On the Migration of North American Birds. 99 



arrival of the swans, geese and ducks gave certain indications of the 

 return of spring. On the 14th a robin appeared ; this bird is consid- 

 ered by the natives as an infallible precursor of warm weather;" and 

 Capt. Parry says " the snow bunting was the first precursor of 

 spring that appeared. When the well known notes of the whip- 

 poorwill, (Caprimulgus vociferus, and C. Carolinensis,) are heard, 

 the fanner is reminded that the time for the planting of com is at 

 hand. The fish hawk's return to the rivers of the north is regarded 



arrived. When

 the young as an evidence of the return of spring, and if we have in 

 common with them admired the beautiful sentiment of the poet, 



" Sweet bird thy bower is ever green, 

 Thy sky is ever clear; 



Thou hast no sorrow in thy song,

the inhabitants of the middle and northern states of our country 

 feel equally interested and pleased when they hear the soft and me-

Previous to a storm, the birds give indications of its approach. 

 Our vultures, in great numbers, rise in circles till they are almost 

 lost in the region of the clouds, the stormy petrels, (Thlassidroma 

 Wilsonii, Bon.) crowd in great numbers around vessels and follow 

 in their wake as if seeking the protection of man, the sea gulls and 

 terns make the shores reecho with their hoarse clamorous notes, 

 the loon, ( Colymbus glacialisj) is excessively restless and his screams 

 are heard at the distance of more than a mile and the barred owl, 

 (Strix ncbulosa,) utters his funeral cries even in the day. But when 

 fine weather is about to return the whole scene is changed, and every 

 hedge and copse and grove is rendered vocal and the whole feath- 

 ered tribe seem to rejoice at the prospect of the cessation of the storm 

 and the anticipation of bright skies and sunny days. 



But although our subject is far from being exhausted I am admon- 

 ished that it is time to bring these desultory remarks to a close. If 

 I shall have fortunately succeeded in throwing even a ray of light on 

 that which has hitherto appeared mysterious in nature ; or if I have 

 been enabled to awaken in a single mind a sentiment of admiration
