Manchurian Reed Warblers & More

Manchurian Reed Warbler - top bird so far this autumn

Migrants continues to roll in through early October, with a few more interesting birds seen at various places. Long Valley had been a little bit on the quieter side at the moment, or at least for me. Other than the few "Swin-tailed" Snipes and Greater Painted Snipes which I flushed, more stationary birds included a few confiding Common Snipes and a single Red-necked Phalarope which had been here since the typhoon.

Zitting Cisticolas are now quite numerous, I flushed up to six birds in one patch of tall grass. While pipits numbers were still slightly under my expectation, with juts a handful of Richard's Pipits and Red-throated Pipits. The lack of any buntings on my last visit was slightly alarming...hopefully a few will return very soon!

San Tin on the other hand had been fairly productive, this includes some of the highest counts of Red-collared Doves I've seen in years, up to fifty plus birds. A few of which provided good views from the comfort of the car...

The drainage ditch just outside the fishpond area had also been busy with birds, mostly Black-winged Stilts, but also a good range of waders, including Wood Sandpipers, Green Sandpipers, Common Snipes and Common Greenshanks. There's also been a few Eurasian Teals around.

Inside the fishponds area, the long staying Common Pochard had been showing on and off, it can be tricky to pin down on somedays, moving from pond to pond. I saw it at a distance the other day against the light, I wanted to move to the other side of the pond to get some better photos, only that the bird managed to vanished without me noticing...

Yellow Bitterns had also been seen, although not providing the best of views...while a pair of Whiskered Tern; an adult and a juvenile had stayed on, I caught them resting on a wire the other day, rather than circling the fishponds as they often do.

A single Little Bunting at San Tin was not exactly an exciting find, but after a long absent during the summer months it is a welcoming sight to behold, it's also a nice thought that we will probably get to see these lovely birds quite often in the upcoming few months. This particular bird perched next to the road allowed me to get a very close look, the car worked perfectly as a bird hide.

I visited Mai Po for the first time since the typhoon this week. The typhoon left a few marks in the reserve, including a few broken bird hides, fallen trees and broken footpaths, but otherwise it was business as usual. Things started off fairly slowly for me, with a few confiding Asian Brown Flycatchers. I also spotted a female Black-naped Monarch but couldn't manage a photo.

Purple Herons are always nice to see, this species have a fairly restricted distribution in Hong Kong, with most records around Deep Bay area. Mai Po is likely the easiest place to find them.

I was a little late for the tide, but most of the waders roosted at pond 16/17 during the high tide. Black-tailed Godwits were amongst some of the most numerous. Although there were a few Bar-tailed Godwits around. Other waders present were Common Greenshanks, Marsh Sandpipers, Common Redshanks, Eurasian Curlews, Whimbrels, Dunlins and Kentish Plovers.

A few Eurasian Wigeons were also present, they are probably quite recent arrivals. Here is a photo of an eclipse male and a female. I also spotted a single Cinnamon Bittern which flew past the bird hide but was too quick for me to grab a shot.


Eurasian Wigeon

I flushed a Lanceolated Warbler from the side of the footpath, they are notoriously difficult to see well, but this one perched still enough for me to grab a record shot.

Along the access footpath past the AFCD warden's post, I noticed a few Buntings feeding on the ground on the opposite side of the channel, they were flushed and flew up to the trees next to the footpath. A closer look confirmed them to be Yellow-browed Buntings, a fairly uncommon species in Hong Kong.



Yellow-browed Bunting - a very pleasant surprise!

Although the top bird at Mai Po was no doubt the Manchurian Reed Warbler found by David Diskin. This vulnerable species is a rare passage migrant in Hong Kong, where they breed around Heilongjiang and Russia, wintering in Cambodia and Thailand. As with all reed warblers they can be tricky to see, but this individual was more than happy enough to feed out in the open, allowing very decent views.




Manchurian Reed Warbler - putting on first class performance!

They look superficially similar to the far more common Black-browed Reed Warblers, but a side by side comparison reveals quite a different looking brow arrangement, where the Black-browed Reed Warbler have a much thicker and stronger black brow above it's supercilium, Manchurian Reed Warbler's eyebrow is much weaker. They also have a more uniformly coloured tail, where Black-browed Reed Warblers show a darker tail with pale edge.

