tance along the outer wing-feather, it does not give the im- 

 pression of a well-defined tip, as in the Kittiwake. The 

 immature Kittiwake is readily told by the black-tipped tail, 

 and by the broad black edging along the forward portion of 

 the wing.

 often longer than the others (over six inches longer than the 

 others in the adult Long-tailed Jaeger) ; a conspicuous whitish 

 band across the under sides of the wings near the tip.

 the freshly-caught fish dropped from the bill. To see Jae- 

 gers, one should watch the terns as they migrate along the 

 coast in late summer ; or, better still, sail with some fish-

Jaegers appear in almost every possible plumage, but

 bird that they pursue. The commonest species off our const,
