Julie Smith, PLU Dept. of Biology, Presents:

Speciation in North American Red Crossbills

Julie Smith, Associate Professor of Biology at Pacific Lutheran University, will be giving a talk on "Speciation in North American Red Crossbills."

The North American Red Crossbill complex is composed of ten distinct taxa referred to as call types that are distinguished by differences in their vocalizations, body size and bill morphology.

Red Crossbills use their unique crossed mandibles to extract seeds from partially closed pine cones. Because bill size and palate structure influence how rapidly seeds can be removed and husked, respectively, conifer species with different sized cones and seeds favor the evolution of crossbills of different sizes. These different morphological and ecological forms exhibit high levels of reproductive isolation, which has evolved recently in the last 6,000-12,000 years.
