20 x 20 "extremas". By 6:30 p.m. I had caught 8 on my area, probably a few left but no definite sites. Others caught 5, 6, or 7. Caught a Pardal only 61 cm. apart. All of the "singers" noted so far have been males. March 21 Caught 2 Turaz on my area between dark and 8 p.m. Some singing after the moon came up. I think moonlight encourages singing. Checked traps at 5:30 a.m. Nothing on my area, but one trap was buried. Set traps in numerous old burrows and several near the buried trap, but no further evidence of animals on my area. Walked back to the Sfeelyta burrow. Golfin's is 170 m. beyond the first tree (2 owls, no pellets). 6 owls at the other, beyond Contreras' stakes but no more pellets. Found another burrow with a few pellets at the edge of the plowed field in Julio's area. Total 68 yrs pellets (dry lot). [illegible] Morning was partly sunny, warm, light breeze. Checked all traps at 6:30 p.m. April 14 Put 110 museum specks at 3 p.m. across the road from the original Eyzaga trapping place. Sunny and warm. No shuffling or running. April 15 At 9 A.M. traps held 45 Alcodon and 10 Dryzomys. None of the Alcodons with green vegetation in gut, none older than age 4; only 3 feeding males and one pregnant ♀ and 4 barren ♀. This locality on the Autopista to the aeropuerto & Eyzaga is 23 km SW of the center of Buenos Aires.
