flight refers to a group of flying birds, ie a flight of swallows
Mainly flying insects, which are caught in flight.
the function of a tail is to lift its body and to increase the speed of flight
The most important flight muscles are the pectorals, which correspond to the muscles of your chest :)
After the pectoralis major, the next most important muscle in the birds is triceps. It is highly developed muscle in birds and used to extend the wings.
humming birds are small in size
An analogous organ is a structure in different species that serves the same function but does not share a common evolutionary origin. For example, the wings of birds and insects are analogous organs as they both serve the function of flight but evolved independently.
Flight (n) [...] 2. a group of creatures or objects flying together, in particular: a flock or large body of birds or insects in the air, esp. when migrating.
There are carnivores and herbivores in both birds and insects.
