Essential Birding Websites (1 Viewer)

How about an index of the best websites about birds and birding? Anybody got any recommendations for sites that birders should know about? I'll kick of with a few of my own...

BirdForum
Of course

Internet Bord Collection
Images, videos etc. of "92.53%" of worlds bird species

Wikipedia
Great website anyway, great for bird info too. All aspects are covered, from individual species accounts to evolution and taxonomy to migration studies to the history of bird watching and more.

Birdtrack and E-Bird
Make your birding count!

Bubo
Simple world listing

Flikr
A huge amount of bird pics, drawings and groups

Birdguides
A fair amount of useful stuff, even if you don't subscribe

The BTO Youtube Channel
ID videos, survey tutorials and etc. Growing all the time

In Birdforum: the Opus section with pages on every bird and a lot of locations, and don't forget the Resources section (and yes, I am not impartial regarding this )

More in depth section on birds in the Neotropics: http://neotropical.birds.cornell.edu/portal/home (unfortunately not fully written for a lot of species)

Ebird for submitting your observations and for figuring our where birds are seen: http://ebird.org/content/ebird/
