I stayed in the vicinity of this shaft from 2:30 to 3:00 pm and no rosy finches appeared, suggesting that rosy finches are not using these shafts, at least not this early in the winter. Several Red-tailed Hawks were seen, both light & dark phased birds. We returned north on US 95 via Hawthorne, Yerington, Fernley & then west through Reno to Truckee, then north to Sagen Creek Field Station. There we fed the birds extensively with canary seed & a few meal worms. The birds eat vigorously even when held snugly in the hand. Only a few of the birds had received any food up to this point (over 24 hrs since capture). We found that they could not husk canary seed unless it was first boiled (softened) but later I learned this was probably because my seed was old & dry. The wet seeds were usually husked before swallowing rather than swallowed whole though certain individuals appeared to swallow many seeds whole. Meal worms were sometimes swallowed whole, but more often they were cut up [illegible] into short pieces as the worm was worked down. Occasionally a worm would be cut in on or two places t
