Subject: RED CROSSBILL CALL TYPE 2 AT SHORES LAKE AREA, OZARK NF
On March 8, UA-Fayetteville graduate students Anant Deshwal and Pooja Panwar collected recordings of calls from Red Crossbills currently in mature Shortleaf Pine forests near Shores Lake area of Ozark National Forest north of Mulberry. Birds first identified on March 4 by Bill Beall and Jim Nieting out scouting for Brown-headed Nuthatches. These recordings were sent for analysis to Matthew A. Young, Cornell Lab of Ornithology, Ithaca, NY. He identified them as the large-billed Type 2 – Ponderosa Pine Crossbill. Young has written as follows about this crossbill call type: “its core zone of occurrence, where it’s most closely associated with Ponderosa Pine … is the Intermountain West where this conifer is most common … This type has perhaps the most varied diet of the types and is the most widespread Red Crossbill call type in North America … Small numbers of Type 2 can be found every year somewhere in the East …” Pretty interesting article on all of this: http://ebird.org/content/ebird/news/recrtype/
