(very) local goodies

Early morning birding at the government compound near my house produced a few migrants this morning, with two Ashy Drongos of the uncommon mouhouti race which I only ever see in Bangkok as a passage migrant.

I then picked up the soft "tack" call of a Cyornis flycatcher, which eventually revealed itself to be a female Hill Blue Flycatcher - a rare passage migrant in Bangkok. 

Whilst trying to relocate the Hill Blue Fly I found a Paradise Flycatcher, which gave poor and distant views  but from the images I got of it, appears to be a Blyth's (identified by the greyish throat, which would be blackish in Amur PF). The same small group of trees also held single Arctic Warbler, Taiga and Asian Brown Flycatchers.

Incidental birding

Work and family commitments have kept me away from any dedicated birding odf late, so I have had to make do with slim pickings - but any free moments have been rewarded - these included migrating Ashy and Crow-billed Drongos near my house, whilst a weekend at the beach at Hua Hin managed to produce an impressive migrating flock of 60 Grey-headed Lapwings, two Hoopoes and an Amur Wagtail whilst lazing in the pool!  This morning I was at a major "spaghetti junction" in the centre of Bangkok doing the school run when I spied a Paradise Flycatcher spp sallying between two highway ramps!

Scarce and hard to ID migrants

1CY Dark-sided Flycatcher

A very productive morning at Suan Rotfai from 0630-0915 hrs, with one of the first birds encountered being a  Two-barred Greenish Warbler that called whilst flying from one clump of trees to another, and uttered another couple of calls once perched, hidden in the foliage.

Soon afterwards I heard an Amur Wagtail call as it went high over the park, and then was alerted by the call of a pair of Grey-headed Lapwings (only my 4th patch record) that I eventually saw twice going over the park.  Once the sun was properly up my attention turned to passerines and I soon found an Arctic Warbler (sound-recorded, ID confirmed as borealis), followed by my first Taiga Flycatcher of the autumn and a pair of Sakhalin Leaf Warblers (ID'd on call) and two Common Kingfishers.  Further on along the canal zone I caught a movement out of the corner of my eye - an apparent Asian Brown Flycatcher, but given that the bird had dropped out of a large, bare, dead tree I was suspicious that it might be a Dark-sided Flycatcher; my suspicions were confirmed from record shots of the bird in deep gloom (the power of digital photography!) before it gave slightly better views - a scarce autumn migrant and the only 1st calendar year bird that I have ever seen!  Whilst waiting for it to reappear I also picked up a female-type Yellow-rumped Flycatcher.
rather blurry Sakhalin Leaf Warbler

Heading back towards the park gates I checked another couple of areas and was rewarded with a Alstrom's Warbler -  a scarce autumn migrant here, as well as more usual fare in the shape of two Asian Brown Flycatchers, two Brown Shrikes, 1-2 Black-capped Kingfishers and a pair of Eastern Crowned Warblers one of which was poorly-marked (hardly any yellow in the vent), poorly seen and hence very confusing.

Not a bad start to the day!

Hainan dipping blues

A bit of dirty twitching after work at Suan Rotfai yesterday (21st) turned into dirty dipping when the targeted Hainan Blue Flycatcher did not materialise - it had been seen earlier in the day by other regulars but decided to depart before I could get there.  I thought that it was supposed to be a dowdy female but saw images of it on-line when I got home, it was in fact a stonking male. Ouch, that would have been a juicy patch tick.

For my troubles, I did manage to find a (silent) Sakhalin/Pale-legged Leaf Warbler, which was my first of the autumn. I also had a cunning plan to check the now floodlit areas of the park after dark in the hope of snagging myself a migrant Grey Nightjar (another much overdue patch tick) but the heavens opened after I got glimpses of a Drongo spp (probably Crow-billed) leaving myself and a dozen joggers to spend the next hour and a half sheltering from the downpour in the gents toilets!!!!

This morning (22nd) I made a return to the park for 90 minutes, with the Hainan Blue confirmed gone I sought out my own birds and managed a reasonable haul of common migrants:  two confirmed Pale-legged Leaf Warblers (both calling and one responding to playback), a single Arctic Warbler (which remained silent but came in to check out borealis play back having completely ignored Kamchatka LW payback), two female-type Yellow-rumped Flycatchers and two Asian Brown Flycatchers.

Unshrike-like Shrike

I checked Suan Rot Fai's "Secret Garden" area this morning, with a limited number of migrants found - single Eastern Crowned Warbler and Asian Brown Flycatcher, but the highlight was a juvenile Tiger Shrike seen a couple of times, but often elusive.

Whilst Tiger Shrikes look pretty much like any other Lanius their behaviour sets them apart - sticking to the understorey or within the cover of the canopy, and often flicking the tail up and down whilst also fanning and closing it. Today's bird spent a few minutes foraging inside an area of rather dense scub, acting more like an Acrocephalus warbler than a shrike!

