north. Their breeding habits probably are much the 
same, and what the birds do at such times and in 
that region has best been described by Seebohm in 
his classic little volumes, ‘‘Siberia in Europe” and 
“ Siberia in Asia.” Inthe tundras he found the sand- 
pipers nesting, and scattered through the pleasant 
pages of these charming books we get glimpses of 
the life of these birds, that, so far as we know them 
at home, are visitors only. 
Many of these sand-pipers that are fairly common 
to our sea-coast marshes are birds of the interior. 
Dr. Warren records them as occurring at Erie Bay 
in Pennsylvania, and in the far West many are very 
abundant; much more so, indeed, than in our Eastern 
districts. 
Of the inland species, the Spotted Sand-piper, known 
so generally as the ‘“ Teeter-Tiltup,” from its quaint 
way of bobbing both head and tail as it walks, de- 
serves especial mention. 
Wilson’s account is as follows: 
«This very common species arrives in Pennsylvania about the twen- 
tieth of April, making its first appearance along the shores of our 
large rivers, and, as the season advances, tracing the courses of our 
creeks and streams towards the interior. Along the rivers Schuylkill 
and Delaware and their tributary waters they are in great abundance 
during the summer. 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 the fences, along the rails, or in the 
water, this motion seems continual; even the young, as soon as they 
are freed from the shell, run about constantly wagging the tail. 
About the middle of May they resort to the adioining cornfields to 
breed.” 
This sand-piper is the only one that ventures quite
