Also caught 1513, Immr♂, st 4,8 with ORANGE visible in his ears (offspring of 0020).

AE This PM on GRID RC drift fences I dusted ♀ 0340, lctd, st E-B, with GREEN powder; ♀ 1183, lact, st E-B.5 with ORANGE powder. On the grid caught ♂ 0130, st 5,9 covered with PURPLE powder and ♂ 1524, st 4,8 covered with fresh ORANGE * powder (from 020 ♀♀). *This contact is intriguing because ♀ 020's mate, ♂ 1257 was recently eaten by a Crotalus and she has given birth since then (see Ann notes above). 1524 is a definite immigrant and I wonder if he is taking care of 1257's pups??!
