Ottawa Duck Club 2011 Statistics

Had a look at the late summer edition of The Nest Box, newsletter of the Ottawa Duck Club. Main activity of the club is the installation of nest boxes for ducks (Wood Ducks and Hooded Mergansers mostly). They keep stats on 61 boxes (about one-third of the boxes they have in place).

This year the boxes held an average of 10.4 eggs, close to the nine-year average of 10.8. 377 Wood Duck eggs were laid and 265 hatched (71%). 299 Merganser eggs were laid and 191 hatched (64%). If the other boxes did as well, that would be almost 2,000 eggs per year.

There has been a steady increase in the number of Merganser eggs laid each year. It is not known if this is at the expense of the Wood Ducks.

The volunteer club operates in the wildlife sanctuary on the military training ground and rifle range just west of Ottawa. Website is at http://www.ottawaduckclub.com