I've continued with a bit of herping here and there, was very pleased to found a few Chinese Water Dragons near home, although they are said to be an introduced species in Hong Kong, they are impressive looking reptiles. They have been breeding in Hong Kong for some years now, whether they have an impact on the local ecosystem is unknown, but they are certainly interesting to look at.

While at Tai Mo Shan, I was rewarded with a few interesting species by searching along streams, including a very cooperative Chinese Waterside Skink. A young Chinese Bullfrog was likely part of a religious released population, although it looked pretty healthy. A few Giant Spiny Frogs were a great sight to behold as always, they are very impressive when seen up close and you understand why they are called 'giants'...

Finally, while waiting for Hoiling to finish her class one evening last week, I strolled around Lung Fu Shan and came across yet another Bamboo Pit Viper. This one was not particularly friendly, and me removing it from the footpath probably provoked it even more...After placing it on a branch nearby I took a few photos and left it in peace.

Mid-Autumn Bird & Herps

Red-necked Phalarope - a good 'performance' at Long Valley

Mid-Autumn festival just past, and by the end of September bird migration is in full swing. At Ho Man Tin, other than the ever present Asian Brown Flycatchers, there was also a Dark-sided Flycatcher around. While a pair of Hainan Blue Flycatchers had also decided to make a stop here, which seems to have attracted a good numbers of photographers.

Since Pale-legged Leaf Warblers and Sakhalin Leaf Warblers had been split recently, identifying these warblers correctly have became a challenge for birders, with no decent visible key identification features, you really need to hear listen for the subtle differences in their calls to be able to confirm your ID. Those birds I heard (if they did call) at Ho Man Tin were definitely Pale-legged Leaf Warblers, sounding much higher pitched (5700hz). Back at my local patch I heard a Sakhalin Leaf Warbler, it sounded much lower pitched (4700hz). So, it is possible to separate them if you are lucky enough to hear them calling nearby. This bird below was one of the many Pale-legged Leaf Warblers
at Ho Man Tin.

Another species that had been active around Ho Man Tin were at least two Orange-headed Thrush, a male and female. They were pretty easy to see, but not always easy to photograph. I got lucky the other day when the male decided to perch very still for up to five minutes, it looked like it was dozing off. I saw the female very well but wasn't able to get a clear shot.

Orange-headed Thrush - a true stunner of a bird

A juvenile Asian Koel was seen begging for food from it's foster parents...A pair of Red-billed Blue Magpies. They are also known to parasitise Black-collared Starlings and Eurasian Magpies.

Brown Shrikes had also became a regular staple at Ho Man Tin, with up to three different individuals, one of which posed nicely for me the other day. While the long staying Tiger Shrike had remained elusive for quite a number of birders, I was fortunate enough to caught a glimpse of it again the other day, it only showed briefly but that was more than enough for me!

I visited Long Valley last Sunday afternoon, it was slightly on the quiet side, but a group of up to five extremely confiding Red-necked Phalaropes provided plenty of fun. These migratory waders usually winters in tropical oceans after breeding in the arctic tundra, but they can often be found in marshes or even urban parks during passage.

To give you an idea how close they can get, here is a photo taken with my phone of two that trotted past just 2m in front of me, too close for my 500mm lens...And I got what was probably my rarest finding of the day; Mr. John Holmes, who joined in the 'phalaropes mania', he also kindly demonstrated the proper way to take photos of these friendly little birds.

It was pretty quiet around Long Valley, with no Buntings in sight. The only two species worth mentioning were a single Eurasian Teal and a Plaintive Cuckoo. I also spotted four Red Collared Doves which flew overhead.

Autumn is not only great for birds, but it is also a good time for herping, snakes are often quite active before their hibernation and frogs can be located easier in damper areas during these drier periods. We visited Shek Kong Catchment the other night, starting off the night with a tiny White-spotted Slug Snake, a docile species that is always fun to find.

We saw up to five Bamboo Pit Vipers throughout the evening, although a common species in Hong Kong I never get tired seeing them. They are extremely well camouflaged during the day, but at night their brightly coloured yellow belly is often quite visible amongst vegetation.

There were plenty of common frog species, but we also found a few nicer and slightly less seen species, including the cute Spotted Narrow-mouthed Frog. A few Ornate Pygmy Frogs were spotted in an area of damp grass. Mixed in with them were a few Butler's Pygmy Frogs, a species that is uncommon in Hong Kong.

Finally, some 'night birds'...A pair of sleeping Common Tailorbirds, they can often be found sleeping near the end of branches, sometimes at distances you can simply reach with your hands.
