Boletas Birdwatching Centre
As mentioned before, the best option for an organized trip in the most birding-productive areas of Spain. Just ask anyone who has been at Josele’s guesthouse in Sierra de Guara.

Don Roberson’s Creagrus pages
A comprehensive site about world bird and wildlife watching, trip reports and taxonomy. Includes an exhaustive list of bird families, and an interesting, if controversial, “Best birds of the world” list.

Vladimir Dinets
The word “adventure” is so misused nowadays that it seems to have lost much of its meaning. This page reminds you of what adventure travel really is. Especially interested in mammals, Vladimir has seen most of the world’s felines in the wild.

Nigel Blake
Now THIS is good bird photography. Good trip reports. Take a look at his Corncrake images, a bird I’ve never seen alive, that made me green with envy.

The most complete collection of world trip reports on the web. Excellent layout and content.

Fatbirder
The site to look for anything birding-related, worldwide.

The Canadian first lady of Digiscoping. Beautiful photos.
