1) It seems bats die from the low air pressure around wind turbines.

  The Calgary team collected carcasses of hoary and silver-haired bats
  killed at a wind farm in south-western Alberta.
  
  Examinations showed that fewer than half had external injuries that could
  have been caused by collision.
  
  But about 90% had internal haemorrhaging, most notably in the chest
  cavity, a condition that puts pressure on the lung and can be fatal.
  
  The idea is that the pressure around a rotating turbine blade is lower
  than in the surrounding air. A bat flying into the low-pressure zone
  finds its lungs suddenly expanding, bursting capillaries in the
  surrounding tissue which then becomes flooded with blood.

2) Cattle tend to align north-south.

  Have you ever noticed that herds of grazing animals all face the same
  way?
  
  Images from Google Earth have confirmed that cattle tend to align their
  bodies in a north-south direction.
  
  Wild deer also display this behaviour - a phenomenon that has apparently
  gone unnoticed by herdsmen and hunters for thousands of years.
  
  ...
  
  The researchers surveyed Google Earth images of 8,510 grazing and resting
  cattle in 308 pasture plains across the globe.
  
  ...
  
  The researchers also recorded the body positions of 2,974 wild deer in
  277 locations across the Czech Republic.
  
  Their fieldwork revealed that the majority of grazing and resting deer
  face northward. About one-third of the deer faced southward.
