Nest cameras - surveys
Bird nest web cameras seem to abound. After a check by Google for osprey nest cams that turned up some twenty (relevant) hits on the first few pages, it seemed that somebody must have felt the need of an inventory before me.
Here are rather thorough listings for about 100 bird specieshttp://www.viewbirds.com/
with i a 41 osprey sites. Web page last revised 11th May 2012
Below is the introduction from the Viewbirds nest camera page:
"The sites listed below feature live webcam coverage, updated videos, and/or updated photographs of nesting birds. You can follow the efforts of the parents and the progress of the young by periodically visiting these nest sites.
Bird species are in taxonomic order and sites are arranged alphabetically by locality. An asterisk (*) indicates that a site is currently active, and a degree symbol (º) indicates that a site works best with Internet Explorer. To observe bird cams focused on feeders in a variety of countries, please go to the Bird Feeder Webcams site
." (my underlining)
I checked the entries for a few bird species for whom I know of cameras: the Looduskalender ones and some Swedish sites. Results were reasonably correct and updated, and in general a surprisingly large collection also of European (non-English?) sites.
For the more far-away sources: there are 2 Japanese cameras, some Australian ones. What about Russia (unp, other members ...?).
EDIT: The View Birds Nests site is actually already in this topic (and in Useful tools), nested in as a "useful resource" in Fatbirder posted by Maertha
. But it deserves a mention on its own, for the clear and comprehensive listing.
