1983 R.L. Mumme Melanerpes formicivorus Road 1 17 Jan ** GROUP UPDATE ** ① ♂577 + ♀806 found DOR 25 Aug 1982. [by WDK] 21 March Watching, 1020: 1110, Complete census: ♂496 ♂294, ♂269 ♂383, ♂578, ♂579, ♂580, ♂672, ♂804 all seen well. Only other thing of note is that the 81-82 nest limb (Black Oak) broke below the nest hole, at the lower hole that was never used. Fortunately, the nest looks OK. 31 March As it is definitely becoming spring (warm, mostly sunny AM), I start a watch from PO Hill at 0930, looking for signs of mate guarding or interest in holes. I notice that a top chunk of the 1° granary has broken off, right at the spot of the upper of the two roost holes there. 1040 Doesn't look like much is happening. Didn't seem like ♂486 was showing much interest in ♀269. The birds were hanging out a lot around the Black Oak nest hole (eating catkins, mostly) but nobody looked at the hole. Still, it's possible that they could be interested in the low hole in the sycamore, since I couldn't see it. 1130, After seeing Rd 1 birds hanging around in a sycamore adjacent to the creek (Arnold side) [illegible] m downstream from the bridge, I find what appears to be a fresh hole start Not too high, in a live part of the tree, with a nice live branch below for standing on. Will have to keep an eye on it. Unfortunately, the hole faces South, not visible from PO Hill
