ANSERES. ■ 39 



This once abundant duck is now common only locally and 

 there only occasionally. It has become wary and hard to ap- 

 proach. In Lorain county I have seen only single individ- 

 uals and two together, and they on the smaller unfrequent- 

 ed ponds. Lately several have formed the habit of visiting 

 our water-works reservoir, in spite of the fact that it lies 

 well within the town. If it breeds within the state now there 

 is no mention of that fact in the reports received. Dr. Lang- 

 don mentions its breeding in Ottawa county. 



Migration dates for the spring movements fall within 

 the third week of March for southern Ohio, but almost a 

 month later for Oberlin. The southward movement occurs 

 late in October.

This teal is reported as a common migrant across the 

 state. It is the earlier of the two teals, arriving with the 

 Mallards and other early ducks. I have seen several indi- 

 viduals of this species migrating in flocks of Mallards. It 

 has not yet been found in Lorain county during my studies 

 anywhere but on the lake. None have visited oi^r water- 

 works reservoir.

This is a common duck locally during the migrations, but 

 it is clearly less common than during Dr. Wheaton's time. 

 It may be found on the smaller streams and ponds as well 

 as on the larger rivers and lakes. In Lorain county I have 

 found it only on the small ponds in twos and threes or 

 singly. Flocks are sometimes seen passing northward.
