海外足旗涉禽目擊紀錄 Overseas leg-flagged Shorebird Sightings

Overseas leg-flagged Shorebird Sightings

Dear members,

You could see some shorebirds with colour flags in Deep Bay areas during this spring, please note flag(s) colour(s), position(s), species and percentage of breeding plumage of the birds. We could see these shorebirds with local flags (White over Yellow) and overseas flags (e.g. orange, orange over yellow, yellow, black over white, etc). Members are encouraged to submit these sightings of leg-flagged shorebirds, especially to those with overseas leg-flags. Such information could be posted here, or through email (bfspoonbill  @hkbws.org.hk) or PM.

Thank you very much
Yu Yat Tung

會員們, 大家好,

每年春天,米埔會有大量涉禽經過香港米埔,當中有些是帶有腳旗的. 除了有本地的(即上白下黃),也有一些是海外的(如黃,橙,黑,白等). 請你將資料記下,如顏色,位置,該鳥的種類,繁殖羽毛的百分比,然後把資料寄給我(電郵或pm),或張貼在下面.

謝謝
余日東

There might also be waders with colour rings like this Great Knot from Australia last year:

[url=http://www.hkbws.org.hk/BBS/viewthread.php?tid=13970&extra=page%3D4][color=royalblue]http://www.hkbws.org.hk/BBS/viewthread.php?tid=13970&extra=page%3D4[/color][/url]

in which the colour and position of the plastic colour rings and leg-flag enable identification of individual bird.

Please record the colour and sequence of rings/flag on each leg. For example, the bird in the above link is:

[b]Upper Left: nothing
Lower Left: yellow FLAG - red - lime
Upper Right: nothing[/b]
[b]Lower Right: blue - blue
[/b]
The easier thing to do might be taking a record shot.

Don't forget to record the SPECIES! Additional information on % breeding plumage will be useful as well.

Please keep an eye on them.

Thanks,

Katherine


此外, 鳥友亦可能發現繫有多個顏色腳環的涉禽, 如去年春季曾發現的一隻來自澳洲的大濱鷸:

[url=http://www.hkbws.org.hk/BBS/viewthread.php?tid=13970&extra=page%3D4][color=royalblue]http://www.hkbws.org.hk/BBS/viewthread.php?tid=13970&extra=page%3D4[/color][/url]

每隻涉禽個體的腳環及腳旗的顏色與位置不同, 因而可辨認每個個體.

請詳細記錄每隻腳上的腳環及腳旗顏色與位置, 例如以上連結中的大濱鷸是:

[b]左上: 沒有[/b]
[b]左下: 黃[u][i]腳旗[/i][/u] - 紅 - 淺綠[/b]
[b]右上: 沒有[/b]
[b]右下: 藍 - 藍[/b]

拍一張紀錄照可能是比較簡便的方法.

請不要忘記記錄該鳥的品種! 另外, 繁殖羽毛的百分比亦是很有用的資訊.

請幫忙留意, 謝謝!

Mai Po Boardwalk April 17, 2012

Curlew Sandpiper - Yellow flag on right tibia with the letters BTD. Metal ring on left tarsus.
The bird was mainly in non-breeding plumage with a few summer scapulars.

Flagged Waders at boardwalk April 17th 2012

I haven't reported any of these directly myself....

The Sanderling is from South Australia (combination orange over yellow).
I have made some enquiries about the unusual attachments (cable ties?) on the Curlew Sand, to see if anyone knows where this birds might have been marked.

Flagging interest

All the pics below were taken on 18th April 2012 from the boardwalk hides..

John,

Yes, the first one looks like to have black/green flags. So, it could be flagged at Thailand.

Please refer to:

It seems that the Curlew Sandpiper with cable ties on the legs (rather than flags) is one of 18 birds trapped on 19 and 20 September 2007 at Wonorejo, Surabaya, Indonesia.
We have previously had Curlew Sandpipers flagged in Hong Kong reported at Wonorejo.

