Looking specifically at hummingbirds, I find that of Costa Rica’s 51 species (50 + 1, because of the recently discovered Rufous-crested Coquette) I have so far been able to find only 32 of them in the province of Cartago. Here are a few really nice photos, taken by friends, of some of our Cartago hummingbirds:

The Green-crowned Brilliant (Heliodoxa jacula) is mostly found on the Caribbean slope, where it is rated as fairly common. Here in my immediate area this forest species is not at all easy to find, but Larry was able to get the beautiful photo above at a friend’s feeders at Cabañas El Bosque in nearby San Rafael.
If you see a small, brown hummingbird in our area, it is most likely to be the Stripe-throated Hermit (Phaethornis guy). This bird was formerly known as the Little Hermit, which distinguished it from the also brownish Long-billed Hermit (Phaethornis superciliosus), a species that has not appeared here locally, to my knowledge, since it much prefers the lowlands. John Beer’s photo of the Stripe-throated Hermit (no stripes on the throat in its Costa Rica range!!) is from his garden in Santa Rosa:

Much more common around here than either of the above is the White-necked Jacobin (Florisuga mellivora), which is easily found for most of the year here near Turrialba. Larry’s photo shows the handsome male, while the duller female is mostly speckled below:

Birds for Beer 
Instead of ‘White-necked’ Jacobin, I always think, ‘Blue-necked’ as the blue is what’s so showy! They are all lovely!

I see from the distribution map that you have them in Ecuador too. Here they become quite rare between September and December each year. Perhaps they fly down to Ecuador!

Si; the Jacobins are here year round…One bird that surprised me last month on the Pacific coast was the Andean Coot…either that or AmericanCoot,which according to stats,is’extinct’ in Ecuador.. A long way from home, it was swimming in a smallsegua with the gallinules!
