These are the results of the 30th Woodhouse CBC held on Sunday December
18th 2016. The Woodhouse CBC is centred 7 km east of Simcoe, at the
crossroads of Highway 3 and Cockshut Road at Renton in Norfolk County and
roughly covers from Port Dover to Waterford and just west of Simcoe to east
of Jarvis.


Weather

The weather this year was certainly different from last year. Freezing rain
overnight made for treacherous driving and walking.

Overnight until nearly dawn there was freezing rain, then dry but cloudy
all day. Nearly all standing water was covered in ice. Temperatures varied
overnight between -1 and -9 with a daytime high of -1 for a short time
before it dropped again. The wind was mostly calm or light until the
afternoon when it increased slightly from the north west.


The freezing rain curtailed a lot of owling so owl numbers are lower than
normal this year.


A big thankyou to Madeline Wilson for hosting the roundup and to the
Norfolk Field Naturalists for sponsoring the Woodhouse CBC.
