78 BIRDS OF SWOPE PARK 



teresting. A later inspection showed that it was badly infected 

 with plant lice as well as with canker worms, and the birds 

 were busy ridding it of these pests. Watch them as they dart 

 from one leafy spray to another, or as they stretch their necks 

 to pick a morsel from overhead. Again, they are seen tipping 

 upside down to reach a worm on a leaf below. Now close your 

 eyes and listen; the twittering is incessant. They are singing 

 the freshness of the morning dew and blossoms and green 

 leaves. Some have truly wonderful flute-like voices that may 

 in different keys, yet they harmonize both in tones and with 

 be heard far away, others are soft and sweet and can be heard 

 only when the bird is near at hand. The effect is truly won- 

 derful. 



We who live in the suburbs and have a few trees in our 

 yards do not even need to go to the woods to see and hear the 

 Mayday performance. Fortunate, indeed, is one who at this 

 season of migration has a home with windows and a yard with 

 trees and shrubs; but he needs even more than this; he needs 

 the keen appreciation that alone can give charm to the pageant. 

 This appreciation is enhanced by an understanding of the 

 significance of the scene. The interest in the performance 

 grows by an acquaintance with the performers. 



After some practice, one may know which birds are on 

 hand merely by hearing their voices. He may be awakened in 

 the morning by a new note and can tell what new membc 

 have arrived during the night. How interesting to be on the 

 alert for new arrivals. What a disappointment if some favorite 

 happens to be delayed and arrives a few days late. During 

 this season the bird lover is consulting the time table daily.
