These bumper stickers were made for birders! Keep your fellow drivers informed of your intentions by labeling your car as being driven by a birder. A distracted birder is a lousy driver, ammirite? But if you always be birding, what else can you do?
Pick up a fun birdwatcher bumper sticker for the birder pal in your life.
If you brake for birds -- on the road, naturally, but also that weird looking raptor flying waaaay over there in the field -- you might be a birder. Let your freak birder flag fly, on your bumper, with a unique birder bumper sticker.
