1988 M. Stanback M. Formicivorus CUL H/NHR 30/Mar 1130 Bird at syc slit-hole Dec 87 Acorn Count: 4500 2 Apr 1115 You can see down the hole - its ready to go, but how to cut it open. It's at least 6" thick from all sides. 8 Apr 1700 4 eggs - couldn't reach 'em. 9 Apr 0915 Widened the hole a little enough to get my hand thru the marrows, but then my forearm stuck there before my hands reached the eggs. There are not 4, but 9 eggs! By using the mirror, you can see the ones I missed yesterday. They are opaque. Even though it widens out, I don't think I could cut. 10 Apr 1000 Cut new door, but I Fucked up and punctured 2 of the eggs. Look, no one is more upset about this than I am - this was going to be great brood reduction. I'm punishing myself. Both eggs were removed - both Fertile - incub @ 7 days. Well, we can still get hatchability data (2+x) and number Fledged (there will still be brood reduction) 13 Apr 1440 Well shit, they've hatched = and it looks like they hatched on 11 Apr - or started then - I can only assume that the 2 eggs I broke were runts (I actually only opened 1 of them - I need to check the other.) So 9 laid, 9 hatched (a record?) Very synchronous too.
