J.P.Myers 1974 Tryngite subroficidis 53 Tower grids, (1,18) region, Catania Wieland, 35 km S. of Juancho by road, Ptdo de Wladarioga, Provincia de Bs. Aires, Argentina 12 November (Cont'd) flew in a circle around what it had understood to be to borders - flight a gliding type, landing at various points in the circle near after other birds + then flying again. 1220 - bird on 176 remarkable for the amount of time that they have been preening + poor concentration lack of aggression. Then just at 1228 a few began feeding and 2 supplanted (other). 1253 - the flock took off for the Arrapo - going low ad east in a fairly direct fashion, all visible left. landing picking up feeding again. then direct turned arrapo. a dramatic event: However within the next five minutes birds began arriving before 1300 and by then there were supplanted the sites of supplantation were consistent with this area's territories. 1306 - simultaneous supplantations. 1307 again - a heli flight from 7 m. Buffy did not stay off grid as long as they did last month - perhaps the cool + very damp weather is responsible. 1510 golden called again but none left. [Note - Lois followed buffy from 1134-1153 on 164, supplanted consistently for- first 12 minutes + then stopped. some confusion so to exact ID. then after several minutes of hovering the encroachment of another bird it supplanted. For the next hour it was being consistent, this bird, however, appeared more 'drunk' or hunting: if it was preening then encroachment was guaranteed until the preening session was over. Further, supplantations were quite - a lot of perimeter walking, and raising little runs - would have off rather than chase. However, there were also several light/drift helicopter supplantations (one of which resulted in the chased bird running away with raised wings) showed border ~ 8m toward tower from (0,0) unit.] 1324 - Supplantation from (0,1) -> (1,1). same supplanter has been active all morning. 1351 - Sup. in (0,0) - chased bird shunned away up. does that mean it was returning to its own turn? 1451 - all birds took off and are flying over the field headed toward arrapo, but came back + whirled over the (1,18) region. 1456 - Tryngite returning to grid + immediate supplantations 1458 - same bird supplanting, followed by gliding around in circle area territory in same place where this happened before. After 1500 we began taking peek data - counting #'s pecks/15 sec. for a 2 min period after a single buffy. Data in Grid 16 looked like pattern on 176 and broken down by sub unit. 1504 - side run supplant revealed into a hopping flight, then flight clear - the supplanting bird (same)
