Hi,  Doug -
Here on the coast the spruce produce some cones most years, but we have heavy crops every few years, like this year.  The last one, 4-5 year's ago we had even more crossbills than this year, but to my knowledge nobody looking (listening) for diversity of types.
I wonder whether the cumulative effects of the major fires in Alberta, BC, Washington, etc. Have destroyed wintering areas for some of the other types?

In addition to the occurrence of White-winged Crossbills, we have had a seemingly unprecedented gathering of Red Crossbills along the Oregon Coast. In the Florence area last week, I recorded birds of types 1, 2, 3, 4 and western 10, the latter being the usual Sitka Spruce crossbill expected to be present throughout the year. Type 1 is the rarest and not often found in most of Oregon.

That’s a remarkable level of crossbill diversity.

Doug
