I've recently discovered two pages (Prigogine's Nightjar
and Pallas's Leaf Warbler
) with content borrowed directly from wikipedia.
I just returned them to stubs, on the theory that 1. wikipedia does not mean "plagiarize this freely!" and 2. birdforum leadership set up our own wiki specifically for birders, not to duplicate the general encyclopedia at large.
If a wikipedia entry really is the best source on the web for some species, users should add an external link to it, not simply appropriate its entire text.
