"cheer", lots of roll on the last, almost separate notes. Hummingbirds nesting. Fog lowered onto Cerro Campana at about 4:30 and lifted next morning. Forgot to mention Zorzilicinia singing in the lower part of Acari and saw English Sparrows there also, No early bird chorus. Had been a little dew drip off of car but it was dry at daybreak and grass/weeds dry, but a tuft of doceron fluff marking a trap was covered with dewdrops. Foggy, but soon clearing. Avita line of about 50 small traps caught 2 mice and 1 big/pregnant female Phyllotis darwin. Lots of her traps springing & empty, Bird caught only: #645 A8 Phl dar & vog open, tail short #646 H6 Mus J sd. #649 J2 Phyllotus dar J sd. Saw a big Oryzomys several times yesterday and this morning 50 yds. from the tent in a pile of stones & cactus, another about 300 yds down the road, set numerous dry Sherman for them but they don't seem to go into them, while jock-fighting, this second guy charged down his runway, jumped into the back end of a Sherman, thereby springing it, and escaped. Filled in the rest of my grid with small Shermans, so now a trap at each station except the three where mice were caught last night. Avita added
