GRAY-CHEEKED THRUSH (Hylocichla alicise alicide) 

 The Gray-cheeked Thrush is a common transient in most 

 of our area, but is less common on Long Island. It passes 

 north the second half of May, and returns during the latter 

 part of September and early October. On one occasion I 

 have heard it sing. The greatest care should be used in 

 separating this species from the Olive-backed Thrush. The 

 plate in Doctor Chapman's Handbook is a better aid than 

 pages of detailed description. Sight records given below may 

 include BicknelPs Thrush.

BICKNELL' s THRUSH (Hylocichla alicise bicknelli) 

 BicknelPs Thrush is nothing[but a dwarf subspecies of the

 measurements. To be certainly identified it must be killed,
