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, 1905, 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
