Large-tailed Nightjar (Caprimulgus macrurus) Call Behaviour

posted in: bird, Calls, Large-tailed nightjar | 0
Image 1: The throat and neck of the bird would get considerably distended when calling.

I arrived very early at the Matang Mangrove Forest Reserve, Perak on 2nd February 2023; it was still dark at 7.00am. There was a male Large-tailed Nightjar (Caprimulgus macrurus) calling out while perched on the electrical wires, with some street lights nearby. The Nikon Z9 camera I use has an electronic viewfinder that allows for the brightness levels to be set higher. This enables good observation in very low light settings. I noticed that the throat and neck of the bird would get considerably distended when calling. I used high ISO settings (51200) to document this (see image, cleaned using Topaz Denoise). 

In addition, the white throat patch would be expressed better as the bird called out.  

Image 2 of the Large-tailed nightjar.

There was a female Large-tailed Nightjar watching nearby. The calls made were those I have previously observed as part of courtship behaviour (Amar-Singh HSS 2019). A call recording I made from Matang Mangrove Forest Reserve, Kuala Sepetang, Perak can be heard here: https://xeno-canto.org/778223

 Once the series of calls was completed the pair flew off together.

 I wonder if the white throat patch that ‘flashes’ as the bird calls (much better appreciated in person) is part of the courtship display? It is a feature that can be appreciated in low light, especially by these nocturnal birds.

Crimson-breasted Flowerpecker (Prionochilus percussus) collecting spider webs for nest construction

posted in: bird, Collecting spider webs | 0

I was at the Kledang Saiong Forest Reserve on 30th January 2023 when I spotted this female Crimson-breasted Flowerpecker (Prionochilus percussus) collecting spider webs for nest construction. It was not looking for spider prey. It would extend the body forward, open the beak wide, then brush it through the spider web and snag some strands. It did this action a few times and then went to another spider web to get more material. The nest and the male partner were not observed. 

First image shows the behaviour. The second image shows the collected spider webs in the beak.

Image 2: Female Crimson- breasted flowerpecker with the collected spider webs in the beak. Sayong Forest. 30 January 2023.

Birds are well recognised to use spider webs as part of the nesting structure (see a previous record from me: Amar-Singh HSS 2016). Spider silk acts as a ‘glue’ or ‘tape’ to hold parts of the nest together and allows flexibility for some expansion. 

Crimson-breasted Flowerpecker nests are poorly described. Wells (2007) states “not described” locally; Cheke and Mann (2001) say nest “unknown”. Birds of the World (2020) offer a description of the nest as “a pear-shaped bag, circular entrance 2·5 cm in diameter, protruding rim around entrance (but no porch), constructed from reddish vegetable down, lined with fine roots, and decorated with caterpillar excreta, lichen, moss, roots etc.” No mention of the use of spider web in the construction.

Blue-billed Duck

posted in: bird, ducks | 0
                                                                                    Australian Blue-billed duck ( Oxyura australis )

Wong Kais spotted a single male Blue-billed duck at the Warrnambool Botanic Gardens on 30 October 2022.  It was very avoidant in behaviour and only a few quick shots and a short video were obtained after 30 minutes. The photo gallery below is a sample of the photos of this elusive duck.

Image A : Australian Blue-billed duck (Oxyura australis) ( Warrnambool Botanic Garden, 30th October 2022). Body is deep reddish brown color, head is black, bill is powder-blue. Black eyes are well camouflaged by the black head. It is a diving duck that usually sits low in the water, with its short spiky tail submerged. They are rather shy. When they notice an observer nearby, they will frequently dive or sneak into the reeds, making it difficult to obtain a good picture.

                                                 Australasian Grebe ( Tachybaptus novaehollandiae )

( Lake Pertobe, Warrnambool, Australia. 6th November 2022 )

During my holiday at Warrnambool, I strolled around placid Lake Pertobe a few times and noticed the grebes going about their nest-building.  The breeding plumage made them stand out from the background.  I noticed a pair of these birds returning to a particular point amongst the plants growing in the middle of the lake.  Close observations for a period of time revealed a floating nest, with a bird sitting in it for varying lengths of time.

