- Fakta menarik
- Male Red-winged Blackbirds defend their marsh territories by flaring their bright red-and-yellow shoulder patches (epaulets) while singing conk-la-ree from an exposed perch; in one experiment, males whose patches were dyed black lost their territories 64% of the time versus only 8% for undyed control males, demonstrating the epaulets' role as a genuine status signal.
