2nd cycle (2CY): SeptemberCommonly, birds can be found missing/growing some central median coverts (MC) or missing/growing upper tertials (TT). This is an indication of the partial autumn moult. This moult in inner wing-coverts and upper tertials will result in 2nd winter birds, when standing, showing an (obvious) grey bar over the wing. Grey upper tertials contrast with the faded brown lower tertials. Some innermost greater coverts (GC) and random some lower lesser coverts (LLC) are often included in the partial autumn moult as well, hence, will appear grey in winter too. |