 

The photo gallery  and videos  documented the grebes’ activities amidst the goings on of other birds that shared this living space.

Image A: Tachybaptus novaehollandiae. Breeding plumage: striking yellow eye with central black pupil, a pale yellow teardrop patch sloping diagonally from lower front corner of eye towards base of lower beak, a mostly black head, a bright reddish brown, broad stripe of color extends posteriorly from each eye towards the nape and downwards along each side of the neck. The beak is black with a white tip.

Juvenile Australian Magpies playing wrestling

posted in: bird | 0

A group of Australian Magpies (Gymnorhina tibicen) was observed gathered in the shade of a large tree at King’s Domain, Melbourne. Wong Kais observed them from a distance and decided to train his camera on them. They were rolling on the grass, leaping at each other, chasing, kicking, pecking and wrestling.  There was an absence of sound and fury and Kais concluded that it was not a bird battle. By the time Kais was ready to roll his camera, there were 2 birds left continuing with the friskiness.

When viewed on the computer back home, the 2 birds could be seen to have grey scalloped patches on the white back, indicating juveniles or females. There were moments when one bird rolls onto its back and sticks its legs up straight into the air.

“A magpie, particularly a juvenile, may also fall, roll over on its back and expose its underparts.[77] Birds may fluff up their flank feathers as an aggressive display or preceding an attack.[78] Young birds display various forms of play behaviour, either by themselves or in groups, with older birds often initiating the proceedings with juveniles. These may involve picking up, manipulating or tugging at various objects such as sticks, rocks or bits of wire, and handing them to other birds. A bird may pick up a feather or leaf and flying off with it, with other birds pursuing and attempting to bring down the leader by latching onto its tail feathers. Birds may jump on each other and even engage in mock fighting. Play may even take place with other species such as blue-faced honeyeaters and Australasian pipits.”  https://en.wikipedia.org/wiki/Australian_magpie

Kais concluded that he had witnessed a family group enjoying a bit of family time in the cool shade.

View the video below to see what Kais observed.

Willie wagtails harass Australian raven

On 7 November 2022, Wong Kais witnessed an epic bird battle that lasted 30 minutes. He was walking along Liebig Street, Warrnambool, Victoria, Australia when he heard a lot of bird flaps and flashes of black and white darting across the top of a roof. He stepped off the pavement and found a position that allowed him to film the kerfuffle.

Two little birds, Willie wagtails, were taking turns to attack an Australian raven, Corvus coronoides.  At other times both willies attacked at the same time by swooping down in mad-hatter fashion.  The raven stayed put and defended itself against the determined willies. Sometimes the raven turned around to fight off the feisty little birds, at other times it tried to peck at the pesky attackers.  For a short while, a third willie joined in the affray but eventually went on its way.

Willie wagtails, Rhipidura leucophrys,  breed from August to January. The willies were probably defending their nest nearby. These little birds have been documented to fight off Magpie Larks, Magpies, and even Wedge-tailed Eagles.  Wong Kais observed a pair of these little birds harassing a Kookabura at the Blue Mountains and tt Continental Park, Port Elliot, South Australia he witnessed a pair of Willie wagtails mob an Australian magpie (2 July 2022).

Warrnambool holiday

posted in: Miscellaneous | 0

Wong Kais explored Warrnambool, Victoria, Australia from 25/11/2022 to 8/11/2022.  Warrnambool is a city along the Great Ocean Road, sandwiched between the famous towns of Port Fairy and Port Campbell.  A V/line train service runs from the Southern Cross Station, Melbourne to Geelong and terminates at Warrnambool. During his stay he was soaked and inconvenienced by the frequent spells of  rain drizzle which hampered his photo taking, and had to don a raincoat whenever he stepped out of the accommodations. On the few days when clear skies appeared, Wong Kais took in the scenery from the Cannon Hill Lookout as well as visit the Botanical Gardens designed by William Guilfoyle, who was then the Director of the Melbourne Botanical Gardens.

