Back to Birding with the Cuckoos of Air Itam Dalam

Whenever i see a cuckoo i would try to take lots of their images as possible. They are after all one of those 'difficult' birds to be identified. You do not need to have great photos of the bird but as long as the subtle/prominent features can be seen you should be able to identify them or perhaps with some help from an experience birder.  I went again to Air Itam Dalam instead of Sungai Sedim forest recently in view of the weather and its shorter distance from my home. There are always some aura of mystery at this place i.e you will always expect to see something different each time you step into the area. This time three types of cuckoos were seen, however only two species were photographed. The first been an Indian Cuckoo.

Indian Cuckoo (Cuculus micropterus)
According to Craig Robson's (2005) and Allen J's (2012) field guide, a female Indian Cuckoo has rufescent wash / rufous tinge across breast. Here you can see the feature and therefore the image suggests that it could be an adult female Indian Cuckoo.



According to Medway and Wells (1976), this cuckoo species is most active from January to August but since this cuckoo was seen in December so it might just be an early visitor here.



In flight i have noticed that it has quite sharp arched wings, something which you will also see in 'Nightjars', 'Frigate birds' etc. This bird was silent through out which would normally be expected of passage migrants/winter visitors.



It was also quite aggressive - chasing a 'Common Flameback Woodpecker' (Dinopium javanense) straight down to the water. I believe it may be trying to prevent the woodpecker from getting near to the 'Pin-Stripped Tit-Babblers" (M. gularis) which a few have been observed near the Indian Cuckoo and may be presumed looking for a suitable nesting site.


The second cuckoo bird seen here was even more interesting and it was presumably an Oriental Cuckoo !   Ever since King (2005) described the oriental cuckoo (Cuculus optatus) as two separate species i.e Himalayan Cuckoo (C.saturatus) and Lesser Sunda Cuckoo (C. lepidus), the taxanomy of this cuckoo species has yet to be confirmed until todate. A quick check on Birdlife International site reveals that the oriental cuckoo (C. optatus) taxon is no longer recognised. However most of the checklist available todate and at the point of typing recognised C.saturatus (Himalayan Cuckoo) and Sunda Cuckoo (C.lepidus) in their database. Here are the latest checklist which you can refer to:

i)   Avibase database - version May 2014
ii)  Birdlife International - version 06.1 (Feb 2014)
iii) Clements - 6th ed., (6.9), 2014
iv) eBird - version 1.55
v) Howard & Moore - 4th ed.
vi) IOC World Birdlist - version 4.04

Note: apparently the above checklists also have "C.optatus' in their listing ! Aduh ! PENING KEPALA !!


Could this be a Himalayan Cuckoo (Cuculus saturatus)?

Just like the Indian Cuckoo it had remained silent but it perched quite high up on an exposed trunk. Due to the weather condition, i had to increased the ISO metering to see its features otherwise it would just appear as a black dot on the screen! According to Wells & Becking (1975) and Payne (2005) as cited in {Lindholm and Linden (2007), Forktail 23: 12 -16}, the Sunda Cuckoo occurs as a resident on the Malayan Peninsula and Indonesian islands. In more recent times, Allen J (2012) described that migratory population tend to frequent low elevations. So this cuckoo at Air Itam Dalam area may had been from the northern migratory populations (i.e from Central Asia, the Himalayan mountains, Japan and China) because the resident population in Peninsular Malaysia usually occurs above 900 m (Allen J & Pearson, 2012). (Note: it was reported that Seberang Perai area which consists of Air Dalam Forest is only 541 meters above sea level)

If this was indeed C. saturatus or a C. optatus then it should be the first reported sigting at Air Dalam Forest and probably just one of a few been spotted outside its hill or mountain playgrounds (as per B.i.W record). Although DNA analysis has been recommended to scientifically identify this species but how i wish that this cuckoo bird can be described as how some Malaysian birders described Swinhoe's snipe (G. megala) and Pintail snipe (G.stenura) as "Swintail Snipe" !! Malaysia Boleh ! I am sure you can too !

Herping with MNS Herpetology Group - Nov 2014

In your younger days you might have done some crazy stuff like climbing up Bukit Tabur in the middle of the night, scuba diving in the sea full of sharks, going camping alone in a remote place or perhaps going out at night to look for frogs and snakes in the jungle! Fast forward 30 years later, i kinda rekindled my childhood adventures by joining the MNS Herpetology Group in one of their outings recently. The rain came just before the trip but it did not deter 21 enthusiastic adventures including a few children to gather around for some good outing.

Oriental Whip Snake (Ahaetulla prasina)
Oriental Whip Snake (Ahaetulla prasina)
Even before we set for the trek, our group leader Steven Wong has found this common whip snake. The children got really excited seeing their first wild snake. 

It looks menacing but it is totally harmless to humans.

The kampung name for this snake as i can recall was 'ular lidi' while some book also named it as 'oriental vine snake'. After a few photograph sessions, the snake was released back to its habitat. The good news was that we also saw another whip snake of the same genus not too far away.

Parents and mums getting their children all prep up for the excursion. Fortunately the rain stopped at 9.20pm.

Herpetologist in action and watched closely by future herpetologists !  Whether is for fun or to eliminate the fear of snakes (ophidiophobia), it was heart warming to see that parents are encouraging their children to join such trips. 

And here is what the group leader has got for them - a handful of frogies. The enthusiasm and tenacity shown by the group leader in explaining and getting the subjects in hand was really appreciated by the group.  

Common Grass Frog (Fejervarya limnocharis)
This frog was indeed found among the weeds and was said to be the favourite food for ikan haruan (snake head fish). 

Common Wolf Snake (Lycodon capucinus)
This was the second snake found in this trip. 

One thing i have learnt from this trip was that not all poisonous snakes have triangle shaped head - cobras (naja naja) and coral snakes (Calliophis) do not have triangle shaped heads. Fortunately this wolf snake is not poisonous but it will not hesitate to bite if annoyed as i was briefed.

There were more frogs than snakes in this trip and here are some of them:
Lesser Stream Toad (Ingerophrynus parvus)
This was the only lone toad found in this trip.

Tanah Rata Frog (Limnonectes nitidius)  
This frog was initially thought to be found only in Tanah Rata, Cameron Highlands, 
Malaysia but subsequently it was reported that it can also be found in quite a number of places.

Rhinocerous Frog (Limnonectes plicatellus)
You can see a small bulge on its head (between its eyes) where it got its name from.

White-lipped Frog (Hydrophylax labialis)

Another common Grass Frog i believe. Look how well it blended with its surrounding.

Besides frogs and snakes we have also seen other creatures of the night like these ones:
Common Orb Weaver Spider

Giant centipede 

Note: the above centipede is called: "Malaysian Cherry Red Centipede" (Scolopendra spp)

Marbled Bent-Toed Gecko (Cyrtodactylus quaddrivirgatus)

Green Crested Lizard (Bronchocella cristatella)
I think this cicak is half asleep.

Being a birder i did look out for roosting birds, owls etc but unfortunately did not see any. I did however heard a nightjar calling (most likely a large tailed nightjar) (caprimulgus macrurus) as well as a call which sounded like coming from an OMR (Oriental Magpie Robin). Oh yes you can hear lots of other insects' calls in the night and some of which may be quite intriguing. 

Overall  i think everyone was very happy in this trip especially the children.


Birding here and there from February to March 2024

 Not many birds appearing at my local patches. I probably need to travel further to see more birds. Green-back Flycatcher Male Quite a frien...
