On the 5th July the first eggs began to pip, 5 days on and we have 14 chicks so far!
The eggs are weighed regularly throughout incubation to track their progress but as due date approaches they are checked carefully for the first signs of hatching. At around 19 days of incubation the developing chick needs more oxygen than what it is receiving through the egg shell. It begins to move and with its beak pushes through the internal membrane to the air space within the egg to take its first breath.
Sometime after it gathers the strength to make the first tiny break in the shell. The chick at this point is pretty well exhausted. It can take another 3 or 4 days for it to fully release itself from the shell. During this time it is absorbing the last of the yolk that’s kept it nourished through incubation. It has also taken in some of the calcium from the egg shell itself to use within its body and also making it easier to break through.
Once we can see the external pip the whole clutch is moved to the ‘Hatcher’. This is because they now require a slightly different set of conditions to hatch successfully. The temperature is reduced fractionally and the humidity increased. When the chicks hatch they are given a colour ring so we can tell them apart, then they are put in a ‘Dryer’ where the temperature is reduced fractionally again and the humidity significantly lower.

Once dry the chicks are moved to a ‘Brooder’. Before being moved the are fitted with an additional metal ring and a white engraved leg flag. These are put on early in the birds life to ensure they acclimatise to them quickly.
In other Spoonie news 3 satellite tags have been deployed to 3 males. These tiny tags are solar powered and designed to drop off when the birds moult into their winter plumage on their staging grounds in China. We are hoping they may lead us to previously unknown staging sites on their way south from Meinypil’gyno.
To date 16 pairs have been found in the core area (3 more last last year) and 5 head-started birds have been sighted 1P, 1X, A7, 1T and Pink Left.
Stayed tuned for more updates soon.

Amazing update, enjoy hearing the technical detail, well done and thank your for your efforts and keeping us all informed at this next critical phase
Great news, well done all. Good luck with the rest of the hatching and rearing.
Congratulations Pavel and Jodie as well as all the rest of you conservationists from WWT and Birds Russia. What an incredible achievement and how fantastic that there are 3 more nests than last year. If the numbers are growing as a result of all your hard work + the work done in the Yellow Sea area by SBS in China and Save the Spoon-billed Sandpiper in the wintering grounds hopefully you have all prevented the terrible decline that was occurring up to 2010.
I love the incredible diagram of the chick inside the shell. Thank you also for the description about what is happening between pipping and hatching. This is definitely a post to be kept Jodie. Amazing how they are all wrapped up and no wonder their legs are so wobbly when they first come out of the shell. Helena
Well done everyone concerned.Please keep up the good work. It’s great to read all the latest news and see the wonderful photos,
Peter Soper.
Great news. Please keep up the great work. I have been following your work for many years and it provides me with great inspiration. Lets keep fingers crossed that the Governments and people of China, the Koreas and Russia are as excited as me and continue to give the support needed for success in the long term.

Excellent photos and so enjoying the descriptions of your work with the spoon bills. release pen very impressive!
We were very proud to be the ones that found 1X in May 2017 in Fujian, China and hope that it continues to do well.
