That's bullshit and you know it. I hate when people rag on wikipedia for not being a reliable source
Look at this: http://www.nature.com/nature/journal/v438/n7070/full/438900a.html
Guess where I pulled that site from? The bottom of a wikipedia page
If you wanted a reliable source, just scroll down to the bottom of any wiki page and find the source you are looking for. Most pages on wikipedia are just a conglomeration of sources.
Here is a link to a "reliable" source: http://www.britannica.com/EBchecked/topic/125544/collective-behaviour
(Which no doubt wikipedia cites)
Granted, there are some straw mans out there but they are far and few
