1987 Ronald L. Grinell 2 Balanosphya formicivora Hastings Reservation (6 Aug) a complete turnover of the Arnold I birds. ② A large group of males from UA2 has taken over the A1 granary. This included (minimally) 81140, 81222, 81225, a-d 81027. All 4 of these birds were seen well and repeatedly in the A1 granary, wakaing, chasing intruders, etc. Three other UA2 birds were also seen briefly, could have Jav.1402 * 81340 Blk-wht(n)/M, 81026 Lgreen/LPink, and A1 Juvenile (8?!) 1380 M BIK-Lpink/Black /Red-DBlue. ③ With the UA2 8s a group of 3 89 from Keep Out. 81220, 81330 81332.

They also spent quite a bit of
