Thought this was pretty amazing. I’ve seen the clip of the crows using the traffic lights before, but this is something else. Really fascinating.
P.S: I’m really sick of video sites that don’t make it easy to embed videos using SWFObject. Flashvars are awful -_- … Now everyone on IE gets the stupid Eolas flash prompt… Other bloggers will know what I mean…
Picked this up from a NewScientist article.
Ground-living vertebrates have declined by 25%, with most of the slump occurring since 1980. Marine species held fairly steady until the late 1990s before falling sharply to give an overall drop of 28%. Freshwater species have decreased by 25%, primarily since the late 1980s.
Loh says the most dramatic declines have been observed in the tropics. Tropical ground-living species have seen an average population drop of 46%, while their temperate cousins have shown no overall change.
They don’t seem to be 100% sure on the numbers, but they could possibly even be conservative.
