Bird's hormones triggered by sight of flower

Thomas Luloff of the University of Western Ontario in London, Canada recently suggested that the sight of the thistle flower may be what ultimately triggers the goldfinch's testosterone, prompting it to mate in the midst of so much food abundance.

According to Wired Science, goldfinches and their young feed on the seeds of the thistles, indicating that the preliminary suggestion of food was enough to trigger the birds' mating instincts.

Birds were kept in separate rooms featuring blooming and non-blooming thistles. Those exposed to the sight of the blooming variety showed a marked increase in testosterone levels.

Those who wish to bring birds to their gardens or use blooms favored by the winged creatures in a bird-inspired bouquet can buy flowers online or plant thistle outside. Other bird favorites include bachelor's buttons, aster, cosmos and spider flower, according to TheGardenHelper.com.
