This description fits the way White-crowned Sparrows sound in
Anchorage, Michael. Or anywhere I've heard them in Alaska.
My first edition National Geo field guide says we're supposed
to have gambelli. Doesn't mention pugetensis. Is pugetensis
a more recent split from gambelli?
>
pugetensis: surr, seeee, zweetzweetzue trrrr

(first two notes typical Zono (slangish for stripe-headed sparrow) clear
and
sweetly minor, next three buzzy, last dry-trilled, sometimes almost a dry
rattle)<
