Grey-streaked Flycatcher on spring migration (Birding Hong Kong archive)
May began with unsettled weather. Temperatures did not rise above 28⁰C, and for the most part it was refreshingly cool and cloudy. Rain showers were sometimes heavy and winds were fresh easterlies. Such weather conditions in spring can be good for migrants and early May did not disappoint.
 
At Tai Lam Country Park on  1st, a Chinese Sparrowhawk, six Hodgson’s Hawk Cuckoos, a late Black-winged Cuckooshrike, six Black Bulbuls, 13 Lesser Shortwings, 43 Eyebrowed Thrushes and a  Grey-streaked Flycatcher were counted. In the same general area, a Rufous-tailed Robin was singing at Ho Pui reservoir, two Chinese Sparrowhawks, an Oriental Dollarbird and  two Grey-streaked Flycatchers were at Shek Kong catchwater and another Chinese Sparrowhawk was at Shek Kong Airfield Road.
 
Tai Lam Country Park turned up 170 Eyebrowed Thrushes – a record count - on 3rd, along with an Orange-headed Thrush and the Black-winged Cuckooshrike. A further 165 Eyebrowed Thrushes were seen there on 4th. Nine Hodgson’s Hawk Cuckoo were counted there on the same day – another new high count, the highest previous count being five, also at Tai Lam Country Park,  on 1 May 2017.
 
Birds at Shek Kong catchwater on 4th included  a Grey-faced Buzzard, six Silver-backed Needletails (plus 40 distant needletails sp.), five Chinese Sparrowhawks, an Oriental Dollarbird, an Ashy Minivet, a Japanese Paradise Flycatcher, six Grey-streaked Flycatchers and a Rufous-tailed Robin. On 5th, nine Grey-streaked Flycatchers and eight Oriental  Dollarbirds were counted there.
 
The Collared Owlet, a Chinese Barbet and four Plain Flowerpeckers were at Tai Po Kau on 1st.
 
At Ho Man Tin the male Siberian Thrush remained until at least 4th. Other birds there included a female Narcissus Flycatcher on 1st, single Asian Brown and Grey-streaked Flycatchers,  a Radde’s Warbler, an Arctic Warbler, two Pale-legged Leaf Warblers and three Brown Shrikes on 3rd, and a Pale-legged Leaf Warbler and  two Arctic Warblers on 4th.
 
Two Oriental Dollarbirds and a Grey-streaked Flycatcher were at Sha Lo Tung on 2nd, and a Pechora Pipit was at Tai Sang Wai on the same day.
 
On 2nd, Po Toi turned up 50 Bridled Terns, ten Black-naped Terns, two Chinese Sparrowhawks, a Brown Shrike, three Grey-streaked Flycatchers and two Asian Brown Flycatchers. The island proved productive on 4th, when migrants included a Malayan Night Heron, five Chinese Sparrowhawks, two Oriental Dollarbirds, an Oriental Cuckoo, a Swinhoe’s Minivet, 60 Brown Shrikes, five Arctic Warblers, an Eyebrowed Thrush, eight Grey-streaked Flycatchers, a Ferruginous Flycatcher and eight Black-faced Buntings. The Ferruginous Flycatcher was a new latest record by two days.
 
On 3rd, 30 Asian Dowitchers, two Nordmann’s Greenshanks, a Himalayan Swiftlet, four Blue-tailed Bee-eaters,  60 Sand Martins, a Styan’s Grasshopper Warbler and  two Yellow-breasted Buntings were at Mai Po. Birds seen on the reserve on 4th included a Cinnamon Bittern, 85 Asian Dowitchers, a Nordmann’s Greenshank, six Blue-tailed Bee-eaters and 70 Sand Martins. A Pheasant-tailed Jacana and a Himalayan Swiftlet were present on 5th.
 
Elsewhere on 3rd, an Ashy Drongo and a  Brown Shrike were in Kowloon Park, and a Cinnamon Bittern and a Pheasant-tailed Jacana were at Long Valley. Reports at Long Valley on 5th included a Pheasant-tailed Jacana, a Pechora Pipit and nine Yellow-breasted Buntings.
 
