 182 Bird - Lore

rupted task of incubation, circling about overhead and whistling loudly for ﬁfteen minutes or more before returning to alight on the nest.

Another bird, near whose ground-nest I had erected a blind, showed a similar inability to count above one. If one of two persons went away, leaving the other in the blind, the bird was apparently satisﬁed that all was wellt If, however, I entered the blind alone, an hour or more would pass before the bird's confidence in the situation was suﬁiciently restored to permit a return to her young,

This bird's nest was on the beach at the south end of the island, and, while studying her from my blind, I had an excellent opportunity to observe the Terns which were nesting there in numbers. At this time (July 5) the ﬁrst-born young were several days old. and the little fellows were run- ning about, apparently, wherever they pleased, attended by their parents. Several were seen to enter an inﬂowing creek, drink repeatedly of the salt— water and swim actively. in evident enjoyment of their natatorial powers, while the parents, who rarely if ever alight on the water, watched them from the shore. Possibly here was an explanation of the value to Terns of webbed toes. Functionless in the adult, they are of service to the young before the power of ﬂight is acquired.

Terns have ceased to nest on the once teeming sand-bars of Long Island. but two goodvsized colonies of these beautiful birds inhabit Gardi- ner‘s Island, and their presenCE adds immeasurably to the attractiveness of the beach-life. On the beach I also found the plaintive-voiced Piping Plover, a bird now so rare that in all my wanderings l have never encoun- tered it before. Only ten or twelve of these birds were seen, and search failed to reveal the eggs or young which they gave evidence of possessing. Let us hope this little band of survivors may escape the dangers of the migratory season. and with ever-increasing progeny return each year to the sheltering beaches of Gardiner's Islamlt
