An Unusual Nest ol the Cliil Swallow
Many years ago a colony of Clifi Swal- lows annually domiciled under the caves of a neighboring harn. Upon the introduc- tion ol the European House Sparrows. I noticed that they occupied the old nests he- lore the migrants arrived in spring, and annoyed the Swallows so that they left in despair. ln lqm and “)0! n colony at Clifl Swallows built under the eaves of Mr. Paul Fuller's harn. in Wyltott, N. 1., and in tgoz they httilt in a barn at Saddle River. In the latter place there was nothing in the shape of a projection under the caves. to sew: as a foundation for a nest, So the birds had some failures in building. One pair, with apparently more intelligence tltan the rest, took advantage ol a ledge which did duty as weather strip over the top edge or a wicket door, as here shown in a photograph by Mr. Winlretl Smith. After the nest was deserted it was taken duwn and presented to the American Museum of Natural History, The distance from the top of the ledge to ttnder eaves is about eighteen cht-s. This distance was reached by building acylittticr tube at clay worked up with short straw, and tilled with straw up to a height where it would just have room enough to build the nest on top; all of which was perfectly done. and the hirds had the happy satisfaction of rearing
their young on thia- ingenious t‘ltltxtrus'tion.
