In the ICD-10, the symptoms of hyperkinetic disorder are analogous to ADHD in the DSM-5. When a conduct disorder (as defined by ICD-10) is present, the condition is referred to as hyperkinetic conduct disorder. Otherwise, the disorder is classified as disturbance of activity and attention, other hyperkinetic disorders or hyperkinetic disorders, unspecified.
It depends on whether you are talking about an African or European swallow. The airspeed velocity of an unladen swallow is roughly 11 meters per second, or 24 miles per hour*, beating its wings 7-9 times per second (rather than 43). But please note that a 5 ounce bird cannot carry a one pound coconut.
Sent in by William S. Blackwell, Bedworth, Warwickshire. The peregrine falcon is arguably the fastest bird in the sky. Its streamlined body, powerful muscles and swept-back wing shape are perfect for fast flight. During level flight, with motion generated by wing-beats alone, they can reach speeds between 40-60 mph.This is one of the fastest known speeds for level flight with only a few species of duck, wader and pigeon known to reach similar speeds in comparable flight.uring level flight, with motion generated by wing-beats alone, they can reach speeds between 40-60 mph.
