Silky Anteater, Cyclopes dorsalis, Manuel Antonio
I have been to Costa Rica three times. In 2010 I spent 9 nights here and I return to Sylvan, near Golfito, for a weekend in 2019. In early 2021 I spent a week with Fiona Reid traveling through the mountains and then back down to Sylvan.
Honduran White Bats, Ectophylla alba, Tirimbina
I looked for Montane Squirrels here for a day in 2010 but found only Red-tailed Squirrels and a rabbit species that might have been Dice’s Cottontail but probably a Tapiti. I returned for 24 hours in early 2021 to look for Bang’s Montane Squirrel. The park is very strictly controlled now and we didn’t see any squirrels, though we did catch some Talamancan Deer Mice in the hotel garden.

In late November 2019 I spent three nights visiting Fiona Reid at her new ecolodge, Sylvan (as of early 2021 boasting a lodge list list of over 80 mammals) and returned in 2021 for two nights. My 2019 visit was not a mammalwatching trip per se but of course I saw a few species, best of which was undoubtedly Peter’s Disc-winged Bat. In 2021 we spent two nights batting quite intensively and caught 15 species: Proboscis Bat, Greater Fishing Bat, Orange-throated Bat, Hairy Big-eared Bat, Common Vampire Bat, Common Long-tongued Bat, Chestnut, Seba’s and Sowell’s Short-tailed Bats, Niceforo’s Big-eared Bat, Northern Yellow-shouldered Bat, Northern Little Yellow-eared Bat, Jamaican, Great, Pygmy , Thomas’s and Watson’s Fruit-eating Bats and Black Myotis plus Central American Squirrel Monkeys too.
