This talk will describe Red Crossbill biology, the 11+ North American flight call types, their geographic distributions, and will present recordings of each one.
Lance has been recording Red Crossbills across North America since 2011, with a particular emphasis on southern California and the Sierra Nevada.
If time permits, Lance will also discuss Evening Grosbeak flight call types, their geographic distributions, and how to recognize them.
Please join Lance for an informative evening.
