The Varied Diet of the Yellow-vented Bulbul Chicks.

The Varied Diet of the Yellow-vented Bulbul Chicks. By Seng Alvin.

The ubiquitous Yellow-vented Bulbul Pycnonotus goiavier has to be the most common bird in our urban greenery. Its bubbly call is a welcome sound in our parks and gardens. If you listen carefully, they have different calls and alarms for different situations.

With two hungry chicks to feed, the parent bulbuls were kept busy throughout the day

I was lucky to come across a nesting pair at Pasir Ris Park this June and decided to document the food that the parents brought back to feed the chicks, and it was very varied.

Insects formed the main source of proteins for the growing chicks. Wasps from a nearby nest, a green grasshopper and a spider showed the variety of the feed.

My monitoring started on the 17th. I spent one to two hours each day between 8.00 am and 10 am photographing the the feeding process. Both chicks successfully fledged on the 22nd after a week of feeding.

Happy and well fed chicks about to fledge on the 22nd June.

For the first three days, the parents brought back soft and small insects that can be easily digested. Spiders and caterpillars were also a good source of proteins for the growing chicks. In the later stage, berries and figs supplemented larger insects like grasshoppers.

Squashed figs and berries will form the main diet of these frugivorous species when they grow up. 

In first part of the day, the parents will usually feed the chicks with insects. As the day progressed, they would start bringing back figs and berries to the chicks, for desserts? As there was a wasp’s nest nearby, they took full advantage of this ready source of rich protein insects. I wonder how do they neutralise the venom if any inside these wasps?

From my observations, their diet is not just varied but well balanced for the chicks to grow up as fast as possible to begin another generation.

Tree Nest Hole for Rent at Pasir Ris Park. II

Tree nest hole for rent at Pasir Ris Park II, by Seng Alvin.

After the bees left, the tree hole lay vacant for a few weeks. On 14 May, I was surprised to find a pair of Laced Woodpeckers back at the nest. Based on the tags on their legs it was the same pair of woodpeckers that were being chased out by the Red-breasted Parakeets last month. Maybe they were not able to find any suitable hole nest anywhere else or they really like the location and ambience of the park. Whatever is the reason I was happy to see them back. They seemed to be incubating their eggs which meant that another generation of woodpeckers will be gracing the park.

Five days later, I went to check on their progress. I saw a head popped out of the tree hole. I was expecting to see the woodpecker coming out, but it was a baby monitor lizard instead, much to my dismay. This tree hole had to be the most desired hole nest in the park. Both the parents did their best to chase the lizard off for over an hour but to no avail.

My guess is that the monitor lizard must have sniffed out the eggs in the nest and did not want to pass up a good meal. Again this is nature, each species is part of the food chain. I came back two day later to see if the woodpeckers will try again to use the nest, but looks like “game over” for them.

On 16 January 2018, I was on my routine morning birding walk along the mangroves at my back yard Pasir Ris Park, when I heard pecking coming from the tree nearby. It was a pair of Laced Woodpeckers excavating a hole on the tree trunk for their love nest. I was happy to see this as the last nesting here was in March 2015. For the next few days, the mummy woodpecker spent many hours hard at work at the nest hole.

On 23 January, when I went to check in the progress, I was surprised to find that a Red-breasted Parakeet at the nest hole. There were no signs of the woodpeckers. Parakeets also used tree cavities for their nests. Since they cannot excavate tree holes, the next best thing to do is to take over existing holes.

Fortunately or unfortunately, this tree hole was too small for the parakeet and they could not use it. But this did not stop the parakeets from coming back during the next few days to check on the tree hole. The Laced Woodpeckers were nowhere to be seen. It may be that the parakeets were too aggressive for the woodpeckers and they prefer not to pick a fight with them.

Both the parakeets and woodpeckers went missing for a while, until 26 February when the parakeet came back again to check if the hole got any bigger. It was still too small for it and it finally gave up. A little later that day I was happy to see the male Laced Woodpecker back at the hole. Will they now decide to use the hole to nest this time?

March and April came and went, but the both species seemed to abandon this tree hole. Did the woodpeckers find better location somewhere? Was there something they don’t like about this particular tree hole?

My conclusion is that this is one of the mysteries of nature and we just have to accept it.

 

 

 

The Pasir Ris Pied Fantail Story

Contributed by Seng Alvin.

I have been watching the nesting of the Malayan Pied Fantails Rhipidura javanica at Pasir Ris Park since 2014. All have been successful and none were invaded by the cuckoos. There was single nesting in 2014 but two in 2015 and last year.

19667619_1401944123217714_531500128511659950_o

In January this year, a pair was again seen building a nest. By March two chicks were brought up successfully to grace the park. On 17th April I was a little surprised when I saw an adult bird sitting on the same old nest. They must have just bought this “resale unit” and moved in. I knew that they will be nesting again.

19402001_1401944313217695_3647856079902138388_o

But just as they were about to settle down, they decided to move to a “BTO” nest nearby. The poor father must have thought that he could take it easy this time round by reusing the old nest. It was not to be. He built a new nest around April/May just like any daddy would to please the mummy.

The new nest which look rather precarious.

Maybe it is the neighborhood, but sometime in early June I found the pair back at the old nest. It could be that the old nest is at a more convenient neighborhood close to the foraging grounds? It is still location, location, location even for the birds.

19488932_1401944413217685_6562132331921403512_o

Back at the old nest in early June. 

After all the hard work, they raise only one chick this time round. This is for the better as they can bring this one chick up without much stress.

