Here is one of the first feathers to arrive. This takes considerably longer than the minute between trips that it took the bird to find grass and stems. Here is the bird, roosting in the new nest for the first time, about 48 hours after starting to build. As the nights are still cool, the bird fluffs up its back feathers and tucks its head under its wing to go to sleep. Here it is on the following night, just into the fourth period of 24 hours from arrival.
Feathers continue to be brought.
We now await further developments.
