Migratory Waders - Mudflat and Fish Ponds

Other than the colourful migratory flycatchers, spring is one of the best time in Hong Kong to look for migratory waders. The top choice is to visit Deep Bay and Mai Po, as the tide comes in the waders comes with it. Thousands of these birds comes through Hong Kong each year, it takes a bit of patience to scan through them all, picking out the less common species amongst the common ones.

Common Redshanks & Curlew Sandpipers

Great Knots are now in their breeding plumage, these pretty waders used to be a lot more common but now considered an endangered species due to rapid decline. I found a few Far Eastern Curlew standing amongst the Eurasian Curlews, this is also an endangered species, fairly regularly seen in Hong Kong during migratory season.

I scanned through the smaller waders hoping for some stints on the mudflat but only got Curlew Sandpipers, many now moulting into their brick red breeding plumage. A few Greater Sand Plovers in their breeding plumage stand out from the rest of the Common Redshanks. Some Black-tailed Godwits are also moulting, soon most of them will look like this one below.

Spring is one of the best time to look for Nordmann's Greenshanks in Hong Kong, on that day I counted around 10 of these endangered birds, mixed in amongst the Common Greenshanks. They are slightly shorter and compact compared the the Common Greenshank, with shorter tibia, shorter primary projection, giving them an overall rounded look, even when they are resting you can see the difference in their structure.

Chinese Pond Herons now moulting into their pretty breeding plumage, I also saw an Intermediate Egret in breeding plumage, I don't quite recall photographing one before. Still plenty of Black-faced Spoonbills feeding on the mudflat, always nice to see them up close.

The Black-headed Gulls are opportunistic, as shown here three chasing after a Great Egret which just caught itself a nice big mudskipper. It was stolen by one of the Black-headed Gull in the end. Other than the Black-headed Gulls, Caspian and Gull-billed Terns are now in fairly good numbers on the mudflat. Quite a lot of Lesser Black-backed Gulls (heuglini) and Vega Gull (mongolicus) remains.

Back out towards the buffalo fields I spotted a Grey-headed Lapwing, this brings back memories of looking for these Lapwings on the now destroyed buffalo fields at Kam Tin, it used to be one of our favourite birding spot before it turned into a residential estate.

Mudflat out on Deep Bay is not the only place to look for migrants, drained fish ponds in area like San Tin and Tai Sang Wai can be equally productive given the right conditions! A drained pond at San Tin have been incredibly productive of late, with new waders coming in every few days. Such as Greater and Lesser Sand Plovers, Kentish Plovers and the numerous resident Little Ringed Plovers.

Long-toed Stints in their breeding plumage is always very eye-catching, they are bright orange and stand out from the dull mud. Temminck's Stints are far more reserve in their colours, often blending in so well that they are easily missed. Wood Sandpipers are fairly common in these ponds and can be quite confiding.

There were quite a few Red-necked Stints as well, whenever I see Red-necked Stints I always scan for two other species, the Spoon-billed Sandpiper and the Little Stint. While finding a Spoon-billed Sandpiper in a drained fishponds maybe a bit less likely (though it happened before), we every so often get Little Stints mixed in with the Red-necked. The Little Stint I found late last month stayed on and remained quite confiding, allowing me to get some better photos than last time.

Along the fish ponds I found a stretch of road with many Oriental Pratincole roosting, they allowed relatively close views. These are one of my favourite passage migrants, incredibly cute and full of character, they can be a lot of fun to look at.

A Sand Martin been flying around with the Barn Swallows at San Tin, I didn't really bother getting good photos, but it occasionally flew in quite close. Eastern Yellow Wagtails now very numerous, occasionally you may find a few tschutschensis mixed in the usual taivana. Whiskered Terns are now starting to arrive in their elegant breeding plumage.

Over at Tai Sang Wai, I finally got a photo of one of the Golden-headed Cisticola I've heard lately but not seen. Getting there earlier in the morning seems to have done the trick, as I found it already perched up on in the open to preen, it was in fact quite confiding. Though not the breeding plumage bird I was hoping to find, it is still a nice bird to see up close.

