The bird was seen this morning in a Bamboo shrubland in HK Island, it has jump on the ground and fly to back to the branch near the ground. No sound was detected by this birds. It is around a asian brown flycatcher's size.   9:00am   HK Island Cannon EOS 20D 1.4x300mm       « Last Edit: Oct 10th, 2006, 2:02pm by Tony » Logged Mike Kilburn Committee Member BBS God     Posts: 334 Re: Unknown Bird--- Rufous-tailed Robin??? « Reply #1 on: Oct 10th, 2006, 4:33pm » Quote Modify Hi Tony     You are right  - this is a Rufous-tailed Robin - and a very early record!   At this timeof year you have to be a little acreful to separate it from the very rare Brown-chested Flycatcher, but from you pix you can see the grey patterning on the breast and belly, which the flycatcher does not show.   Cheers   Mike K Logged Mike Kilburn Vice Chairman Chairman - ConservationCommittee HKBWS Tony BBS Member BBS Full Member I love bird watching!     Posts: 44 Re: Unknown Bird--- Rufous-tailed Robin??? « Reply #2 on: Oct 11th, 2006, 12:09am » Quote Modify Thanks Mike. Is the Brwon Chested Flycather in the Birds of HK and South China? I can't find it.   Tony Logged Mike Kilburn Committee Member BBS God     Posts: 334 Re: Unknown Bird--- Rufous-tailed Robin??? « Reply #3 on: Oct 11th, 2006, 6:59am » Quote Modify The full name is Brown-chested Jungle Flycatcher.   There some pix on this BBS as several birds have been seen this year and last year. The dark pattern on the breast of the flycatcher is muchless extensive.   You could also check out the Oriental Bird Images website, which has a database of pix of Asian birds.   Cheers     Mike K « Last Edit: Oct 11th, 2006, 7:04am by Mike Kilburn » Logged Mike Kilburn Vice Chairman Chairman - ConservationCommittee HKBWS Paul Leader BBS Member BBS Senior Member     Posts: 83 Re: Unknown Bird--- Rufous-tailed Robin??? « Reply #4 on: Oct 11th, 2006, 11:08am » Quote Modify The light is very odd on this, but I think this is a first-winter female Siberian Blue Robin.  I think the flanks are too dark for RTRobin and there is no sign of the classic scalloping on the breast of that species.  RTR also shows strong rufous fringes to the primaries and secondaries (similar in brightness to the tail) and a pale throat which this bird lacks.  It is a first winter (note the moult contrast in the greater coverts) and first winter RTR show much more obvious pale tips to the greater coverts than this bird.  I suspect that some of the early records in the Avifauna of Rufous-tailed Robin are also Siberian Blue Robins.

But I think it is more likely to be a rufous-tailed robin rather than a 1st winter female SB robin after I check the photos on Oriental bird images since there appear some brown streaks/scales on the belly of the bird. http://www.orientalbirdimages.org/search.php?p=1&action=searchresult &Bird_ID=2573&Bird_Family_ID=&pagesize=1 Logged Paul Leader BBS Member BBS Senior Member     Posts: 83 Re: Unknown Bird--- Rufous-tailed Robin??? « Reply #8 on: Oct 12th, 2006, 10:33am » Quote Modify Still cannot see how this is a Rufous-tailed Robin!  First-winter female SBR do not have blue tails, they have dull brown tail feathers with brighter fringes, whereas Rufous-tailed Robins have uniformly rufous tail feathers (see link below) which this bird clearly does not have - note the darker central tail feathers.   http://www.orientalbirdimages.org/search.php?p=10&action=searchresul t&Bird_ID=2573&Bird_Family_ID=&pagesize=1   In addition I think picture 1 shows enough of the breast to show scalloping if there any and there is nothing of the indistinct malar and reduced supercilium in fornt of the eye usually shown by RTR.   I know it is also a small point but I think the pattern of the greater coverts is very important here and eliminate RTR.
