1977 Walter D. Koenig Melanerpes formicivorus Lower Haystack Hastings Reservation 19 May 1300. Hole opened: 4 babies, measured. Feathers not out of stein yet; eyes closed, lower mandible still >1mm longer than upper. 8RRR#236 seen hawking as I arrived. 24 May 1830. Watching from hide. Nobody anywhere at the moment. 1850. Babies are getting fed. Now in the main tree I see ①♂DBRW#309, eating an acorn. 1856. Several birds in main tree now, inc.②♂OrRW#307 and ③♀αm-Dr/M#170. 1903. ④♂RRR#236 fed babies acorn bits. 1930. Thought I had ⑤♀ub fora while, but I very well may not have. She is unfortunately pretty important at this point, and I'll have to return to look for her again. ⑥♀308 is very probably gone. 25 May 1030. Back again. It's fairly warm and pleasant at the moment. 1100. Now ①♂RRR hawking in old UHay granary. The other 3 also here: ②♂307, 309, ③♀170. ⑤♀ub possibly in nest. 1120. ③♀170 just fed the babies what definitely looked like a tent caterpillar, and a minute later I definitely saw her picking 2 others off the Valley Oak perch tree, thrash them about for several minutes to prepare them, and then go to the nest. Note also that getting these things entails "leaf gleaning" for sure. 1132. ③♀170 now doing some conventional hawking. 1145. Saved! ⑤♀ub definitely here; furthermore, it's that same ⑥♀ with the funny growth on her right tarsometatarsus, thus no doubt the same bird seen since at least 1975. All 5 birds were seen feeding the babies; especially the Malacosoma feedings by ③♀170 (perhaps only by her) noted above.
