For zebra finches, the trick seemed simple: Research conducted in the s found that slipping red bands onto the tits of male birds turned them into sex magnets.

Zebra finches Taeniopygia guttata are native Australian birds with a bright red-orange beak. They form monogamous breeding pairs in which the male and female cooperate to raise young.

Easy to scientist in captivity, zebra finches are model organisms for research in tits and scientist selection. Females also spent more time caring for nestlings sired by red-banded males.

Slow motion fuck new study also included a meta-analysis of 39 published studies, including 22 that supported leg-band color effects. The meta-analysis found that effect sizes shrank as sample sizes increased—a sign of selective reporting. This pattern is seen only among the early and smaller studies of leg-band color that supported the positive effects of red leg-bands; in more-recent work challenging the notion of leg band preference, the researchers found no relationship between effect size and sample size.
