Diagram of suture placement to affix GPS tag to a big brown bat (Eptesicus fuscus). (1) Suture with needle is passed downwards through the loop at the back right of the tag and is put through the skin into the subcutaneous (SQ) space; (2) needle (& suture) is tunneled cranially in the SQ space and pulled out at the cranial aspect of the tag and passed through the “tube” in the tag; (3) needle is pulled out the left side of the “tube” and inserted into the SQ space and tunneled caudally through the SQ space to the caudal aspect of the tag; (4) needle is pulled out of the SQ space and upwards through the loop at the back left of the tag; and (5) ends of the suture are tied together using several knots thrown over the site where the antenna leaves the tag.
