Get Out of Our Tree Hole Nest!

Nesting Wars at Dairy Farm Nature Park

The tree hole “nest” near the top of a dead coconut tree at Dairy Farm Nature Park was the centre of a real estate war between a pair of Banded Woodpeckers, a Red-crowned Barbet and a young Monitor Lizard when I visited the park on 17 July.

This particular hole was most probably excavated by the woodpeckers. Both were seen putting in the finishing touches to the nest throughout the whole morning. Each woodpecker took turns to clear the interior and getting comfortable inside.

Each woodpecker took turns to clear the interior of the nest hole.

But just after noon, a Red-crowned Barbet flew in and chased the woodpeckers away. There were no resistance. It seems that both the woodpeckers were afraid of the barbet and did not wish to pick a fight with it.

But the barbet did not seem too interested in occupying the nest. It went inside for a short while before flying off. From its clumsy attempts to perch on the trunk and it appeared to be a young bird. So it may not be looking for a nest hole to breed.

This surprising aggressive young Red-crowned Barbet chasing the woodpeckers away.

The woodpeckers returned only after the barbet left, happy to reclaim the nest. All this drama was being watched by a young Monitor Lizard at the base of the tree. Some friends told me that the lizard had been seen crawling into the nest before. My guess is that it was more interested in the eggs than the nest.

The Barbet did not seem too interested in the nest.

As with the nest hole at Pasir Ris Park, the woodpeckers did not have an easy time reclaiming this nest. Only time will tell if they will be able to raise a family here.

PS. This tree hole nest seemed abandoned when I checked it a few weeks later. Glad if anyone can provide an update.

Snakes Alive! at Singapore Quarry.

Birding can be rewarding even if the target birds do not show. Last Sunday evening 12 August, I went down to look for the Barred Eagle Owl that was seen by the road leading to the Singapore Quarry. Most fortunate to bump into Geri Lim who was looking for Wagler’s Pit Viper further up the road.

Pit Wranger Male Singapore Quarry

It turned out to be a male, about a foot long, curled up among the leaves of the “toilet paper tree”. The green color blends in well with the tree making it hard to find. According to Serin Subaraj this is an adult which is much smaller than the females. They are nocturnal, arboreal, venomous and can stay in the same place for days waiting for its prey.

1-P8134827

Coincidently, there was another Wagler’s Pit Viper further down the other end of the road. This was a much longer and larger black and yellow female,  It has been here for days, resting on a thin branch about 2 meters up. It may have eaten a rat or some small prey from the look of its bulging belly.  Mostly found in matured forest in the confines of CCNR, with frequent sightings at Bukit Timah Nature Reserve.

Walking back with Lim Kim Keang and Veronica Foo, we were taken back a bit when a 2 meter greyish brown snake slide across the road right in front of us. It has a cobra like head but a pretty net-patterned tail. Serin Subaraj identified it as a Keeled Rat Snake, a uncommon non-venomous, diurnal and terrestrial forest inhabitant.

Racer Singapore Quarry

By now, we were feeling rather chaffed, seeing two great snakes within minutes. I told them that that the chances of seeing a third snake this evening will be like striking 4D. As we walked further down, we heard a ruckus coming from one side of the road. Then we saw two very agitated squirrels and an Olive-winged Bulbul scrambling around and calling frantically. We knew that this unusual behavior meant that another snake was around.

Sure enough a snake slide out of the grasses on to the road. It is about 2 meter long, all green except for a reddish-brown tail. Kim Keang identified it as a Red-tailed Racer, an arboreal non venomous snake that can be found in our central forest. It hunts in the day and takes birds and small mammals.

Red-tailed Racer Singapore Quarry

This is the first time I came across three snakes within minutes of each other and outside of the central forest as well. Could the current hot weather be driving them out into the open urban surrounding? This may also explain why the Barred Eagle Owls breed here where their prey are plentiful.

Jungle, Tree and Tit Babblers of Panti.

Jungle, Tree and Tit Babblers of Panti.

“Babblers are the most infuriating group of birds to shoot”, Morten Strange, retired professional bird photographer once told us. We cannot agree more. They are sulking, confining and always on the move inside the dark under storey. You hear them calling more often than you will see them. Getting a good look was enough to make your day. You will need persistence, quick fingers and lots of luck to get decent photographs of these lowland forest babblers.

Much easier to zoom in on the birds at Panti’s sparsely wooded second clearing with from left Milton Tan, Alfred Chia, Veronica Foo, Patricia Tiang, Jimmy Chew and the author. Photo: Lim Kim Keang.

The lowland rainforest of Johor has 20 species of these Babblers. (See list below). You can find all of them at the Gunung Panti Forest Reserve. Some of the more common ones like the Black-capped and Chestnut-winged Babbler are more conspicuous and vocal, while others like the Grey-breasted are rare. They are mostly insectivorous, moves in family groups and non migratory. Forest fragmentation is a threat.

I was lucky during some of my recent visits to find a few either having a bath in the open, nesting building, feeding its chicks or popping out in the open for a split second. Here are some record images of them.

Chestnut-winged Babbler with nest material

This pair of Chestnut-winged Babblers were busy gathering leaves to build their nest and did not care too much about our presence. We have a small vulnerable population in our Central Catchment Forest and they are not so easily seen.

Fluffy-backed Tit-babbler 12.6.18

We found this Fluffy-backed Tit-babbler bringing back food for its chick. Even so they were very cautious and we had to stayed at a distance before they will feed the chick.

Black-throated Babbler

On hot mornings, the Black-throated Babblers cannot resist a dip in the puddles of water at the quiet tracks. Inside the undergrowth, it is hard to get the sheen of their plumage.

Black-capped Babbler

The Black-capped Babbler is one of the most vocal and common babblers in Panti. Still it is not easy to see them as they prefer to stay inside the forest. Best is to wait for them to fly out into the open and hope to snap it in the split second.

1-_4210787

The Horsfield’s Babbler resembles the Abbott’s Babbler except for the faint streaks on its breast. Theirs were the first calls you used to hear as part of the dawn chorus at the first clearing. Unfortunately they have moved further in and are hard to find these days.

Rufous-crowned Babbler

Rufous-crowned Babblers are very jumpy and prefer to stay inside the dark mid storey. Light is always a premium for getting any good shots. Looks similar to the Scaly-crowned Babbler except for the grey legs.

White-chested Babbler

The White-chested Babblers inhabit the freshwater swamps of the lowland forests. Uncommon in Panti so great to have this record shot. It is very rare on mainland Singapore, last seen and heard in the early 2000s.

The “Little Brown Jobs” of Panti Forest.

Not all forest birds are as colorful as the Trogons or Barbets. Some are just plain and drab looking and obviously does not attract the same attention from bird photographers.  I would like to highlight a few of these under the radar “Little Brown Jobs” that we photographed at Panti Forest last month.

Grey-breasted Spiderhunter

The Grey-breasted Spiderhunter is one of the rarer spiderhunters at Panti. It has a all grey underside with faint streaks. The eye-rings are absent. Usually found sipping nectar from flowering trees by the roadside, they also has shorter bills. Was a former resident in Singapore.

Plain Sunbird

The Plain Sunbird is a very rare resident of Singapore with the last confirmed record on 25 January 1986 when a male was seen at Senoko. There were unconfirmed reports from CCNR and Rifle Range Road in 1998 and 2006. This is another species that is attracted to certain blooms in the forest. The male can be identified by the small bluish patch on its forehead.

Buff-vented Bulbul

The Buff-vented Bulbul is another very rare resident of Singapore. All the sightings so far were from Bukit Timah NR. Best chance of finding this bulbul is when the ficus tree at the summit is fruiting. They are common at Panti especially along the “old road” feeding on the berries and figs there.

Spectacled Bulbul.

 

It could be the low numbers why this Spectacled Bulbul went extinct in Singapore while the Red-eyed and Cream-vented Bulbuls survive today. With a healthy population in Panti, there is always a chance they will make a comeback. The orange eye-ring is a good id feature for this bulbul.

Sentosa’s Undersea Wonderland.

Sentosa’s Undersea Wonderland.

I did not know that there are sea spiders in our waters until I saw Lena Chow’s post. I decided to swap my birding trip for some beachcombing at Sentosa last Sunday to look for them. We had a super low tide that weekend. Large expanse of the seabed was exposed. Corals, sponges and trapped marine life were left high and dry. Perfect time to see them without getting wet.

