From the field

Birds from the Himalayas to the Western Ghats, each photograph with the couplet it carries

Kalij Pheasant, The Garhwal Himalayas — Kalij Pheasant
The Garhwal Himalayas
His face is chilli-red, his back a midnight blue;
she wears the forest floor — and the forest wears her too.

Green-tailed Sunbird, The Garhwal Himalayas — Green-tailed Sunbird
The Garhwal Himalayas
Puffed into a ball of gold against the cold,
he guards his patch of blossom, tiny and bold.

Blue-throated Blue Flycatcher, Thattekad, Kerala — Blue-throated Blue Flycatcher
Thattekad, Kerala
His throat is blue where his cousin’s is flame;
he winters here, then goes back the way he came.

Indian Pond-Heron, Bharatpur, Rajasthan — Indian Pond-Heron
Bharatpur, Rajasthan
A clod of brown on the bank — until it unfolds
into a white that no muddy bank ever holds.

What it actually does

And, as importantly, what it declines to do

3,751 species

1,092 of them recorded in the Indian subcontinent. Tell it where you were shooting and it stops offering you American birds.

It says when it doesn't know

Anything it isn't confident about goes to _Uncertain rather than being guessed at. Measured on 400 photographs of 20 species it has never seen, the strictest of the three settings keeps 92% of them out of your species folders.

Nothing leaves your Mac

Identification runs on Apple's on-device machine learning. There is no server to send photographs to, which is also why it works in the field with no signal.

The trial counts birds

Forty frames of the same bird spend one of your ten free species, not forty. Paid photographs are counted per frame, and a RAW and JPEG of one shot count as one.

Photographs

Bought outright. No subscription, and they never expire

Try it first: 10 species free, no card and no account. Ten different birds — a burst of forty frames of one bird spends one of the ten, not forty.

A licence covers one machine, and you can move it to another whenever you like from inside the app. A photograph is one press of the shutter, so 500 means 500. A RAW and a JPEG of the same shot count as one; a photograph the app cannot confidently name still counts, because the work of looking at it was done either way.