19511247_1401944589884334_8940549613624020334_n

Only one chick this time around, less stress for the parents.

On 29th June, the chick fledged. The decision to stop at one paid off. Unless we tagged the adult birds, we cannot be certain if this pair are the same as the earlier pair that make Pasir Ris Park their home. I am really glad that despite the number of park visitors roaming around, these fantails are able to adapt and thrive here.

Year of the Red Jungle Rooster

Contributed by Seng Alvin.

As we will be welcoming the Year of the Rooster in a few days time, there is no better time to write something about our Red Jungle Fowl, Galus galus, without which we will not have our Hainanese  Chicken Rice.

They are now seen all over the island from parks and gardens to our housing estates. But they were not recorded by our earlier authors up to the late 70s. The first record was from Pulau Ubin in 1985/86 from observations  by Lim Kim Keang, other birders and residents. This population, likely from Johor, had since established itself. Pulau Ubin is still considered the stronghold for this species. The first mainland record were two females seen at Poyan on 29 January 1998. (SINAV 12.1).

The spread of this species together with introduced stock and escapees to the rest of the island have resulted in hybrid birds roaming all over our parks and gardens. The danger will be a dilution of the original species in Ubin if it has not happened yet. Another concern is the spread of bird flu if it surfaces in Singapore again.

Pasir Ris Park has a few families of the Red Jungle Fowls, with 30-40 birds, thriving in this mangrove parkland. The most recent was this hybrid family where the mother was a domestic hen with a complete white plumage. The father seems to be a Red Jungle Fowl. Why did it choose to mate with a domestic hen instead one of the wilder birds around?

It was seen hanging around at a distant to the mother and her seven chicks but did not feed with them. This strange behavior may be of rejection by the hen and the reluctance of the father to abandon the family or normal for the mother bird to bring up the chicks alone. What do you think? Interestingly the chicks are both white and brown taking the genes from each parent. I will monitor this family and seen how the chicks will turn out when they become adults.

Gong Xi Fa Cai to all.

The Survivors of Pasir Ris Park.

Contributed by Seng Alvin. Photos Credit: Seng Alvin.

Pasir Ris Park at the north-eastern end of Singapore with its riverine mangroves and wooded parklands  has long been a favourite place to bringing up babies, baby birds to be exact. Malaysian Pied Fantails, resident cuckoos, sunbirds and of course the star of Pasir Ris, the Spotted Wood Owls are some of the species that breed at the park. Raiding parties of Oriental Pied Hornbills from across Pulau Ubin made foraging sweeps now and then for nesting chicks to feed their young during the breeding season.

But the park may be  turning into an infirmary and home for injured birds. Long time resident “one-eye Jack” our darling Buffy Fish Owl have been rehabilitating  in the mangroves for some time now.

30th April. First photo of the one-legged Olive-winged Bulbul inside the Mangroves at PRP.

Early this year, on 30th April, I photographed an Olive-winged Bulbul, Pycnonoyus plumosus, inside the mangrove area but did not think much about the photo. Then a month later I came across another Olive-winged Bulbul at the mangroves and realised that it also had only one leg. Digging out the photo of the bulbul I shot in April, I realised that it was the same bulbul. Was it crippled at birth or did it suffered some mishap later on? I have no way to know but was happy to see that it was surviving.

I was out on the evening of August 2nd at the bridge waiting for the Stock-billed Kingfisher to start fishing for dinner. A bulbul distracted me and I fired a few shots ( with the wrong settings). Later as I was about to delete it I found something strange with it. Just to make sure I was not seeing things, I posted it on Bird Sightings FB Group and asked if anyone sees any thing different with this bulbul. Keen eyed Benny Lim responsed that it was one legged!

August 2nd shot near to the bridge while waiting for the Stork-billed Kingfisher. Can you see the missing leg?

Bingo, I now have a third photo of the same bulbul, which means that it has survived almost four months now. Wang Heng Mount proclaimed it as a winner and survivor. This guy is a mighty said Millie Cher and Jeffrey Long called it “a fighter”.

To me it is all the above and we should all be inspired by these survivors at Paris Ris and wish them a long and happy time at the park.

 

Collared Kingfisher fledglings at PRP

Bird Nest Fern SAlvin

Kingfishers have large heavy bills to catch fish, lizards  and grasshoppers. They are not suited to build nests like bulbuls and sunbirds. So they have to adapt and used holes to nest. As their bills are not as strong as the woodpeckers, they cannot dig nest holes in the tree trunks and branches. Instead they look for softer medium like old termites nests, plant and fern roots. The White-throated Kingfisher digs holes in the sides of earth embankments for their nests.

Parent Collared Kingfisher trying to get the chicks out of the nest hole

On 29 March, I came across a group of photographers shooting a Bird Nest Fern at Pasir Ris Park. Out of curiosity, I joined them. They were shooting at a nest hole at the base of the fern. They told me that it was the nest hole of a pair of Collared Kingfishers, Todiramphus chloris. This is something new to me. The parent bird flew back after a short wait but did not bring back any food. We later found out that it was trying to lure the chicks out of the nest.

Collared KF 2 SAlvin

The first chick fledged on 29 March 2016. Looks very much like the parents except for a shorter tail.

Collared Kingfishers are the most common kingfishers in Singapore. They are normally found near our coast and mangroves but some have moved inland for a higher protein diet when nesting. They have two breeding seasons, January to May and August to September.

The chicks were already fully grown and I was just in time to see the fledgling of the first chick. The second chick fledged the next day. They have short tails but already assumed the white and blue plumage of the adults. So happy to have another pair of these kingfishers making their home here.
