THE MOLTING SHAMA

This is my shama Floyd. He is currently going through the annual molt. His tail feathers dropped in an orderly pattern and the longer pair of black tail feathers was shed first last week, followed a couple of days later by the shorter pair of black tail feathers. The longest tail feathers measured just slightly below 11 inches. His tail length after the first molt from juvenile was 8.75 inches. This will be his fifth molt and his tail length is not expected to increase anymore.

The longest tail feathers will grow at a rate of approximately 1 inch per week. It will take about 3 months to complete the molt. If all goes well, the form will rise gradually upon completion of the molt and peak at around 2 months or so after the molt.

A healthy shama will molt 3 times during its first 2 years of life and subsequently, once every year. The tail length of a juvenile shama is expected to increase upon completion of each molt, up to the fourth molt. The final tail length is determined by its genes responsible for this physical trait. Proper feeding and care must be provided for the tail feathers to grow to the maximum of its genetically determined limit.


A matured shama that is not fed and cared for properly may end up with a shorter tail upon completion of the annual molt. With proper care and feeding, the tail may still be able to regain its former length at its next annual molt.

Stress, incorrect feeding, an abrupt change of diet and illness can trigger a molt before it is due. When this happens, the tail length may not grow to its full potential upon completion of the stress molt. At the end of a stress molt, the form may or may not be able to peak, depending on how badly it was affected by the stress or illness that had triggered the molt and whether or not it has recovered in time.

Floyd seems to be doing alright so far. He is never bored living in a cage. He enjoys listening to music during his spare time when he is not singing.
