Journal 4.6 Km W Puerto Limon, Prov. Limon Costa Rica. 30 July For a short while we entertained ideas about heading toward Cahuita to the south. But the road is gravel and everything aside it is cultivated no forest. Instead we found this locality west of Limon secondary (perhaps tertiary) forest, well developed understory, Overstory project 40-60%. Rolling hills w/ slopes on 10% grade. Pleasant enough except for the bees and ants. leaf-cutting ants are in incredible abundance we set 180 traps here. I also set up 2 bat nets - one large, one small. 930pm arrived back on site to unfold the bat nets. 10pm In half an hour we netted nearly 10 Artibeus, and another unknown phyllostomid. 8 specimens were bagged (live) and the rest released. This was in the short (15') net. The large net (35') was left overnight. At the time of our departure at 1030pm there were no captures in this net. 31 July Returned this am at 7, found Desmodus, Artibeus & several unknown genera in the nets. Only one Desmodus. Probably 15 Artibeus. Four of the large bat of very long more leaves. Roughly half were released. Total count of bats kept can be obtained from the catalogue. The rodent catch from this locality was 9 Heteromys desmarestianus, 2 Oryzomy sp., 4 Nectomys (?) 1130am pack up & head west for San Jose.
