I'm curious what companies mean when they market binoculars labelled "birding binoculars". Examples are Nikon's 8x32 SE or Swarovski EL 8x32. How are these different from Canon 10x42 (one I use for astronomy) or a Fujinon 7x50? I am guessing birding binoculars have a wide field coverage and have better color rendition.
They are usually 8x, so you get the wide field.
8x model birding
10x model of the very same, hunting 
What Tero said though personally I've always used 10x for both but most birders seem to prefer 8x.
