Hi all, 

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.

Good birding,
