I have visited Ecuador three times: in August 2012 for a week to see Spectacled Bears and Mountain Tapirs in the Andes, and then to the Napo Valley; for a long weekend in September 2015 to look for Olinguitos; and then in 2021 for a week in the Galapagos and a week in the Andes and Napo Valley.
Bellavista Lodge and Mindo
During 3 nights in 2015 we saw Olinguito, Kinkajou, Andean White-eared Opossum, Red-tailed Squirrel and Tube-lipped Tailless Bat plus a couple of hard to identfy rodents, one of which was most likely a Grey-bellied Nephelomys.
In 2021 I spent another night at Bellavista and saw some of the above. I also spent many hours at the San Tadeo Birding Garden failing to see a Mountain Coati among the Red-tailed Squirrels and the occasional Central American Agouti and an Ecuadorean Small-eared Shrew.
Cayembe – Coca National Park
I spent four days here in 2012 and saw Spectacled Bear, Mountain Tapir, White-tailed Deer, Andean Rabbit, and Andean Fox.
Returning for a night in 2021 I added Stump-tailed Porcupine to this list.
An hour at the Guayango ecolodge close to Papallacta was plenty of time to see a colony of Montane Myotis.

The Mammals of Ecuador is a brilliant resource. This has a full list of all Ecuador’s mammals and – if you search (Buscar) by species – you can get detailed photos of each species. If only every country had one of these.
