Weather and Habitat Conditions 
Mild weather in late April and early May 
brought the mallards, pintails, and canvas- 
back into southern Manitoba earlier than last 
year. However, this mild weather gave way 
to a cold spell on May 3 when temperatures 
dropped to 19° at Brandon, Generally, cold 
and wet conditions prevailed thereafter and 
through the survey period with only a few 
days of sunshine occurring during the latter 
part of the period. Night temperatures 
dropped to 20° on May 23, which may have 
caused some damage to the late nesting 
species. On May 19 a snow storm resulted 
in a 6-inch covering of snow over the 
Riding Mountains and Dauphin Plains, 
The 1963 Manitoba water conditions were 
much improved over last year but remain 17 
percent below the 10-year average. April 
precipitation in Manitoba amounted to .66 
inches above the 73-year average and .9 
inches more than in April 1962. By the end 
of the survey period on May 24 the March- 
April-May precipitation exceeded the 73-year 
average for that period by .06 inches and, 
since some rain had fallen during the last 
week of May in Manitoba, the 3-month pre- 
cipitation total exceeded the long-termaver- 
age. The following table summarizes May 
temperatures and percent precipitation:
