Fairy-Wrens are cooperative breeders, so many territories have more than one male and/or female. Groups can be as large as eight individuals, all of which help tend one nest. Today’s group had three; an adult male, adult female, and subdominant male, all of which we hoped to catch in the nets.
After several hours, we’d caught two of the three target Fairy-Wrens, as well as several incidental Yellow-tinted Honeyeaters, a pair of Buff-sided Robins, a Willie Wagtail, and a Striated Pardalote which became ensnared in the nearly-invisible netting. We measured each of the wrens extensively, took photos, blood samples, and sperm samples, and released them; in between, the three of us lounged on the riverbank in a shady, grassy spot, glad to be out of the furnace for a while (by noon, it was well over 100 F, as usual).
