than does the Brown Thrasher, in fact they may be heard late 

 in the evening for the greater part of the summer. 



Willow Thrush, Hjlocichla fuscescens salicicola Ridge- 

 way tr. This Thrush is occasionally found in the woods dur- 

 ing early May and again in the autumn from the middle of 

 September to mid October. 



Gray-cheeked Thrush, Hjlocichla aliciae aliciae (Band) 

 tr. Quite a few of these Thrushes pass quietly through our 

 woods during migration. 



Olive-backed Thrush, Hjlocichla ustulata swainsoni 

 (Tschudi) tr. Occasionally bird lovers have an opportunity 

 of hearing this fine singer as it passes through and stops to 

 feast on the fruits and insects of our woods. Some of them 

 loiter along until the mating impulse stirs the males to begin 

 singing. They are still to be found here as late as June.

Hermit Thrush, Hjlocichla guttata pallasi (Cabanis) tr. 

 Hermit Thrushes are quiet and undemonstrative as they pass 

 through the Park during their migrations. A few may be 

 found in the woods during the first half of April and again 

 in October. 



Robin, Planesticus migratorius migratorius (Linn) sr and 

 wr. Robins are numerous about the frequented portions of 

 the Park, such as the Shelter House, Refectory and the picnic 

 grounds. During migration, great flocks may be found in 

 any part of the Park. This bird is known and loved by every- 

 body, yet it can hardly compare with numbers of others to be 

 found in the Park, either in usefulness, beauty or song.
