Much of this mountain range is difficult to access and some parts not always safe. However, Cuchilla de San Lorenzo is a ridge that is very safe for birders, easy to get to, and all but one endemic is found here. Minca is a small town part way up that birders often spend a day or two at, followed by a few days higher up at the fantastic ProAves reserve and lodge called El Dorado. There is also a research station nearer the summit that's possible to stay at if you can make the arrangements. My brother and I also stayed a few nights at a small village called La Tagua after our plans to stay at the research station didn't pan out.
I will do a separate post on the El Dorado Lodge and its hummingbird feeders, and another post on the endemics of this area. For now, here a few photos of some other birds we saw.
Swallow Tanager - very common along road here!
Black-fronted Wood-Quail (near endemic)
Blue-capped Tanager at feeder.
