Willow Thrush, Hylocichla 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, Hylocichla aliciae aliciae (Baird) 

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

 woods during migration. 



Olive-backed Thrush, Hylocichla ustulata sivainsoni 

 (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, Hylocichla 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.

 wr. Robins are numerous about the frequented portions of 

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

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

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