An animal tag configured to monitor animal behavior, the animal tag comprising: a first set of sensors configured to repeatedly produce a first amount of data representing a movement vector (M xyz) of the animal tag relative to a fix reference frame (x, y, z), wherein the first set of sensors comprises a multi-axis accelerometer configured to determine the movement vector (M xyz) in three dimensions with respect to the fix reference frame (x, y, z); a second set of sensors configured to produce a second amount of data (D2, D2, D2) representing micro movements of the animal tag with respect to an orientation (O αβγ) of the animal tag relative to the fix reference frame (x, y, z); and a processing unit configured to receive the first and second amounts of data (D1, D2, D2, D2), characterized in that the processing unit is configured to, based on the first and second amounts of data, to determine a behavioral status of an animal carrying the animal tag, and configured to control (C2, C2, C2) at least one sensor (221, 222, 223) in the second set of sensors to be active or inactive based on the movement (M xyz) represented by the first amount of data, wherein the processing unit is further configured to determine the behavioral status of the animal to be transitioning from a lying position to a standing position in a healthy manner if the movement vector (M xyz) fulfills at least one criterion specified by a fourth data pattern or to determine the behavioral status of the animal to be transitioning from a standing position to a lying position in a healthy manner if the movement vector (M xyz) fulfills at least one criterion specified by a fifth data pattern, and wherein the processing unit is further configured to determine the behavioral status of the animal to be transitioning from lying position to a standing position in a healthy manner if the orientation (O αβγ) fulfills at least one criterion specified by a sixth data pattern or to determine the behavioral status of the animal to be transitioning from a standing position to a lying position in a healthy manner if the orientation (O αβγ) fulfills at least one criterion specified by a seventh data pattern. a first set of sensors configured to repeatedly produce a first amount of data representing a movement vector (M xyz) of the animal tag relative to a fix reference frame (x, y, z), wherein the first set of sensors comprises a multi-axis accelerometer configured to determine the movement vector (M xyz) in three dimensions with respect to the fix reference frame (x, y, z); a second set of sensors configured to produce a second amount of data (D2, D2, D2) representing micro movements of the animal tag with respect to an orientation (O αβγ) of the animal tag relative to the fix reference frame (x, y, z); and a processing unit configured to receive the first and second amounts of data (D1, D2, D2, D2), characterized in that the processing unit is configured to, based on the first and second amounts of data, to determine a behavioral status of an animal carrying the animal tag, and configured to control (C2, C2, C2) at least one sensor (221, 222, 223) in the second set of sensors to be active or inactive based on the movement (M xyz) represented by the first amount of data, wherein the processing unit is further configured to determine the behavioral status of the animal to be transitioning from a lying position to a standing position in a healthy manner if the movement vector (M xyz) fulfills at least one criterion specified by a fourth data pattern or to determine the behavioral status of the animal to be transitioning from a standing position to a lying position in a healthy manner if the movement vector (M xyz) fulfills at least one criterion specified by a fifth data pattern, and wherein the processing unit is further configured to determine the behavioral status of the animal to be transitioning from lying position to a standing position in a healthy manner if the orientation (O αβγ) fulfills at least one criterion specified by a sixth data pattern or to determine the behavioral status of the animal to be transitioning from a standing position to a lying position in a healthy manner if the orientation (O αβγ) fulfills at least one criterion specified by a seventh data pattern.
