The Tilt-up, as this Sandpiper is universally known in this section, 

 arrives in Pennsylvania about the middle of April, sometimes even 

 earlier. It is common and indigenous. The nest is placed on the 

 ground in a grass field, sometimes in a grain-field, or on the sandy 

 bank near streams and ponds, along which these birds are commonly 

 found industriously seeking their hidden prey. Wilson very properly 

 says : "■ This species is as remarkable for perpetually wagging the tail 

 as some others are for nodding the head; for, whether running on the 

 ground, or on fences, along the rails, or in the water, this motion seems 

 continual; even the young, soon after they are freed from the shell, 

 run about constantly wagging the tail.'' When you approach the 

 eggs or young the old birds manifest great concern. They flutter 

 along the ground as if injured, and should you follow and attempt to 

 catch them they will lead you to a considerable distance from their 

 treasures before flying off. Wilson mentions the following instance, 

 which shows the great solicitude which the female has for her young:
