Melanerpes formicivorus
Road 3
14 June 1230, these guys are a real problem. Egg #1 is gone without a trace, #3 & #4 still unhatched though it seems to be getting late
15 June Starting a combination nest watch and group watch (looking for juv. dominance) at 0800 Incredible flycatching frenzy, starting about 0850! Between 0917 ad 642 > (10min),
-> 114 separate flycatching sorties, all by the core 3!
114 in 10min! A frenzy if I ever saw one. The insects were all stored in the storage holes at the nesttree. Frenzy began about 0850, wound down about 0950. At one point, a Grosbeak joined in the flycatching from the nest tree, chased out, however. Insects could have been predom. Lady Beetles
Checking the nest at 1300, still = eggs.
16 June Nest check at 1815. Finally, egg #4 has hatched, apparently today. I magic mark him on his left heel and foot. Egg #3 Still doesn't look very serious. This was day 12 for #4, day 14 #3.
18 June Nest check at 1630, only one live baby. Egg #3 has a pinhole crack in it, and had been drained of its contents, It apparently did not develop.
21 June Roosting and old reliable O184 roosted.
29 June 1200' Nest check, after an "orphan" from westgate introduced. The "real" nestling weighs 55g, the orphan (black band) 38.5
3 July Nestcheck, the original weighs 73.5g, black band weighs 63.5 g
22 July Start 1220, J538 Yel/Bik - Yellow here. He's eye looks much better, and it also looks like he's in adult O plumage. Probably wrong.
