I’ve not been since 2013. I did go to the finca for the Parakeets, they’re seasonal I believe there. Going up Cerro Hoya can get you the new Mountain-Gem and maybe Glow-throated Hummingbird.
Mountain-Gem taxonomy is controversial but it is certainly a distinctive bird, just arguable if it is a species or if there should be a couple of big Lampornis lumps.
There is no doubt that Glow-throated is a good species. The idea that it might not be is, in my experience, based upon internet opinions from people without experience with the taxon (most of us, honestly!). At one point a fairly big/known voice in neotropical birding was widely suggesting it wasn’t a species. I thought that was a bold statement so I asked George Angehr (RIP) about it and he had no doubt about the validity of Glow-throated as a species and sent me photos of museum series. I am happy to repost them here later when home, but I was left with no doubt about species status.
However, from what I know, the last few people who have gone up Cerro Hoya have dipped Glow-throated also
A great place to start getting up to date info would be from Kees and Loes at Heliconia Inn, who are also a good choice to organize a trip (highly recommended, also great snorkeling and just beautiful) to Coiba for the Spinetail and Dove.