Black-backed Kingfisher

After returning from the UK, one of my first duties was to do the school run on the morning of Thursday 14th September.  Fortunately my goddaughter's school is close to Suan Rot Fai, so it was a minor detour for me to stop by and catch up with this migrant Black-backed Kingfisher.  This absolutely stunning bird was offering point-blank views to anyone who cared to attend. 

The pictures were taken with my  Nikon V1 matched with the Nikkor 300mm f4 VR PF lens, and speak for themselves...

Hell in Paradise

The recent split of Asian Paradise Flycatcher into three species caught me and a fair few others unawares and has sent us scurrying off to figure out if we have seen all three, which are:

Amur Paradise-Flycatcher Terpsiphone incei (monotypic)

Blyth’s Paradise-Flycatcher Terpsiphone affinis 
(includes burmae, indochinensis, affinis, nicobarica, madzoedi, australis, borneensis, procera, insularis, sumbaensis, and floris)

Indian Paradise-Flycatcher Terpsiphone paradisi 
(includes leucogaster, paradisi, ceylonensis, and saturatior)

I was fortunate to be aware that most of the Paradise Flycatchers that I see passing through Bangkok are incei (= Amur), but had also seen a indonchinensis (= Blyth's) there in winter 2014/15, with another in Feb 2016.  It seems that saturatior Indian Paradise Flycatcher winters in southern Thailand (Round, 2008), although there is some debate about whether saturatior should be considered to be part of the Blyth's group, rather than Indian.   My interpretation is therefore that in Bangkok Amur is an autumn passage migrant, whilst Blyth's is the common Paradise Flycatcher in Thai forests year-round, with mid-winter wanderings further afield, eg.into Bangkok.  Saturatior (Indian?) needs to be looked for in peninsular Thailand in winter and on passage.

The bird in the two images above was the first Paradise Flycatcher I saw when I started working my patch, eight years ago.  At the time Phil Round commented: "The blackish throat contrasting with the grey breast and belly tells you that this is the migrant race, incei. Clearly bluish bill and orbital indicates an adult (greyish, bill flesh-based in 1Y), so presumably a female."

2nd Calendar Year Blyth's Paradise Flycatcher, Feb 2016

The Blyth's Paradise Flycatcher above is a 2nd calendar year (ie, 1st winter), aged by its flesh-coloured base to the bill. The grey throat, with black limited to the crown identifies it as indochinensis.

It is important to note at this point that the upperpart colouration is pretty similar in both these birds, but in adult males, Amur is distinctly brighter than Blyth's.

From memory, I have never seen a Paradise Flycatcher in Bangkok on spring passage, and if I were to do so I would examine it very carefully as it seems that this is by far the best time of year to find Japanese Paradise Flycatcher -  a scarce migrant in eastern Thailand, and pretty much a vagrant elsewhere in the country. Round (2008) notes that (at that time) Japanese Paradise Flycatcher was "only known from one record in the Bangkok area, and relatively few others nationwide" and called it "a very rare spring and autumn passage migrant", furthermore noting  that many claims of Japanese might be erroneous. Recent migration studies on Koh Man Nai have demonstrated that Japanese Paradise Flycatcher is actually a more regular spring bird than thought back in 2008, but I am only aware of one more Bangkok record (also in spring).

So, I was happy with having determined that both Amur and Blyth's Paradise Flycatchers occur on my patch, and that I'd need to look carefully at any spring Paradise Flycatcher to see if I could snag myself a Japanese scarcity.

Then on 19th September last year I photographed the bird below.  It was the second of two sightings I had of Paradise Flycatchers in the park that morning, but both were very brief encounters, with this bird offering itself for these images and then promptly disappearing.

At the time I figured: September  = Amur and thought no more about it.  However a few months later Dave Sargeant was reviewing his and other images of Paradise Flycatchers to try to work out which ones he has seen, and contacted me to ask if I thought this bird might be a Japanese Paradise Flycatcher because he considered it to be rather dull.  To my mind the ID criteria of 1st winters was that Japanese should have significantly duller upperparts than Amur or Blyths, and whiter under parts, but knowing that this was a tough bird to claim I was extremely cautious. In due course I posted the images on a couple of forums, where other well-respected birders, including Andy Pierce and Dave Bakewell were supportive of a Japanese diagnosis, though one experienced ringer was less convinced.  However, with ringers on Koh Man Nai having handled more JPFs this spring there is now a unanimous consensus that this is indeed a Japanese Paradise Flycatcher, based upon the combination of non-rufous upper tail and what can clearly be seen to be uniform sooty blackish primary coverts (compare the primary coverts with the Amur at the top of this post).

Needless to say, I will be looking extremely carefully at all the (spring, autumn, mid-winter) Paradise Flycatchers I see in future!
