Velvet Scoter - a Hong Kong 'Proper' 1st

News of a Velvet Scoter came on Sunday, Tom Li got news out that he found it during water bird count at Tsim Bei Tsui, this was exciting news as there's not been a 'Velvet' type Scoter in Hong Kong since the species was split into three! Therefore any Scoter would have been exciting. The most logical species to occur in Hong Kong is Stejneger's Scoter, which winter along the coast of China. Photos soon surfaced and it was surely a proper Velvet! With its concave nose and yellowish orange upper mandible pattern that fits Velvet perfectly. Since I was busy working on Sunday, I was only able to go look for the bird on Monday, and luckily the bird stayed long enough for us, it was found swimming with seven Tufted Ducks, views were extremely far, my 500mm lens with 2x extender were registering the bird simply as a small dot in the distance, however through the scope I was able to pick-out all the diagnostic features, making this a Hong Kong tick plus a lifer for me! And the first truly mega rarity this spring! Below is my photo and a photo taken by Kenneth the day before, the bird was seen at a much closer range and you can see all the key features.

More waders are now coming through Deep Bay, most note worthy addition to previously seen migrant were at least two Asian Dowitchers. I scanned through the Common Greenshanks on the scrape and only found one Nordmann's Greenshank. There were still plenty of Black-faced Spoonbills around, I can never get bored of seeing them in their glorious breeding plumage. A single female Oriental Plover was all that remained, this one was seen resting on the buffalo field.

Two of the more interesting sighting at Mai Po was perhaps a Speckled Piculet near the visitor centre, a first for me here, although evidently some other birders have heard or seen them in the mangroves, not exactly the habitat we expect to find them in, however it does show how adaptable these small woodpeckers are. Two Japanese Yellow Buntings have been seen along the access footpath, almost exactly the same spot that I saw a few there couple of years back. I connected with one briefly, although it was quite shy and stayed high up in the tree the whole time.

At San Tin, I found a pair of Greater Painted Snipe frequenting one of the gully recently, a species I always enjoy seeing no matter how many times I've seen them.

The drained pond at San Tin provided plenty of good habitats for waders, especially migrants such as Red-necked Stints, many of them already moulted into their breeding plumage.




Red-necked Stint

Numerous Long-toed Stints were also feeding on this pond, these small waders are perhaps one of the most brightly coloured and pretty species. Their bigger 'cousin', the Sharp-tailed Sandpiper was also present, with three of them feeding alongside the stints.

The best of the bunch was a single Little Stint found mixed in with the Red-necked Stints, other than the smaller size, the slightly longer tibia, the bright edged tertiaries and paler throat were all good field marks to nail this one.

As temperature rises, insects are becoming more active, several good butterfly species I encountered lately, including my local Spotted Sawtooth, of which I had three together one day after the rain, this species is rare and local in Hong Kong, I am very fortunate to live in an area that get them on a regular basis.

Elsewhere, while out birding with Kenneth and James we had an Angled Sunbeam, a species I have not seen in a while, and never had a photo of it with its wings opened. Although it was outshone by a single Lesser Gull, a rare species in Hong Kong, only first recorded in 2021, a species that is likely spreading.

Rain and More Spring Migrants

April is easily one of the best time for birds in Hong Kong, and with a bit more rain in the past week or so there's definitely been an improvement in the quality of birds we are getting. I visited Ho Man Tin briefly one morning and got several key migrant flycatchers, including a couple of Narcissus Flycatchers and a very nice male Blue-and-White Flycatcher! A male Daurian Redstart was nice as this species is a lot less common comes April. A female Black-naped Monarch was a nice addition at this site.

Tai Po Kau on the other hand is not so great for migrants, but it is our best site for local forest species. Even common species are interesting, such as this Japanese Tit gathering nesting material, and a pair of Blue Whistling evidently nesting near the dam. Rufous-capped Babblers are always fun to see up close, as these curious little birds will come over if you imitate their call with whistles.

Several local species are easiest to find during spring, Chinese Barbets are now calling non-stop, although seeing them still require a bit of luck. Plain Flowerpeckers are now in song, and is the best time to see our smallest bird. White-rumped Shamas are also singing now, they certainly seem to be a fairly regular bird now at Tai Po Kau. Bay Woodpeckers are always a joy to see, especially when seen well, such as this lovely female that perched out in the open briefly!

Ma Tso Lung had been quite productive, I enjoyed several good birds there lately, including a nice looking male Bluethroat, although it didn't stay long enough for me to get a photo. A cooperative Pied Kingfisher and the long staying Little Buntings were more than happy to pose for me. I had a good counts of Grey-faced Buzzards there plus a nice looking Black-winged Kite which perched briefly for me to get some record shot.

Fish ponds around Mai Po are some of the best birding spots in Hong Kong, mainly San Tin and Tai Sang Wai, San Tin especially had been quite productive lately, with a very nice looking but rather skittish Chestnut-eared Bunting. Numerous Red Collared Doves can be found here at the moment, with over 20 on the same wire at one point.

Common Snipe is a relatively common sight here, often found quietly sitting by the edge of fish ponds, while Black-winged Stilts are almost a permanent fixture here, some evidently is attempting to breed in the area, here is a nice looking adult with a black mask. Several Oriental Pratincoles were seen on the dried pond, a species we kind of expect to find at this kind of habitats during this time of the year. One of the best local bird for me there were a pair of Greater Painted Snipes, a species not easy to find outside of Long Valley. Temminck's Stints are also relatively common here, and you can often get quite close to them with the aid of the 'car hide'.

Chinese Penduline Tits can be found here with relative ease, although I've observed that they prefer less windy days to perch up to the top of the reeds. Sand Martins are passing through in relatively good numbers at the moment, several were seen perched during a wet morning. While the long staying Pied Harrier seems to have finally departed, I found an Eastern Marsh Harrier at its usual spot.

An interesting observation was a female Ferruginous Duck on a fish pond towards Tam Kon Chau Road, around the same area there were lots of Little Grebes, many of them have started to breed, with a few pairs already rearing chicks. Tai Sang Wai on the other hand had been a bit disappointing of late, a relatively close Osprey was about the only worth noting bird there.

The best bird in the area was certainly a Ruff at San Tin! Ruff is by no means a common species in Hong Kong, and seems to be getting increasingly rarer in recent years. So, I was very pleased to see this one. Judging by the plumage I think this is an adult female.

Mai Po is of course an important stopover for many waders, many of our spring migrants are now showing well both on the scrape during high tide or out on the mudflat, many interesting species including Nordmann's Greenshank and Far Eastern Curlews can be found with relative ease, although those I saw were too far away to photograph. Amongst the many waders I found at least one Tibetan Sand Plover, the recently split species from Lesser Sand Plover, while I probably won't be able make a call on immature birds, breeding plumage birds seems straight forward enough with lack of white forehead. 


Assorted Waders...

Other notable spring migrants at Mai Po includes nearly 40 Oriental Pratincoles on the scrape, although these were outshined by just two Oriental Plovers found on one of the dried scrape. A few Ashy Minivets were seen near the larger trees at the entrance.

Definitely a lot more happening now, hopefully we will get a rarity or two in the coming few weeks.
