On February 2nd this year I saw my first tumulis. I Spoke with friends from here in e-mail and was asked for measurements and landmarks for repeat observation over time. The quest is to find out who it was and how they are doing.
This is an arrival / nest study. Please see the Associated observations Linked in order newest to oldest:
