1981 R.L. Munne Melanerpes formicivorus Blom-one 24 April Start 1145. Wild. The 3 1500 ♂, plus 3 cooperating unbodied ♀♀ seen to have control of the granary. Haven't seen ♀478 yet. 1155. Now I see her, but she's in the trees 20 feet SW of the granary, chasing others. She seems to be walking with a ♂NB, and chasing violently a ♀NB. Have not seen ♀478 in the 120° granary, which at the moment (1220) is under total control by the 1500 ♂ and the 3 ♂NB, 1224. Looks like 2 ♂NB are with ♀484 in the peripheral trees Have not seen ♂84 yet. 1250. Winding down a bit. The very peripheral birds have thinned out. Now down to the hardcore: 3 1500 ♂, 3 ♀NB in control of the 1°g; ♀478 and 2 ♂NB controlling the area from 20 feet S of the granary South next Forgot to action $509 Gazebo Don't (Yellow) See her at briefly at about noon Probably a maximum of 12 birds when I first arrived. 1300 Now starting to see the opening flurries between the 2 factions, right at the boundary between their respective territories. End 1315. Going to see if any of this has spilled over into Gazebo 25 April Start 1015. Very quiet! Here 5 min before I heard so much as a waka. ♀478 and the 2 ♂NB have lost ground. They now seen restricted to the two Valley Oaks, 20m E of the small dry cattle pond. (45 m Wofgranary). At yesterday 3 ♂NB and 3♂492, 493, +622 from 1500 are in control of the granary and almost everything else. I'd say this revolution is over. End 1160. No other intruders around, 13 May Very quiet here at 1430. ♂492 0-/BLK + ♂622 seen, plus a ♀, but don't see anybody else around.
