Midgic transect: Start at road intersection 1-1/4 miles south-~ 
southwest of Midgic Station; east at Upper Sackville post offices stop 
one mile west of Chignecto Dry Dock. Total, 7 miles, 15 stops. 
Midgic study area: Two miles northeast of Upper Sackville at 
Canadian National Railway crossing (= stop number 3 on Midgic transect). 
Jolicure study area: Northeast corner of Front Lake Marsh, 
3/4 mile by road northwest of Jolicure (not on any transect). 
The trmsects were normally covered from north to south, 
Comparisons with Manitoulin Island Conditions 
Investigations in the Sackville area of New Brunswick confirmed 
the conclusions of the 1952 studies on Manitoulin Island, Ontario. 
Winnowing was consistent enough to serve as a population index only 
during a period of about half an hour in the evening and half an hour 
in the early morning. 
The Manitoulin and the Sackville areas have exactly the same 
latitude. One of the Sackville routes actually cut across the latitude 
where the Manitoulin studies were made (5° 5h'), and the other two 
routes were within ten miles of the same latitude. Therefore, in com- 
paring the tw areas no correction need be made for geographical posi- 
tion with respect to sun position, as long as time intervals are com- 
puted from local sunrise and sunset. time. The difference in elevation 
of 580 feet is not considered to have any more significant effect than 
the local differences in weather conditions. 
The fact that both Manitoulin Island and Sackville areas are 
encompassed within the same life zone, having a pine-hemlock-northern 
hardwood climax, wuld seem to indicate a similarity of climatic 
factors important to life processes. However, there may be some 
differences which conceivably could effect the behavior of snipe such 
ag an average greater amount of fog in the maritime Sackville area © 
which should be taken into consideration. 
Time of Day 
Table 23 shows a comparison between the times of starting and 
stopping of the periods of peak winnowing in the evening and in the 
morning, for both the Ontario and the New Brunswick areas. Observa- 
tions made under rainy, windy or other particularly. unfavorable con- 
ditions have been omitted from the table. There is still considerable 
variation from day to day as shown by the standard deviations, but no 
significant difference in winnowing time between the two areas is 
indicated. Therefore, the times of peak winnowing indicated here may
