(1 March) gone that I'd put in last week. I put in 60 more (all old Q.douglasii) and put up the net.
2 March I'd left the net up and so checked it during today's snowstorm at 800 and 930 before taking it down. Noone was in the net nor had apparently visited the tree.
3 March Acorns still apparently untouched when I checked today.
8 March 930. All acorns had been eaten, no birds were around. In addition, one of the side limbs fell during the storm, taking nearly 100 (my count: 91) holes with it. I put in 75 more acorns (all Q.agrifolia) to keep things lively.
9 March 1230. Noticed a bird here, so I came over to put up the net and discovered that all 75 acorns were already gone! So I put it up anyway and stuck in 50 more acorns which I happened to have handy.
1600. Caught a bird, who turned out to be B#22 (the 2nd yr. bird from Y). He was processed and released at the lower barn.
10 March 700. Came by to check the net, discovering 2 Scrub Jays in the tree, one of whom appeared to fly off with an acorn in its bill.
900. Bird in net: unbanded ♀, probably 1st year bird. She was banded as #257 (with a Yellow wing-streamer on her right wing) and released at 1000. 1030 Cooper's Hawk perched in storage tree; flew off towards Hill.
1100. Banded Brown Towhee (#702-57146) in net.
15 March 14(5). Put in another 97 acorns in the holes; none of the others remained, of course.
1430 Saw a Scrub Jay in the storage tree trying to filch an acorn as I drove by.
16 March 1100. Nearly all the acorns are gone; eaten perhaps mostly by Jays-
