The asteroid belongs to the Themis family, a group of asteroids named after (24) Themis . The timeless (non- osculating ) orbital elements of (8963) Collurio are almost identical to those of the two smaller ones, assuming the absolute brightness of 15.5 and 14.5 compared to 13.2, asteroids (78540) 2002 RH 117 and ( 144667) 2004 FQ 7 .
(8963) Collurio is after Neuntöter named, whose scientific name Lanius collurio is. At the time the asteroid was named on February 2, 1999, the red- backed shrike was on the Dutch Red List of Endangered Species .
