Ruby-cheeked Sunbird

Chalcoparia singalensis

The Ruby-cheeked Sunbird, a diminutive and vibrant bird, belongs to the Nectariniidae family. It is the sole occupant of the genus Chalcoparia, a name that evokes images of bronze-cheeked beauty, which is fitting for this species with its striking plumage.

Identification Tips

Males of the species boast a glistening throat patch, which can appear ruby or iridescent depending on the light. Females, while more subdued in coloration, share the same delicate features and slender bill, adapted for nectar feeding.


These sunbirds inhabit a range of lush environments, from the lowland forests to the mangroves and even the moist montane forests, each providing a rich tapestry of flora for these birds to thrive in.


The Ruby-cheeked Sunbird is a resident of a broad swathe of Asia, from the eastern Himalayas through Southeast Asia, extending to the islands of Sumatra and Borneo, and reaching the verdant landscapes of Java.


Agile and active, these birds flit through the foliage, their flight a blur of iridescent colors as they search for nectar and insects, which make up the bulk of their diet.

Song & Calls

The vocalizations of the Ruby-cheeked Sunbird are as delightful as their appearance, a series of high-pitched notes that add a layer of acoustic beauty to their forest homes.


During the breeding season, these sunbirds engage in a flurry of activity, with males displaying their brilliant throat patches to attract mates and both sexes participating in the construction of their delicate nests.

Similar Species

While unique in its genus, the Ruby-cheeked Sunbird can be confused with other sunbird species. However, its distinctive coloration and habitat preferences can aid in proper identification.

Diet and Feeding

Nectar forms the cornerstone of their diet, but they also pursue insects with zest, showcasing their adaptability and the crucial role they play in the ecosystem as pollinators.

Conservation status

Currently, the Ruby-cheeked Sunbird is classified as Least Concern by the IUCN, a testament to its resilience and the relative abundance of its populations across its range.

What Our Birders Say

Clean and easy to use
Really enjoying this app, it's clean and easy to use. I love the ease of being able to add those one-off birds without starting a whole checklist. I also like the social aspect, like the parts of my Facebook I like, without the ads and junk, just birds. Can't wait to see it become more populated.
Ideal Birdwatch Companion
Simply adds to the enjoyment of my birdwatching and helps me record what I’ve seen.
Really useful
Downloaded to give it a try, everything worked perfectly, recorded my first bird watching walk. Very impressed. Have already recommended to friends!

Birding and wellbeing app
Birda is an excellent platform to share your love of Birding and is a great tool of encouragement for a Birding Beginner like me. Birda has a very kind and supportive community of Birding enthusiasts. For me BIRDA is not only a BIRDING but also a WELLBEING App.
Just what birding needs
We need more fun in birding, for years it has had a reputation for being up tight and stuffy and only perused by retirees and anoraks. Birda helps change that perception and firmly brings birding into the 21st century! Fun, interactive while still contributing to science and conservation. If you aren’t on it, why not??
Wonderful App
Birda is my go to app for keeping records of my bird sightings and sessions. It has fantastic information which is great at aiding identification. With all the updates that are coming in the new year, this app is something special.

Fun way to add to your birdwatching experience
I enjoy watching birds in my backyard, but this app helped me really pay attention while on vacation this summer. It was fun to add new birds to my bird watching app.
