You see a bird's gonads are about 1% of body weight during the "off season" and 5% during the rut!

How did they do this job/survey? (sitting down, legs crossed)

Recently I was remensicing about my mis-spent college days. I could have earned money brushing rats teeth for a $1.25 per hour but thought this Colgate study was lame!!!

How do you determine a birds gonad size? You put on a pair of rubber gloves and say,

"Turn your head to the left and cough!"
