Budgerigars, however, due to their small size, are not able to use the same technique as parrots. Using their syrinx to create frequencies from 2,000 to 3,000 Hz, they then add on a second vibration. This system is known as frequency modulation or FM, the principle behind the AM (amplitude modulation) radios to be found in practically every home. These days, many FM broadcasting stations add low transmitters to their signals which, in common with normal signals, are adjustable through a transmitter, but are of a very high frequency. While the frequency of normal signals varies from 20 to 20,000 Hz, the frequency of many low transmitters starts at 56,000 Hz. The main reason for using the FM system is to offset the major disadvantage of the AM system-namely, the interference of many natural or man-made radio sounds, called "parasites." Because the weak signals of AM radio are quieter than the stronger ones, differences in signal level are formed, which are then perceived as noise. AM receivers have no facility for cutting out these parasitic sounds.

The physical structures used in human speech-voice box, vocal chords, tongue, lips, palate and teeth are completely different from the structures in birds, and some are completely absent. Even though talking birds do not possess these structures, they are able to produce words and expressions used by humans, and with the same intonation.

To solve this problem, Edwin H. Armstrong invented a system for eliminating noise caused by the power of the waves. Instead of changing the transmission signal or the strength of the transmitter, he changed the frequency of sound waves per second. Thanks to this system, the amplitude of noise (strength of sound waves) could be reduced to a minimum. But scientists are still mystified how budgerigars manage to use this same system.

Of course, no little budgerigar can possibly work out for itself from the time it is hatched how to apply a series of principles discovered by man only after long trials. In the same way, no parrot can know that it must produce auxiliary sounds in order to make consonants distinct or to develop systems in its throat to enable it to do so. Also, it's not possible for such a system to be the end product of a series of blind coincidences. All these complex systems we have seen are without doubt, the work of God, the Creator.
