Cacomistle, Bassariscus sumichrasti, Los Quetzales Lodge

I have been to Panama four times, for long weekends in November 2013 and April 2016. And for a “mammal lite” week in May 2022 and an event liter week in 2023 (no trip report).

I returned to Gamboa in May 2022  and added Quichua Porcupine, Gabb’s Cottontails, Spix’s Disc-winged Bat and probable Tomes’s Spiny Rat and Kinkajou to the list.

Pacific Tent-making Bat (Uroderma convexum)

In 2023 I spent a couple of nights at the Toucan Apartments Airbnb in Gamboa itself – a convenient and comfortable place to say with Pacific Tent Making Bats in the porch and agoutis in the garden. A couple of night walks along the pipeline road produced a Northern Tamandua, many Gabb’s Cottontails, Mantled Howlers, Central American Agoutis and a brief but close and clear encounter with an Ocelot, about 1 km after the gate. Luckily I saw it well enough to realize that – try as I might – I couldn’t make the tail long enough to fit a Margay.

Northern Tamandua (Tamandua mexicana)
