118 BIRDS OF SWOPE PARK 



sr. If you are in some secluded part of the Park and think 

 you hear a Chipping Sparrow, better take a good look to see 

 if it is not a Worm-eating Warbler. The Worm-eating Warbler 

 is a fairly common bird along the lower part of Shiloh Hollow 

 and also along the shores of the Lake of the Woods. It does 

 not arrive until early May and leaves early in September. This 

 is one of the interesting and valuable birds that we may have 

 in this region only as long as we leave sections of the Park 

 in its undisturbed natural wildness.

 a very beautiful bird, that is all the more interesting because 

 of its peculiar, insect-like song. It arrives during the latter 

 part of April. 



Nashville W'arbler, Vermivora rubricapilla rubracapilla 

 (Wilson) tr. Nashville Warblers are found in considerable 

 numbers throughout the Park during migration, being espe-

 common among the red haw trees in the northwest corner of

Orange-crowned Warbler, Vermivora celata celata Say

 company with the Nashville Warbler and Tennessee Warbler. 

 It is not easily distinguished in the field from the Nashville 

 Warbler. 



Tennessee Warbler, Vermivora peregrina (Wilson) tr. 

 At about the first of May the red haw bushes in the northwest
