PERCHING BIHDS. (ORDER PASSERES.) 



Flycatchers. (Family Tyrannid^.) 



Doubtless, every order of birds has had its day when, 

 if it was not a dominant t\^e, it was at least sufficiently 

 near it to be considered modern ; and as we review what 

 is known to us of that great series of feathered forms, 

 from the Arch?eopteryx to the Thrushes, we can real- 

 ize how varied has been the characteristic avifauna of 

 each succeeding epoch from the Jurassic period to the 

 present. 



Now has come the day of the order Passere,^^ the 

 Perching Birds ; here belong our Flycatchers, Orioles, 

 Jays, Sparrows and Finches, Yireos, Swallows, Warblers, 

 Wrens, Thrushes, and many others. A recent authority 

 classifies birds in thirty-four orders, but fully one half of
