1989 M. Stanback M. Formicivorus BIAN H/NHR Dec 88 Acorn Count: 2500 * * Group Update * 1518 disap 88 1112 รท 3W 21 Mar 1030 Hello holes - nothing. Saw 1517. 23 Mar 1150 Hello holes - nothing. 28 Mar 0900-0930 Watched. Saw 1232, 1515, 1516, 1517, 1519. Also saw 4 L.D.L (is this 1518?) These guys have @ 1000 holes in the dead tree by the nest tree (88) (1518 is DAP(n)/DG) 1 Apr 1200 Hello holes - nothing. Starling in bee tree hole. 5 Apr 0900 1 bird in hole above 88, 2 others to 88 hole. 10 Apr 1111 Climb 88 hole: 3 eggs! 2 round, 1 elongated. The long one (#2) and a round one (#3) had 'veins', the other round one (#1) didn't. I removed #3. 11 Apr 1100 2 new eggs - I removed both (pm nest watch) 12 Apr 1415 1 new egg (: total of 3 in nest) I let it stay. So 3+2+1 = 6 and if they lay 1 more = 7. Hardly a Flicker experiment (esp since they hatched > last year) Thus acorn woodpeckers can count. 20 Apr 1045 Well, at least they're Fertile... #1 24.8 18.6 5.25g -1= 2 27.85 18.05 5.7 12 24.24 18.15 5.1 95 22 Api back 5.3 Bird At 1500 I climbed + Found 2 hatchlings 33 L wing 5.75 + an unhatched egg. I put the 3 cvl R wing 8.0 cv1 kids in along with LW (whom I hope R leg 7.3 cv1 to Fatten up). I took 'Back' to the L leg 7.8 cv1 lab
