Terms of use

Who we are

Editheria Nature Books, an independent natural-history publisher founded in 2025 by Lucero E. Legarda-Solarte and Luis Arturo Román Luzuriaga. It trades as a sole proprietorship in Ecuador, and Ecuadorian law governs these terms. Write to roman@editheriabooks.com.

What this site is

A description of our books, and a page that sends two free companion files to readers who ask for them. Nothing is sold here. Purchases happen at Amazon and other retailers, under their own terms, and any question about an order, a delivery or a refund belongs to the retailer you bought from.

The free files

The companion atlas and the print-at-home postcard are yours to keep, print and use for your own birding, and to show to anyone you like. Please do not sell them, republish them, or pass them off as your own work. If you want to use a page in a talk, a class or an article, write to us — the answer is usually yes.

Your copy of the book

Buying the book buys you the book. Write in it, take it into the rain, quote it, lend it. What it does not buy is the right to copy it, scan it, or redistribute the plates and maps separately.

Artwork and copyright

Every illustration, map, chart and page design in our books and on this site is original work owned by Editheria Nature Books or licensed to it by its authors. The watercolour plates are Miles McMullan's. The distribution maps are built from published observation data and are our own cartography. None of it may be reproduced commercially without written permission.

The newsletter

You subscribe by ticking a box, and you leave by clicking one link. We will not add you to the list any other way, and we will not use your address for anything you did not agree to.

Links to other sites

We link to Amazon, to eBird and to conservation organisations. Those sites are not ours and we are not responsible for what they do with your visit or how they change over time. The QR codes inside the atlas point to eBird species pages for exactly this reason: the data belongs there and stays current there.

Field information

This is the clause that matters most, so it is written plainly. The viewing sites, seasonal windows, difficulty ratings and range maps in our books reflect the best observation data available when the book went to press. Birds move, seasons shift, access to land changes and conservation status is revised. A site that was open last year may be closed, and a species recorded reliably in one decade may not be in the next.

Use the book to plan, and then check current conditions yourself: land access, permits, weather, road conditions and local advice. Going into the field is your decision and your risk, and we cannot be responsible for what happens on a trip our pages helped you plan.

What we can promise is the other half of that bargain. Every volume in The Field Book of… is written to be revised: as new observation data arrives, as ranges shift and as conservation status is reassessed, those changes go into an updated edition rather than being left to age on the page. Tell us what you found and what you did not, and it feeds the next one.

What we cannot promise

We take accuracy seriously — the accounts were reviewed by ornithologists before publication — but we cannot promise the site or the files will be free of errors, or always available. If you find a mistake, tell us: corrections go into the next edition and we would rather know.

Changes

If these terms change we update the date above. Material changes are announced in the newsletter.
