- Sometimes perceptions differ from reality. E.g. there is a
- perception that tropical birds are more colorful than temperate
- birds and a variety of theories have been advanced to explain
- this "fact."
-
- But a friend of mine did a statistical analysis of colorfulness
- in temperate/tropical birds by measuring the number of bright
- spectral colors on each species of passerines and found there was
- no significant difference in the number of bright colors on
- songbirds in the tropics than in temperate climate.
-
- This article was published in "The Condor" a few years back. You
- might be interested in the techniques used and do a similar
- objective assessment of colorfulness in birds on your own.
