There is a Martens's Warbler Seicercus omeiensis at Pak Sha O, which is an enclave within Sai Kung West Country Park. Access to the village is via a footpath from Hoi Ha Road, about 1.5km before Hoi Ha Village. The bird is on winter territory in the area along the footpath between lamp post numbers VA5393 and VA5394, on the left as you go down to the village. If accepted, this would be the first for HK.

The call is diagnostic among Seicercus, and a recording is below.

The photo below is useful in that it confirms the orbital ring is complete around the eye.



There is no private car access to Hoi Ha Road without a permit. Minibus no. 7 runs from Sai Kung Pier to Hoi Ha, at around half-hourly intervals from approx. 8am to 6pm. It is rather more frequent at the weekend, but the schedule is rather erratic.

Ah Ah, that's a good one... well done Geoff.

Geoff, is Seicercus omeiensis more likely to  winter in HK than Seicercus valentini? The Golden-spectacled Warbler I observed Friday could very well have been Seicercus omeiensis in that the eyering was complete, there was no visible wingbar, and the white on the outer rectrices appears to extend all the way to the base. I didn't consider that possibility at the time. I will try to relocate it and try to hear the call.

Too few records to say, Brendan. Valentini breeds quite close to HK in northern Guangdong, while omeiensis has been recorded on Hainan.

In terms of plumage, the two are very similar. Valentini tends to have a slightly more distinct wing bar, I think. Call remains the easiest way to separate this group outside the breeding season.

I should perhaps say that this bird has been very elusive, and may require some time to see. It has showed throughout the day though.

I found this year a population of Martens's warbler in NW Hunan that is as far as I know the closiest one to HK.

Geoff,
Would you mind attaching a map here?
I'm not sure about your exact location mentioned above.

Thanks,

On the image below, I've marked the entrance to the path down to Pak Sha O. This is just past PSO Youth Hostel. The path runs alongside the youth hostel, and a short distance beyond, between the lamp posts mentioned above, is area in which I've seen the bird.

The bird was still present today though it took 4 hours to find and was very mobile

Geoff thanks for the info and detailed directions.

Thanks Geoff again.
The warbler showed up and started calling at 10:50 and it is really hard to take a good shot.

Also a nice birding day in Pak Sha O today.  It was more birdy that I expected and lucky to tick the potential HK first.

Pak Sha O contains quite a few different terrains.  There are some pieces of relatively small scale of open flatland, a cultivated area (that I just recognized today), shrubs and also woodland areas.

Cheers

Here is a very useful reference written by Per Alström for ID Golden-spectacled Warblers.

I saw the bird again today (Friday 25th) at around 5pm, lower down, near the toilet. Gave good, but brief view.

no Martens' but five thrush species today
Japanese Thrush 1x (F)
Grey-backed Thrush 3+ (2F+1M)
Scaly Thrush 1x
Chinese Blackbird 2+
Blue Whistling Thrush 1
Greater necklaced Laughingthrush a party
Red-flanked Bluetail 1 (F)
Rufous-tailed Robin 1
Asian Stubtail Warbler 1
Daurian Redstart 2 (1F+1M)
Blue-winged Minla and other common forest birds

Sad to see the damage done to the swamps near the village of Pak Tam O, all due to developers, who want to change the old style houses in "new modern crap". When is Hong Kong going to realise the wealth of its national heritage and biodiversity.

If you are concerned about Pak Sha O and want to urge the government to protect the biodiversity and cultural heritage of the area, you can provide your views to government, as this is the consultation period for the draft Development Permission Area plan that was issued in response to indications that applications for development in this enclave within the Country Park might be made in the near future. Send an email to The Secretary, Town Planning Board at tpbpd@pland.gov.hk with the title: Draft Pak Sha O Development Permission Area Plan DPA/NE-PSO/1. Remember to provide your HKID or passport number. The closing date for submissions is 7th February (this coming Thursday). The more submissions, the more likely the TPB will heed calls for restricting development possibilities.

For those interested, I saw this bird again today, after a gap of 3 weeks. Same place. Calling vigorously around mid morning.
