Cocos Flycatcher

Nesotriccus ridgwayi

The Cocos tyrannulet, scientifically known as Nesotriccus ridgwayi, is a diminutive avian species belonging to the tyrant flycatcher family, Tyrannidae. This petite bird, measuring a mere 13 centimeters in length, is cloaked in a subtle grey plumage and is distinguished by its elongated bill.

Distribution and Habitat

This species is a unique denizen of Cocos Island, situated off the coast of Costa Rica. The Cocos tyrannulet thrives in a variety of lush environments on the island, including subtropical or tropical moist lowland forests, swamps, montane forests, and moist shrublands.

Conservation Status

The Cocos tyrannulet is currently classified as Vulnerable. Its precarious status is attributed to the perils posed by invasive species, such as rats and feral cats that prey upon it, and pigs that ravage its habitat through their foraging activities. Although there is no concrete evidence of a population decline at present, the bird's extremely limited range is a cause for concern.

Easy to use and accurate
Love this app. It is easy to use and accurate, Their backup communication is really good. I noted a missing species. All through the process, I was kept informed about the progress in correcting the information. I now have the corrected, updated version. 😁 Thanks!

We've been waiting for an App like this
Excellent! We've been waiting for an app like this! Thank you! It would be nice if you could assign additional birds to sessions later!

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.

Great app for learning Birds
I’ve been using the app for a couple of months and love it....Someone said it’s like a real life Pokémon Go for birds. They’re not far off! It’s something that the family can do that gets you out and about. Well worth downloading no matter your age.

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.

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.