The best bird in my ventures around the fish ponds was a Northern Goshawk I chanced upon at San Tin. It suddenly flew out from a tree and caught me by complete surprise, it was too close to me and for my camera to react! It was flying away from me by the time my camera was able to pick up the bird on the autofocus. It was a shame I didn't get the shot I wanted, but still a thrill to see this rare raptor! Here in this photo you can just about make out the streaked breast and six 'fingers' on its right wing.

Northern Goshawk - At Long Last!

There are a few raptors that eluded my Hong Kong list for years, they are Cinereous Vulture, Mountain Hawk Eagle, Hen Harrier, Brahminy Kite and the Northern Goshawk (Cinereous Vulture being the only one here that I have never seen in my life). 2021 was an exceptional year for Northern Goshawk, and a long staying juvenile at Mai Po been seen by many. I looked for this bird many times and believe me I tried very hard, though with little success. I finally decided to spend one full day at Mai Po to try and locate this elusive raptor.

I got to Mai Po early, as its been said that the Goshawk occasionally fly past the buffalo field near the Education Centre. I stationed myself at a good vantage point and scanned the sky constantly but without success. A very friendly Long-tailed Shrike was there to keep me company. At least two Daurian Redstarts were seen along that stretch of footpath.

After a no show at the buffalo field, I moved on to the scrape. Along the way I heard the call of Taiga Flycatcher, a common winter visitor to Hong Kong. Only 10 metres further down the road was the long staying Red-breasted Flycatcher I found back in December. Though the two species look very similar, their calls are very different and should be a good clue for birders in the field. Also along the footpath were many Olive-backed Pipits.

Numerous ducks were seen on the scrape, other than the common species, up to 14 Falcated Ducks were seen, with no less than five males. The long staying Common Shelduck was still around and obviously doing quite well. Both Greater Spotted and Imperial Eagles were seen flying past the scrape, only the Greater Spotted Eagle flew close enough for a record shot.

After having no luck on the scrape, I headed over to pond 8b along the border fence where the Northern Goshawk's been frequently seen as well. After over two hours I only managed a juvenile Peregrine Falcon. This was also where four Gadwalls were found, a less common wintering duck species in Hong Kong.

One of the better bird along the fence was a single Eurasian Wryneck, this one was not particularly shy and showed very well before disappearing behind the fence. I scanned for other crows near pond 22 but only found Collared Crows present.

At around 4pm, I was on the brink of giving up. I decided to head back towards the buffalo fields to wait around. As I walked past blind no.2, I noticed a large bird hopped on a distant tree, in a manner almost Koel like. I looked through my bins and what do you know! A juvenile Northern Goshawk perched on that tree! It was perched behind several twigs and branch, but it was very clear what it was. After a few minutes it flew out from the tree towards the fence and out of sight.

Other than the Northern Goshawk, theres been a few other good birds around. One of them being a male Bull-headed Shrike in some farmland near Fanling. I see females more often, so it was nice to have a male for a change.

I haven't been to Shek Kong Catchment for a while, although it produced some good birds in the past, this site was slightly disappointing this winter, producing mainly common wintering and local species. Speckled Piculet is now a staple forest species in Hong Kong, you will find at least one among bird waves more often than you don't. Indochinese Yuhinas were in good numbers there, with at least three to four different flocks. A flowering Rhodoleia attracted Fork-tailed Sunbirds to visit. Up to two Asian Brown Flycatchers were also seen along the catchment.

I went past Tseung Kwan O the other day and spent a little time looking for Blue Rock Thrush along the sea wall, and sure enough I found a friendly female along there, although the male was nowhere to be seen. Also present was a Pacific Reef Egret.

Its been a rather disappointing winter at Brides Pool so far, I tried my luck again hoping that things may have improved over the last month. Although there were still relatively little wintering birds around, I managed to locate a Swinhoe's Minivet in amongst the Grey-chinned and Scarlet Minivets! A complete surprise for me, as this is only the 2nd winter record in Hong Kong.
