A lot has happened since the last update on the 19th July. Here’s the story so far…
By the 12 July all those that were able to hatch had done so. In the first 24/48 hours of a chick’s life it gets nourishment from the remaining yolk inside its body. This gives the chicks time to dry and rest before having to venture out and find food and water. As the chicks become active we move them in groups of 4 or 5 according to age and strength from the ‘Dryer’ to the ‘Brooders’. It was clear early on that 2 chicks were noticeably weak for their age. Though it was touch-and-go at times with some TLC, high energy supplement and careful monitoring they soon joined their brood-mates.
The chicks are initially fed a pellet diet made especially for waders and insect protein mix, all crushed up and served in small dishes of water. Around the brooder we also sprinkle mosquitoes (fortunately the tundra is full of them!) and dry insect mix. These contrasting colours on the brooder floor stimulates them to peck and eat. Spoon-billed sandpipers are precocial birds which means they hatch well developed with the ability to feed themselves. At around 3 days old they are also given live aquatic invertebrates, mostly Daphnia. The movement of these also stimulates them to feed and marks the start of their ‘training’ to being totally independent. During the indoor rearing phase the chicks are monitored regularly and the food dishes changed every 3 hours, day and night. Ivan and Nickolay take most shifts, all between building the release pen, catching Daphnia and mosquitoes! Absolute heros.
Each day the temperature is decreased and less food is crushed until around 7 days old they are moved to the release pen. At first they are put into small coops with heat lamps until they adjust to their new climate. Soon the coop door is opened giving them access to a small corral. Each day the corral is made slightly bigger until two groups merge into one. Finally the corrals are removed giving them all access to the entire release pen.
The youngest birds are now 15 days old. Most of the downy feathers they began with have now been replaced with juvenile plumage. Their bodies are now more proportionate to their legs and the bill has elongated much resembling the adults.
In other Spoonie news, the pairs who’s first clutch was collected for headstarting have now finished incubating their second! This is a good opportunity to catch and ring adults and their new broods.
Only a few days left until release! Stay tuned for updates soon.

Apologies for the delay in posting this. Been on holiday. More blogs coming shortly, if a bit belatedly.
Absolutely brilliant, amazing to see incredible dedication and expertise, a real inspiration! Fabulous work, well done everyone!
You are really demonstrating how we can deal with international problems if we all co-operate. An example for the whole world. You really are international heroes.
Just amazing to see the work done and to see the chicks.
Fantastic! The well-oiled headstarting machine rolls on, achieving great things year after year. You’re starting to make it look easy, but we know it isn’t! Well done all.
Wonderful work. Well done everyone and good luck to the chicks.
Congratulations all in the field. You are true heroes and heroines. How incredible that you managed to rescue the two weaker chicks and thanks Jodie for the very good explanation of what occurs over in Russia. Ivan and Nickolay definitely deserve gold medals for all they did not only getting food, and feeding regularly during the night but also building the release pens. A real marathon but SO well worthwhile if we manage to save the Spoonies.
