127 PIED WAGTAILS counted in the roost tree outside of Waterstones yesterday (14/12/2009) afternoon from c.15:58-c.16:20 making an average of 5.8 birds entering the roost per minute. Both the count and the average are down on last time, despite it probably being colder. I could have sworn that some birds that flew onto the rooves to wait to enter the roost didn't enter in the end (I count birds as they enter the tree only), so there were probably more roosting elsewhere?
