It is simply the angle that the wing of the bird is to the incoming air force. This term is used when the birds are gliding or not flapping their wings. A change in this angle can cause the bird to be either more streamlined, cause lift, drag or even descent.
The angle of attack is an aerodynamic term which refers to the angle between the mean wing chord of the airfoil and the direction of airflow. This is different from the pitch angle of the aircraft in that the pitch angle refers to the aircrafts position in relation to the horizon, whereas angle of attack refers to the aircrafts angle in relation to airflow.
An acute angle is a geometry term that refers to an angle that is less than 90 degrees. If it is 90 degrees it is a right angle, and if it is more than 90 it is obtuse.

REFLEX is actually an angle which is known as REFLEX ANGLE that is only an angle that is between 180 degrees and 360 degrees.
the angle the theoretical incident ray makes with the final refracted ray

a supplementary angle adds up to 180 degrees
why is the solar angle a term that refers to the
Paroxysmal means relating to a sudden attack or worsening.
There is no angle to refer to in this question. Therefore, no answer can be given as to which term best describes the angle referred to.
Time Attack is a commonly used term in Japan for individual time trial events for motor vehicles that involve a vehicle running around the circuit instead of a qualifying lap.
The term angle of deviation is used in reference to a prism.
