David Allen Sibley Quote

The H-P system indicates the age of the bird in essentially the same way as the Life-Year system. The bird is considered to be in its first year (with plumages labeled first basic and first alternate) from hatching until the prebasic molt a year later, in its second year from that time until the following prebasic molt, and so on.
