slough about 50 yards away. Here is the
description as I r ecorded it.
The head and neck were brownish-
rusty, not nearly so bright rusty as cin-
namon teal but more brownish. It had a
thick white line above the eye, which
tapered down to a very thin line as it
extended towards the back of the head;
the two lines almost met. The chest was
brown with small round spots very
much like a male blue-winged teal, also
the flanks were this colour. It had a
large medium gray patch on the sides,
about the same size as the chestnut
patch on the shoulder. I d on't remember
other details about the back or wings. It
seemed to be exactly the same size as
the blue-winged teal and was found in
the same habitat of shallow sloughs.
The weather conditions on that day
were extremely windy and dusty, with
limited visibility. It also became cloudy
as the wind shifted from west to north-
west. Under these conditions it was
hard to get good pictures, but it did not
affect the use of binoculars. My binocu-
lars were 7-15 x 35 zoom, my camera
lens a 300 mm. The location was about
five miles north of Taber and three
miles east. This is located in square No.
VL22, in the Medicine Hat region. I was
able to observe the bird for several min-
utes.
This is all that I c an think of to
report. I w ill send you a picture when
they are ready. Thanks for helping me
identify the bird, since I w ould have
gone crazy not knowing what it was.
Hope you have more good luck with the Figure 1.