On 4th, in addition to the records already cited, a Forest Wagtail was on Lamma, two Yellow-breasted Buntings were at Cheung Po, and three Chinese Sparrowhawks, two Oriental Dollarbirds and a Grey-streaked Flycatcher were at Lam Tsuen.
 
Three Arctic Warblers and four Grey-streaked Flycatchers were at Tai Tong on 5th. 

May 6-12

             Grey-faced Buzzard on Po Toi, 11 May 2019
Unfortunately this bird was in a poor condition - presumably from exhaustion - and apparently died later in the day.
The unsettled weather continued until the afternoon of 9th, after which conditions improved quickly, the clouds thinned and the temperature rose. Migrant  bitterns  were in evidence and good numbers of typical late spring migrants – Brown Shrikes, Arctic Warblers and Grey-streaked Flycatchers – were widespread. In addition, there were number of sightings of migrants reported on dates later than the previous “latest date” records; these are detailed below. (It should be noted that such records – as with any rare or unusual sightings - may be subject to assessment by the HKBWS Records Committee.)
 
The hazards of  migration were sadly exemplified at Po Toi on 11 May when a sick and exhausted Grey-faced Buzzard, as well as a Yellow Bittern, apparently died within a short period of being discovered.

May 13-19      
Hot and sunny with the odd shower and winds mainly from the southwest. In the New Territories, the temperature reached 33⁰C on 18th & 19th.
 
In terms of bird watching, the fine weather seemed to mark the beginning of the summer doldrums in terms of bird watching in Hong Kong, although there was still  a trickle of migrants going through.
 
On 13th, Tai Lam Country Park turned up a Lesser Cuckoo, a Brown-breasted Flycatcher,  five Grey-streaked Flycatchers and five Black Bulbuls. Also on 13th, a Chinese Sparrowhawk and an Oriental Dollarbird were at Ho Chung, and an Arctic Warbler was on Cheung Chau.
 
At Mai Po, a Von Schrenck’s Bittern was seen on 13th and a Black Bittern flew across the access road on 17th.
 
At Long Valley, a Baillon’s Crake and a Pheasant-tailed Jacana were present on 13th; the Pheasant-tailed Jacana was seen again on 14th and the Baillon’s Crake was again noted on 17th.
 
Po Toi held four Yellow Bitterns, a Chinese Sparrowhawk, an Arctic Warbler and  two Grey-streaked Flycatchers on 14th. Also on 14th, a Lesser Cuckoo was heard in Tai Po Kau.
 
A latish Dusky Warbler was at Ho Man Tin on 16th.
 
A late Tufted Duck, a Pheasant-tailed Jacana and  two Little Terns were at San Tin fish ponds on 19th. 

 May 20-31
Unsettled weather – mainly cloudy with showers, sometimes heavy. Temperatures remained in the mid-to-high twenties.
 
On 20th, a Japanese Leaf  Warbler was reported from Pak Sha O; the identification was based on call. The status of this species in Hong Kong since it was split from Arctic Warbler remains unclear, although it appears to be rare. This will probably be the 3rd or 4th record if accepted.
 
A Pectoral Sandpiper was at Mai Po on 22nd. Bird present on the reserve on 23rd included a late Tufted Duck, 17 Black-faced Spoonbills, 44 Eastern Cattle Egrets,  three atrifrons Lesser Sand Plovers, an  Asian Dowitcher and five Red Turtle Doves. The Tufted Duck and the spoonbills were present on 24th, as was the Asian Dowitcher among a total of 23 species of waders. Other birds on that date included an Oriental Pratincole and a  Little Tern. On the evening of 26th, a Slaty-legged Crake was heard calling on the reserve – an unusual location for this species.  On 30th, a Middendorff’s Grasshopper Warbler was trapped and ringed in one of the reed beds; this is the eighth record of this species in Hong Kong and the first to be found in spring. A Blue-tailed Bee-eater seen on the same day is a  new late spring record by three days.
 
Two Brown Shrikes were at Ho Man Tin on 24th.
 
A Von Schrenck’s Bittern was at Nam Chung on 26th, and a Blue-throated Bee-eater was seen briefly in the same area on 29th. This is only the seventh Hong Kong record of this species and is the first since one at Long Valley on 29 & 30 May 2010.
