4 88 THE SEMIPALMATED PLOVER. 



These Plovers migrate at night, preferably by moonlight; and, indeed 

 Killdeer may be regarded as an unquiet spirit on almost any moonlight night 

 in spring or fall. Most of the birds leave our borders for two or three 

 months in winter, but Rev. W. F. Henninger reports them as "very com- 

 mon" during that season in Pike and Scioto Counties.

General Range. Arctic and subarctic America, migrating south through 

 tropical America as far as Brazil, Peru and the Galapagos. 



Range in Ohio. "Not common migrant in spring, more abundant in the 

 fall" (Wheaton). Found regularly on the Lake Erie shore during fall migrations. 



THE Semipalmated Plover is a lesser Killdeer to appearance, but in 

 manner it is a much gentler bird, and, while with us at least, it realizes the 

 full value of the adage, "Silence is golden." Gentle and unsuspicious it 

 patters along the Lake Erie beach, following the retreating wave, or else 

 gleans from the mud-flats of river and pond, where chance finds it at earlv 

 morning. Only when startled from its quest does it utter a "soft mellow 

 whistle." It is not easily frightened, and if it has half a chance it will 

 scamper along the shore ahead of you, or even hide in the grass rather than 

 take to wing.
