We allowed the Swallows into the Information Room on the reserve and even supplied them with a shelf to build a nest to prevent muck going onto the info panels.
As you can see they took to this and built a nest and have already raise 5 young.
So for the second brood, are they going to use the same nest.
No, they built a new one on the Things You Can do/ Giving Nature a Home panel. Regular cleaning it is then!
