Returning along Arroyo we found Ch.fallblandicus 6 by 0857 at 20m. 22 February Arrived at Grid 12 0640. No WR in go Arroyo on our way, although Ch.fall were present in small groups as seen other morning. G-Yeap and Blapwing calling before we got there. Nothing on Arroyo grid 10 experienced, but heard at 0641. Tuning remarkably similar to previous days, despite complete overcast. One pizachaca seen on route. Arroyo visible higher this morning than it was last night by around 30m of surface area. Water extends all the way to the south end of the grid in an inlet whereas last night it stopped 25m short. 0711 saw first non-feeding birds. Began taking samples at 0715 when NVR reached 4 foot and also. However by mistake I ceased a series of grid samples taken between 0717 and 0800, losing some birds concurrently as well. Lois began following birds at 0730. During the morning we followed 4 grids, including an banded WR (see space) renewed until 1140. 219 samples totals: White rump 27 (0-7) 90; Chardnius fallblandicus 24 (0-2) 37; Black marked stilt 0.5 (0-1) 5; Southern lapwing — (0-1) 1; Brown-headed gull — (0-1) 2.
