Hi Stephen,

Fair questions but I would suggest that the first part of Q2 "were they 
immature birds" would have been better answered by you looking at the deceased, 
rather than asking the question of us who were not there. As for the other 
questions, it is hard to know how to answer them after the event. I wonder why 
it matters as to how these collisions occurred. I'd offer a general comment 
that nocturnal animals are more often road victims than diurnal animals.

I'd also raise the question as to whether if there is such mortality, if the 
urban area is a population sink (that is birds dispersing from bushland areas 
into the suburbs and dying on the roads there - thereby being a source of 
reduction of population, rather than increase). In which case this suggested 
increase may be illusory of an increase in abundance and is not a great trend. 
I point out, I am asking. I don't have any answers or information so don't 
quote me as if I do.
