J.P. Myers 1974 06 Oreopholus ruficollis Estancia Medaland, 35 km S. of Juncalito by road, Ptdo de Madariaga, Provincia de Bs. Aires, Argentina 4 September (cont'd) frequently fly of a kiskadee come to peck on a muddy woody stalk or prominent corpse. 4 or 5 birds may fly in front of a Pitangus thus - sweeping a path. Fluvialis does also. 1712 a Pitangus began hovering about 60cm above an Oreopholus. When this began the Oreopholus took the position described before but with much more frenzy - doing a dance in a circle with the wings held out and down. The Pitangus perched on a muddy weed and a 2nd Kiskadee flew in, landing on the opposite site approx. 60cm away. The Oreo. yanked low and stayed that way. Then ~5 sec later it stuck its neck way up and ran away. 1735 an Oreopholus took a large grub from beneath the surface of the soil and ate it. Grub was a minimum of 1" long, 1/4" thick, white - a classic juicy white grub, 8 September See journal today for notes on Oreopholus status now on Medaland 10 September See journal for census (11,20) Estancia Medaland, Ptdo de Madariaga, Provincia de Bs.
