From 9 June 2020 video from England says about itself:
Swallows have laid their eggs at Saltram. Part 2 of a new National Trust nature series
Every year, in the machine shed at Saltram in Devon, a family of swallows build their nest. The swallows are not disturbed by sharing this normally busy working space with our gardens and outdoors teams.
This year, with lockdown restrictions in place and restrictions on visits, head gardener Martin Stott is giving us a glimpse into the world of the swallows. Every day this week, we’ll post a new video, showing how the birds are getting on. No swallows were disturbed in the making of these videos.
This video is the sequel.
