BIRDS OF DURHAM AND VICINITY.

Sylvania canadensis. Canadian Warbler. 686. 
If one searches lowland woods from the eighteenth to the twenty- 
fifth of May, he may form a passing acquaintance with the Canadian 
Warbler, otherwise he is not likely to meet it in this locality. At that 
time it is by no means rare. It is usually seen in company with other 
warblers that arrive at the same time, though apparently rather from a 
common impulse, than a real social instinct. While it is only a migrant 
here, one does not have to go more than thirty or forty miles toward 
the mountains to reach the outskirts of its breeding range. 
Setophaga ruticilla. American Redstart. 687. 
The Redstart is an abundant summer species, inhabiting thickets 
and woods, usually in the vicinity of water. Like the two preceding 
species, it is a fly-catching warbler, subsisting to a considerable extent 
upon flying insects. The males are often here by the tenth of May, 
and the females follow a few days later. The nest is a dainty cup- 
shaped affair, usually built in an upright fork of a small deciduous 
tree. Redstarts are generally all gone by the end of September, 
though I have on one occasion noticed an adult male on the fifth of 
October. 
Family MOTACILLID.'E. 
Anthus pensilvanicus. American Pipit. 697. 
Pipits, or Titlarks, are abundant during their migrations, but are 
most noticeable in autumn, when they are to be found on the salt 
marshes almost continually from September 15, the average date of 
their arrival, till the middle of October, Their maximum numbers 
are reached during the first week in October, when the first cold snap 
sends the main host toward a warmer climate. Although the smoothly 
mown marshes around Great Bay and along the seaboard are their 
favorite feeding grounds in this region, it is not uncommon to see 
them running about cornfields after the corn is cut and shocked. A 
specimen shot in a cornfield late in September had eaten eggs of some 
undetermined insect, a larval fly, a click beetle, and ten snout-beetles 
belonging to the family Otiorhyiichidce.
