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 untrequent- 
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 Mailards. It 
has not yet been found in Lorain county during my studies 
anywhere but on the lake. None have visited ovr 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.
