True, there are lots of those people who put a feeder up and watch only occasionally and I understand you're talking about these types.
However, there are also those backyard bird watchers who engage more intensely by spending quite a bit of money attracting birds to their yard and e-birding their patch totals daily. They'll also spend money on a pair or two of binoculars. These types probably bird watch more than I do since I only have the weekends, days off work and sometimes find time before work or on lunch to go to a local spot. So, I wouldn't discount "backyard birders" since some are just as passionate about their hobby...they just don't travel to see birds.
