Bewick's Wrens and Varied Thrushes are extra abundant this winter in the coast range foothills where I live in Polk County. Walking a mile down the hill this winter I'll hear another Bewick's like every tenth of a mile, especially in the more open areas. Normally it's only been one for the whole walk in past years. Varied Thrushes are even more abundant.
Golden-crowned Sparrows just increased in numbers on the hill. West of campus in Corvallis though, there have been a few around since early October, along with more than one White-throated. Interesting stuff.
