Chicago IL is called the windy city, December to March the average wind speed is 6 mph, however Boston MA is windier, December to March the average wind speed is 7 mph.
For my town of Walpole the next 4 days the wind is going to be 12-15 mph and then after that it drops to 10 mph for the next 10 days, to me that really affects bird photography not to mention with the temps in the mid 30's the wind chill cuts right through you.
It seems to be that the birds don't fly unless they have to.
What it is like in your area

Even perched they had trouble, I posted a few with feathers blown everywhere from my garden in the 'post your birds' thread.
