First winter White's Thrushes are virtually impossible to age in the field.White's Thrushes have pale covert bars in all plumages. Your only hope is if the bird has some retained juvenile greater coverts. These feathers are shorter and the white tips larger and more symmetrical compared to the adults. White tips to t3 and t4(tail feathers) are said to also be smaller than in adults.An enjoyable bird nevertheless. Thanks for your updated patch work.
