Shorebirds are relatively common and easily seen and enjoyed. They are able to share their limited shore land habitat due to different adaptations. Probing for a morsel at one depth beneath the sand is successful to one and not another, because of the length of the bill. Access to a particular food source succeeds because of long legs.
Unfortunately, a significant number of these birds are threatened or endangered mostly because of loss of habitat and predation, compounded by long migrations and many different stopovers to feed and rest.
