Looduskalender has supplied this information, and more -
Last autumn a gale broke the home tree of the tawny owls. Craftsmen from the Keskkonnaamet (Estonian Environmental Board) and RMK (State Forest Management) made a nest stock for Klaus and Klaara from the same hollow tree and it was placed near the old nesting tree. On March 1st this year a small Mobotix infrared camera (Estonian representative Beta Group OÜ) was placed by Estonian Ornithological Society in the hollow, and IR illumination suitable for the hollow was supplemented by Videovalve. The tawny owls Klaara and Klaus have accepted the new nest stock and they started nesting on March 19th, before the camera stream was made public. We will see how Klaara and Klaus’s nest life will develop this year.

Renno sent three photos of the webcamera set-up.
and the nest, before the third egg was laid.
Renno said that, unfortunately, they don't have a picture or the time of the first egg.
The picture of the two eggs was taken on 22nd.
and next thing there are these 3 surprising eggs...
