While the jungles have a lot to offer from a birding standpoint, one of their drawbacks is that the heat and humidity molds hummingbird feeders very quickly; few of the lodges put them out. It was a lot harder to see the lowland hummers than the birds coming into the highland feeders. We spent a good amount of time staring up into a row of large orange flowering trees, trying to get on the birds before they could fly. It was pretty difficult.
Blue-throated Goldentail was a bird I was hoping to see. We did see several, but it was a tough bird to get a good look at; they didn't perch low. The bright pink bill was a better ID feature than either of the characters in the name.
I didn't really hope to see a Long-billed Starthroat, the book lists them as uncommon
White-crested Coquette is a specialty of the Costa Rican - Panamanian border area. The female is not that distinct. We saw good numbers of Black-crested Coquette last year on the Caribbean side.
Veraguan Mango is limited mostly to just Panama; it just crosses into Costa Rican in small numbers
Finally the ever-present Rufous-tailed Hummingbird
