"The has been an increase in bird road casualties (especially Kestrels ). This is obviously due to new roads BUT ALL drivers are guilty."
Factually incorrect. Roads kill nothing. It's usually the vehicles and impact which do the damage.
"It is all well to make light of a call for raptor culls !!! But even birders in cars kill birds."
Factually incorrect also. It's usually the pressure wave from the front of the vehicle, and the back down-draft from the rear of the vehicle, the former pulling the bird into the latter, which usually creates the problem. This is usually created by high-sided vehicles, not cars. The aerodynamic design of most cars would lead this claim (But even birders in cars kill birds.) into the realm of highly improbable, especially relating to Kestrels and their associated road deaths.
Blackbirds and Pheasants flying low across roads is a different matter. As was the Waxwing which flew from my garden, straight into the side of a stationary double-decker bus. Stupid bird must have thought the bus was picking up passengers. Door was closed, oops!!
I witnessed 2 Owls killed on Monday, by the back-draft of box trailer lorries. The birds never came close to actually hitting the trailers.
Just wrong place at the wrong time.
I wonder if the Sparrowhawk was a hit-man for the mob.
American Robin which knew too much perhaps, see??
Never mind, if it had bred with one of ours, we could have had an "Alliance Robin"? Hey, new tick for the boys!
As for the Budgie, it belongs in the outback, or kept in safety, not in the wild in the U. K.
