Two additions to this news blog: Firstly, 59 was still in PNG as of May 10, about 15 km south-east of Koroba. It seems that the window for departing to Japan must surely close soon – will 59 stay in PNG over winter?
The exciting news is that 59 has been in the Papua New Guinea highlands since April 26. We are still getting daily fixes which has given some really great information about where 59 is each day at midday. It seems that it is doing a final stopover near to locality of Koroba in PNG, before attempting its Pacific Ocean crossing to Japan.
心躍るニュースは、59が4月26日以降パプアニューギニア（Papua New Guinea、PNG）の高地にいるということです。毎日、59の位置情報をまだ取得しています。この位置情報で59が毎日昼頃にどこにいるかについてのいくつかの本当にすばらしい情報を得ることができます。日本への太平洋縦断を試みる前に、PNGのKorobaの近くで最後の休息をとっているようです。
The map below shows the last fix locations from Cape York and the recent fixes from PNG. For comparison, the fix locations of Nintai from 2019 are show in the inset. 59 is about 90 km west of the stopover locations used by Nintai from a year ago, and at a lower elevation (around 1500m).
Since our last update, snipe 59 has made its way to Cape York and is hanging around in what appears to be a creek line / wetland area off a tributary of the Coleman River. My colleague Eric Vanderduys, who has spent loads of time working on Cape York, sent me a photo of the habitat in the region. Pretty different to Canberra and Gwydir wetlands!
Snipe 64 had made another move northward and on April 15 was south of Grafton on the mighty Clarence River. Unfortunately, there have been no further transmissions since that date. It is probably too early to make doom and gloom pronoucements, as we have had Argos data delivery issues a bit recently. So fingers crossed 64 will suddenly pop up somewhere in the coming days.
After a week of waiting anxiously, wondering what had happened to snipe 59, the Argos data finally appeared online today. Even the data for snipe 64 were a day late. It isn’t clear why there was a delay in delivering the Argos data, but the wait was worth it. Snipe 59 is now in Far North Queensland, in the tablelands inland of Mission Beach. It is not far from the Herbert River at an altitude of about 700m. Very cool. It arrived there sometime between April 3 and 6. On its way north, it stopped over near the coast at a locality called Inkerman (south of Ayr) between March 29 and April 3. There was single fix north-east of Roma in southern Queensland on March 26, and prior to that it was north of St George and east of the Balonne River for at least 9 days.
Snipe 64 is determined to stick with the NSW coast, and is making its slow and steady way up the coastline. It most recent fixes have been from the floodplains of the Macleay River, just south of South West Rocks (since March 26). It was in the Dyers Crossing area (inland of Tuncurry) for at least 10 days prior to that.
I have been a little remiss in posting updates because I wasn’t quite sure what our two tagged snipe were up to. As of yesterday, ELF59 had moved from Gwydir wetlands, where it spent about a month, into southern Queensland. It is in a floodplain area between the Balonne and Maranoa Rivers. It has been there about a week.
Our other bird, ELF64, really seems to like the central NSW region and has not moved very far. It was still dam hopping north-west of Newcastle up until around March 6, then it moved north-east and has been near Wallamba River in the Dyers Crossing area (inland of Tuncurry) since March 11.
There hasn’t been any major changes to the whereabouts of our two snipe since the last update. 59 is still in Gwydir wetlands, spending its days and nights in different parts of the site. 64 is still dam hopping north-west of Newcastle, with no discernable pattern yet to its choice of wetland.
In other news, the Latham’s Snipe project has a few new sub-projects, in addition to the national surveys and the tracking. One is a social research / policy project exploring the on-ground changes that occurred around the time that the Japan Australia Migratory Bird Agreement was ratified. This includes gathering insights through interviews with ex-snipe hunters and government staff about what makes international conservation agreements successful or not. This research is being conducted by Federation University honours student Michelle Matthews under the supervision of Eduardo Gallo Cajiao (University of Queensland), Evan Hamman (Queensland University of Technology), Grant Palmer and Birgita (at FedUni).
The other project, which just started today, is a collaboration with Paul Sunnucks, Sasha Pavlova and Anna Polesskiy at Monash University to investigate the population genetic structure of Latham’s Snipe based on the samples we have been collecting from captured birds at Port Fairy and Jerrabomberra wetlands in the last 4 years. This will include sexing birds and determining whether the 2 “strange snipe” we caught at Jerra in 2019 are definitely Latham’s Snipe.
Finally, we have a new project commencing this year to develop a night time monitoring method for snipe using thermal imaging cameras along with more traditional techniques like spot lighting. An honours student will help with the feld-based research and be supervised by Birgita and Nick Schultz at FedUni, and Rohan Clarke at Monash Uni.
If you’re interested to know more about these projects, please get in contact with Birgita.
As of four days ago, our tagged snipe 59 was still in Gwydir wetlands and our other tagged snipe 64 was still dam hopping in the Lake Saint Clair / NW Newcastle region. Updated map below. The cool thing we found out today is that the two areas our Gwydir bird is using are quite different in habitat. The day time area is a mix of club-rush and cumbungi to about thigh height with some open patches of water, whereas the night time area has shorter and more open vegetation growing back after fire and drying. Very interesting to see similar behavioural patterns to that in urban areas in an essentially “natural” wetland.
Exciting news from our two tagged snipe! In the last two weeks they have both left the ACT and starting migrating northwards. ELF64 has stopped off in the Lake Saint Clair region north-west of Newcastle. The last fix was February 5, and the bird had moved a bit around that area in the previous 6 days. All fixes have come from small farm dams that look to be on private land.
ELF59 has made a surprise move by migrating through (or over) the Pilliga forest in northern NSW and onto Gwydir wetlands. Its last fix was on February 8 in the northern wetlands area. For those of you with good memories, this is a very similar path and stopover location our tagged bird Tsubasa took back in 2017. Hopefully, we have more luck with 59 and it continues onward from Gwydir (where we lost the signal from Tsubasa back in late February 2017).
This is just quick update to say that ELF59 and ELF 64 have been using the same day time and night time areas since the last update. ELF59 is in Jerrabomberra creek most of the time, even staying there sometimes at night. ELF64 hasn’t left the turf farm pivot since January 21. However, the fixes for both birds are now coming once every 3 days at midday and midnight, so we could be missing some daily movements. And the general lack of movement by both birds probably reflects their busy foraging in readiness to depart on northward migration.
There have been no further transmissions from ELF87.
All our birds appear to have been very active since releasing over a week ago. All three have been using the turf farm for midnight foraging, and almost always the exact same pivot! Obviously the regular watering of the turf is providing the birds with suitable foraging grounds where other choices are limited. Bird 64, which was our second bird released has been using some different daytime roost spots to usual, just north of the sewage farm. And bird 59, which has been sighted twice now by Alistair, has been in Jerrabomberra creek pool every day. 59 has even been snapped foraging during the daylight hours! So that has been great news so far.
Unfortunately, we have lost the transmission from bird 87 already. The transmission ceased completely the middle of last week, with no indications as to the cause of the problem. Given the abruptness of the changes, it seems like the tag might have failed. This is very disappointing so early in the piece, and with so few tagged birds out there. Nicki has been out over the weekend to see if she could spot 87, but with no luck.
The latest map is below. Midnight fixes are in yellow, and midday fixes are in blue. The last fixes from 87 around the paleo channels are in orange.
From January 18 onwards, the GPS program changes to once every 3 days, so that means we won’t get any more data downloads until next week.
