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

 if it was not a dominant type, 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 Arehgeopteryx 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. 



]S"ow has come the day of the order Passeres, the 

 Perching Birds ; here belong our Flycatchers, Orioles,

 Wrens, Thrushes, and many others. A recent authority 

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