Fork-tailed Sunbird and Orange-bellied Leafbird on Coral Tree Flowers, Tai Po Kau (Birding Hong Kong archive)
The 2018/19 winter (December to February) was the warmest on record. The first few days of March proved to be more typical for the time of year, being grey and miserable. A trough of low pressure brought rain, sometimes heavy, to the territory. Temperatures ranged from 15-21⁰C for most of the period.
The highlight of early March was Mrs Gould’s Sunbird. An immature male was at KFBG on 4th and a much-photographed adult male was at Tai Po Kau from 4th until at least 8th. See http://www.hkbws.org.hk/BBS/viewthread.php?tid=28026 .
The Avifauna of Hong Kong reported three records of this very colourful sunbird (1988, 1990 and 1998) but these were considered to be ex-captive birds. The first accepted record of a wild bird was a male at Tai Po Kau from 22nd to 30th January 2005. There were eleven further records of the species between 2006 and 2018, all in the period 15 January to 6 April, which coincides with the flowering season of Coral Trees Erythrina spp. in Hong Kong. The most birds present at a single location were two males and a female at KFBG from 24 February to 27 March 2014.
Four races of Mrs Gould’s Sunbird occur in the Oriental region, two of them in China. The one that occurs in Hong Kong is Aethopyga gouldiae dabryii. This subspecies breeds in extreme northeast India, Myanmar, north Indochina, and in central & southwest China east to Guangxi. Some are known to winter in southern Myanmar and northern Thailand, and based on the Hong Kong records, it is evident that some birds also wander to the coastal areas of southern China.
Other birds at Tai Po Kau included Chinese Barbet, Speckled Piculet, Chestnut-crowned Warblers and two Sulphur-breasted Warblers on 2nd. The Chinese Barbet was heard on and off until at least 8th, and a White Spectacled Warbler and one of the Sulphur-breasted Warblers were reorted on 5th.
A Large Hawk Cuckoo and a Plaintive Cuckoo were heard singing in the Lam Tsuen valley on 1st. (This was, however, not the first report of Large Hawk Cuckoo in the territory; birds were heard at Shek Kong catchwater on 23rd February and at Lantau Peak on 24th February.)
Mai Po held a 1st-winter Pallas’s Gull, two Black-tailed Gulls and a Caspian Tern on 1st. On 8th, signs of shorebird movement were evinced by the presence of ten Curlew Sandpipers and six Broad-billed Sandpipers; other sightings included a Far Eastern Curlew, four Pallas’s Gulls, a Slaty-backed Gull, a Gull-billed tern and three Caspian Terns. On 9th, a Long- billed Dowitcher, three Black-tailed Gulls and two Pallas’s Gulls were noted, and a Lanceolated Warbler was singing along the access road.
An Arctic Warbler was again heard calling at Ho Man Tin on 2nd and the wintering Yellow-streaked Warbler was seen at Mt Davis on the same date. The wintering Smew was also seen at San Tin on 2nd.
The HK Wetland Park had a Long-billed Dowitcher on 3rd. An Eastern Water Rail was at Long Valley on 8th.

March 11-17
Fine and dry at the beginning and end of the week, but fresh easterlies/northeasterlies from 13th to 15th brought cooler temperatures and rain to the territory.

March 18-24
The weather during the week was dominated by a warm and humid maritime airstream from the southeast with temperatures in the New Territories up to 28⁰C. This changed on the evening of the 22nd when a cold front swept in from the northeast bringing cloud, rain and cooler temperatures.
The main event of the week was the arrival of two Glossy Ibis at Mai Po on 20th. The birds were seen only briefly before they disappeared; fortunately they were rediscovered at Long Valley on 21st where they remained through 22nd. However, there was no sign of them on 23rd or 24th. There have only been two previous records of this species in Hong Kong – both singles and both at Mai Po - on 21 April 1978 and 1st – 2nd May 1994.
Apart from the ibis, Mai Po held 38 Great Knots, 45 Curlew Sandpipers, nine Caspian Terns and three Gull-billed Terns on 20th. Two Far Eastern Curlews, 20 Great Knots, a Red Knot, the Long-billed Dowitcher, a Pallas’s Gull, a Black-tailed Gull and two Styan’s Grasshopper Warblers were noted on 21st. Caspian Tern numbers had risen to 26 on 23rd but wader numbers remained low. Birds of interest on 24th included a Greater Spotted Eagle, two Long-billed Dowitchers, a Nordmann’s Greenshank, nine Broad-billed Sandpipers, three Red-necked Phalaropes, two Silver-backed Needletails and a Pacific Swift.
Tai Po Kau turned up Chinese Barbet, Blue-and-white Flycatcher and Verditer Flycatcher on 18th. Two Chinese Barbets were heard on 20th. On 22nd a Chinese barbet, a female Narcissus Flycatcher and a Japanese Thrush were reported – see https://ebird.org/view/checklist/S54092958 for Roman Lo’s photographs of the flycatcher and thrush.
On 19th Tai Lam CP had Crested Honey Buzzard, Black Bulbul, Verditer Flycatcher and 15 Japanese Thrushes; two Japanese Thrushes were at Sha Lo Tung on the same day.

March 25-31
Western Yellow Wagtail Motacilla flava leucocephala at Lut Chau, 28 March 2019
The weather was generally warm and humid with temperatures reaching 27⁰C on 28th. A surge of the northeast monsoon on the last two days of the month brought fresh easterly winds and slightly cooler weather to the territory.
Bird-wise, the week was of great interest with a good number of migrants around and a potential first record of Western Yellow Wagtail and a possible second record of Zappey’s Flycatcher, although neither bird is proving uncontentious when it comes to identification.

Zappey's Flycatcher (?) at the Peak, 29th March 2019 - photographs © Richard White
Zappey’s Flycatcher: a blue-and-white flycatcher photographed by Richard White - a visiting birder - at the Peak on 29th (see above) was identified as a Zappey’s Flycatcher from the images - a potential second record for Hong Kong. However, those in search of the flycatcher on the following day found what was clearly a Blue-and-white Flycatcher of the race intermedia in the same tree. So, either a) two different birds were involved – a Zappey’s Flycatcher on 29th and a Blue-and-white Flycatcher intermedia on 30th, or b) something in the photographic process (exposure, angle of view, light…?) is inadvertently creating a false impression and, in some cameras at least, rendering the lores darker and more contrasting than they actually appear in the field. The first and only record of Zappey's Flycatcher in Hong Kong to date was at Po Toi on 19th October 2008. For a photo of this bird, see:

Blue-and-white Flycatcher: one of the race intermedia at the Peak on 30th; one (nominate race?) at Tai Po Kau on 31st
Narcissus Flycatcher: five at Ho Man Tin and one at Tai Po Kau on 31st
Western Yellow Wagtail: a bird showing features of the white-headed race Motacilla flava leucocephala was at Lut Chau from 28th to 31st. A first record for Hong Kong if accepted
Citrine Wagtail: one at Long Valley on 27th.
Black-headed Bunting: one at Po Toi on 30th.
