Counting method: I counted 5 rows of cable where they roost and found an average of ~50 birds in a single cable stretch, and then counted the number of cable of similar length used for strecth (84 cable). 84 x 50 = 4200 individual, with addition of 185 indivdual I counted perching on building ledge. This number is also greatly underestimated as there are a significant number of the bird roosting on buildings side that are not visible from the road.