The city is laid out neatly in typical style seen in Australian towns and cities.  Warrnambool has round-about at almost every road junction and this makes the city stand out from other towns/cities he has visited so far. Drivers are law-abiding and considerate, always giving way to pedestrians who cross at designated spots near the round-about.

The city is well served by the usual big players : IGA, Aldi, Coles and Woolworths supermarkets. The fresh local produce requires little cooking and flavouring to bring out the best. Visitors are spoilt for choice of cuisine. Even Penang delicacies prepared by the son and daughter-in-law of a Penangite Peranakan can be savoured here in Warrnambool.  Wong Kais tried the delectable nasi lemak: amazingly fragrant rice in Malaysian style, the usual condiments and a side of fork-tender, juicy rendang from another cooking era. He indulged in lamb shanks at the Whalers Hotel and stuffed his face. He would like to try other cuisines such as Mexican, Italian and Vietnamese offerings on his next trip.

Tourist spots are within walking distance.  In this post, he shares photos and observations he made at the Cannon Hill Lookout and Botanical Gardens.

Cannon Hill Lookout

Cannon Hill Lookout offers panoramic views of Lake Pertobe and distant views of the Foreshore Promenade and Lady Bay. Visitors can view a display of cannons used during World Wars I and II, monuments commemorating Portuguese exploration of the South West and The Dirty Angel statue installed in 1925 in tribute to war veterans. Beautifully maintained footpaths with a downward gradient lead towards Lake Pertobe and Foreshore Promenade. Tour buses unload tourists at the spacious carpark here; locals take their lunch and tea-breaks while feasting on the views from the refuge of their parked cars.

Botanical Gardens Warrnambool (designed in 1879)

We entered a quiet and tranquil garden on a Sunday morning.  Beautiful tall trees, spring flowers in full bloom, a rotunda built in 1913, wide lawns and a pond populated by ducks and frogs, are all packed into 8.1 ha. Visitors can walk a circuit of the gardens in half an hour but there are plants spaced out in little niche corners that are worthy of one’s attention.

Wong Kais is hoping to visit Warrnambool again during the whale sighting months of June- September. The water off Logans Beach is a renowned whale nursery and thus a whale watching hot-spot. He also hopes to trek the Foreshore Promenade to Thunder Point and the breakwater. Maybe he will share more photos with BESGroup in the coming months.

Black-and-Red Broadbill Cymbirhynchus macrorhynchos

posted in: bird, Black and Red Broadbill | 0

These beautiful birds possess brilliant blue and yellow bills which are easily recognised in the field. The females are similar to the males except for a slightly smaller size.

Residents of forests and prefer areas with access to rivers, water edges, mangrove areas with Sonneratia trees and salt-water plants like Pandanus sp.  Untidy nests jointly built by mating pair.

Feed on arthropods, berries, molluscs, crabs and small fish.

Locally extinct but rare visitors from Peninsula Malaysia drop by Singapore precincts, sending bird photographers into wild excitement.

Sim Chip Chye was tipped  by his buddy Art Toh of this rare sighting at 1600 hrs. Since he had missed the opportunity at Pulau Ubin’s Chek Java, he hurried to record this birdie in the mainland. By the time he picked up his gears, travelled there and brisk walked to the location, he walked pass many of his birding friends who assured him that the bird was still around. He reached the location around 1700 hrs! Lighting had diminished somewhat and the bird was rather fleet-winged and flying all over the tall trees. With the help of some buddies, he managed to take home some records of this lovely avian species that he had also missed during a trip up north some years back.

Hoverfly Monoceromyia javana mimics wasp

posted in: Arthropod, hoverfly | 0

Order       : Diptera

Subfamily: Eristalinae ( droneflies and allies)

Hoverflies, also known as droneflies, belong to the Insect Order Diptera characterised by one pair of wings (di: two; pteron: wing) and one pair of tiny wings known as halteres.  The halteres are modified hindwings which have flight  mechanosensory functions and stabilise flight events. Many of them hover around flowers and feed on pollens or nectar. They are good mimics of wasps and bees.

