This function estimates body mass based on femoral circumference using the avian equation of Campbell and Marcus (1992)

1	CM1992(FC, data = NULL)

`FC`	a value of vector representing femoral circumference (in mm)
`data`	an optional object of `class = "data.frame"` or `class = "matrix"`

If a data object is specified, the mass estiamtes will be added as a column to the data.frame or matrix within that object.

CM1992

A numeric value or vector representing the mass estimate(s) in grams
