All along the paths are sand piles mounted outside small holes and the other day we found a culprit, a Sand Wasp, see photo. These insects lay their eggs on dead prey, see the attached link, https://www.eurekalert.org/pub_releases/2017-11/uow-dwa110317.php
Bartsia is now in flower and we are finding it growing outside the usual areas, a good area is the west bank of the long pond and a small group can be found in the NW corner of the most northern of the small ponds.
Meadow Sweet is growing well this year, with a good clump just outside the entrance to the feeders.
We found a new Blackbird egg shell discarded on the path, a sign they are on their second brood.