These flies have been known to pollinate orchids like Epipactis veratrifolia and slipper orchids.  Their larvae, known as maggots, may be terrestrial and perform pest control of aphids or feed on decaying plant matter; or aquatic e.g. rat-tailed maggots found in water bodies polluted with organic matter like sewage. Larvae of Microdon are adapted to live in ant nests and feed on ant larvae, their faecal pellets and pupae.

Soh Kam Yung shares his photographs of these flies, Monoceromyia javana, taken at Lim Chu Kang and Chestnut Nature Park.

‘Monoceromyia javana, a Drone Fly (subfamily Eristalinae) spotted in Singapore (Kranji Marshes) on 25 Dec. 2020. Soh Kam Yung thought it was a wasp at first until he took a closer look and realized what it was. Good mimicry.’

In Soh Kam Yung’s inaturalist account he writes:

Happy to spot this Monoceromyia javana at Chestnut Nature Park on 11 Oct 2021. It looks like a wasp from a distance, but it’s really a Hover fly, and a good wasp-looking mimic.
He received the following comment from a member with moniker ‘arbonius’:
‘Your photos show all the diagnostic characters for the species ID very clearly. This is a male (from the “eyes touching” at the top of the head).’

Long-tailed shrike frequents Bishan MRT station vicinity

posted in: bird, Long-tailed shrike | 0

Dave observed a lone Long-tailed shrike Lanius schach in the vicinity of Bishan MRT station on many occasions (Image 1). The bird is unafraid of people and allowed the photographer to approach it to a distance of 2 m.  It is often seen around noon, perched on the tallest wire of the fence (Image 2). On 31 December 2022 Dave observed it perching and scanning its surroundings in the shade of  small shrubs in the same vicinity.

    I just found a young dollarbird in the garden.. It seems to have left the nest too early and cannot fly yet. How am i to keep and feed it for a few days untill it can fly.???

    We have a small pond in our garden surrounded by trees and steep bedrock. The other day we saw a heron flying over and attempting to land – I guess to try to eat our small stock of fish. We managed to frighten it away before it landed, and have since installed trip wires around the pond in order to dissuade the bird. The amount of shelter around the pond means that a heron would have to land practically vertically. Does anyone know whether these birds have the agility to hover and land in this way, or do they always need a “glidepath” in order to land successfully?

    Today, at the former Bidadari Cemetery, there was a buzz about a sighting of a Grey Nightjar (Caprimulgus jotaka). I heard some birders say this nightjar isn’t commonly seen in Singapore. After some hunting, we spotted it asleep on a tree branch, some 15 m above ground. This was rather interesting as my previous encounters with nightjars have been on either terra firma or on low branches.

    Is this perching so high up the tree normal or is it unusual? I have posted a photo of it on my Facebook Timeline: https://www.facebook.com/photo.php?fbid=10151125012234135&set=a.108191464134.96538.617499134&type=1&theater

    Bird Sanctuary At Former Bidadari Cementry

    1)Which is the best spot in Bidadari cemetery for bird watch?

    2)Where this bird usually resident at?

    3)What are some of the rare bird species that can be found at Bidadari?

    4)Where is the particular hot spot for the hornbills, eagles, kingfishers and some of the rare migratory bird?

    5)Which part of Bidadari are richest in it wildlife?

    6)Can you name me the 59 migratory bird species found?

    Why not search the website using the word ‘Bidadari’ to obtain the information you need. There should be sufficient info in past postings to satisfy you.

    Hai, I just want to ask did anybody had an experience bring bird from oversea via MasKargo? Did the bird will stress at high altitude?

    Hi, I am new to bird photography! Could anyone advise a good pair of binoculars to get for this hobby?

