Some rare species found so far include Least Bittern (0/13, zero seen in the last 13 years, Norfolk County); Laughing Gull (2/13) found by Amanda Guercio at Sunnyside, Toronto; Mew Gull (4/13) in Brantford found by Sarah Lamond; White-winged Dove (3/13) in Coldwater found by Anthony Glenesk; Bay-breasted Warbler (2/13) in RK McMillan Park; and Black-headed Grosbeak (0/13) in Sawpit Bay, Algoma County. As usual after one week there are several holes to be filled in this winter list. These include Brant, Gray Partridge, Sharp-tailed Grouse, Dunlin, American Woodcock, Black-legged Kittiwake, Northern Hawk Owl, Boreal Owl, Black-backed Woodpecker, House Wren, Brown Thrasher, Pine Warbler, and Brewer's Blackbird. With the Christmas Bird Counts starting soon we will hopefully be filling in some of these gaps. If you haven't heard, the Ontario Field Ornithologists are running a Winter Birding Challenge. This challenge involves eBirding <https://ebird.org> a local area during the winter. More information about how to get involved and prizes can be found here: http://www.ofo.ca/winterbirding. Winter Listers can also keep track of what's being seen in the Ontario Birds Discord Server which can be found here: Discord <https://discord.gg/jQZtg4CwpR>. The winter list can be viewed at http://tinyurl.com/myyulvs. I try to update the spreadsheet every couple of days or whenever I hear of a new addition. Please let me know if you hear of a new addition or any other correction to the spreadsheet. Enjoy your CBC if you are participating, Todd Hagedorn
