The Meadowlark is another bird which migrates considerably by day. 

 Tlie immense, noisy tlooks of Fel)iU!>ry and .March are ahva.vs on the 

 move. Fift.v of these )»irds were seen as «>arl.v as January 21, t',)0::>, Hying 

 over due north at a height which made it necessary to use a powerful 

 tield-glass to identify them. 



This species, as well as most of the members of the family IrterUUn'. is 

 noted for its gregjirious haliits. That the different species should show 

 such habits Intvr sc. as do the swallows, is a more remarkable thing. 

 That this seems to l)e tlie case is the only logical conclusion to be drawn 

 from a study of local migration schedules. For instance, for a few days 

 previous to Maicli 21. l!»o;>, .Meadowlarks and (Jrackles, both resident 

 species were the only tctcr'nhr seen. On the 21st, however, these species 

 l)ecame auguniented in nund)ers while Kust.v Urackles, Redwings and 

 Cowbirds, not seen for several days before, again made their appearance 

 in considerable numbers. This famil.v migration is to be observed in the 

 IctfiiflfT at the time the s])ecies Ix'come abitndant and not at their tirst 

 arrival. The Orioles move together in the same way and l)ecome nutner- 

 ous at about the same time.

Common summer resident. a))undant and conspicuous during the 

 spring migration. Ai)ril 17 to August 2U. These dates are each one day 

 earlier than the recorded limits of its stay in the State. Six years out of 

 ten, this species arrived before the Baltimore Oriole. This is a somewhat 

 different proportion than the two out of fifteen obtained l)y A. W. Butler. 

 The difiference may be explained ))y a change in habit, as the dates of 

 arrival of the Orchard Oriole b(>fore that of its relative are all included 

 in the last seven years in which idtservations have been made at this 

 point. This change in date of arrival is probably correlated with the