    I ‘acquired’ a female Blue-crowned Hanging Parrot 5 days ago – was in a public place when the bird flew overhead hit the wall and dropped right in front of me dazed. I picked it up, it appeared unhurt but could not sustain it’s flight. I have since constructed a fairly large ‘cage’ for it, about 4ft x 2fx x 2ft and placed it there last night. I temporarily placed her in a normal bird cage until I had completed the build.
    From what I have read up, it’s a fruit, seed and insect feeder and also nectar, flower buds. It’s doing as well as it can on bananas, papaya, jack-fruit (didn’t touch the grape) and seeds (black and white sunflower and other smaller ones). It loves to bathe so I’ve gotten it a tray and from what I read it’s important to keep things clean as it easily succumbs to infection.
    Does anyone else have any useful experience and sharing on it’s upkeep? I suspect this bird is an escapee – as far as I can read up, it’s not common, if at all, found in Georgetown, Penang where I am. I’m also not optimistic that it can survive if I were to set it free – assuming it can sustain it’s flight and not go crashing down and if there were dogs/cats around that would be the end of it.
    I can attach some pictures but not sure how to do this…
    thanks.

    The blue-crowned hanging parrot, even though very closely related to the lovebirds, is a nectar feeder. You would raise it the way you raise a lorikeet – which is a messy process. And because you are mixing batches of food for just one little bird, whereas I used to do it for about half a dozen pigeon-sized lorikeets each morning, I don’t know how you are going to get the portions down to manageable sizes. Anyway, here goes, with my recipe for feeding big lories. You can adjust the proportions down accordingly for your little bird.

    The staple diet would be a couple of slices of soft fruit (papaya, apple, grapes, even though I am surprised that you said the bird would not eat any) and a mixture of cooked rice sweetened with nectar mix.

    How to make nectar mix? Go to a pharmacy and get a can of food for invalids or infants. I use Complan, but I am sure any good baby formula would do. I usually make up enough to fill a beer mug, but there is no way you need that amount for a day’s feeding. If in doubt, make the mixture thinner, not thicker. Birds cannot digest baby formula that is too thick. If it is too thin, they simply have to consume more to get the required amount of energy. Then to this mug, add half a teaspoonful of rose syrup. Also stir in about a cup of cooked rice, well mashed up.

    In the case of your bird, I suggest that you pour this lot into an ice-cube tray, freeze the mixture, and defrost one cube to feed it each day.

    Now, you said that this bird eats sunflower seeds. This is most unusual for a blue-crowned hanging parrot. Are you sure that this is actually the species you have? Could it be possible that you have actually got a pet lovebird that escaped? There are so many different artificially-created breeds of lovebirds in so many colours that you might have been mistaken.

    If you actually have a lovebird, feeding is much simpler. Just go to the nearest pet shop, buy a packet of budgerigar or cockatiel seed of a reputable international brand, and offer it to the bird. You can supplement this with a couple of slices of fruit each day, and that will be all. Plus of course fresh water and a piece of cuttlefish bone to nibble on.

    About nectar feeding birds. I forgot to add that feeding nectar is messy, and it goes rancid very quickly in our tropical weather. Feeding containers have to be removed and thoroughly cleaned at the end of each day. The birds also splatter the mixture and wipe their beaks on perches and the bars of the cage. All my lories and lorikeets used to be housed in outdoor aviaries which were hosed down daily.

    If Geam Liang does not think the bird will survive if released, I really hope that it is a case of mistaken identity, and that you have a lovebird, rather than a blue-crowned hanging parrot. In our part of the world, all available lovebirds are domestically bred, take to captivity readily, and are easy to feed with commercially available seed mixtures. Yes, and being domestic pets, they would not survive if released.

    Thank you Chiu San for your inputs. Thus far, bananas and papayas work well. I’m not sure why it did not take to grapes – will try again. Am I supposed to peel it? I didn’t the last time, basically skewered a couple of grapes to a satay stick and positioned it as I did for the sliced and skinned papaya and peeled bananas.
    I have yet to try rice and certainly not nectar but will try out your concoction – have half a mind to go to a pet shop to see if they carry nectar for birds. The ice-cube freeze method is a good one, will try that. I might be mistaken on the sunflower seeds… not touched but it did eat the much smaller roundish, mixed colored seeds. Will remove the sunflower seeds.
    I’m sure it’s a female blue crowned hanging parrot.. it sleeps like a bat every night.

