Hummingbirds

Hummingbirds, small, vibrant birds of the family Trochilidae, are native to the Americas, ranging from Alaska to Tierra del Fuego, with the highest diversity near the equator. Their size varies from the tiny 5 cm bee hummingbird, weighing less than 2 g, to the largest species at 23 cm and weighing up to 24 g. Known for the humming noise made by their rapidly flapping wings, they can hover in mid-air with wing beats from 12 to 80 times per second and achieve speeds over 54 km/h. Splitting from swifts about 42 million years ago, hummingbirds have a fossil-recorded ancestor in South America 22 million years ago. Hummingbirds feed mainly on nectar but also eat insects and spiders. Remarkably, they possess the highest metabolism relative to their size of any warm-blooded animal and can enter a hibernation-like state called torpor to conserve energy.

The best bird logging app

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!

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.

Work together with community

Been loving using this app to log my bird sightings and work together with community members to identify different birds. I've already learned a lot since I started about a month ago!

Fantastic App

This is a really lovely app, for everyone interested in birds - from newbies to old hands. There is a very friendly feel to the community and you will genuinely learn a lot as you record your sightings and photos. There are lots of badges and competitions to keep you engaged, and a host of really useful features.

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??
