September 29th

September 30th was a rain out, and no banders will be present at Ruthven on October 1st, which will likely also be a rain out.

September 29th
A cold front originating in the north and expected to hit our area by midweek has encouraged migrants to (finally) begin moving. Amongst the catch today was a rather portly Blackpoll Warbler that tipped the scales at 19.5g! The average for most of the Blackpolls we’ve been catching is about 13.0g.

The mosquito situation continues to be ludicrous. A cold snap should reduce their numbers but in the meantime I think we should invest in a mobile blood transfusion unit for the banders.
