NASHVILLE WARBLER — ORANGE-CROWNED WARBLER. 357 



HELMINTHOPHILA RUFICAPILLA (Wils.). 

 •-'<;i. Nashville Warbler. (()45) 



Above, olivo-grefii. l)iiglitt:r on I iv ruiiip, cliungiiig to pure ash on the 

 liead ; below, bright veUow, paler on the belly, olive-shaded on the sides ; 

 ■crown, with a more or less eoncealed chestnut patch ; lores and ring round the 

 ■eye, pale ; no .superciliary line. Fcinali' : — And autunnial specimens have the

H.\B. — Eastern Noi-th America lo tln^ I'lain.s, north to the l"ur Countries, 

 bi-eeding from the Northern United States northwai'(l ; Mexico in winter. 



Xe.st. on the ground, composed of withered leaves and sti-ips of bark, lined 

 with fine gra.ss, ])ine needles or hair.

Tlie Xaslnille ^^'al■bler, althotii^h an abundant .species, is not very 

 reguhir in his visits to this part of Ontario, being sometimes with us 

 in considerable numbers during the season of migration, and again 

 being ahiiost or altogether absent. Wlien they pass this way in the 

 spring, a few pairs usually remain over the summer with us, but the 

 greater number go on farther north. In the fall they are again seen 

 in limited numbers, working their way southward in company with 

 their young, which are distinguished by the absence of the crown 

 patch. In tliis part of Ontario, we never see so great a number of 

 Wai'blers in the fall as we do in spring. Either they are less con- 

 spicuous on accotmt of the time of their migration extending over a 

 longer ])eriod, or they have some other return route by which the 

 niajoritv find their wav south.