  12. Lee Chiu San

    When feeding local birds which are unfamiliar with imported fruits such as grapes, it helps to split the fruits to expose the edible parts. As to your remark that the bird sleeps hanging upside down like a bat, yes, that is the way blue-crowned hanging parrots sleep.

  13. Geam Liang

    Thanks… I need to think like a bird – yup. She has probably not seen a grape much less know that it’s edible, unless the previous owner has fed her with grapes… even then… Today she’s done pretty well making the most of the banana and all of the papaya plus quite a bit of seeds. Will try the baby food + mashed rise + rose syrup.
    Will regular honey do instead of rose syrup?
    Thanks.

    About making nectar to feed birds. Most aviculturalists do not use honey for two reasons: 1. It is expensive and does not seem to give any added benefits. 2. Honey is made by bees, and the composition varies wildly. Some honeys are also known to cause fungal infection in birds.

    If you do not want to buy a huge bottle of rose syrup just for one tiny bird, there are cheaper alternatives. The first is plain table sugar, though most don’t seem to like it very much.

    What many birds will accept quite readily as a sweetener is condensed milk – the type with sugar that coffee shop owners use.

    Many, many birds have a sweet tooth (or should I say sweet beak?) Besides the usual suspects of lories, lorikeets, sunbirds and hummingbirds, for whom it is an essential part of the diet, nectar mixture is readily consumed by mynahs, leafbirds, fairy bluebirds, barbets, doves, parrots of all kinds, and a whole host of other species.

  15. Geam Liang

    I tried the condensed mild, placed in in a small bottle cap.. only the ants showed interest. Am I supposed to dilute it? I didn’t =( I took you advice and refrained from honey. Have yet to find Rose Syrup from the shelves of TESCO… will try to mix the baby food + mashed rise + rose syrup/sugar syrup this week…

    Can anyone help me identify a bird I saw in Singapore last week. Size of a smakll dove or thrush. Dark metallic back. Grey breast with red throat, chest.

    Lately I bought a bird feeder which I fill with 4parts water n 1 part white sugar. Sunbirds come regularly to drink and they are really lovely to watch. May I know if it is bad for them to feed on this? Previously they would sometimes pierce and drink from my potted flowers

    Dear Sir / Dear Madame,

    I am a Senior Lecturer in Zoology at a University in Switzerland and I urgently need to get in touch with photographer Chan Yoke Meng, who takes beautiful photographs of birds near Singapore. Would you please mail me the email address of this photographer!

    Thanks,
    Martin

    Hello Besgroup,

    Trust this email finds you well. We chance upon your photograph on your website and found the amazing image of the Laced Woodpecker and durians. We would like to explore the possibility of getting permission to use them for a new Bird Park in Singapore.

    Spacelogic is a company based in Singapore and we have been contracted by Mandai Park Development to carry out design and build works relating to the exhibition interpretive displays in this new Bird Park.

    Some background of the new Mandai Bird Park project; it will build upon the legacy of the Jurong Bird Park – https://www.wrs.com.sg/en/jurong-bird-park.html by retaining and building upon a world-reference bird collection and creating a place of colour and joy for all visitors. The new Bird Park will have a world-reference ornithological collection displayed in a highly immersive way with large walk-through habitats. To enhance visitors’ experience with storyline and narrative of the bird park, transition spaces are added to display exhibits that provide a varied type of fun, intuitive, interactive and educational experiences for all visitors. One of the habitats features the Laced Woodpecker on a flora panel It is in this flora panel that we are seeking your permission to feature the Laced Woodpecker. We are looking to use the first image on the link here.
    Link can be found here: https://besgroup.org/2012/06/28/laced-woodpecker-and-durians/

    We would like to ask if this is something that we can explore further and if yes, how can we go about with putting through a formal permission request. Thank you so much for considering our request and we look forward to hearing from you.

    Warmest Regards,
    Wee Ming
    SPACElogic Pte Ltd
