Insects[edit]
A recent study showed that insects, too, are prone to a very high risk of roadkill incidence.[15] Research showed interesting patterns in insect roadkills in relation to the vehicle density.
In 2003-2004, the Royal Society for the Protection of Birds investigated anecdotal reports of declining insect populations in the UK by asking drivers to affix a postcard-sized PVC rectangle, called a "splatometer", to the front of their cars.[16] Almost 40,000 drivers took part, and the results found one squashed insect for every 5 miles (8.0 km) driven. This contrasts with 30 years ago when cars were covered more completely with insects, supporting the idea that insect numbers had waned.[17]
In 2011, Dutch biologist Arnold van Vliet coordinated a similar study of insect deaths on car license plates. He found two insects killed on the license-plate area for every 6.2 miles (10.0 km) driven. This implies about 1.6 trillion insect deaths by cars per year in the Netherlands, and about 32.5 trillion deaths in the United States if the figures are extrapolated there.[18]

Feeding[edit]
Vultures rarely attack healthy animals, but may kill the wounded or sick. When a carcass has too thick a hide for its beak to open, it waits for a larger scavenger to eat first.[4] Vast numbers have been seen upon battlefields. They gorge themselves when prey is abundant, until their crops bulge, and sit, sleepy or half torpid, to digest their food. These birds do not carry food to their young in their claws, but disgorge it from their crops.
Vultures are of great value as scavengers, especially in hot regions. Vulture stomach acid is exceptionally corrosive, allowing them to safely digest putrid carcasses infected with botulinum toxin, hog cholera bacteria, and anthrax bacteria that would be lethal to other scavengers.[5] New World vultures often vomit when threatened or approached. Contrary to some accounts, they do not "projectile vomit" on their attacker as a deliberate defense, but it does lighten their stomach load to make take-off easier, and the vomited meal residue may distract a predator, allowing the bird to escape.[6]
New World vultures also urinate straight down their legs; the uric acid kills bacteria accumulated from walking through carcasses, and also acts as evaporative cooling
