Just some useful info for anyone who wants to travel there...
We stayed at the following, all of which I would recommend for their service and their friendliness (and in no particular order):
Black Sheep Inn
Mindo Gardens Lodge
Auberge Inn hostal
El Sol hostal, Cayambe
The Lonely Planet was pretty poor; maybe worth getting a different guidebook if possible. Other guides used: Ridgley & Tudor's A Field Guide to the birds of Ecuador [opens an Amazon link] (we only took vol. I out into the field, as that was plenty to be carrying.). We also took the Travellers Wildlife Guides: Ecuador [another Amazon link; sorry] by Pearson & Beletsky, which we found to be very jungle-oriented and pretty much useless for our purposes. Nice enough book though.
Finally, and very definitely not least was Danny, who guided us for the morning around Mindo: his company is Mindo Birding.
