396 OBSERVATIONS ON BIRDS. | 
notice of its habits and manners. I have never seen it but in the 
summer, between the months of May and September.—MARKWICK. 
SAND-MARTINS. 
March 23, 1788. A gentleman, who was this week on a visit at 
Waverley, took the opportunity of examining some of the holes in 
the sand-banks with which that district abounds. As these are un- 
doubtedly bored by bank-martins, and are the places where they 
avowedly breed, he was in hopes they might have slept there also, 
and that he might have surprised them just as they were awaking 
from their winter slumbers. When he had dug for some time he 
found the holes were horizontal and serpentine, as I had observed 
before ; and that the nests were deposited at the inner end, and 
had been occupied by broods in former summers, but no torpid 
birds were to be found. He opened and examined about a dozen 
holes. Another gentleman made the same search many years ago, 
with little success. 
These holes were in depth about two feet. 
March 21,1790. A single bank or sand-martin was seen hovering 
and playing round the sand-pit at Short Heath, where in the summer 
they abound. 
april 9, 1793. A sober hind assures us that this day, on Wish- 
hanger Common, between Hedleigh and Frinsham, he saw several 
blank-martins playing in and out, and hanging before some nest- 
holes in a sand-hill, where these birds usually nestle. 
The incident confirms my suspicions, that this species of hir- 
undo is to be seen first of any ; and gives great reason to suppose 
that they do not leave their wild haunts at all, but are secreted 
amidst the clefts and caverns of those abrupt cliffs, where they 
usually spend their summers. , 
The late severe weather considered, it is not very probable that 
these birds should have migrated so early from a tropical region, 
through all these: cutting winds and pinching frosts ; but it is easy 
to suppose that they may, like bats and flies, have been awakened 
by the influence of the sun, amidst their secret latebree, where they 
have spent the uncomfortable foodless months in a torpid state and 
the profoundest of slumbers. 
There is a large pond at Wishhanger, which induces these sand- 
martins to frequent that district. For I have ever remarked that 
they haunt near great waters, either rivers or lakes. —WHITE.
