitator) and Japanese Sparrowhawks (Accipiter gularis) to add to various species of bee-eaters, bitterns, kingfishers, munias, herons, wagtails, raptors and a resident Barn Owl (Tyto alba), bringing a total of more than a hundred species of birds at the peak of migratory season.

aaa26.jpg

Crepuscular birds - active feeding birds at dawn and dust had to be the signature species of Bandar Perda. Bird images shown here are the result of many predawn, solo visits and setting up of mobile mini hides at various birding sites (left: top left, Watercock; top right, Ruddy-breasted Crake; bottom left, Baillon’s Crake; bottom right, pair of Slaty-breasted Rail).

There were numerous occasions of a peaceful sit down of a take-away breakfast and hot tea-flask to observe Slaty-breasted Rails (Gallirallus striatus) hunt for their breakfast. They threw their heads back and stabbed their long beaks into damp paddy fields in search of embedded crustaceans. With hammer action, hardened shells of crustaceans, gripped by their bills, were smashed open against hardened rock surfaces (below top, Slaty-breasted Rail).

aaa13.jpg

Crepuscular birds were observed to roost in one field and breakfast stroll to the other. It provided a small window and précised time of opportunity to observe them as they crossed bunds or tracks in between fields (right bottom).

Being extremely skittish, these birds skirted the edge of paddy fields during feeding times and were rarely seen in mid-fields. As such, any slightest disturbance or predatory threat would give them the opportunity to run for cover.

In extreme cases, Watercocks (Gallicrex cinerea) were able to sense my presence a paddy field length or football field away. They posed to be most challenging of all water birds in digiscopy. The plumages of juveniles, females and non-breeding males were so well camouflaged in fallowed fields. My presence spooked them to flight before I realised they were there!

How did they know?

The sound of ploughing tractors roared in neighbouring paddy fields, churning out clumps of mud-encrusted larvae and worms to awaiting Eurasian Tree Sparrows (Passer montanus), House Crows (Corvus splendens), Common Mynas (Acridotheres tristis) and various species of egrets for fresh pickings.

1111.jpg

Occasionally, water birds such as this protected species of juvenile Slaty-breasted Rail (Gallirallus striatus) became destined for the cooking pot (left).

In spite of having to trudge in muddy terrain and having my boots sucked into mud and looking lost without owner’s foot, my passion for birds did not deter my fascination of observing feeding habits and behaviour of these water birds.

But… it is not me to be sitting and getting baked under the tropical sun for hours for birds to show up.

The stench of rubbish dumpsites and nuisance of mosquitoes swamping around and thirsting for new blood were no deterrent. I made peace pacts with hungry mosquitoes by the use of natural repellents and adorned the ghotra - a male Arabian headscarf which doubled up as a sunshade and dyed forest green.

However, any die-hard, large mosquitoes ‘dressed’ in black and white stripes attempting kamikaze stunts are something else to be reckoned with. They are potential carriers of Haemorrhagic Fever or Dengue Fever.

One has a choice. Smack those to death, take confession later or…. do a runner!

The only regret I have, had I been a birder much earlier to recee the birding site well, I could have chalked up a few more species of birds on my checklist. Unfortunately, my knowledge of birds then was inadequate to conclude a positive identification.

However, all is not lost. Just about in time, together with my visual partner, DG Scope, we take pleasure to share and air the final curtain show of the water bird series of Bandar Perda wetlands to readers of this blog (below: top left, Cinnamon Bittern; top right, White-browed Crake; bottom left, Purple Swamphen; bottom right, White-breasted Waterhen).

Alas! Development arrived.

With it, came cranes, bulldozers, trucks, and machineries for road works etc. changing the landscape, replacing agricultural lands with state of the art showpieces and grandiose buildings, some with eccentric architectural styles of mis-matched European designs with a concoction of Greco-Roman facades (below).

Development of a young nation like Malaysia, catering to the ever increasing demand in population growth, commerce and industry and prosperity takes priority above anything else.

It came with a heavy price tag.

One of the very expensive, destructive and irreversible price to pay is permanent and environmental habitat loss of wild animals, avian and flora life. Uncontrolled deforestation, human ignorance and greed, lackadaisical attitude, miscalculation, lack of prudence and foresight are other contributing factors.

Does it have to be done this way only?

a2.jpg

A young nation in the stages of development is like a young child learning to walk tall, have a few falls and bleed a little. What is to be expected of a toddler with a pacifier learning to discover him/herself?

What did a developing nation know about good governance, harmonious partnerships in sustainable development and stringent, environmental conservation practices in their early days?

The sad thing when dealing with bird-habitat environment is, consideration to conserve is often left last in terms of economic priority. It is preferred and more convenient to brush such issues under the carpet as there are no long term revenues in sight for the short sighted.

If current developed nations were given another chance to rebuild from scratch, would they plan the same as they did before? Instead of ending up breathing in concrete jungles, could they still be seen enjoying wild life nature by circumventing development projects around vital, conservative life lines?

Currently, bird watchers living in concrete jungles and yearning to view exotic species have to pay top dollars to breathe clean air in green lung areas. They have to leave home thousands of miles away to become tourists and fly in iron birds to walk in tropical rain forests reserves.

Isn’t it uncanny that developing nations are making haste to chop down their trees at super speed to create an artificial environment; copying developed nations and catering to a greedy, misconstrued concept and ugly word call, ‘ECOTOURISM’?

Or, the madness of isolated cases where humans have become so pampered in calling government agencies to summon and axe a tree just because fallen leaves were added chore for a housemaid?

Let’s listen to the finale chorus of three House Crows (Corvus splendens) named, GO, GOING GONE crooning to LONGFELLOW, the Purple Heron (Ardea purpurea) (top left))

GO, GOING, GONE seen perched on a bare tree,
Say GO and GONE, ‘Where have all the trees gone?’
GOING answered to GO and GONE perched on a bare tree,
‘They have all gone, to build concrete trees 200 feet long.’
So too, GO, GOING, GONE will gonna be going gone.

A last peep… as the final curtain descends on Bandar Perda wetlands (above right: top and bottom).

"You can know the name of a bird in all the languages of the world,
but when you're finished,
you'll know absolutely nothing whatever about the bird...
So let's look at the bird and see what it's doing - that's what counts.
I learned very early the difference between knowing the name of something and knowing something."

Nobel Laureate Richard P. Feynman (1918-1988)
