174 BIRDS OF THE PUBLIC GARDEN 



92. MARYLAND YELLOW-THROAT 



Geothlypis trichas 



The Maryland Yellow-throat is a quite 

 common visitant to the Garden. Its earliest 

 appearance in the nine years was on May 

 3> I95 > when three male birds were seen. 

 The preceding year the first bird appeared 

 on May 4, a male bird in song. In other 

 years the time of arrival has been between 

 May 9 and 14. The period of migration has 

 variously covered from ten to twenty-four 

 days, the latter period in 1905. In 1907 it 

 covered seventeen days, May 13 to 29; in 

 1908, twenty days, May 10 to 29. Usually 

 the last birds of the species have passed on 

 May 22 to 26. Five or six Yellow-throats 

 have often been noted upon the same day, 

 and such little flocks have sometimes re- 

 mained several days. The song from time 

 to time has been heard. Following their 

 usual habit, the Yellow-throats are com- 

 monly in the larger individual shrubs or 

 the shrub-groups, rather than in the trees, 

 but sometimes they are in the larger trees
