Amazilia Hummingbird

Amazilis amazilia

The Amazilia hummingbird, scientifically known as Amazilis amazilia, is a member of the "emeralds" tribe Trochilini within the subfamily Trochilinae. This species is the sole representative of its genus and is adorned with a striking plumage that varies among its six subspecies, primarily in the colors of their throat and belly.

Identification Tips

Adults of both sexes possess a straight, medium-length bill that is pinkish-red with a black tip. Males of the nominate subspecies display golden-green upperparts and rufous uppertail coverts, with a tail that is mostly rufous but with bronze-green outer feathers. Their throat shimmers with a golden to turquoise-green, while the lower breast and belly are rufous. Females are similar but have additional white on the chin and throat and a paler rufous belly. Juveniles resemble females but with brownish edges on the feathers of their upperparts.


The Amazilia hummingbird favors open semi-arid to arid landscapes, such as scrublands, thorn forests, xerophytic steppes, and deserts. It is also a common sight in cultivated areas and urban parks and gardens.


This species is native to western Ecuador and Peru. It is a non-migratory bird, although some post-breeding elevational dispersal is observed.


Males are known to be territorial, defending their feeding territories from other hummingbirds and bananaquits. The Amazilia hummingbird spends a significant portion of its time perched, foraging for nectar, and occasionally hunting insects and spiders.

Song & Calls

The song of the Amazilia hummingbird is a series of squeaky notes that descend in pitch, with variations among subspecies. Calls include a "tsip" and a dry "zrrt," which can sometimes be extended into stuttering rattles.


Breeding occurs throughout the year for most subspecies, with the exception of A. a. alticola, which breeds from November to March. Females construct a cup nest of plant fibers and cobwebs, often adorned with lichen, placed on a flat branch. The clutch typically consists of two eggs, incubated for 16 to 18 days, with fledging occurring 17 to 25 days post-hatching.

Conservation status

The IUCN has classified the Amazilia hummingbird as Least Concern, with a large range but unknown population size and trend. No immediate threats have been identified, and the species is generally considered uncommon to common. However, deforestation poses a potential threat to the subspecies A. a. alticola, and A. a. caeruleigularis has a very patchy distribution within its restricted range.

I really like Birda
I really like Birda. I also use other birding apps and have Birda with E-bird going at the same time.
Learning Birding with Birda
I’m relatively new to birding as a hobby, and Birda is a great way to keep track off all the species I see. I’m still working on my ID skills, but the app is great for figuring out potential species, and the online community is so friendly and helpful. Definitely recommend Birda to both early and serious birders! 🐦
Makes you want to spot birds more
I think this app is fun. It makes you want to spot birds more so I guess in a way it encourages you to get out and about instead of sitting in front of the TV.

Birda is honestly the best bird logging app I have seen. I love all the features it has from being able to do a session and log all the birds you see in one sitting, to being able to connect with other birders from all over the globe!

A Friendly Place
I love using the bird app, I have a pretty good knowledge of birds. But I do have some gaps in it, so it’s nice to have a safe space to check on a sighting to confirm the species. It’s really enjoyable and I love the badges you can collect. It’s like a real life Pokémon go.
Love Birda
I love this app. It really encourages you to log your sightings and the community is friendly and helpful.
