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.
Anna's hummingbird dives at nearly twice the speed relative to its body size than the peregrine falcon, which flies at a maximum velocity of about 200 body lengths per second. The hummingbird is also faster than the swallow, which dives from high-altitude migratory flights at a speed of about 350 body lengths per second.
