YOUNG SEMIPALMATED PLOVER. 
95 
In size, this species conies nearest Q^havadvius curomcus ( pninov ^ 
of Europe, but in colour and all else most resembles C. hiaticula. 
On the coasts of New Jersey, this species arrives late in April, 
keeping then in flocks, and until late in May, when they depart in 
search of more northern climes. No instance is known of their 
breeding in the United States, but their flocks reappear periodi¬ 
cally in September, protracting their stay till the last of October. 
They run with rapidity, uttering a rather hissing short note, 
resembling the syllable thyk, thylc. It is a remarkable fact that 
these closely related species of Ring-Plovers, hardly cognizable 
at a distance by the eye, are at once detected by a practised ear, 
their note being so very different. For who could mistake the 
hissing voice of the present for the soft and musical tones of the 
Piping species, so happily compared by Wilson to a German flute. 
It is equally well known that the species of Europe differ also in 
this respect from each other, the true hiaticula having very nearly 
the same hissing voice as the Semipalmated, whilst the curonicus 
has a very melancholy cry, resembling Kirw ! Kirw !
