THE COMMON SWIFT.

sistent with the most perfect order, but in the autumn of 1830 
they were all repaired and roughcast , the swift's eyrie being care- 
fully protected from the hands of the renovator : the species has 
not, however, since tenanted the place. 
Swifts generally keep at such an altitude, that the vicinity of 
water is not enlivened by their presence as it is by that of some 
of the Hirundines, yet they may occasionally be seen flying over 
Belfast bay (particularly about the time of high-water), as well as 
skimming the surface of ponds and rivers. 
In and since 1842, 1 have remarked, that the borders of the bay 
are very frequently visited by great numbers of swifts, during the 
period of their stay, although they have no contiguous breeding- 
places. Their favourite haunt on the Down side is about Eich- 
mond Lodge, where trees — backed at some little distance by a 
high terraced bank — bound one side of the road ; between which, 
and the sea, at the opposite side, is a narrow belt of pasture, 
perhaps 300 yards in breadth. They are often as numerous here 
as swallows about an advantageous locality; — 150 to 200 being 
seen together. During the last few years when swallows were so 
scarce, their place here has been entirely monopolized by swifts. 
These birds visit the opposite side of the bay about Port William, 
&c., in similar numbers, and seem to be particularly fond of feed- 
ing above pasture-fields. I have no doubt that these large bodies 
move about as flocks to feed in company. Indeed, that such is 
the swift's habit may be inferred from the circumstance, of my 
having observed numbers feeding about the mountain-tops on one 
or two successive evenings, where on the following, though similar 
as to weather, not an individual would be seen. Over the town of 
Belfast, they were more numerous in 1842 than I had before 
known : — about forty individuals would occasionally appear career- 
ing together. 
Swifts have continued very numerous to this year, 1848, inclusive, 
and often frequent in great numbers the Eichmond Lodge “ beat." 
Here, on the 12th of July, 1846, I considered there might be 150, 
while above the road at Westbrook, less than a mile distant, simi- 
larly open to the bay at one side and bounded by trees on the
