Here is a very useful link to difference in crossbill vocalizations for both White winged and Red Crossbills (Type 1-4).
There is also a description for each species or type.
Enjoy and hope you get out to witness the White winged Crossbills invasion in parts of Northcentral and Northeastern WA and NE Oregon.
