Solid First Week of 2021

The first week of 2021 started quite well with good birding near home, personal favourite being over twenty Common Rosefinches at Wu Kau Tang! I usually see them at Shek Kong Airfield, to see them somewhere quite close to home was extra special, especially when it was such a decent sized flock! There were far fewer males in the group, but those that were present were quite good looking.

A pair of Eurasian Jays were reported at Wu Kau Tang on the 1st, but I failed to relocate them on two visits, I was however rewarded with both a young male and an adult male Mugimaki Flycatcher. Although the adult male didn't show well, it was still a very good looking bird to encounter.

Along the footpath were a few fruiting trees, which attracted decent numbers of thrushes, mainly Eyebrowed and Japanese Thrushes, but a few Grey-backed Thrushes were also seen.

At Bride's Pool a single Indochinese Green Magpie showed exceptionally well, I have gotten so used to seeing these stunning birds in the area, where I daresay I actually see them more often now than Red-billed Blue Magpies! They are still incredibly beautiful to look at and I still marvel at their out of worldly plumage every single time.

As flowering trees are about to bloom, Orange-bellied Leafbirds become much more active, a pair showed well at Bride's Pool, mimicking a wide range of bird calls including Besra, Blue Whistling Thrush, Grey-chinned Minivet, Japanese Tit, Fork-tailed Sunbird, Ashy Drongo...the list goes on and on! The best bird at Bride's Pool was however a single Chestnut-flanked White-eye within a large flock of Swinhoe's White-eyes, it showed briefly before disappearing for rest of the morning.

At Tai Mei Tuk Catchwater, the pair of Grey Bushchats stuck around through the new year and were still present at the exact same spot. While the pair of White-bellied Sea Eagles finally paired up, now seen at their nest daily. I am also observing pairing of Black Kites in the area. The best bird at this site was no doubt an Alstrom's Warbler found by Roman on the 4th, but I was not able to relocate the bird.

Tai Po Kau continues to be very productive, with a good cast of more common woodland species showing extremely well in the large bird wave. Here is a collection of some of the most photogenic species on my visit. Grey-headed Canary Flycatchers continues to be very prominent within the bird wave.

We have unusually high numbers of Hartert's Leaf Warblers this winter, and they were in no short supply within the bird wave, and many of which showed very well. Usually I will be lucky to get just one good photo of this species on any given day, but I got plenty of good looks and good photos on just one morning! Individuals of race fokiensis were present but in fewer numbers than before.

There were at least two Sulphur-breasted Warblers still present, none of them came close for a photo, but their dark lateral crown stripes and yellow underside were always very eye-catching amongst the other warblers.

I saw at least two Kloss's within the bird wave, although there could have been more. Having seen them quite a few times now I have gotten a lot better at picking them out within the flock, they are much shorter than Hartert's with overall shorter tail, giving them an almost Pallas's Leaf Warbler jizz, they are very pale on the underside with faint yellowish tint on the vent. They are often vocal and you can hear their calls within the bird wave quite easily. I have found the undertail pattern to be tricky to nail, and it doesn't always show up on every angle, but if you get a good look it can be a good indicator in helping with the identification of this species.

The star bird at Tai Po Kau remains to be the long staying Alstrom's Warbler, it proves to be very elusive and after a few visits I have only seen the bird twice, but it is always very rewarding to see them well. I got much better photos this time round.

Tai Po Kau Warbler Mania - Alstrom's Warbler & More

Tai Po Kau had been quite productive of late, with a good range of warblers on offer, the most notable being an Alstrom's Warbler, a species I have missed several times. On my second try at Tai Po Kau I finally connected with this bird, it was a ringed individual, ringed by HKBWS on 12th of November. It was actively calling, making its presense known. Seicercus warblers are notoriously difficult to ID, key features of Alstrom's includes less prominent crown pattern, complete eye-ring and no wing bars.

Other Phylloscopus warblers present includes numerous Yellow-browed, Pallas's, Two-barred and Eastern Crowned. At least two Sulphur-breasted Warblers were seen amongst the large bird wave, their completely yellow underparts can be mistaken for a Seicercus warbler at first glance. There were plenty of Hartert's Warblers, including many of race fokiensis with pale underparts.

Other interesting birds present in the bird waves includes a female Verditer Flycatcher, this one was particularly confiding. Grey-headed Canary Flycatchers were in no short supply, there were often more than one in each bird wave. Black-winged Cuckooshrikes were also very noticable, as they are usually the biggest bird moving in the flock.

I also tried my luck at Brides Pool one morning, and was fairly productive. I scanned the numerous Swinhoe's White-eyes hoping to get a Chestnut-flanked White-eye but with little luck. The resident Velvet-fronted Nuthatches were very photogenic, while Chestnut Bulbuls came down quite low to feed.

I spotted a strange bird within the bird wave, turns out it was a Rufous-tailed Robin, it was strange to see this usually solitary ground dwelling bird following the bird waves in the trees. An Amur Paradise Flycatcher was a delightful surprise, as they are quite rare during winter months. Speckled Piculets were showing particularly well and came down to eyelevels.

I spotted an interesting leaf warbler within the bird wave, it was obviously a Hartert's type that was not particularly pale on the underside, usually I would label this as a Goodson's and move on, but it did not 'nuthatch' like they usually do...Hartert's Leaf Warblers are well known for their nuthatch like behaviour, it is a trademark that I have observed time and time again, so this unusual behaviour baffled me. At that time other similar looking warblers went through my head...Kloss's, Claudia's, Emei etc...





Hartert's Leaf Warbler

After observing it for prolonged period of time, nothing other than behaviour was suggesting otherwise, plus the undertail pattern looked to be fairly typical of Hartert's. It wasn't a particularly vocal individual, I managed to pretty terrible recording, and after asking around it was most likely just a Hartert's Leaf Warbler just as I initially thought. The question is, why did this one behaved differently? I guess we will never really know, but it does show in warbler ID you can't often determine the true identity of a warbler with one single factor, it is usually combined factors that will lead you to the correct identification.

At Tai Mei Tuk Catchwater, not a huge amount of new birds were seen, I finally connected with a long staying male Black-naped Oriole, it was being quite elusive and didn't make it easy for photographs. It was seen following the large flock of Scarlet Minivets, where it blends in well with the female Minivets, although its bigger size does give it away. It was quite the stunner and probably the best looking Black-naped Oriole I have seen in Hong Kong for years. The Grey Bush Chats were still present, often show well if you give it a little time.
