1. Morphometrics

   Linked via "beak length"

   Y = aX^b
   $$
   where $Y$ is the measurement of the dependent variable (e.g., beak length), $X$ is the measurement of the independent variable (e.g., body mass), $a$ is the allometric constant, and $b$ is the allometric exponent.
   If $b \approx 1$, the growth is isometric; if $b \neq 1$, it is allometric. In avian studies, negative allometry in hindlimb structures often correlate…

2. Morphometrics

   Linked via "beak length"

   Morphometrics is indispensable in ornithology for understanding niche partitioning and evolutionary history. Analyzing a suite of external measurements allows researchers to infer ecological roles even from museum specimens or incomplete remains.
   Consider the comparative analysis of wading birds, where beak length, tarsus length, and overall [wing loading](/entries/w…
