Just thought I'd share some websites I use as part of my hobby. They are mainly UK-specific, but could be of interest to overseas birders:
It costs to get the detailed content, but they have a free sightings list and weekly newsletter. Plenty of links to other sites as well.
"The" birding website. Plenty of identification help, including recordings of calls and videos of birds in motion. Not very interactive, though.
More specialist website, home of the UK bird surveys. Site seems broken at the moment - homepage is blank, as are several others. Link given is to BBS, you can explore from there.
New to me, aimed at a mix of amateurs and pros - forums and advice, but the biggie is uploading photos of your sightings with a facility for members to agree with your identification or discuss it. Also has sections to cover all other aspects of wildlife, even fungi and lichens. I've just joined - care to guess my user name? Update:
SITE IS NOW LIVE! Go see.
Hope these are of interest - maybe you'd like to share sites that are as useful in your area or country?
