Thumbelina's chicks almost ready to fledge

Everything seems to have happened very fast though it's already 5 weeks since I first spotted the nest. The chicks are now both poking their heads well out of the nest and looking around alertly. The nest itself has expanded in diameter and flattened somewhat. Tomorrow rain and wind is predicted but I think they will in any case soon fledge. Here are a couple of clip from this morning.
