Christmas Bird Count 2009: O’Shaughnessy Reservoir

Count Summary

Number of Party Hours: 69.5
Species reported on count date: 76

Our actual species on count day were 73, plus 3 species for count week for a total of 76 species.

The weather was very cold weather for counters and birds alike, with most water areas frozen. We feel that this limited both the number of species and number of individuals. On to next year!

It was special to be able to count a 60 acre private property as an extra area in our circle. Doing so produced two species for the day not seen anywhere else in the circle.

We also noted very high numbers of Horned Larks due to cold and snow cover. As an added treat, we found Lapland Longspurs and two Snow Buntings.