1-20180617_090344

Great to see some patches of Taped Sea Grasses growing here. Labrador at the background with Pasir Panjang Container Port in the distance.

Unfortunately I did not find any sea spiders. I was told that they are really small and hard to find. But this was well compensated with other weird and wonderful marine creatures like this Brittle Star found in a tidal pool.

1-P6252162

Brittle Star. ID welcome.

In the same tidal pool was a pair of mating Common Sea Stars pointed out to me by Lena. They were moving around during the whole mating session.

This Goby has a red forehead but despite of this feature I cannot find the species.

Stone or Thunder Crab trying to hide and blend into the surroundings. 

1-P6252120

This medium size Hairy Crab is common here. Its color and appearance made it hard to detect if it stays still.

Orange Fanworms have to adapt to surviving out of the water at least for a few hours.

Soft corals and sponges make up the diverse forms of marine life here. They come in different shapes, forms and sizes.

Leathery Soft Coral

Jabba the Hut, a character in Star Wars must have been inspired by this huge Soft Leathery Coral. According to Lena this particular one has been at the spot since she started exploring here exploring this beach many years back. She likened it to pig-skin.

1-P6252032

This another soft coral, the Broad Leathery Soft Coral. It has only one type of polyp ending in eight tentacles. The whole coral has an overall blue tinge.

These are all Silvery Blue Sponge at different stages of growth. The left clump looks like a staghorn fern 

1-P6252058

This is a Barrel Sponge even though it feels hard to the touch.

Hard corals are more easily recognised.

Thin Disk Coral

The Thin Dish Coral has many different shapes, this one looking like a cup.

1-P6252104-001

Jigsaw Mazed Coral has this intricate ridged patterns on its round surface.

1-P6252115

The Hexagonal Favid Coral is of the same size and shape as a rock melon.

1-P6252160

Haddon’s Carpet Anemone greenish color made it attractive to collectors.

1-P6252149

The Giant Carpet Anemone on the other hand has an abstract feel to it.

1-P6252062

Adding colour to the seafloor is this Halymenia Red Seaweed.

Not able to find any references for this sea plant in the sea weeds and sea grasses indexes.

Southern Ridges – A Bird’s Eye View

Southern Ridges from the Air.

Today the Jiak Hong Birder takes you up in the air for a bird’s eye view of the Southern Ridges, more precisely the Forest Walk section from Gillman Barracks to Telok Blangah Hill. These photos were taken with the Samsung 5 handphone.  The lucky residents of the apartments facing the Southern Ridges get to enjoy these million dollar views everyday. And what a view! I listed some of the birds that were reported at this part of the Ridges as a footnote. Be free to add in any that I missed out.

The Critters of Dairy Farm NP

Joined my friends for a walk at Dairy Farm NP this Sunday morning after hearing of a sighting of the Black-crested Bulbul there by Geri Lim. But it did not show. A few of us had brief glimpses of the Greater Green Leafbird feeding on the White Mulberry. Other than that it was rather quiet. So we ended up looking for the other creatures at the Park.

Stink Horn Fungi

Thanks to Meilin Khoo for showing us this Stink Horn Fungi growing by the roadside. Unfortunately the sweepers unwittingly broke half of the “skirt”, but it was still a good find. The smell of rotting flesh of the spore head attracts flies and other insects, and they in turn help to disperse the spores.

DFNP

The Nephilengys malabarenis was first found at the Malabar Coast of South India. This particular specimen was spotted by Art Toh hanging under the pile of Tembusu logs at the hilltop at its web. It quickly moved away just as we were trying to get some shots.

DFNP

Assassin Bug lived up to its name. This one found a male Golden Orb Spider. It will inject vernon to kill the prey and then suck out its dissolved remains.

Oriental Whip Snake DFNP

A pair of Oriental Whip Snakes by the Wallace Center provided us with some distraction. This one was moving its head up and I managed to catch a view of its underside. Mildly venomous, it can take small birds like the Pygmy Sunda Woodpecker.

St Andrew's Spider DFNP

St. Andrew’s Cross Spider rest with each pair of legs stretched out forming a cross. They also spin zig-zag whistish webs in the form of an X just where the legs rest like in this photo. Females are larger than the males.

Malay Viscount

A Malay Viscount, a common butterfly at the park looks very similiar to the Horsfield Baron.