Hi Kinni. I have received details for Great Knot RDZ.
This bird was flagged at Roebuck Bay, Broome, north-west Australia on 1st August 2010. It has been resighted nine times around Broome, but this is the first sighting outside Broome. Thank you for posting the sighting.

Hi John, it's so glad to know about the [RDZ],thank you for the information

Hi Thomas. Unfortunately not all of the stint flag is visible, and I don't think it will be enough to recognise the individual. I will send it to the relevant contacts in Victoria, Australia to see if there is anything they can do, but if you have any other photos of the bird's leg at different angles it may be very useful.

Today at the scrapes:

Red Knot: right yellow  83, left red-orange and metal, colour rings on tibia , metal on tarsus
Terek Sandpiper: right yellow BU on tibia

One flagged Dunlin seen on 19 Dec 2012 at Mai Po, Hong Kong.
Green/Orange and the flag was located upside the knee.

Some information on these birds:
Bar-tailed Godwit, yellow flag, DXE: Was flagged as a first summer on 3rd July 2010 at Broome, Western Australia. Was seen in Broome in July and August 2010, and in December 2011.

Bar-tailed Godwit, yellow flag, JJV. Was flagged as a second winter on 6th March 2012 at Broome, Western Australia. Was seen in Broome in March, April and November 2012.

Great Knot, yellow flag, VYR. Was flagged as a first winter also on 6th March 2012 at Broome, Western Australia. Was seen in Broome in April, May and July 2012

I also had a colour-ringed Bar-tailed Godwit on Friday, but haven't received details back about that bird yet. It would have been ringed either at Broome or at 80 Mile Beach, also in WA.

Based on these sightings, it seems highly likely that the influx of Bar-tailed Godwit (and smaller numbers of Great Knot) that arrived last week had come from Broome, where large numbers of these species spend the (northern) winter.

Ruddy Turnstone from Tasmania ? (orange over blue)

It seems that the orange flag is engraved. Do you have any more photos which may show the engraving clearly?

Mai Po boardwalk, 19 April 2013

Ruddy Turnstone with orange over blue leg flags, the orange inscribed DAM

Presumably the bird that was photographed yesterday

When I took the photos of this pair of Ruddy Turnstone, it was raining heavily outside & I was not aware of the leg flags. Therefore my camera didn't focus on the flags! Luckily Richard managed to note the engraving today!

The same Turnstone DAM was seen by Tung, Ivan and me on 15 April.

Grey-tailed Tattler : blue over yellow rectangular flags on right leg, (blue ?) ring above the knee on left leg

An unusual record. The blue over yellow combination indicates Bohai Bay. The ring on the left leg is probably a normal metal ring that has discoloured/corroded (this happens sometimes, especially I think with the rings used in mainland China)

I think this is actually a Hong Kong-flagged bird that has lost the lower flag. We have had this problem on a couple of Terek Sandpipers because we initially flagged them above and below the 'knee', and the lower flag has been lost (probably broken on rocks or eroded by sand). We have now started using narrower flags, both above the 'knee' to solve the problem.
Thank you for the report.

Sharp-tailed Sandpiper orange flag on right leg
Red-necked Stint orange flag on right leg
Red Knot yellow flag on right leg - 2 individuals (one with the flag plain, the other with numbers/letters on the flag but too distant to read)

There are actually 3 Red-necked Stint with orange flag on 4 May from Boardwalk.  One of them was photoed and posted by Natalie.  The second one was very similar to the posted photo (very low % of breeding feathers).  The third one had about 50% breeding feathers.

Up to 10 May 2013, we have collected a total 55 sighting records of overseas leg-flagged shorebird from BBS and the counts by our staffs in this spring. 15 of them are flagged by single orange flag from Victoria of Australia and 24 of them are flagged by single yellow flag from SW western Australia. But there are some interesting birds flagged in Thailand (Upper/Lower: Black/Green) and Tasmania of Australia (Orange/Blue). But the migration period is still going on, we still need bird watchers to help submit your sighting records on BBS or to our email: [email]legflags@hkbws.org.hk[/email]. Thank you very much.
